cos(x)tan(x)

Transform the expression by using the formula for tan theta:
tan(t)= sin(t)/cos(t)

cos(x)= sin(x)/cos(x)

Cancel out the cos(x) since it’s on both sides

Final answer : sin(x)

cos(x)tan(x) is equal to sin(x)

A rectangle has an area of 2x2 - 19x +45 ft? What are the dimensions of the rectangle? (hint: factor)​

Answers

I think the answer is (2x - 9)(x - 5)

The dimensions of the rectangle will be (2x - 9)(x - 5).

What is a quadratic equation?

A quadratic equation is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.

Given that the area of the rectangle is represented by a quadratic equation 2x² - 19x +45.

The dimensions of the rectangle will be the factors of the quadratic equation.

2x² - 19x + 45

2x² - 10x -9x + 45= 0

2x( x - 5 )-9(x - 5)= 0

( 2x - 9 ) ( x - 5 ) = 0

Therefore, the dimensions of the rectangle will be (2x - 9)(x - 5).

✨✨Answer number 7please ✨✨

Answers

Answer: A

Step-by-step explanation: This is a rotation. An easy way to tell the difference between a rotation and a reflection is that the order of the points will not change in a rotation. For this problem, pre-image ABCD is still in the order of ABCD when mapped to the image. (You can still follow along the points in that order). When something is reflected, the points swap orders and you would not be able to follow the points in order.

Now that we know this is a rotation, Notice A’ B’ C’ and D’ are all left of the pre-image. This means the mapped image moves counter clockwise.
