Answer:

y +1 = -3(x -3)

Step-by-step explanation:

The given point is (3, -1), and the given slope is -3. The form suggests you want the point-slope form of the equation for the line:

y -k = m(x -h) . . . . . . . . line with slope m through point (h, k)

Using the given values, the equation is ...

y -(-1) = -3(x -3)

y +1 = -3(x -3)

(a) The rate that the point 8,28 represents is 3.5 cm/s since 28/8 = 3.5
(b) The unit rate is 3.5 cm/s since the rate is constant.
(c) The two points lie on the same line and that both points results to a rate of 3.5 cm/s.<span />

Answer:

19.6 cubic centimeters

Step-by-step explanation:

The ratio of two similar 3D figures' volumes is equivalent to the ratio of their corresponding lengths (whether it's width, height, length, radius, etc) cubed.

Here, we know the cones are similar, and we know the smaller radius is 2 and the larger radius is 3. Then the ratio of the volume of the smaller one to the volume of the larger one is $(2/3)^3=8/27$ .

We also know the actual volume of the larger cone is 66. So, if x is the volume of the smaller cone, we have the proportion:

x / 66 = 8 / 27

Cross-multiply:

27x = 66 * 8 = 528

Divide by 27:

x = 528/27 ≈ 19.6

The answer is thus 19.6 cubic centimeters.
