Step-by-step explanation:

The perimeter of the triangle is the sum of all of its side lengths

P=a+b+c

If a=5h-4k

b=10h+7m

c=5m-2k

Then the formula would be

P=(5h-4k)+(10h+7m)+(5m-2k)

P=15h-6k+12m

The required direction of the inequality is below the line.

If you're not graphing a vertical line, the inequality's sign will tell you which half-plane to shade. Shade above the line when using the  or > sign. Shade below the line if the symbol or is used. Larger solutions are to the right and smaller solutions are to the left, respectively, for a vertical line.

To check the direction, we will take points from the graph and put in the given inequality.

At point (2, 0)

y ≤ x/4 - 3

0 ≤ 2/4 - 3

0 ≤ -25

It is false

Again

At (2, -4)

y ≤ x/4 - 3

-4 ≤ 2/4 - 3

-4 ≤ -2.5

It is true,

Thus, we can say the direction of the inequality is below the line.

Step-by-step explanation:

The ball reaches a height of 40 meters at approximately 3.38 seconds after it is kicked.

To determine if the ball reaches a height of 40 meters, we can substitute h(t) = 40 into the equation and solve for t.

40 = -2t² + 4t + 27

Rearranging the terms, we get:

2t² - 4t - 13 = 0

We can solve for t using the quadratic formula:

t = [4 ± √(4² - 4(2)(-13))]/(2(2))

t = [4 ± √(176)]/4

t ≈ 3.38 or t ≈ -0.88

Since time cannot be negative, we can discard the negative solution. Therefore, the ball reaches a height of 40 meters at approximately 3.38 seconds after it is kicked.

The scale factor between a square of dimensions 7 by 7 and a scaled copy of dimensions 21/2 by 21/2 is 3/2 or 1.5.

We know that the dimensions of the square on the left are 7 by 7, and the dimensions of the square on the right are 21/2 by 21/2.

To find the scale factor, we can divide the dimensions of the square on the right by the dimensions of the square on the left

scale factor = (21/2) / 7

We can simplify this fraction by dividing both the numerator and the denominator by the greatest common factor, which is 7

scale factor = (21/2) / 7 = (21/2) * (1/7) = 3/2

Therefore, the scale factor is 3/2, or 1.5.

When -3 (row 1) is added to row 2, the result would be [ 1 - 4 | 8 ]

[ 0 10 | 10 ].

The first thing to do is to multiply each element in row 1 by - 3 :

- 3 x 1 = - 3

- 3 x - 4 = 12

- 3 x 8 = - 24

Then, we need to add the result to the elements in row 2:

3 + ( - 3 ) = 0

- 2 + 12 = 10

10 + ( - 24 ) = - 14

Exactly one-year later,

(a) Mean of the ages will be 13 years and 3 months.

(b) Range of the ages will be same 2 years and 7 months.

Part (a) : To find the mean of the ages of the same group of students exactly one year later, we add one year to each student's age and find the new mean.

New mean is : 12 years and 3 months + 1 year = 13 years and 3 months;

So the mean of the ages of the same group of students exactly one year later is 13 years and 3 months.

Part (b) : The range of their ages would still be 2 years and 7 months because we are adding the same amount to all of their ages, the difference between the youngest and oldest member of the group would remain the same.

What is Acute angle ?

An acute angle is an angle that measures between 0 and 90 degrees. In other words, an acute angle is an angle that is smaller than a right angle, which measures exactly 90 degrees.

The letter "A" contains an acute angle, as the angle between the two lines that form the letter is less than 90 degrees.

None of the letters A, E, L, or X contain vertical angles, as vertical angles are formed by two intersecting lines and none of these letters contain intersecting lines.

There are 6435 ways to direct the inquiries to any two of the firm's real estate agents.

What is combinations?

Combinations are a mathematical concept used to count the number of ways that a certain number of items can be selected from a larger set of items without regard to the order in which they are selected.

