This is a difference of squares. Every time you have the difference between two squares, you can factor it as the product between the sum and the difference of the roots:

a^2-b^2 = (a+b)(a-b)

In your case, the squares are

y^2 \to \text{the square of } y

16 \to \text{the square of } 4

So, the difference between the squares, y^2-16 can be written as the multiplication between the sum and difference of the roots:

y^2-16=(y+4)(y-4)

Find the area of the parallelogram shown below.60 squ
ArbitrLikvidat [17]

Answer:

A

Step-by-step explanation:

The area for a parallelogram is given by the formula:

A=bh

Where b is the base length and h is the vertical height.

The base length is 6 and the height is 10 (if you flip the figure 90 degrees). So:

A=6(10)

Multiply:

A=60\text{ units}^2

Our answer is A.

And we're done!

Is the value of sine positive, negative, or zero at 3π/2?
Gnom [1K]

Answer:

<h2>Negative.</h2>

Step-by-step explanation:

The given function is

sin(\frac{3 \pi}{2} )

Where \pi = 180 \°, so the angle is \frac{3(180)}{2}=270

This angle is at between the third and fourth quadrant, the angle has its endside at y-axis, specifically, at its negative side, where the sin function is -1, because it's in the negative part of y-axis.

Therefore, the right answer is negative.
