Answer:

f(3) = 7

Step-by-step explanation:

Using the recursive formula and f(1) = - 3 , then

f(2) = f(1) + 5 = - 3 + 5 = 2

f(3) = f(2) + 5 = 2 + 5 = 7

Akiko is making a pizza. The radius of the pizza is 19 inches. What is the circumference of the pizza (use 3.14 for pi and round

RideAnS [48]

Answer:

≈119.3

Step-by-step explanation:

The area for circumference is as follows:

$C = 2\pi r\\or\\C = d\pi$

The above equations mean the same thing, because the diameter is just 2 times the radius.

Anyhow, we insert this value into the equation...

$C = 2\pi(19)\\C = 38(3.14)\\C = 119.32\\$

This rounds to:

≈119.3

Help for the two questions shown, please!

Answer:

5) 140.8m^2 6) 360in^2

Step-by-step explanation:

6.4 x 6.4 = 40.96

(7.8 x 6.4) ÷ 2 = 24.96

24.96 x 4 = 99.84

99.84 + 40.96 = 140.8m^2

12 x 10 = 120in

13 x 10 = 130in

5 x 10 = 50in

(12 x 5) ÷ 2 = 30in

30 x 2 = 60in

60 + 50 + 130 + 120 = 360in^2