We can use combinations to solve this problem. We need to choose 8 inquiries out of 16 for the first agent, and the remaining 8 inquiries will be handled by the second agent.

The number of ways to choose 8 inquiries out of 16 is:

C(16, 8) = 16! ÷ (8! * (16-8)!) = 12870

This is the number of ways the inquiries can be directed to one agent. Since there are two agents and each handles 8 inquiries, we need to divide this number by 2 to avoid counting each arrangement twice:

12870 ÷2 = 6435

Therefore, there are 6435 ways to direct the inquiries to any two of the firm's real estate agents.

In mathematics, a scale factor is the ratio of matching measurements of an item to a representation of that thing. The copy will be bigger if the scaling factor is a full number. The duplicate will be smaller if the scaling factor is a fraction.

When the scale factor is less than one, you are going from big to small. You are dilating negatively.

When you are going from small to big, you scale factor is reversed. In this case, we had 1/2 in a, in b it became 2/1 which = 2.

Step-by-step explanation:he new balance on Guadalupe's credit card is calculated as follows:

First, we calculate the interest charged on the previous balance. Since the APR is 23%, the monthly interest rate is 23%/12 = 1.92%. So the interest charged on the previous balance for the month is:

Interest = Previous balance x Monthly interest rate

= $900.00 x 1.92%

= $17.28

Next, we add the finance charge, which is calculated as 1% of the previous balance plus any new charges. So the finance charge for the month is:

Finance charge = 1% x (Previous balance + New charges)

= 1% x ($900.00 + $0.00)

= $9.00

The total amount due is the sum of the previous balance, the interest charged, and the finance charge:

Total amount due = Previous balance + Interest + Finance charge

= $900.00 + $17.28 + $9.00

= $926.28

The minimum payment due is 2% of the total amount due, which is:

Minimum payment = 2% x Total amount due

= 2% x $926.28

= $18.53

If the minimum payment is less than $25, the minimum payment due is $25. So in this case, the minimum payment due is $25.

Guadalupe made a payment of $18.00, which is less than the minimum payment due, so she will be charged a late fee in addition to the interest on the unpaid balance.

The principal paid is the difference between the payment made and the interest charged, which is:

Principal paid = Payment - Interest

= $18.00 - $17.28

= $0.72

The new balance is the sum of the previous balance, any new charges, and the interest charged, minus the payment made, plus any finance charge and late fee:

New balance = Previous balance + New charges + Interest - Payment + Finance charge + Late fee

= $900.00 + $0.00 + $17.28 - $18.00 + $9.00 + $0.75

Answer:

0.00007003 is the standard form of 7.003x10^-5. In scientific notation, the number is expressed as 7.003 multiplied by 10 raised to the power of negative five. To convert it to standard form, the decimal point has to move to the left by five places since the exponent is negative. The resulting number is a decimal with four zeros before the first nonzero digit. Standard form is a way of representing numbers that does not use exponents and is useful in comparing and performing operations on numbers.

The circumference of the circle the bike tyre forms is equal to the distance travelled in one rotation of the tyre. The following formula determines a circle's circumference:

=> C = 2πr

where the mathematical constant is roughly equivalent to 3.14159 and r is the circle's radius.

Your bicycle tyre's radius in this instance is 12 inches. The tyre's circumference is as follows:

=> C = 2π(12) = 24π inches

The calculated distance between the tree and the zip line is 9.21 units

From the question, we have the following parameters that can be used in our computation:

y = -6/7x + 7

This represents the zip line

Convert the equation to standard form

This gives

7y = -6x + 49

So, we have

6x + 7y - 49 = 0

This means that

A = 6, B = 7 and C = -49

From the point (6, 14), we have

x = 6 and y = 14

The distance between the tree and the zip line is then calculated as

[tex]d = \frac{|ax + by + c|}{\sqrt{a^2 + b^2}}[/tex]

By substitution, we have

[tex]d = \frac{|6 * 6 + 7 * 14 - 49|}{\sqrt{6^2 + 7^2}}[/tex]
