Answer:
- 16
Step-by-step explanation:
Evaluate f(2) by substituting x = 2 into f(x) , that is
f(2) = 3(2) - 3 = 6 - 3 = 3
Evaluate g(- 1) by substituting x = - 1 into g(x) , that is
g(- 1) = 8 - (- 1)² = 8 - 1 = 7
Thus
4f(2) - 4g(- 1)
= 4(3) - 4(7)
= 12 - 28
= - 16
Lizards can eat 45 ants per minute. To find how many minutes it takes for lizards to eat 1,080 ants, you have to divide the total amount of ants by how many it can eat per minute.

Divide 1,080 by 45

It takes lizards <u>24 minutes</u> to eat 1,080 ants
Answer:
1.44 units²
Step-by-step explanation:
The angle for the big triangle is 60°, so the smaller triangle is 30°
so to find the base of the small triangle you can do tan 30 = X/2
so x is 2, which means that the base of the big triangle is 4.
The area of the big triangle is 1/2bh = 1/2(4)(2
) = 4
= 6.93
Find hypotenuse (radius) using Pythagorean Theorem r = 4
The area of the piece of pie is
= 8.37
8.37 - 6.93 = 1.44
