Answer:
ANSWER:
An exponential growth function has constant doubling time.
Step-by-step explanation:
EXPLANATION:
The formula for calculating exponential growth is
A=A'e^kt
here:
A=amount after growth
A'=initial value
e=2.718
k=continuous growth rate
t=time passed
8.25 hours is our base number here. 1/3 of it is taken up when he stops at the gas station.
8.25, 4.125 is half of it, 2.75 is our answer for this,
8.25/3 gives you 2.75 due to 2.75 making it 5.5 when doubled and so on
so, the answer is 2 3/4 hours, D
Answer:
(4, - 7)
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
f(x) = (x - 4)² - 7 ← is in vertex form
with (h, k) = (4, - 7 ) ← vertex
Answer:
62° and 96°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 remote interior angles.
Let x be the other remote interior angle, then
22 + x = 84 ( subtract 22 from both sides )
x = 62
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 known angles from 180 for third angle
third angle = 180 - (62 + 22) = 180 - 84 = 96
The other 2 interior angles are 62° and 96°
Enrollment at X = 0 is at 20.
Enrollment at X = 8 is 120.
Find the difference between those values:
120 - 20 = 100
Divide that difference by the difference in the x values:
100 /8 = 12.5
The answer is D. 12.5
