Answer:
y = 12
Step-by-step explanation:
The standard form of the exponential function is
y = a
Find a and b by substituting ordered pairs from the table into the equation
Using (0, 12 ), then
12 = a (
= 1 ), so
a = 12, then
y = 12
Using (1, 34.8 ) , then
34.8 = 12 ( divide both sides by 12 )
b = 2.9
Thus exponential function is
y = 12
Answer:
Length = 17 feet, Width = 5 feet
Step-by-step explanation:
Given:
The area of a rectangular wall of a barn is 85 square feet.
Its length is 12 feet longer than the width.
Question asked:
Find the length and width of the wall of the barn.
Solution:
Let width of a rectangular wall of a barn =
<u>As length is 12 feet longer than the width.</u>
Length of a rectangular wall of a barn =
As we know:
Subtracting both sides by 85
As width can never be in negative, hence width of a rectangular wall of a barn = = 5 feet
Length of a rectangular wall of a barn =
Therefore, length and width of the wall of the barn is 17 feet and 5 feet respectively.
Answer:
Area = 867 meters
Step-by-step explanation:
You have a rectangle. This means opposite sides are equal. If you set these expressions equal to each other, you will get two equations with two unknowns, x and y. Next, solve the system of equations to find x and y. Then, use the values to find the length and width of the rectangle. Last, multiply length × width to find the area.
