<u>Answer:</u> 40
<u>Reasoning:</u> 34/.85= 40
40x.85=34
a_3 is 45 and a_10 is 98415
Step-by-step explanation:
Given
a_1 = 5
a_2 = 15
First of all we have to calculate the common ratio of the sequence. The common ratio is the ratio between two consecutive terms of a geometric sequence.
So,

The explicit formula for geometric sequence is:

Putting the value of r and a_1

Putting n=3 in the explicit formula

Putting n=10 for tenth term

Hence,
a_3 is 45 and a_10 is 98415

.48 is equal to 48/100=12/25 so
28 12/25
Area = width * height
since the window is 20 inches higher than the width:
width +20 = height
640 = width * width+20
640 = width^2 +20*width
width^2 +20*width - 640 = 0
width = 17.203
**********************************************************
Double Check
if width = 17.203 then height = 37.203
area = 17.203 * 37.203 = 640 square inches Correct!!
Answer S−2BP=h
Explanation:isolate the Phterm on one side of the equation:S−2B=PhDivide both sides by P:S−2BP=h
