Answer:

2/3

Step-by-step explanation:

Time it would take Sarah to complete the work in one hour = work completed in 1/4 hours x 4

We are multiplying by 4 because there are 4, 1/4 in an hour

1/4 + 1/4 + 1/4 + 1/4 = 1 hour

\frac{1}{6} × 4 = \frac{4}{6}

To transform to the simplest form. divide both the numerator and the denominator by 2

= \frac{2}{3}

What is the shape of the graph of the function?<br> h(t) = 0.32 - 0.5t
allsm [11]

Answer:

Answer (a) is correct

Step-by-step explanation:

This is not the same function that was given to you in the problem.

As you have typed it, this function is linear.  The one in the homework problem is exponential.

We will ignore the linear function h(t) = 0.32 - 0.5t.

We will focus on h(t) = 0.32 - 0.5^t.

If t = 0, then 0.5^t = 0.5 ^0 = 1, and so h(0) = 0.32 - 1 = -0.68  =>  (0, -0.68)

Continuing with a few other t values chosen at random:

h(1) = -0.18

h(2) = 0.07

Notice that h is increasing as x increases!

h(4) = 0.2575

and so on.

answer A is the correct one.

h(1) = 0.32 - 0.5^1 = 0.32 - 0.5 = -0.18

Find an equation, in slope-intercept form, that passes through point (-3, -7) with slope -3.
Thepotemich [5.8K]
Slope-intercept form is y = mx + b, and m is the slope
Because the slope is -3, m = -3
y = -3x + b

Plug in the point and solve for b
-7 = -3(-3) + b
-7 = 9 + b
-16 = b

a. y = -3x -16
