Answer:

x^2+(y-1)^2=225

Step-by-step explanation:

we know that

The equation of the circle in center radius form is equal to

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

where

(h,k) is the center of the circle

r is the radius of the circle

In this problem we have

(h,k)=(0,1)\\r=15\ units

substitute

(x-0)^2+(y-1)^2=15^2

x^2+(y-1)^2=225

359 rounded to nearest 100 = 400

309 rounded to nearest 100 = 300


800 + 400 + 300 = $1,500 estimated total cost

Describe the slope of the line<br> Find the slope
Dmitry_Shevchenko [17]

Answer:

Question one: Zero slope
Question two: m=\frac{0}{4}

Step-by-step explanation:

Given the following questions:

<u>Question one:

</u>The following line is what you call a "zero slope." Zero slopes are lines that are neither decreasing or increasing and remain at a constant or just a straight line.

Question two:

Point A = (-2, -3) = (x1, y1)
Point B = (2, -3) = (x2, y2)

Using the formula for slope or rise over run we will solve and find the slope of this line.

m=\frac{y2-y1}{x2-x1}
m=\frac{-3--3}{2--2} =\frac{0}{4}
m=\frac{0}{4}

The slope of this line is "0/4."

Hope this helps.

Identify the volume and surface area of the hemisphere in terms of π. HELP ASAP!!
posledela

Answer:

D

Step-by-step explanation:

Use the formula for the SA of a hemisphere.

SA=2\pi r^2

Now we can find the radius of the hemisphere, which is 15.

Then, we can square that and multiply it by 2 to get 450.

Now, let's use the formula for the Volume of a hemisphere.

V=\frac{2\pi r^3}{3}

Now we can cube 15 and multiply it by 2 to get 6750.

Then we can divide this number by 3.

2250.

So the answer is D.
