Answer:

<em>Choice D.</em>

Step-by-step explanation:

Vertical line test for functions:

If a vertical line drawn anywhere on the graph intersects the graph in more than one point, it is not a function.

If you draw a vertical line passing through any point between x = -4 and x = 4, the line will intersect two points on the circle. The relation fails the vertical line test. That shows that this relation is not a function.

Earth's radius is approximately 6400 km. What is the surface area &amp; volume of the earth?
Tamiku [17]

Answer:

SA=514,457,600\ km^{2}

V=1,097,509,546,667\ km^{3}

Step-by-step explanation:

step 1

Find the surface area

we know that

the surface area of a sphere is equal to

SA=4\pi r^{2}

substitute

SA=4 \pi (6,400)^{2}

SA=163,840,000 \pi\ km^{2}

substitute the approximate value of pi (3.14)

SA=(3.14) (163,840,000)

SA=514,457,600\ km^{2}

step 2

Find the volume

The volume is equal to

V=(4/3)\pi r^{3}

substitute

V=(4/3)(3.14) (6,400)^{3}

V=1,097,509,546,667\ km^{3}

Please answer the question on the attachment &lt;3
nika2105 [10]

Answer:

Step-by-step explanation:

hypotenuse (h) = 9.4

base(b) = 1.9

cos x = b/h

cos x = 1.9/9.4

x = cos ^-1 ( 1.9/9.4)

x = 78.3°

hope it will help :)

Johan found that the equation –2|8 – x| – 6 = –12 had two possible solutions: x = 5 and x = –11. Which explains whether his solu

It should be x=11 instead of x=-11, so he is not correct because he made a sign error.
