What is the value of h when the function is converted to vertex form?

elena-s [515]

Answer: h=7

Step-by-step explanation:

By definition the function in vertex form is:

$f(x)=a(x-h)^{2}+k$

Where (h,k) is the vertex of the parabola.

You must group the terms that contain the same variable in the function:

$f(x)=(x^{2}-14x)+29$

Complete the square as following:

$f(x)=(x^{2}-14x+49)+29-49$

Now you must rewrite it as following:

$f(x)=(x-7)^{2}-20$

Then:

h=7

Answer:

Choice C: 6.23

Step-by-step explanation:

$\frac{5}{100}$ = $\frac{x}{124.50}$ -----> cross multiply

5(124.50) = 100x

622.5 = 100x

$\frac{622.5}{100} = \frac{100x}{100}$

6.225 = x

6.225 rounded to the nearest hundredth is 6.23
