Answer:
9
Step-by-step explanation:
First off you need to find the interval that four falls in.
Four is not less than three so you can rule out the first one, four is not greater than 10 so you can rule out the last one. But four is greater than three and less than ten, so it falls in the second interval.
So, now you can substitute four in for x for the second equation
4^2-7
16-7
=9
Answer:
x = 70.53 degrees

⇒ cos-1 x = 
⇒ cos-1 x = 0.33
⇒ x = 70.528
round to the nearest tenth:
⇒ 70.53
The answer is 586.17 cm^2
12x2=24
The middle is extra. All you need to answer is the $12 is half his allowence left.
