Answer:
f(x) = 3^x increases steadily on the interval [4,5].
Step-by-step explanation:
This exponential function f(x) = 3^x has a positive base (3) which is larger than 1. Thus, this function continues to increase as x increases, including the case where x increases from 4 to 5.
Remember that all the interior angles of a triangle add up to 180°.
The picture tells us two of the angles,

which is 40° and

which is also 40°.
Subtract the measurement of these two angles from 180° to find the measure of the third angle,

:
180° - 40° - 40° = 100°.
The measure of angle RST is 100°.

Q3.
If ΔGHI and ΔJKL are similar, then the sides are in proportion:

We have
JL = x, GI = 9 ft, LK = 24 ft, IH = 12 ft.
Substitute:

<em> multiply both sides by 2</em>

Q4.
We must multiply the original length by a scale factor of 3/4:

Verbal model: mile/inch=mile/inch
Proportion: 7/8÷3/10=x/1
Solve= 7/8*10/3=x/1
70/24=x/1
70=24x
x=35/12
The unit rate must be
