√5 percent of 5√5 = a. 0.05 b. 0.25 c. 0.5 d. 2.5 e. 25

Stels [109]

$\sqrt{5} \% \times 5\sqrt{5}=\frac{\sqrt{5}}{100} \times 5\sqrt{5}=\frac{5 \times \sqrt{25}}{100}=\frac{5 \times 5}{100}=\frac{25}{100}=0.25$

The answer is B. 0.25.

Passes through (1,12) and has a vertex (10,-4)

agasfer [191]

Answer: 16/81 (x-10)^2 -4

Step-by-step explanation:

To write a vertex equation with just a point and the vertex, you have to figure out the variables.

In vertex form, the equation is y = a (x-h)^2 + k

Your y is 12, x = 1, h = 10, and k = -4

Plug everything into equation

12 = a (1 - 10)^2 -4

12 = a (-9)^2 - 4

12 = 81a - 4

16 = 81a

16/81 = a

Now you know what the 'a' value is.

If you graph 16/81 (x-10)^2 -4 , you will get a point at (1,12) and a vertex of (10,-4)!

I hope this helps!

SOMEONE PLZ HELP ME WITH 10 and 8!!!!!

Allisa [31]

Answer:

10. $23.75^{o}$

8. $34.76^{o}$

Step-by-step explanation:

10. each step is 36, so i added it twice to get 72.

then add 16 twice = 32

this gives us two sides to our triangle.

We can now use tan since we know opp and adj

tan 32/72 = .44

arctan = 23.75

8. since we again know the opposite and adjacent sides to the angle e are trying to find we can use tan again.

tan 12.5/18 = .694

arctan= 34.76
