The value of P in the expression [tex]x^2-10x+P=(x-A)(x-B)[/tex] is 25

Given the expression [tex]x^2-10x+P=(x-A)(x-B)[/tex]

To get the value of P, we will use the completing the square method;

Add the square of the half of the coefficient of x

Hence the complete quadratic expression will be [tex]x^2-10x + 25[/tex]

Hence the value of P in the expression [tex]x^2-10x+P=(x-A)(x-B)[/tex] is 25

128 = 2^7

There are just seven 2's being multiplied to get to 128,

We know that the factors of 128 are :  1, 2, 4, 8, 16, 32, 64, and 128 itself.

But we need a prime factorization, and so [tex]2^{7}[/tex] is the prime factorization of that number

Answer:

about 12 1/2 minutes

each mile he went to school took him 5 minutes and if his friend's house is 2 1/2 miles away then 2.5x5= 12.5

======================================================

Work Shown:

20 min = 20/60 = 1/3 of an hour

distance = rate*time

d = r*t

4 mi = (x mph)*(1/3 hr)

4 = x*(1/3)

4*3 = x

x = 12 mph

Damon's speed is 12 mph

--------------

Now calculate the time it takes go travel to his friends house.

d = r*t

2.5 = 12*t

t = (2.5)/12

t = 25/120

t = (5*5)/(5*24)

t = 5/24

He takes 5/24 of an hour to go from school to Stefan's house.

Multiply by 60 to convert to minutes

(5/24)*60 = 12.5 minutes

The total amount that Ella earned in a week in which she made sales of $600 is; $500

The parameters given about Ella who is a salesperson are;

Amount paid per week = $500

Commission on sales exceeding $800 = 3%

Total sales for the week = $600

From the parameters above, we see that she didn't make sales exceeding the commission limit of $800 and as such she didn't earn any extra commission.

Therefore her weekly pay was still $500

Answer:

The price of rice per gram is 0.006$

Step-by-step explanation:

I. David wants to make 10 servings,

each require 75 g of rice and 5 spice. When ratio is 15:1

If rice : spice = 75 : x

15x = 75

x = 5

=> 5 * 15 : 1 * 5

= 75 : 5

So rice : spice is  75 : 5

II. When 1 serving require 75 : 5

So 10 servings is 10 * 75 : 5 * 10

= 750 : 50

So he must has 750 grams rice and 50 grams spice.

III. He must buy spice and rice which..

a) He has 40 grams spice, he'll buy for 10 grams spice.

b) He has no rice, he'll buy for 750 grams rice.

But the question only ask for price of rice which he spend 4.5$

=  [tex]\frac{4.5}{750}[/tex]

= 0.006$

In 1 gram of rice he spend 0.006$

If 750 grams of rice, he'll spend 750 * 0.006$ = 4.5$ => true

That makes 0.006$ is the right answer.

Hope that help :)

Lower quartile is negative 1

Because the middle number is the median because there is an odd set of numbers.

To find the quartile you have to arrange the numbers from lowest to highest.

When you find middle number you have to find the half of the lower half of the middle, which you will solve the lower quartile. Since there are even numbers you add the two middle numbers and divide it by 2. And you'll get the answer hope that helped

Answer:

y = - x + 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 2, 4 ) and (x₂, y₂ ) = (2, 0 )

m = [tex]\frac{0-4}{2-(-2)}[/tex] = [tex]\frac{-4}{2+2}[/tex] = [tex]\frac{-4}{4}[/tex] = - 1 , then

y = - x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (2, 0 )

0 = - 2 + c ⇒ c = 0 + 2 = 2

y = - x + 2 ← equation of line

Answer:

g = 8

Step-by-step explanation:

slope formula: (y2-y1)/(x2-x1)

-1 = (-6 -7) / (g +5)

-1= -13/x + 5

-1(x+5)= -13

-x - 5 = -13

-x = -8

x = 8
