2.1.2. What is the sum of handshakes that will be made by the first and second ​

The equation y = |x - 5| + |x + 5| can be rewritten as:

y = { -2x - 10, for x < -5,

 { 10, for -5 ≤ x ≤ 5,

 { 2x + 10, for x > 5.

When -5 < x < 5, both |x - 5| and |x + 5| are non-negative. So we can rewrite y = |x - 5| + |x + 5| as follows:

If x < -5, then x - 5 < -5 and x + 5 < 0, so we have:

y = -(x - 5) - (x + 5) = -2x - 10

If -5 ≤ x ≤ 5, then x - 5 < 0 and x + 5 ≥ 0, so we have:

y = -(x - 5) + (x + 5) = 10

If x > 5, then x - 5 ≥ 0 and x + 5 > 5, so we have:

y = (x - 5) + (x + 5) = 2x + 10

Therefore, the equation y = |x - 5| + |x + 5| can be rewritten as:

y = { -2x - 10, for x < -5,

 { 10, for -5 ≤ x ≤ 5,

 { 2x + 10, for x > 5.

Given question is incomplete, the complete question is below

Rewrite each equation without absolute value for the given conditions. y = |x-5| + |x+5| if -5 < x < 5

x = 0, π, 2π, 3π, 4π, 5π, 6π, π/3, 5π/3

These are the exact solutions of the given equation on the interval [0, 21). To find all exact solutions of the equation sec(x) sin(x) - 2 sin(x) = 0 on the interval [0, 21), we will use the factoring method:

First, we can factor out the sin(x) term:

sin(x) (sec(x) - 2) = 0

Now, we have two separate equations to solve:

1) sin(x) = 0
2) sec(x) - 2 = 0

For equation (1), sin(x) = 0 at x = nπ, where n is an integer. We need to find the values of n that give solutions in the range [0, 21):

0 ≤ nπ < 21
0 ≤ n < 21/π
n = 0, 1, 2, 3, 4, 5, 6

x = 0, π, 2π, 3π, 4π, 5π, 6π

For equation (2), sec(x) - 2 = 0, or sec(x) = 2. We know that sec(x) = 1/cos(x), so:

1/cos(x) = 2
cos(x) = 1/2

The values of x for which cos(x) = 1/2 in the range [0, 21) are x = π/3 and x = 5π/3.

Combining both sets of solutions, we have:

x = 0, π, 2π, 3π, 4π, 5π, 6π, π/3, 5π/3

These are the exact solutions of the given equation on the interval [0, 21).

The number of milligrams of sugar his spoon holds is 1250 milligrams.

To find out how many milligrams of sugar Chad's spoon holds, we first need to know how much sugar he removed in total. To do this, we can subtract the amount of sugar he needed (280 grams) from the amount he poured (295 grams).

295 grams - 280 grams = 15 grams

Next, we need to divide the total amount of sugar Chad removed (15 grams) by the number of spoonfuls he used (12).

15 grams ÷ 12 = 1.25 grams per spoonful

Finally, we can convert grams to milligrams by multiplying by 1000.

1.25 grams x 1000 = 1250 milligrams

Therefore, Chad's spoon holds 1250 milligrams of sugar.

It's important to note that when cooking or baking, precise measurements are crucial to the success of the recipe. Even small changes can greatly affect the outcome. While it's great that Chad was able to remove the excess sugar, it's best to be as accurate as possible from the start.

Lee spent a total of 33 hours working on all the lawns, as calculated by multiplying the number of lawns for each size category by the respective time required for mowing, trimming, and sweeping.

In order to determine the total number of hours Lee spent working on all the lawns, we need to calculate the time for each task separately. For the average size lawn, Lee takes 1 hour to mow and 2 hours to trim and sweep, totaling 3 hours per lawn. For the large size lawn, Lee takes 3 hours to mow and 3 hours to trim and sweep, totaling 6 hours per lawn.

