Answer:
A : it cannot be modeled with a rectangle
Step-by-step explanation:
edge 2020 . good luck !
This function can be represented by the quadratic equation f(x)=0.15(x+60)^2
This situation can be represented by the exponential function f(x)=60 x 1.15^x
This function has no x-intercept
After 4 years the value of the investment will be $120.00
After 6 years the value of the investment will be $653.00
After 7.86 years the value of the investment will be 3 times the initial value
After 8 years the value of the investment will be $184.00
Answer: The function can be represented by the exponential function :
This function has no x-intercept .
After 7.86 years the value of the investment will be 3 times the initial value .
After 8 years the value of the investment will be $184.00.
Step-by-step explanation:
The exponential growth function is given by :-
, where A is the initial value , r is the rate of growth and x is the time period.
Given: A = $60
r=15%=0.15
Now, the function can be represented by the exponential function :
We know that exponential function has no intercept , thus this function has no intercept.
∴
Now, at x=4
Now, at x=6
Now, at x=7.86
∴ After 7.86 years the value of the investment will be 3 times the initial value
Now, at x=8
Answer:
It takes 3 seconds over the interval [0,3]
Step-by-step explanation:
To find when the roller coaster reaches the ground, find when d=0.
To solve divide each term by 16 and factor:
Solve for t by setting each factor to 0.
t-3=0 so t=3
t+3=0 so t=-3
This means the car is in the air from 0 to 3 second.
The time interval will be 0<t<3 or (0, 3)
A interval is a set of real numbers that contains all real numbers lying between any two numbers of the set.
Given:
d = 144 – 16t²
Now,
d>0
144 – 16t²>0
144>16t²
144/16>t²
9>t²
t<±3
Since, timecan't be negative.
So, t<3
Hence, the interval for which Greg’s car moving in the air is, 0<t<3 or (0, 3).
