C(t)=26t^2+168t+4208, and we wish to know when C(t)=15000
26t^2+168t+4208=15000
26t^2+168t-10792=0
They want you to use the quadratic formula...
For a quadratic of the form ax^2+bx+c=0, the quadratic formula is:
x=(-b±√(b^2-4ac))/(2a), in this case we have:
x=(-168±√1122368)/52, since x>0
x≈17.14
1958+17.14≈1975.14
So by 1976 the number of new cars will reach 15000.

Answer:
$25.58 total dollars
Step-by-step explanation:
add 5.50 + 10.75 which equals 16.25 then add 9.33 on to 16.25 and you should get your answer.
To determine the expected total value of the investment after 20 years, we simply plug in the given to the prepared equation,
A = P x (1.12^n)
Substituting the known values,
A = ($5000) x (1.12^20)
A = $48,231.47
Thus, the expected amount of your purchase is $48,231.47.
I just multiplied the both radius by each other. And that's 2cm × 4cm= 8cm
