The vertex of this parabola is at (-4,-1). When the y-value is 0, the xvalue is 2
yaroslaw [1]
The standard form for this parabola is x = a(y-k)^2 + h because this is a sideways-opening parabola. Our h and k values for the vertex are (-4, -1). And it goes through (2,0). We just need to solve for the a. Filling in accordingly, 2 = a(0+1)^2-4 so 2 = a - 4. a = 6. A above.

correct answer is 6!

What are the ratios for SIN A and COS A
miskamm [114]

Answer:

A

Step-by-step explanation:

A good trick for trigonometric functions is to remember SOHCAHTOA:

Sin=<u>O</u>pposite over <u>H</u>ypotenuse

Cos=<u>A</u>djacent over <u>H</u>ypotenuse

Tan=<u>O</u>pposite over <u>A</u>djacent

The red arrows on the attachment indicate where opposite, hypotenuse, and adjacent are for angle A.

So in this case, the sin of angle A (opposite over hypotenuse) would be \frac{24}{26} and cos A (adjacent over hypotenuse) would be \frac{10}{26}.

I hope this helps!
