hours each day.
Step-by-step explanation:
The given function models the number of cars that are put through a quality control test each hour at a car production factory.
The given function is
We need to find the number of hours does the quality control facility operate each day.
Rewrite the given function it factored form.
Taking out the common factors from each parenthesis.
The factored form of given function is c(t)=-(t-10)(t+2).
Equate the function equal to 0 to find the x-intercept.
Number of hours cannot be negative. So from t=0 to t=10 quality control facility operate the cars.
Therefore the quality control facility operates for 10 hours each day.
The surface area of a sphere is:
A=4πr^2
And the circumference of a sphere (or circle) is:
C=2πr
Solving for r, r=C/(2π), and using that for r in the area equation gives you:
A=4π(C/(2π)^2
A=4π(C^2/(4π^2))
A=(4πC^2)/(4π^2)
A=(C^2)/π, since we are told that C=50 ft
A=2500/π ft^2
A≈795.8 ft^2 (to nearest tenth)
Answer: PR = 14
explanation: 11+3
Answer:
Step-by-step explanation:
We are given the two functions:
And we want to find:
This is equivalent to:
Then by substitution:
Evaluate:
Therefore:
Since you rolled 60 twos and 66 threes out of 360 times this experimental probability is (60+66)/360=126/360=0,35 which is c)
