Answer:

False

Step-by-step explanation:

The given equation is:

2sin^2x-sinx-1

Substituting x=\frac{3\pi}{2} in the above given equation, we have

=2sin(\frac{3\pi}{2})^2-sin(\frac{3\pi}{2})-1

=2(-1)^2-(-1)-1

=2+1-1

=2

Thus, the value of the given equation by substituting the value of x is equal to 2 and not zero, therefore the given statement is false.

Find the perimeter and area of the image after dilating the figure shown with the given scale factor.
Alika [10]

Answer:

P = 96

A = 575

Step-by-step explanation:

basically dialating a figure is making it smaller or larger by a certain amount and in this case it is 6 so you have to make each side of your square 6 times larger so each side would be 24 (of whatever unit you are using) so then you would calculate it by doing 24*24 to find the area and 24*4 to find the perimeter.
