Answer:
Step-by-step explanation:
a). By the rotation of 90° clockwise around the origin image ΔE'F'G' will be in 2nd quadrant while Destiny has plotted in fourth quadrant.
b). Rule to find the coordinates of the image will be,
(x, y) → (y, -x)
E(-5, -1) → E'(-1, 5)
F(-2, -3) → F'(-3, 2)
G(-4, -4) → G'(-4, 4)
c). Now we can plot these points on the graph as shown in the attached picture.
This is an example of a
sine wave function. A given sine wave function has a standard form of:
y = A sin [B (x + C)] + D
Where,
A = absolute value of
amplitude
2 π / B = the period of
the sine wave
D = is the midline of y
C = phase of the sine
wave
Rewriting the given
equation into this form will yield:
f (x) = -7 sin[4 (x – π / 4)]
+ 2
Therefore from this form,
we can get the answers:
Amplitude = 7
Period = 2π / 4 = π / 2

Answer:
$6938.78
Step-by-step explanation:
Interest = Principal x Rate x Time (in years)
let 'P' = Principal
85 = P × .021 × 
85 = .01225P
85 / .01225 = P
6938.78 = P
Answer:
There are 14 more science fiction books than mystery books
Step-by-step explanation:
Multiply 13 x 7 = 91
Multiply 15 x 7 = 105
Subtract 105 - 91 = 14
We are asked to describe into one term the definition "procedure for selecting sample elements from a total set of observations." The answer is sampling method. Sampling method is a method used by researchers to evaluate a large size of correspondents or samples such that the representive sample is still considered.
