Answer:
The equation is y = 4x + 5
Step-by-step explanation:
To find the equation to this table, pick two ordered pairs and use the slope formula to find the slope. For this we'll use (4, 21) and (8, 37).
m(slope) = (y2 - y1)/(x2 - x1)
m = (37 - 21)(8 - 4)
m = 16/4
m = 4
Now we can use that slope along with any point in point-slope form to find the equation.
y - y1 = m(x - x1)
y - 21 = 4(x - 4)
y - 21 = 4x - 16
y = 4x + 5
Answer:
A = 157 in^2
Step-by-step explanation:
First, we need to get the radius, we can do this by dividing our given diameter by 2.
20/2 = 10
Now, we have our radius of 10 inches.
Formula for Area of a Semi Circle: (1/2)(pi(r^2)
Input values.
(1/2)(3.14(10^2)
Solve.
(1/2)(3.14(100)
(1/2)(314)
1/2(314) = 157
Finally, we have our result which is 157 inches^2.
Answer: 3,003 cubic meters

Answer:
Step-by-step explanation:
Example of banking
Answer:
The length of each smaller piece, l=L/n inches
Step-by-step explanation:
This can be expressed as;
Total length=Length per piece×number of pieces
where;
The total length=L
length per piece=l
number of pieces=n
Substituting in the equation;
L=l×n
To get the length of each smaller piece;
l=L/n inches
solving;
l=30.75/3=10.25 inches
