A circle has a diameter of 12 units, and its center lies on the x-axis. what could be the equation of the circle? check all that
wariber [46]

The equation of a circle with radius of 6 units and center on the x axis could be (x - 6)² + y² = 36

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

The circle has a diameter of 12 units. Hence, radius = 12/2 = 6 units.

The center of the circle is at x axis (*, 0), the equation could be:

(x - 6)² + (y - 0)² = 6²

(x - 6)² + y² = 36

The equation of a circle with radius of 6 units and center on the x axis could be (x - 6)² + y² = 36

On a map to cities are about 50 mm apart if the scale is 1 cm equals 15.5 miles how far apart are the two cities
Mademuasel [1]

Given:

On a map to cities are about 50 mm apart.

Scale is 1 cm equals 15.5 miles.

To find:

The distance between two cities.

Step-by-step explanation:

We have,

1 cm = 15.5 miles

It means

10 mm = 15.5 miles             [1 cm = 10 mm]

Now,

10 mm on a map = 15.5 miles

1 mm on a map = \dfrac{15.5}{10} miles

                          = 1.55 miles

50 mm on a map = 50 × 1.55 miles

                            = 77.5

Therefore, the two cities are 77.5 miles apart.

Somebody please help me with this ASAP I need the answers to the whole thing!! Please
cricket20 [7]

Answer:

(-2, 3 )

(-1, 2\frac{1}{2})

(0, 2)

(1, 1\frac{1}{2})

(2, 1)

Step-by-step explanation:

You just simply substitue the values given into the equation, and the answer worked out will be the value of y.

a = - \frac{1}{2} × -2 + 2 = 1 + 2 = 3

b = - \frac{1}{2} × -1 + 2 = \frac{1}{2}  + 2 = 2\frac{1}{2}

c =  -\frac{1}{2} × 0 + 2 = 0 + 2 = 2

d = -\frac{1}{2} × 1+ 2 =  -\frac{1}{2}  + 2 = 1\frac{1}{2}

e = -\frac{1}{2} × 2+ 2 = -1 +2 = 1

Hope this helps you :)

I’ll give you an extra 60 points please me within 5 minutes
azamat

Answer: (3p^2 + 1) . (p^3 +4)

Step-by-step explanation:

Area of a rectangle equals length multiplied by width. Given length as 3p^2 + 1 and width as p^3 + 4

Area = 3p^2 + 1) . (p^3 +4)

This is so as 4 is not a cube and cannot be factored.

I hope this helps.
