Step-by-step explanation:
The amplitude of the function is half the difference between the maximum and minimum:
A = (8 -(-4))/2 = 6
The multiplier of t is (2π)/period, so is ...
B = (2π)/12 = π/6
The vertical offset is the average of the minimum and the maximum:
D = (8 +(-4))/2 = 2
The peak is at t=0, so the cosine function is the appropriate choice.
__
Then the function is ...
f(t) = Acos(Bt) +D
f(t) = 6cos(πt/6) +2
Answer:
D
Hey There!
To find the answer you have to add the frequencies of all of them and take the frequency of 3 people being in a car and divide that by the sum of all of the frequencies if that makes sense
37+98+40+25=200
The frequency of 3 people being in a car is 40
so we would do
which is equal to
Therefore D is your answer
Answer and explanation:
To find : Calculate to the nearest 1/10th meter the length of the side of a 7th, 12th, and 30th hectare square plot.
Solution :
The area of the square is given by,
where s is the side length.
We know,
1) The area of square plot is 7 hectare.
Area in meter square is
Substitute the value in the formula,
Side nearest to 1/10th meter is 264.8 meter.
2) The area of square plot is 12 hectare.
Area in meter square is
Substitute the value in the formula,
Side nearest to 1/10th meter is 346.4 meter.
3) The area of square plot is 30 hectare.
Area in meter square is
Substitute the value in the formula,
Side nearest to 1/10th meter is 547.7 meter.
