Answer:

(x-10)^2 + (y-4)^2 = 16

Step-by-step explanation:

To write the equation using a center and a radius, use the vertex form of the equation.

(x-h)^2+(y-k)^2 = r^2

Substitute the values h=10 and k=4 into the equation along with r = 4.

(x-10)^2 + (y-4)^2 + 4^2\\(x-10)^2 + (y-4)^2 = 16

Part B if the height of each prism is 10 Cm what is the surface area prism
Evgen [1.6K]

Answer:

Prism A:

Area = 288cm^2

Prism B:

Area =250cm^2

Step-by-step explanation:

Given

See attachment for prisms

Height(h) = 10cm

Required

Determine the surface area of both prisms

Prism A is triangular and as such, the surface area is:

Area = 2 * A_b + (a + b + c) * h

Where

A_b = \sqrt{s * (s - a) * (s -b) * (s - c)}

and

s = \frac{a + b + c}{2}

Such that a, b and c are the lengths of the triangular sides of the prism.

From the attachment;

a = 8; b =6; c =10

So, we have:

s = \frac{a + b + c}{2}

s = \frac{8 + 6 + 10}{2}

s = \frac{24}{2}

s = 12

Also:

A_b = \sqrt{s * (s - a) * (s -b) * (s - c)}

A_b = \sqrt{12 * (12 - 8) * (12 - 6) * (12 - 10)}

A_b = \sqrt{576}

A_b = 24

So:

Area = 2 * A_b + (a + b + c) * h

Area = 2 * 24 + (8 + 6 + 10) * 10

Area = 288cm^2

Prism B is a rectangular prism. So, the area is calculated as:

Area = 2 * (ab + bh + ah)

From the attachment

a = b = 5

h =10

So:

Area =2 * (5 * 5 + 5 * 10 + 5 * 10)

Area =250cm^2

Solve the following inequality. Then place the correct answer in the box provided. Answer in terms of a mixed number. 2(P +1) +
Darina [25.2K]

Answer:

P>-\frac{6}{5}

Step-by-step explanation:

Isolate the variable by dividing each side by factors that dont't contain the variable.

2(P+1)+3(P+2)>2

2P+2+3P+6>2

5P+8>2

     -8    -8

5P>-6

Divide both sides by 5.

P>-\frac{6}{5}
