Answer:
The scale factor of the dilation is 3
Step-by-step explanation:
we know that
A dilation is a non rigid transformation that produce similar figures
so
Rectangle ABCD and rectangle A'B'C'D' are similar
Remember that
If two figures are similar, then the ratio of its corresponding sides is proportional
Let
z ----> the scale factor
we have
----> difference of x-coordinates
---> difference of x-coordinates
substitute
The scale factor is greater than 1
so
The dilation is a enlargement
Remember this: for a trig function of <span>y = A sin(Bx + C) + D
</span><span><span>amplitude is A
</span><span>period is <span>2π/B
</span></span><span>phase shift is −C/B
</span><span>vertical shift is <span>D
So the amplitude is -4, the period is </span></span></span>π and the phase shift is -3.14/2 = 1.57.
Answer:
x = 3
Step-by-step explanation:
8 - 2x = 2
- 2x = 2 - 8
- 2x = - 6
- x = - 6/2
- x = - 3
x = 3
