The rate of change is -6c per hour.

42c/7=6.

I believe the rate of change is negative because the question states that the temperature is decreasing.

A constant function is characterized by having the same value for f(x) in all it's domain. This means every value of x will have the same value in the axis y. You can see that in the graphic as a horizontal line.

Please help! The answer isn’t 36! <br> Find the value of the expression:
Brums [2.3K]

Answer:

3.6

Step-by-step explanation:

Hi there!

We are given this expression:

.6√36 (.6*√36)

And we want to find the value of it

.6 can be re-written as 0.6

In that case,

0.6*√36

First, simplify what's under the radical: √36, which is equal to 6 (6*6=36)

The expression then becomes:

0.6*6

Multiply those numbers together

0.6*6=<u>3.6</u>

Hope this helps!

The height of the flag pole is 51 ft.

Solution:

Paul creates the smaller triangle and flag pole creates the larger triangle.

Base of smaller triangle = 10 ft

Height of smaller triangle = 6 ft

Base of the larger triangle = 85 ft

Let the height of the flagpole be h.

$\Rightarrow \frac{6}{10} =\frac{h}{85}

Multiply by 85 on both sides.

$\Rightarrow 85 \times \frac{6}{10} =\frac{h}{85}  \times85

$\Rightarrow \frac{510}{10} =h

⇒ 51 = h

The height of the flag pole is 51 ft.