Given that Lee mowed, trimmed, and swept 5 average size lawns and 3 large size lawns in one week, we can calculate the total hours as follows:

Total hours for average size lawns = 5 lawns * 3 hours/lawn = 15 hours

Total hours for large size lawns = 3 lawns * 6 hours/lawn = 18 hours

Therefore, the total hours Lee spent working on all the lawns is 15 hours + 18 hours = 33 hours.

Answer:

push-up = 1 second

sit-up = 3 seconds

Step-by-step explanation:

let p represent the # of push-ups

let s represent the # of sit-ups

System of equations:

19p+8s=43

12p+12s=48

i'll eliminate s by multiplying the top equation by 3 and the bottom equation by -2

57p+24s=129

-24p-24s=-96

33p=33

p=1 second

now solve for s (i'll plug p into the 2nd equation)

12(1) + 12s=48

12s=36

s=3 seconds

The p-value is 0.00012 which is less than the significance level (α = 0.1), we reject the null hypothesis and conclude that there is sufficient evidence to support the alternative hypothesis that the true population proportion is different from 0.77.

The hypothesis being tested is:

H0: p=0.77 (null hypothesis)

H1: p≠0.77 (alternative hypothesis)

where p is the true population proportion.

The test statistic for this hypothesis test is the z-score, which can be calculated using the formula:

z = (x - np) / sqrt(np(1-p))

where x is the number of successes, n is the sample size, and p is the hypothesized proportion under the null hypothesis.

In this case, n = 500, x = 370, and p = 0.77. Plugging these values into the formula, we get:

z = (370 - 500 * 0.77) / sqrt(500 * 0.77 * 0.23)

z ≈ -3.81

The p-value for this test is the probability of obtaining a z-score more extreme than -3.81, assuming the null hypothesis is true. Since this is a two-tailed test, we need to calculate the area in both tails of the standard normal distribution. Using a standard normal distribution table or a calculator, we find that the area in each tail is approximately 0.00006.

Therefore, the p-value is:

p-value ≈ 2 * 0.00006 = 0.00012

In terms of practical interpretation, we can say that there is evidence to suggest that the proportion of successes is significantly different from 0.77 in the population from which the sample was drawn.

2) To add these fractions, you need to find a common denominator. The smallest common multiple of 7 and 9 is 63, so we can write:

3/7 * 9/9 + 2/9 * 7/7 = 27/63 + 14/63 = 41/63

3) To add these fractions, you need to find a common denominator. The smallest common multiple of 5 and 15 is 15, so we can write:

3/5 * 3/3 + 1/15 * 1/1 = 9/15 + 1/15 = 10/15

But we can simplify this fraction by dividing both the numerator and denominator by 5:

10/15 = 2/3

4) To add these fractions, you need to find a common denominator. The smallest common multiple of 9 and 8 is 72, so we can write:

1/9 * 8/8 + 7/8 * 9/9 = 8/72 + 63/72 = 71/72

5) To add these fractions, you need to find a common denominator. The smallest common multiple of 7 and 21 is 21, so we can write:

6/7 * 3/3 + 2/21 * 1/1 = 18/21 + 2/21 = 20/21

6) To add these fractions, we need to find a common denominator first. The smallest number that both 6 and 10 divide into is 30. So, we convert 4/6 to 20/30 by multiplying both the numerator and denominator by 5, and we convert 2/10 to 3/15 by multiplying both the numerator and denominator by 3. Now we have:

20/30 + 3/15 = (20x1 + 3x2)/(30x2) = 23/60

Therefore, 4/6 + 2/10 = 23/60.

7) To add these fractions, we need to find a common denominator first. The smallest number that both 11 and 22 divide into is 22. So, we convert 1/11 to 2/22 by multiplying both the numerator and denominator by 2, and we convert 3/22 to 3/22 (it is already in terms of 22). Now we have:

2/22 + 3/22 = (2 + 3)/22 = 5/22

Therefore, 1/11 + 3/22 = 5/22.

