Which two angles are supplementary

Answer:

Step-by-step explanation:

Given the various variance of normal body temperature expressed by the function f(t) = |98.6-x| where x is persons current body temperature in degree Fahrenheit.

If medical professional says that healthy individual cannot have a variance of no more than 0.5F, we can get the variance by substituting x = 0.5 into the modeled function as shown;

Note that the function can either be negative or positive because of the modulus sign

If x = 0.5

For positive value,

f(0.5) = 98.6-0.5

f(0.5) = 98.1

If the function is negative

f(0.5) = -(98.6-0.5)

f(0.5) = -98.6+0.5

f(0.5) = -98.1

The variance for healthy individual will be expressed as -98.1≤f(x)≤98.1

Moving downstream (with the current), the boat moves at a rate of (252 mi)/(12 h) = 21 mph. Upstream (against the current), it moves at a rate of (252 mi)/(84 h) = 3 mph.

When traveling downstream, the boat's speed is the sum of its own speed in still water and the speed of the current. It's the same going upstream, but the boat and current move in opposite directions. Let b and c denote these speeds, respectively. Then

downstream: b + c = 21 mph

upstream:      b - c = 3 mph

Adding these equations eliminates c and lets us solve for b :

(b + c) + (b - c) = 21 mph + 3 mph

2b = 24 mph

b = 12 mph

Now solve for c :

12 mph + c = 21 mph

c = 9 mph

Now Riley's made larger than normal payment in month

At 0 month, amount is $1,050

At 1 month, amount is $1,050

At 2 month, amount is $975

At 3 month, amount is $875

,

At 10 month, amount is $525

At 11 month, amount is $425

At 12 month, amount is $375

.

.

At 18 month, amount is $325

At 20 month, amount is $0

Thus, from the above Riley's made larger than normal payment in month 11

The intercept of month becomes 0 at 20 months.

Thus, Riley paid the entire balance after twenty months of payments

Therefore, Riley paid the entire balance after one year and eight months of payments.

Thus, the true statements are,

Step-by-step explanation:

1. We see that Shirley takes the train to work and back home. This means she takes the train twice a day. We also see that she uses the train five times a week. So step 1, multiple 5 and 2.

5x2 = 10

2. She pays $25 for a weekly train pass. Divide 25 and 10.

25/10 = 2.5

3. Now, we compare how much money she saved. Subtract 3.25 and 2.5.

3.25-2.5 = 0.75

4. This means she saved 75 cents by purchasing the weekly pass.

Answer:

B?

Step-by-step explanation:

The graph y = 2x + 5 can be represented by the image attached below.

The set of ordered pairings (x, y) where f(x) = y makes up the graph of a function.

These pairs are Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane in the general case when f(x) are real values.

Given, An equation y = 2x + 5, we can graph this by assuming some arbitrary values of 'x' that correspond to some arbitrary values of 'y'.

When x = 0, y = 5.

x = 1, y = 7 ⇒  (1, 7).

x = 5, y = 15 ⇒ (5, 15).

x = - 5, y = - 5 ⇒ (- 5, - 5).

x = - 2, y = 1 ⇒ (- 2, 1).

Answer: 17500

Step-by-step explanation: 7000 + 15000 + 22000 + 23000 +38000/ 6

The difference between a collection of numbers' highest and lowest values is known as the range.

The mean(average) salary exists 17500.

The range salary exists 35000.

Range, which shows statistical dispersion, is the size of the smallest interval in descriptive statistics that encompasses all the data. It is best suited to capturing the dispersion of tiny data sets because it only depends on two observations.

The difference between the highest and lowest values for a given data collection is the 35000in statistics. For instance, the range will be 10 - 2 = 8 if the given data set is 2, 5, 8, 10, and 3. As a result, the range may alternatively be thought of as the distance between the highest and lowest observation.

The salaries of six employees are $3000, $7000, $15,000, $22,000, $ 23,000, and $38,000.

a) Mean = Sum of terms / Number if terms

substitute the values in the above equation, we get

= 7000 + 15000 + 22000 + 23000 + 38000/ 6

= 17500

Therefore, the mean(average) salary exists 17500.

b) The maximum is $38,000 and the minimum is $3000 then the range exists

Range = maximum - minimum

substitute the values in the above equation, we get

Range = $ 38,000 - $ 3000

= $ 38,000 - $ 3000

= $ 35000

Therefore, the range salary exists 35000.

Explanation:

The remainder theorem says that if we divide some polynomial p(x) over (x-k), then p(k) is the remainder.

The expression x+1 is the same as x-(-1). Comparing this to x-k shows k = -1.

So we'll need to evaluate p(-1)

To do so visually, draw a vertical line through -1 on the x axis. Make sure this vertical line crosses the blue curve at some point, which I'll call point A.

From point A, draw a horizontal line to the y axis. You should reach y = 3.

This is all shown in the diagram below.

In other words, the point (-1,3) is on the blue curve, and p(-1) = 3.

So the remainder is 3.

Step-by-step explanation:

square has 4 sides each side is 10cm

The area of a square with a side length of 10 cm written in exponent form is  10² cm².

The perimeter of any given 2D figure is the sum of the lengths of all the sides.

We know the area of a square is a product of its two sides.

Assuming the length of a side of a square is a unit.

∴ The area of the square is (a×a) sq units,

and we know that a×a = a¹×a¹ = a¹⁺¹ = a².

So, given a square has a side length of 10cm.

∴ The area of the square will be (10×10) sq cm.

= 10² cm².

Answer:

Step-by-step explanation:

A: The charge of each electron is -1, so the charge of three electrons is -3. Removing something is denoted by a negative sign. The expression that represents the removal of three electrons from each of four atoms is (-3)(-4).

B: (-3)(-4) = (-1)(3)(-1)(4) = (-1)(-1)(3)(4) = 12

The net change in the charge for the group of atoms is 12 (or +12); that is, the charge of the atoms increases by 12.

C: Adding two electrons to each of six atoms results in a net change in charge of (-2)(6). Removing two protons from each of six atoms results in a net change in charge of (2)(-6).

D: (-2)(6) = (-1)(2)(6) = (-1)(12) = -12

(2)(-6) = (2)(6)(-1) = (12)(-1) = -12

E: The products are the same: -12.

F: If the signs of the numbers are the same, the product is positive. If the signs of the numbers are different, the product is negative.

Answer:

A)

The charge of each electron is -1, so the charge of three electrons is -3. Removing something is denoted by a negative sign. The expression that represents the removal of three electrons from each of four atoms is (-3)(-4).

B)

(-3)(-4) = (-1)(3)(-1)(4) = (-1)(-1)(3)(4) = 12

The net change in the charge for the group of atoms is 12 (or +12); that is, the charge of the atoms increases by 12.

C)

Adding two electrons to each of six atoms results in a net change in charge of (-2)(6). Removing two protons from each of six atoms results in a net change in charge of (2)(-6).

D)

(-2)(6) = (-1)(2)(6) = (-1)(12) = -12

(2)(-6) = (2)(6)(-1) = (12)(-1) = -12

E)

The products are the same: -12.

F)

If the signs of the numbers are the same, the product is positive. If the signs of the numbers are different, the product is negative.
