Line p passes through A(-2, -4) and has a slope of 1/2 What is the standard form of the equation for line p?

1 answer:

4 0

Point slope form is y-(-4) = 1/2(x-(-2)

y+4 =1/2 (x+2)

now the standard form 2y+8=x+2
so -x+2y=-6 is the equation for line p in standard form

Answer:

1526.0 cubic units

Step-by-step explanation:

Rotating rectangle AKLM you will get cylinder with height KA and base radius KL. From the given data

$KA=\sqrt{(6-0)^2+(0-0)^2}=6,\\ \\KL=\sqrt{(0-0)^2+(9-0)^2}=9.$

The volume of the cylinder is

$V_{cylinder}=\pi r^2\cdot H.$

Then

$V_{cylinder}=\pi \cdot 9^2\cdot 6=486\pi \approx 1526.0\ un^3.$

Kelly pays $25/sweater wholesale.find the salling price if her mark-up is 65%?

gladu [14]

This is another way of saying what is 165% of 25, because 65% of the sweater is the markup, and you add the markup to the whole sale.
165% is 1.65 in decimal form, so $1.65*25=41.25$
$41.25$ is your answer

Need Help understanding this!! 40 points!!!

Eva8 [605]

Angles 1 and 2 are vertical angles which makes # 3 angle 1 = angle 2

Because angle 1 and 2 are vertical angles, then A and E would be similar due to the vertical angle theorem as well.

The answer would be D.
