The correct answer is Choice B. The graph is symmetrical about the y-axis.

The quadratic parent function is a parabola. It is shaped like the letter U. Therefore, you could draw a vertical line (y-axis) down the middle and it would be symmetrical.

The correct answer is B) its graph is symmetrical about the y-axis.

It is not symmetrical about the x-axis; you cannot "fold" the graph across the x-axis.
Its domain is not the set of non-negative numbers; you can use negative numbers for x as well as positive.
Its range is not the set of all real numbers; we cannot get a negative y-value from squaring a number.

Factor completly x^2 -64

∑ Hey, jillianwagler ⊃

Answer:

$\left(x+8\right)\left(x-8\right)$

Step-by-step explanation:

⇒ Given info:

Factor completely $x^2 -64$

⇒ Solution:

Rewrite 64 as 8 ² because 8² is equal to 64. 8 ² = 8 × 8 = 64.

$=x^2-8^2$

Applying difference of two squares formula: $x^2-y^2=\left(x+y\right)\left(x-y\right)$

$=x^2-8^2=\left(x+8\right)\left(x-8\right)\\$

$=\left(x+8\right)\left(x-8\right)$

Answer~: $\left(x+8\right)\left(x-8\right)$

If a 45 45 90 triangle has the hypothenuse of 10 what would the legs x and y be

melamori03 [73]

Answer:

Step-by-step explanation:

When working with 45-45-90 triangles the hypotenuse is the same as the other legs multiplied by root 2. Therefore if you need to find the legs and already have the hypotenuse, divide the hypotenuse by root 2.

10/ sqrt(2) = 7.1 is the rounded answer.

to double check your work just multiply 7.1 by the square root of 2 and you'll get close to 10. (because the answer is rounded and not exact.)
