What is the surface area of cone below Diameter AB=21 and distance from B to C =36
Vesnalui [34]

Answer:

1533.88261311522

Step-by-step explanation:

<em>Let r be the radius of the (base/circle)</em>

<em>and  L be the slant height of the cone</em>

<em>Formula ………………………………………………………………………………………………………</em>

The surface area of a cone = the (curved/lateral) surface area +  the base

                                             =\pi r^{2}\ \ \ +\ \ \ \pi Lr

=========================================

r=\frac{21}{2} =10.5

L = BC = 36

\text{surface area} =\pi \left( 10.5\right)^{2}  +\pi \times 36\times \left( 10.5\right)

                   =346.360590058275 + 1187.52202305694

                   =1533.88261311522

Choose all that give the correct effect on the linear graph of the parent function ƒ(x).
Nataliya [291]

Answer: since the parent function is f(x), then i think....

f(x) + 5 is the shifted 5 units up of f(x)

then the first answer is correct

f(x - 8) is 8 shifted 8 units right of f(x)

then the second answer is wrong,

f(x) is replaced by 4f(x) means it stretched vertically by a factor of 4

the the third answer is correct

f(x) is replaced with f(3x) compressed horizontally by a scale factor of 1/3

then the fourth answer is correct

Step-by-step explanation: i hope this makes since and sorry if it doesn't so the first is correct, second is wrong, third is correct, and fourth is also correct. and no there well be no links. (sorry if you do want links)

A naval engineer uses the function, P, to analyze the effects of water pressure on submarines. The function P(d) measures the pr
saw5 [17]

The function that the naval engineer uses related P (pressure) and d (depth of ocean).

<em>Is there any restriction on the domain ( d: depth of the ocean)? Yes!</em>

The domain would be from 0 (at sea level or 0 depth) until the depth of the ocean (which is not infinite). Hence, we can write:

0\leq d\leq DepthOfSeaFloor

Choice D is the correct one.


ANSWER: D
