28 in 21 in., 20 in.
Is this a right triangle?

Answers

Answer 1

Answer:

No, it is not a right triangle.

Step-by-step explanation:

The simplest way to determine is testing out the numbers with Pythagorian theorem.

If it complies with the theorem, it is a right triangle.

let's assume c = 28, b = 21, and a = 20

the longest side is the hypotenuse so side c (28 in) will be the hypotenuse.

According to the Pythagorian theorem, the square of the length of hypotenuse must equal to the sum of squares of other two sides.

check:

c^2 = 28^2 = 784

a^2 + b^2 = 21^2 + 20^2 = 841

because c^2 is not equal to a^2 + b^2, the triangle is not a right triangle.

A 40 of foxes in a wildlife preserve quadruples in size every 13 years. The function y=40•4^4, where x is the number of 13-year period, models the population growth. How many foxes will there be after 26 years

Answers

Answer:

640 foxes

Step-by-step explanation:

The actual formula is [tex]y = 40 * 4^{x}[/tex]

Now that we have the real formula we would need to find out how many 13 year periods exist in the 26 years that are being used in the question. We calculate this by simply dividing 26 by 13.

26 / 13 = 2 periods

Therefore, now that we know there are 2 periods of 13 years in the 26-year span, we plug this value into the formula and solve for y...

[tex]y = 40 * 4^{x}[/tex]

[tex]y = 40 * 4^{2}[/tex]

[tex]y = 40 * 16[/tex]

[tex]y = 640[/tex]

Finally, we can see that there should be 640 foxes after 26 years.

examine the graph below. select the solutions to the graph from the following points. select three that apply.

Answers

Answer:

Options (1), (2), (3)

Step-by-step explanation:

Let the equation of the line is,

y = mx + b

Here m = slope of the line

b = y-intercept

Given line on the graph is passing through two points (-3, 0) and (0, 1).

Slope of this line will be,

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

   = [tex]\frac{1-0}{0+3}[/tex]

   = [tex]\frac{1}{3}[/tex]

y-intercept of the line 'b' = 1

Equation of the line will be,

y = [tex]\frac{1}{3}x+1[/tex]

If the points given in the options satisfy the equation, they will be the solution of the line.

Option (1),

For (3, 2),

2 = [tex]\frac{3}{3}+1[/tex]

2 = 2

True.

(3, 2) is the solution.

Option (2)

For (21, 8),

8 = [tex]\frac{21}{3}+1[/tex]

8 = 8

True.

(21, 8) is the solution.

Option(3)

For (-15, -4),

-4 = [tex]\frac{-15}{3}+1[/tex]

-4 = -4

True.

(-15, -4) is the solution.

Option (4)

For (12, 9)

9 = [tex]\frac{12}{3}+1[/tex]

9 = 5

False

(12, 9) is not the solution.

Option (5)

For (-6, 1)

1 = [tex]\frac{-6}{3}+1[/tex]

1 = -1

False

(-6, 1) is not the solution.

Therefore, Options (1), (2), (3) are the solutions.

Office Depot prints black and white or colored copies.Yesterday,they printed 9 black and white copies for every 2 colored copies if they print 200 color copies how many black and white copies were printed?

Answers

Answer:

900 black and white copies were printed.

Step-by-step explanation:

From the information provided, you know that they printed 9 black and white copies for every 2 colored copies and you can use a rule of three to find the amount of black and white copies that were printed if they printed 200 color copies:

9 black and white → 2 colored

             x               ← 200 colored

x=(9*200)/2=900

According to this, the answer is that 900 black and white copies were printed.

4x³ + 3x² - 2x - 1 =(4x³ + 2x²) + (x² + 1/2x) - (5/2x + 5/4) + 1/4 =2x²(2x+1) + 1/2x(2x + 1) - 5/4(2x + 1) + 1/4 =(2x + 1)(2x² + 1/2x - 5/4) + 1/4

This equation shows how the total amount of paper Shelby's office has recycled depends on the number of weeks since they started the new recycling plan. p = w + 14. The variable w represents the number of weeks the office has been on the new recycling plan, and the variable p represents the total kilograms of paper recycled. How many weeks will it take Shelby's office to recycle a total of 16 kilograms of paper?

Answers

Answer: 2 weeks

Explanation: Since we know that p represents the amount of paper recycled, we can write the new equation as 16=w+14. When you solve that equation you get an answer of 2=w

The stopping distance (s) of a truck varies directly as the square of its speed (v). If a truck travelling at 50 mph requires 200 feet to stop, find the stopping distance for a truck travelling at 65 mph.

Answers

Answer:

The distance is 338ft

Step-by-step explanation:

Given

Represent distance with s and velocity with v:

When

[tex]s = 200\ ft[/tex]

[tex]v = 50mph[/tex]

Required

Determine the distance when velocity is 65mph

From the question, we understand that:

[tex]s\ \alpha\ v^2[/tex]

Convert to equation

[tex]s\ = kv^2[/tex]

Substitute 200 for s and 50 for v

[tex]200 = k * 50^2[/tex]

[tex]200 = k * 2500[/tex]

Make k the subject:

[tex]k = \frac{200}{2500}[/tex]

[tex]k = \frac{2}{25}[/tex]

To get s when v = 65.

Substitute 65 for v and 2/25 for k in [tex]s\ = kv^2[/tex]

[tex]s = \frac{2}{25} * 65^2[/tex]

[tex]s = \frac{2}{25} * 4225[/tex]

[tex]s = \frac{8450}{25}[/tex]

[tex]s = 338\\[/tex]

Hence, the distance is 338ft
