Write the quadratic function in vertex form, then identify the vertex

34kurt

Answer:

vertex = (- 10, - 10 )

Step-by-step explanation:

The equation of a quadratic in vertex form is

y = a(x - h)² + k

where (h, k ) are the coordinates of the vertex and a is a multiplier

To obtain this form use the method of completing the square.

Given

h(x) = x² + 20x + 90

add/subtract ( half the coefficient of the x- term )²

h(x) = x² + 2(10)x + 100 - 100 + 90

= (x + 10)² - 10 ← in vertex form

with (h, k ) = (- 10, - 10 )

How do you solve 4.23-5(0.04+0.09) step by step?

gtnhenbr [62]

Answer:

-0.04

Step-by-step explanation:

4.23-5= -0.77

-0.77*0.04= -0.03

-0.77*0.09= -0.07

-0.07 + -0.03= -0.04

According to a report by Scarborough Research, the average monthly household cellular phone bill is $73. Suppose local monthly h

marta [7]

Answer:

The probability that a randomly selected monthly cell phone bill is less than $95 is 0.9772

Step-by-step explanation:

The average monthly household cellular phone bill is $73.

$\mu = 73$

Local monthly household cell phone bills are normally distributed with a standard deviation of $11.

$\sigma = 11$

We are supposed to find the probability that a randomly selected monthly cell phone bill is less than $95 i.e.P(x<95)

$Z=\frac{x-\mu}{\sigma}$

$Z=\frac{95-73}{11}$

Z=2

Refer the z table for p value

So,p value = 0.9772

Hence the probability that a randomly selected monthly cell phone bill is less than $95 is 0.9772
