Answer:
B. x = 2.77
Step-by-step explanation:
3^x = 21
You first look for a base for 21 that is 3 to the power of something.
21 = 3^2.77
So 3^x = 2^2.77
They have the same base so
x= 2.77
Y=1x because if you draw it on the line you’ll see the linear variation
General Idea:
We can use the below formula to find the area of sector (A), when angle of sector and radius is given:

Applying the concept:
We need to substitute 84 for
and 160 for A in the above formula:

Conclusion:
If a windshield wiper covers an area of approximately 160 square inches when it rotates at an angle of 84°, the length of the wiper to the nearest tenth of an inch is <u>14.8</u>
Answer:
FG = 28
Step-by-step explanation:
You are given the ratio 1:2. That means that the photocopied monorail is twice as big as the original. All you need to do is multiply 14 by 2 to get your answer.