8) To add these fractions, we need to find a common denominator first. The smallest number that both 4 and 20 divide into is 20. So, we convert 1/4 to 5/20 by multiplying both the numerator and denominator by 5, and we convert 8/20 to 8/20 (it is already in terms of 20). Now we have:

5/20 + 8/20 = (5 + 8)/20 = 13/20

Therefore, 1/4 + 8/20 = 13/20.

9) To add these fractions, we need to find a common denominator first. The smallest number that both 7 and 9 divide into is 63. So, we convert 4/7 to 24/63 by multiplying both the numerator and denominator by 3, and we convert 2/9 to 14/63 by multiplying both the numerator and denominator by 7. Now we have:

24/63 + 14/63 = (24 + 14)/63 = 38/63

Therefore, 4/7 + 2/9 = 38/63.

10) To add these fractions, we need to find a common denominator first. The smallest number that both 10 and 30 divide into is 30. So, we convert 6/7 to 18/30 by multiplying both the numerator and denominator by 3, and we convert 2/30 to 1/15 by multiplying both the numerator and denominator by 15. Now we have:

18/30 + 1/15 = (18x1 + 1x2)/(30x2) = 37/30

Therefore, 6/7 + 2/21 = 37/30.

A geometric sequence is a type of sequence where each term is found by multiplying the previous term by a constant factor. This means that each term is a multiple of the one before it. In contrast, an arithmetic sequence is a type of sequence where each term is found by adding a constant value to the previous term.

This means that each term is a sum of the one before it and a fixed value.

To answer your question, whether a geometric sequence will always grow faster than an arithmetic one depends on the values of the constant factor and fixed value in each sequence. In general, if the constant factor in a geometric sequence is greater than 1, the terms will grow at an increasingly faster rate than in an arithmetic sequence.

However, if the constant factor is between 0 and 1, the terms will grow at a decreasing rate, meaning that the sequence will actually grow more slowly than an arithmetic one.

It's important to note that the rate of growth is not the only factor to consider when comparing geometric and arithmetic sequences. The actual values of the terms in each sequence can also differ significantly, depending on the starting term and the values of the common ratio and common difference.

In some cases, an arithmetic sequence may actually have higher values than a geometric one, even if it grows more slowly.

In summary, whether a geometric sequence will always grow faster than an arithmetic one depends on the specific values of each sequence. However, in general, if the constant factor in a geometric sequence is greater than 1, it will grow faster than an arithmetic sequence.

Answer: the minimum distance from P to the circle is approximately 2.97, and the maximum distance is approximately 3.89.

Step-by-step explanation:

To find the minimum and maximum distances from the point P(-3, 9) to the circle defined by (x-3)^2 + (y-1)^2 = 25, we can use the fact that these distances are given by the perpendiculars from the point P to the line passing through the center of the circle.

The center of the circle is (3,1), so we can find the equation of the line passing through P and the center of the circle as follows:

The slope of the line passing through P and the center of the circle is (1-9)/(3-(-3)) = -8/6 = -4/3.

Using the point-slope form of a line, the equation of the line passing through P and the center of the circle is y - 9 = (-4/3)(x + 3).

Now we can find the points where this line intersects the circle. Substituting y = (-4/3)(x+3) + 9 into the equation of the circle, we get:

(x-3)^2 + ((-4/3)(x+3) + 8)^2 = 25

Expanding and simplifying this equation gives a quadratic equation in x:

25x^2 + 96x + 80 = 0

Solving this quadratic equation using the quadratic formula, we get:

x = (-96 ± sqrt(96^2 - 42580)) / (2*25)

x = (-96 ± 56) / 50

x = -2.04 or x = -1.52

Substituting these values of x into y = (-4/3)(x+3) + 9 gives the corresponding values of y:

When x = -2.04, y = 6.24

When x = -1.52, y = 7.27

So the two points of intersection are approximately (-2.04, 6.24) and (-1.52, 7.27).

