Answer:
h α t
h = kt
k = h/t
350 = k5
350/5 = k
k = 70
Step-by-step explanation:
Given that :
Ballon height varies directly as the Ascent time in minutes
Height of hot air Ballon rises 350 feets in 5 seconds
Expressing as a direct variation :
Let height of Ballon = h
Time it takes to rise = t
h α t
h = kt
k = h/t
350 = k5
350/5 = k
k = 70
Answer:
0.6875
Step-by-step explanation:
24.5 = 3.2⁴ˣ
To get the exponent out of its exponent form, we need to take the ln of both sides:
ln(24.5) = 4x · ln(3.2) - divide both sides by ln(3.2)
= 4x - divide both sides by 4
x = 0.6875
Answer:
The value of the car will be 6100 dollars in 8.8 years
