nasty-shy [4]4 years ago
4 0

Answer:

Negative Correlation

Make p the subject of the relation A is equal to 1/2 ( p + b) h​
Amanda [17]

Answer:

2A /h  -b =p

If you need it with a common denominator

(2A -bh)/h = p

Step-by-step explanation:

A = 1/2 ( p+b)h

Multiply each side by 2

2A =  ( p+b)h

Divide by h

2A/h =  ( p+b)h/h

2A/h =  ( p+b)

Subtract b

2A/h   -b =   p+b -b

2A /h  -b =p

If you need it with a common denominator

(2A -bh)/h = p

The volume of the stones will be 384 inch³.he volume of the stone is found by subtracting the volume before stones and the volume after stones in the container.

<h3 /><h3>What is volume?</h3>

The term “volume” refers to the amount of three-dimensional space taken up by an item or a closed surface. It is denoted by V and its SI unit is in cubic inch.

Volume before the stones are put in the container is;

\rm V_1 = L bh \\\\ V_1= 4 \times 16 \times 8 \\\\ V_1= 512 \ inch^3

The volume after the stones are put in the container is;

\rm V_2= 7 \times 16 \times 8 \\\\\ V_2= 896 \ inch^3 \\\\

The volume of the stone is found by subtracting the volume before stones and the volume after stones;

\rm V = V_2-V_1 \\\\\ V=896-512 \\\\ V_2= 384 \ inch^3

Hence,the volume of the stones will be 384 inch³.

What is an equation of the line that is parallel to y=4x−10 and passes through (1, 13) ? Enter your equation in the box.
Evgen [1.6K]

y = 4x−10 ; slope m = 4

Parallel has same slope so slope of new line = 4

y = 4x + b

b = y - 4x

Passes through (1, 13)

b = 13 - 4(1)

b = 13 - 4

b = 9

Equation

y = 4x + 9
