Answer:
A.
Step-by-step explanation:
81 - 16 = 65
81 - 16 = 65
formula c^2 = a^2 - b^2
c^2 = 81 - 16
√c^2 = √ 65
c = √ 65
Answer:
g(x)=-3x
Step-by-step explanation:
Reflecting any equation over the y-axis will make it negative, hence 3x->-3x
Add like terms to get -4c = 3. divide by ,-4 each side so c = -3/4
Answer:
24416.64
Step-by-step explanation:
Based on the standard formula,4/3×π×r^3
The π has been given already and r=18
4/3×3.14×18^3
V=24416.64
Answer:
a) The car will be worth $8000 after 2.9 years.
b) The car will be worth $6000 after 4.2 years.
c) The car will be worth $1000 after 12.7 years.
Step-by-step explanation:
The value of the car after t years is given by:

According to the model, when will the car be worth V(t)?
We have to find t for the given value of V(t). So





(a) $8000
V(t) = 8000

The car will be worth $8000 after 2.9 years.
(b) $6000
V(t) = 6000

The car will be worth $6000 after 4.2 years.
(c) $1000
V(t) = 1000

The car will be worth $1000 after 12.7 years.
