In the right triangle shown,
∠
a
=
3
0
∘
∠a=30
∘
angle, a, equals, 30, degrees and
a
b
=
12
3
ab=12
3

a, b, equals, 12, square root of, 3, end square root.

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right

$450 i think. hope this ☺

soo this can be solve by using the formula:

f = p( 1 + i)^ n

where f is the future profit

p is the initial profit

i is the percent increase

n is the number of years

a . f = 30000 ( 1.05)^n

b. f = 30000 ( 1.05)^15

f = $62,368
