Answer:
g(x)= 9 cos (x -
) +7
Step-by-step explanation:
What is given is f(x) = g cos (x - pi/2) + 3
Note that the standard form of cosine function is a cos (bx + c) + d
a= amplitude
-c/b = phase shift
d = vertical shift
After moving pi/6 to the left --
x = pi/2 - pi/6 = pi/3
once moving pi/6 left, it is at pi/3
moving 4 units up just means adding 4 + 3, and that equals 7, that would be the vertical shift once applied.
So the equation that represents g(x) is C. 9 cos (x - pi/3) + 7
The absolute value equation that can be used to find the minimum and maximum radius accepted is:
A. |r - 1.25| = 0.1.
<h3>What is the absolute value?</h3>
The absolute value function is defined as follows:


It measures the distance of a point x to the origin.
In this problem, the absolute value of the difference between the radius and 1.25 cm must be of 0.1 to find the thresholds, hence the equation is:
A. |r - 1.25| = 0.1.

You can solve for x and y in terms of z, then let z take on the value of the parameter.
Subtracting the first equation from the second, you get
... x_2 +x_3 = 1
Subtracting that from the first equation gives you
... x_1 +2x_3 = 3
Let x_3 = t. Then your parametric equations are ...