Finally, we can find the distances from P to each of these points using the distance formula:

The distance from P to (-2.04, 6.24) is sqrt[(-3 - (-2.04))^2 + (9 - 6.24)^2] ≈ 3.89.

The distance from P to (-1.52, 7.27) is sqrt[(-3 - (-1.52))^2 + (9 - 7.27)^2] ≈ 2.97.

Therefore, the minimum distance from P to the circle is approximately 2.97, and the maximum distance is approximately 3.89.

The best prediction for the bacteria population after 8 days is approximately 14,301.67 bacteria.

To find the predicted population of bacteria after 8 days, we need to apply the given growth rate of 220% per day to the initial population of 50 bacteria for each day, starting from day 1 and continuing to day 8.

For each day, the population of bacteria is expected to be 220% or 2.2 times the population of the previous day. So, we can use the formula:

P = P0 [tex]x (1 + r)^n[/tex]

where P is the predicted population after n days, P0 is the initial population, r is the growth rate per day (as a decimal), and n is the number of days.

Substituting the given values, we get:

P = 50[tex]x (1 + 2.2)^8[/tex]

P ≈ 14,301.67

The function notation is E(h) = 8.5h where h represents the number of hours worked so the domain is {0, 1, 2, 3, 4, 5} and the range is {0, 8.5, 17, 25.5, 34, 42.5}.

Let E(t) be John's earnings in dollars after working t hours, where t is in the domain 0 ≤ t ≤ 5. Then E(t) = 8.50t, since John earns $8.50 per hour proofreading ads.

The domain of the function is 0 ≤ t ≤ 5, since John works no more than 5 hours per day.

The range of the function is 0 ≤ E(t) ≤ 42.50 since John earns $8.50 per hour and works no more than 5 hours per day.

Therefore, the maximum earnings he can make in one day is 5 hours multiplied by $8.50 per hour, which equals $42.50.

The minimum earnings are $0, which would occur if John does not work at all.

It appears to be setting up a proportion between the central angle of the sector and the ratio of arc length to the circumference of the circle, rather than the ratio of the central angle to the full angle of the circle. Then the area should equal  to 126.9 [tex]ft^2.[/tex]

To find the area of sector XZY, we need to know the measure of angle XYZ. However, the given equation n/360 = 115/225 is incorrect, as it appears to be setting up a proportion between the central angle of the sector and the ratio of arc length to the circumference of the circle, rather than the ratio of the central angle to the full angle of the circle.

To find the correct measure of angle XYZ, we need to use the formula:

Area of sector XZY = (n/360) x π[tex]r^2[/tex]

where r is the radius of circle Z.

We know that the area of circle Z is 255 square feet, so we can find the radius as follows:

Area of circle Z = π[tex]r^2[/tex]

255 = π[tex]r^2[/tex]

[tex]r^2[/tex] = 81

r = 9

Now we can solve for n using the given ratio of 115/225:

n/360 = 115/225

n = (115/225) x 360

n = 184.32

Rounding to the nearest tenth, we get:

n ≈ 184.3

Finally, we can find the area of sector XZY as:

Area of sector XZY = (n/360) x π[tex]r^2[/tex]

Area of sector XZY = (184.3/360) x π[tex](9)^2[/tex]

Area of sector XZY ≈ 126.9 [tex]ft^2[/tex]

we can simplify |x + 3| to x + 3 when x is greater than 5.

The absolute value function |x| is defined as the distance of x from zero on the number line. This means that |x| is always non-negative, so it can be expressed as a non-negative number.

In this case, we are given that x > 5, which means that x is greater than 5. If we add 3 to both sides of this inequality, we get:

x + 3 > 5 + 3

x + 3 > 8

This tells us that x + 3 is also greater than 8. Therefore, when x is greater than 5, the expression |x + 3| represents the distance of x + 3 from zero, which is equal to x + 3 itself because x + 3 is positive.

As a result, we can simplify |x + 3| to x + 3 when x is greater than 5.
