The two points (2,4) and (9,4) are the endpoints of the diameter of a circle. What is the equation of this circle in standard fo

denis23 [38]

The midpoint of the diameter endpoints is the center of the circle...

((2+9)/2, (4+4)/2)

(5.5, 4) is the center of the circle...

The distance between the two endpoints is the diameter of the circle...

d^2=(4-4)^2+(9-2)^2

d^2=0+49

d^2=49

d=7

So the radius is d/2 which is 3.5

Now the equation of a circle is:

(x-h)^2+(y-k)^2=r^2 where (h,k) is the coordinates of the center and r is the radius.

Earlier we found (h,k) to be (5.5, 4) and r=3.5 so our equation is:

(x-5.5)^2+(y-4)^2=3.5^2

(x-5.5)^2+(y-4)^2=12.25

A store manager predicts that 150 blankets will be sold if each blanket

Sever21 [200]

Answer:

$47

Step-by-step explanation:

Given: Store manager have predicted that 150 blanket can be sold at $32 each.

Also he has predicted sales of 2 blanket will decrease with $1 increase in price.

Now, finding price at which 120 blanket can be sold.

As we know cost of 150 blanket is $32 and we are finding for 120 blanket, which mean we have to increase price to decrease sales.

∴ $150-120 = 30\ blankets$

Using unitary method to find correct price.

For 2 decrease in sales = $1 increase in price

∴ 30 decrease in sales of blanket = $15 increase in price

Next, price of 120 blanket = $Price of 150\ blanket + increase\ in\ price$

Price\ of\ 120\ blanket = $32+15 = \$ 47$

∴ $47 should be the price for at least 120 blanket to be sold.

Spiral Homework<br>Chapter 3 Lesson 5<br>-ach expression.<br>2. 3(-3) + 17<br>5. -21(3) + (-19)

tankabanditka [31]

2. $3(-3)+17=8$

3. $-21(3) + (-19)=-82$

Step-by-step explanation:

We need to solve the following expressions.

2. $3(-3)+17$

Solving we get:

$3(-3)+17\\=-9+17\\=+8$

5. $-21(3)+(-19)$

Solving we get:

$-21(3) + (-19)\\=-63+(-19)\\=-63-19\\=-82$
