Answer:

(-6, -5)

Step-by-step explanation:

Reflection across the y-axis leaves the point on the same horizontal line, but with the sign of its x-coordinate changed.

(x, y) ⇒ (-x, y) . . . . . reflection across the y-axis

(6, -5) ⇒ (-6, -5)

The image point is (-6, -5).

(12.5) (12.5) (12.5) (12.5)

(12) (12) (12) (12)

0.5 + 0.5 + 0.5 + 0.5 = 2 (0.5= 1/2 or 0.5 or 0.50)

more examples: (2/4) (3/6) (4/8) (5/10)

So you are gonna have four holes and two twelves

(12/12) (12/12) (12/12) (12/12) (2/12)

Write a polynomial function in standard form given the zeros. degree = 3; zeros = {-3, -2, 3}

Mariana [72]

Answer:

x^3 + 2x^2 - 9x - 18

Step-by-step explanation:

It is (x - 3)(x + 3)(x + 2)

= (x + 2)(x^2 - 9)

= x^3 - 9x + 2x^2 - 18

= x^3 + 2x^2 - 9x - 18 (Standard Form).

Which of the following is true about the right triangle?

katrin2010 [14]

Option 1. $cos (a) = \frac{3}{5}$ , option 3. $sin (a) = \frac{4}{5}$ , and option 5. $tan (a) = \frac{4}{3}$ are true about the right triangle.

Step-by-step explanation:

Step 1:

According to the Pythagorean theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

Here the hypotenuse measures 15 units. Assume the other side measures x.

$15^{2} = x^{2} +9^{2} , x^{2} = 15^{2} -9^{2} .$

$x^{2} = 144, x= 12.$

Step 2:

$sin \theta = \frac{oppositeside}{hypotenuse} ,cos \theta = \frac{adjacentside}{hypotenuse} , tan \theta = \frac{oppositeside}{adjacentside}.$

For angle A, the opposite side is 12 units long, the adjacent side is 9 units long and the hypotenuse is 15 units long.

$sin (a) = \frac{12}{15} ,cos(a) = \frac{9}{15} , tan(a) = \frac{12}{9}.$

$sin (a) = \frac{4}{5} ,cos (a) = \frac{3}{5} , tan (a) = \frac{4}{3}.$

So option 1. $cos (a) = \frac{3}{5}$ , option 3. $sin (a) = \frac{4}{5}$ , and option 5. $tan (a) = \frac{4}{3}$ are true about the right triangle.

Zach bought two new jet skis for $15,480. He will make 36 equal payments. How much will each payment be?

telo118 [61]

36x = 15480

x = 15480/36

x = 5160/12

x = 2580/6

x = 860/2

x = 430

Zach made equal payments of $430
