Find the slope of the line passing through (2, -8) and (-4, -8)

Answers

Answer:

Step-by-step explanation:

Given

(2, -8) → (x₁, y₁)(-4, -8) → (x₂, y₂)

Formula

Slope (m) = Δy/Δx = y₂ - y₁ / x₂ - x₁

Solving

m = -8 + 8 / -4 - 2m = 0
(2,-8)(-4,-8)

Slope:-

Adults can burn 210
calories per hour riding a
bike. If your bike ride was
21 hours, how many
calories would 8 adults
burn?

Answers

Answer:

210 x 21 = 4410 calories burned for 1 adult

4410 x 8 = 35280 calories burned for 8 adults

Step-by-step explanation:

First you figure out how much calories are burned total for 1 adult on a 21 hour bike ride with the information that you know of how much adults burn.

Next you multiply your answer by 8 to figure out the total of calories burned for all 8.

Step-by-step explanation:

35280 calories would be burnt.

I think it will help you.

210×21=4410

Now,

4410×8= 35280.

What is the function of a quadratic equation?

A quadratic function follows the condition: f(x) = ax² + bx + c. Here (a, b, and c) are real numbers and a ≠ 0.  

From the given information:

The function f(t) = -16t² +64t + 5 models the height of a ball

Where;

time (t) ⇒ secondsheight (h) ⇒ feet

The table given is as follows:

Time (in seconds)                 height, g(t) in feet

0                                             4

1                                              36

2                                              36

3                                              4

From the table, when t = 0, the function becomes:

f(t) = -16t² +64t + 5

f(t) = -16(0)² + 64(0) + 5

f(t) = 5

Therefore, we can conclude that the best statement that compares the ball is: f(t) is in the air for about 5 seconds, and the ball represented by g(t) is in the air for about 3 seconds.

Is B the expression for the perimeter of the rectangle, in inches?

Answers

Answer:

A, C, D

Step-by-step explanation:

P = 2L + 2W

L = 5W - 2

P = 2(5W - 2) + 2W

P = 10W - 4 + 2W

P = 12W - 4

Answer choices A, C, and D = 12W - 4

I hope this helps!

since w equal the width, the equation for the length is 5 times the width minus 2

that can be represented as 5w-2

the equation for perimeter is 2l+2w=p, where l is the length, w is the width, and p is the perimeter

so, plug in the equation we found into the length part of the perimeter equation and leave 2w the same

2(5w-2)+2w

that makes A correct

however, when you distribute the 2, the equation becomes 10w-4+2w

combine like terms to get 12w-4

that would make d also correct


in conclusion, a and d are the correct answers

hope that helps!!

Annabelle measured her bedroom as 11 ft times 13 ft, which is 143 square feet. she wants to change the units to square inches. which statements should she consider when converting? check all that apply. there are 12 inches in every foot. the length and width will change by a factor of 1.2 times 10 superscript 1. the length and width will change by a factor of 1.2 times 10 superscript 0. the area will change by a factor of (1.2 times 10 superscript 1 baseline) (1.2 times 10 superscript 1 baseline) = 1.44 times 10 superscript 2 baseline = 144, since area is length times width. the area will change by a factor of 2 (1.2 times 10 superscript 1 baseline) = (2 times 10 superscript 1 baseline) (1.2 times 10 superscript 1 baseline) = 2.4 times 10 superscript 2 baseline = 240, since both the length and width increase by that factor.

Answers

There are 12 inches in every foot and the area will be increased by 144 factors.

We know that the feet and inches are the units of length. One foot is 12 inches.

The length and the breadth are given as 11 feet and 13 feet.

The area of the bedroom is 143 square feet.

We know that 1ft = 12 in

So, The length would become 11 feet to 132 inches.

The breadth would become 13 feet to 156 inches.

What is the formula for the rectangle?

The area of the rectangle = length × Width

Therefore, the area of the rectangle = 132 ×  156

Since area of the rectangle= 20592 in .sq

The area of the bedroom increased by 144 factors.

By using properties for exponents, we will see that the equivalent expression is:

[tex]2x^{-4}y^6[/tex]

Which is the equivalent expression?

Here you need to remember the property:

[tex]a^n/a^m = a^{n - m}[/tex]

We have the expression:

[tex]\frac{-4x^{-3}y^4}{-2xy^{-2}}[/tex]

We can separate the fraction to:

[tex]\frac{-4x^{-3}y^4}{-2xy^{-2}} = \frac{-4}{-2}*\frac{x^{-3}}{x} *\frac{y^4}{y^{-2}}[/tex]

Now we can simplify by using the above relation, we will get:

[tex]\frac{-4x^{-3}y^4}{-2xy^{-2}} = \frac{-4}{-2}*\frac{x^{-3}}{x} *\frac{y^4}{y^{-2}} = 2*x^{-3-1}*y^{4 - (2)} = 2*x^{-4}*y^6[/tex]
