Answer:
A) R = 1900 -24t
B) 1684 billion barrels
C) 79.17 years
Step-by-step explanation:
<h3>A)</h3>
Reserves start at 1900 billion barrels and decrease by 24 billion barrels each year. The value for t=0 is 1900; the value for t=1 is 24 less.
R = 1900 -24t
__
<h3>B)</h3>
For t=9, the reserves will be ...
R = 1900 -24(9) = 1900 -216 = 1684 . . . . billion barrels
__
<h3>C)</h3>
The reserve will be 0 when ...
0 = 1900 -24t
24t = 1900 . . . . . add 24t
t ≈ 79.17 . . . . divide by 24
Reserves will be gone in about 79.17 years.
Pretty sure its B but if im wrong please dont be mad.

Step-by-step explanation:
im assuming this is a triangle
perimeter is 18+12+13=43
area is 12*13=156 then divide by 2 =78
G(x) is the same as saying y =
y = (2)⁻¹ When an exponent is negative it is the same as the inverse of it
y = 1/2¹
y = 1/2
--or--
g(2) = 1/2
