The decay factor here is 0.85, and it means the car’s value changes by 85% every year, or goes down by 15% every year.
The formula for exponential decay is y = a(1 - b)^x
y is the final amount.
a is the initial amount, which is $30,000 in this case.
(1 - b) is the decay factor, or the number the original value gets multiplied by each year, which is 0.85 here.
b is the percent decrease in decimal form. In this case, we can find it using the formula (1 - b) = 0.85. We soon find that b = 0.15, or 15%.
x is the number of years.
Answer:
A = 40x + 175
B = 50x + 125
5 hours
Step-by-step explanation:
The equations are as follows:
According to the question
Let us assume the number of hours be x
For company A
40x + 175
For company B
50x + 125
Now equate these two equations
40x + 175 = 50x + 125
175 - 125 = 10x
x = 5
Hence, the number of hours is 5
Volume (tank)=base x heitht
base is a squeare, so base=side²
Volume(Tank)=side² * height
600 m³=side² * 6 m
side²=600 m³/ 6 m
side²=100 m²
side=√(100 m²)=10 m.
answer: the side of the base is 10 m.
281.9 is the answer, but rounded it would be about 282
hope this helps, im not 100% sure

Answer:
h ≤ 6 2/3
Step-by-step explanation:
The inequality is presumed to be ...
15h +40 ≤ 140
15h ≤ 100
h ≤ 6 2/3
__
The graph shows h ≥ 0, because the inequality is only reasonable for h ≥ 0.
