7. Which statement is true for any two circles? a. The ratio of the areas of the circles is the same as the ratio of their radii.
b. The ratio of the circumference of the circles is the same as the ratio of their radii.
c. The ratio of the areas of the circles is the same as the ratio of their diameters.
d. The ratio of the areas of the circles is the same as the ratio of their circumference.

range is infinite on both x and y axis positive and negative

step-by-step explanation:

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2
