Answer:
11.19ft * 15.19ft
Step-by-step explanation:
Width = x
Length = x-4
Area = 170ft2
Area of a rectangle = Length * Width
170ft^2 = (x-4) * x
x(x-4) = 170...........equation(1)
x^2-4x-170 = 0......equation(2)
Using the quadratic equation(for equation 2),
-b+-sqrtb^2-4ac/2a
from equation(2): a=1x=1
b= -4
c= -170
thus, x= 4 + sq.rt696/2 = 4 +26.38 =30.38/2=15.19
Answer:
Step-by-step explanation:
5/8
Answer:
4π
Step-by-step explanation:
This is a sinusoidal function.
The period of the function is basically the length from one wave crest to the next crest. We can take any 2 subsequent crests.
Lets take our first crest to be at 3π
The next one will be at 7π, as we can see
So, the length from one crest to the next is the period, which is:
7π - 3π
= 4π
Third answer choice is right, 4π is the period.
The ratio of students to teachers, is B, 8/1.
This is because if there are 24 students and 3 teachers, and you need to know the amount of students there would be per teacher, you divide both given numbers by 3.
24 divided by 3 is 8 (representing students)
and 3 divided by 3 is 1 (representing teachers)
Thus, the answer is 8/1
The midpoint is (-2, -6). You need to find the mean of x coordinate and the y coordinate.
