Answer:
Step-by-step explanation:
Function 'f' represents the number of miles (y-values) covered by the helicopter in 'x' (x-values) minutes.
f(x) = 40 - 2x
For x = 0,
f(x) = 40 miles
For f(x) = 0,
0 = 40 - 2x
x = 20 minutes
This shows that helicopter traveled 40 miles in 20 minutes.
Similarly, given graph shows distance covered by the jet on y-axis and duration of flight on x-axis.
For x = 0,
f(x) = 500 miles
For f(x) = 0,
x = 100 minutes
Commercial jet traveled 500 miles in 100 minutes.
Answer:
18.68 feet
Step-by-step explanation:
- Just did the quiz
- Also plugged it into a calculator I found online
Your calculator probably only evaluates in base 10 (ln is base e but we won't use that today)
so
where c is the new base
so if you wanted in base 10
using calculator, that is about 2.16096
We know that
[surface area of the cone]=pi*r²+pi*r*l
where
r is the radius
l is the slant height
l²=h²+r²
h=43 m
r=14/2---> 7 m
l²=43²+7²----> l²=1898--------> l=43.57 m
[surface area of the cone]=pi*7²+pi*7*43.57----> 1111.53 m²----> 1112 m²
the answer is the option
<span>B. 1,112 square meters</span>
The area of the cross section of the column is 81π
<h3>What is the area of the cross section of the column?</h3>
The given parameters are
Circumference, C = π18 meters
The area of the cross section of the column is calculated using the following circle formula
A = π(C/2π)^2
Substitute C = π18 in A = π(C/2π)^2
A = π(π18/2π)^2
Evaluate the quotient
A = π(9)^2
This gives
A = 81π
Hence, the area of the cross section of the column is 81π
