Emily is 280 miles away from home. She is traveling back at a rate of 40 miles per hour. Determine which graphs and which equation represents Emily’s distance from home, D, after Emily travels h hours.

Answers

The required equation for the distance is y = 280 - 40h and graph is shown below.

What is speed?

In unit time, the distance covered by any object is called speed.

In mathematical term, Speed is express as S = D/T,

where S=speed, D=distance, T= time.

Given that,

Distance of Emily from her home = 280 miles,

The speed of Emily of coming back = 40 miles per hour.

In h hours, the distance covered by Emily = 40h

Let the remaining distance is y,

So the equation can be written as,

y = 280 - 40h.

The graph of the equation represented below.

Answer:

-40*h+280

Step-by-step explanation:

Let s define the function f which represents Emily's distance from home

at h = 0 Emily is 280 miles away from home

so f(0)=280

as she is traveling back at a rate of 40 miles per hour

f(h)=-40*h+280

x^2 - x - 30 =

2m^2 - 2m - 60 =

Answers

Looking at x^2 - x - 30, we see that 5*6=30, so we can immediately conclude that x^2 - x - 30 = (x+5)(x-6).  check this by multiplication.

2m^2 - 2m - 60 can be reduced to 2(m^2 - m - 30), which in turn can be factored as    2(m+5)(m-6).  The trick here is to notice how easily "2" can be factored out of the given equation.

∠A and ∠B are complementary angles of right triangle ABC, cos A = 0.83, and cos B = 0.55. What is sin A sin B?

Answers

Complementary angles are two angles which add up to 90° or forms a right angle. First, we find the value of A and B.

A = arccosine (0.83) = 34°
B = 90 - 34 = 56°

Thus, sin A = 0.56 and sin B = 0.83.

Is -7+9=-9+7 true,false,or open?
