A^2=49 and b^2=64, which of the following cannot be a value of a+b

1 answer:

7 0

The values of A and B have to be 7 and 8, respectively. Unless you also deal with negatives, which also means you can have -7 and -8 as values. So, anything besides 7, 8, -7, and -8 cannot be values.

Pizza planet is running a sell 3 pizzas for $16.50. What is the unit rate for one pizza?

8090 [49]

Answer:

$5.30

Step-by-step explanation:

$16.50 = (3)p

[p = pizza]

To solve you have to separate the p by removing the (x3)

1) Divide both sides of the equation by 3

[ 16.50 / 3 = p}

2) Divide 16.50 by 3

[5.30]

3) 5.30 = p

The profit from a business is

GuDViN [60]

First of all we will understand the question!!

The question is saying that you are given a function and you have to find the value of x which will give the maximum profit... Lets solve it by finding the extrema using the vertex

 $\rm \: p(x) = - 5 {x}^{2} + 30x + 8$ 

Identify the coefficients a and b of the quadratic function

 $\rm \: p(x) = { - 5x}^{2} + 30x + 8 \\ \rm \: a = - 5 \: and \: b \: = 30$ 

Since a<0, the function has the maximum value at x, calculated by substituting a and b into x=-b/2a

$\rm \: x = \frac{30}{ 2 \times (- 5)}$

Solve the equation for x

$\rm \: x = 3$

The maximum of the quadratic function is at x=3
