Answer:
one x-intercept.
Transformation: shift to the right 8 units.
Step-by-step explanation:
The parent function is 
To find the number of x-intercepts, we equate the function to zero.
There is only one x-intercept at t=0.
The transformed function is
This function is obtained shifting the parent function 8 units to the right.
The x-intercept will now be at t=8.
Hence the image function also has one x-intercept.
Answer:12
Step-by-step explanation:
a = 56
given 28 = 
a
multiply both sides by 2 to eliminate the fraction
56 = a
As a check
× 56 = 28 ← True
Imagine the path of the tip of the pendulum as an arc of a circle. The circle would have a radius of 4 feet and the arc would be 20 degrees. To calculate the length of the arc, you need to find 20 degrees of the circumference.
Length of Arc = 2*pi*R*Degree of arc/360
Length of Arc = 2*pi*4*20/360
Length of Arc = 8pi * 1/18
Length of Arc = 4/9 pi feet
<span>Length of Arc ~ 1.396263402 feet

For this case we have the following expression:
By definition, a coefficient is the term that accompanies one or more variables.
For example:
The coefficient of the linear term is 3.
So, in the given expression we have to:
-4 is the term that accompanies the variables xy.
Answer:
-4
