Answer: side c is 20!

Step-by-step explanation:

So since this a right-angled triangle, you might want to use the Pythagorean Theorem. First, use the formula A(squared) + B(squared) + C(squared). Since c is unknown just put that as x(squared). Then, answer A(squared) and B(squared which would be 16mm and 12mm in this case. Multiply 16*16.... and you get 256. Then do the same to side B which is 12 and you get 144. Then know you can add them both together and get 400. What is the square root of 400? Yes, it’s 20. And there is you answer!

the vertex of this parabola is (2,-1). When the x-value is 5 the y-value is 0.what is the coefficient of the squared expression
weeeeeb [17]
1/9
Here's the proper explanation:
Since the vertex is (2,-1), the original equation will look like this: y=a*(x-2)^2-1
When the substitution happens we get to this:
0=a*(5-2)^2-1 then 1=a*(5-2)^2 -> 1=a*9
So, a=1/9! Written in another form:
1/9x^2-4/9x+4/9-1

Hope could help :)

I'll make you brainlist and 40 points <br><br>(2z²)^-3<br><br>please hurry<br>​
gladu [14]
Is the goal to simplify? You just need to multiply the exponents for each factor:

(2z^2)^(-3)
= 2^(-3) x z^(2 x -3)
= (1/2)^3 x z^(-6)
= (1/8) x (1/z)^6
= 1/(8z^6)
