Problem Page Ann will run more than 38 miles this week. So far, she has run 21 miles. What are the possible numbers of additiona

krok68 [10]

She has run 21 miles already. Let t be the number of additional miles added on.

In total, she has run t+21 miles

This is going to be set greater than 38 since "Ann will run more than 38 miles"

So we have this inequality

t+21 > 38

we solve for t by subtracting 21 from both sides

t+21 > 38
t+21-21 > 38-21
t+0 > 17
t > 17

The final answer is t > 17

which means that the possible additional number of miles she could run is anything larger than 17. So t = 18 is one possibility.

As θ increases, the value of cos θ increase, decreases or stays the same?

icang [17]

Answer:

As θ increases, the value of cos θ decreases

Step-by-step explanation:

As as θ increases, the value of cos θ decreases from 1 to -1 in the first two quadrants ( between 0 and 180 degrees). Cos(0) = 1, cos(90) = 0, cos(180) = -1.

On the other hand, as θ increases from 180 to 360 degrees (last two quadrants) the value of cos θ increases from -1 to 1.
