First we solve this equation:
x = cos^-1(0) = pi/2 and 3pi/2
Now, this is the answer for angles between 0 and 2pi
but there are "negative angles" and angles larger than 2pi
so the general solution that includes all of these cases is:
x = pi/2 + n*pi
here n is any integer.
Answer:
The correct answer would be A. 15/4.
Step-by-step explanation:
Slope is equal to the change in <em>y </em>over the change in x<em>, </em>or rise over run.
m = change in y/change in x
The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise).
m = y2 - y1/x2 - x1
Substitute in the values of x and y into the equation to find the slope.
m = 5 - (- 10)/- 1 - (- 5)
Simplify.
m = 15/4
Answer:
The box must be 2.4 in deep.
Step-by-step explanation:
Front dimensions are 9 in by 7.5 in. Find the area of the front: it is
A = (9 in)(7.5 in) = 67.5 in^2. One way to complete this work would be to divide the given volume by this area, 67.5 in^2.
A slightly different approach follows:
The volume must be 162 in^2. Given V = (width)(height)(depth),
V
(depth) must be -----------------------
(width)(height)
In this particular case,
162 in^3
(depth) must be ----------------------- = 2.4 in
(7.5 in)(9 in)
The box must be 2.4 in deep.
Answer:
The correct option is;
D. -2 ≤ y ≤ 4
Step-by-step explanation:
The range gives the limits for the possible outputs of a function for a given input. It defines the expected dependent variable output
The range of the graph is given by the values of the maximum and minimum values of y as follows;
The maximum value of y = 4
The minimum value of y = -2
Therefore, the range is -2 ≤ y ≤ 4
The Answer is -x Hope I helped! :D
