To dilate an object using a given scale factor we can multiply the coordinates of the object by the scale factor to get the coordinates of the image. However, this can only be done when the center of dilation is the origin (0,0). For non-origin center of dilation like in our case we have to locate the points of the image by construction in a Cartesian plane using the center and the scale factor. In this case we need to measure the distance of A from a point F (center of dilation) the we multiply it by 0.25 (the scale factor) then using the same path we measure the distance we get to locate point A'. Hence, by so doing point A' will be (1,0).

Anyone know this? I’m having a hard time with it
Orlov [11]

Answer:

75π

Step-by-step explanation:

The formula for volume of a cone is  (r^2h\pi)/3. If you substitute 5 into the radius and 9 into the height, you get (5^2*9\pi)/3=25*9\pi/3=25*3\pi=75\pi

At higher altitudes, water boils at lower temperatures. This relationship between altitude and boiling point is linear. At an al
Mashutka [201]

Let's assume

boiling point is y

altitude is x

we are given

This relationship between altitude and boiling point is linear

At an altitude of 1000 feet, water boils at 210°F

so, first point is (1000,210)

so, x1=1000 , y1=210

At an altitude of 3000 feet, water boils at 206°F

so, second point is (3000,206)

so, x2=3000,y2=206

now, we can find slope

m=\frac{y_2-y_1}{x_2-x_1}

now, we can plug values

m=\frac{206-210}{3000-1000}

m=-\frac{1}{500}

now, we can use point slope form of line

y-y_1=m(x-x_1)

so, we can plug it

y-210=-\frac{1}{500}(x-1000)

so, point slope form of line is

y-210=-\frac{1}{500}(x-1000)

now, we can plug x=8000

and then we can solve for y

y-210=-\frac{1}{500}(8000-1000)

y=196

So,

the boiling point of water at an altitude of 8000 feet is 196°F..........Answer
