Answer:

The first one.

Step-by-step explanation:

The third and fourth ones can't be right because at when the line takes its first curve (just before .25 hours) it doesn't keep increasing in height, and she walked during that time.

The second one can't be right because when she started out she wasn't immediately between 1.25 and 1.5 miles.

That leaves only the first one.

What is the volume of the pyramid if the height is 215 and the base is 339

inna [77]

Answer:

$V=8,236,005\ ft^3$

Step-by-step explanation:

The correct question is

The great Pyramid of Menkaure has a height of about 215 feet and a base side length of about 339 feet. What is its volume?

we know that

The volume of a square pyramid id equal to

$V=\frac{1}{3}b^2h$

where

b is the length side of the square base

h is the height of pyramid

we have

$b=339\ ft\\h=215\ ft$

substitute

$V=\frac{1}{3}(339)^2(215)$

$V=8,236,005\ ft^3$

Are the graphs y=4x-4 and 24x-4y=96 parallel

nydimaria [60]

$k:y=m_1x+b_1;\ l:y=m_2x+b_2\\\\k\ ||\ l\iff m_1=m_2\\\\k:y=4x-4;\ l:24x-4y=96\\\\24x-4y=96\ \ \ \ |subtract\ 24x\ from\ both\ sides\\-4y=-24x+96\ \ \ \ |divide\ both\ sides\ by\ (-4)\\y=6x-24\\\\m_1=4;\ m_2=6\Rightarrow m_1\neq m_2$

Answer: The graphs y = 4x - 4 and 24x - 4y = 96 are not parallel.
