Find the volume. 74yd 54yd 84yd 103yd
1 answer:
The volume of the figure in the attachment is 84 cubic yards
<h3>What is the volume of a figure?</h3>The volume of a figure or a three-dimensional shape is the amount of space inside the figure or the three-dimensional shape
<h3>How to determine the total volume?</h3>The complete question is added as an attachment.
From the attached figure, we can see that the three-dimensional shape is a frustum
The volume is then calculated using the following formula
V = 1/2 * (Sum of the parallel bases) * height * side length
From the figure, we have:
Parallel bases = 2 yards and 6 yards
Height = 3.5 yards
Side length = 6 yards
Substitute the known values in the above equation
V = 1/2 * (2 + 6) * 3.5 * 6
Evaluate the product in the above equation
V = 1/2 * (2 + 6) * 21
Evaluate the sum in the above equation
V = 1/2 * 8 * 21
Evaluate the product in the above equation
V = 1/2 * 168
Evaluate the product in the above equation
V = 84
Hence, the volume of the figure in the attachment is 84 cubic yards

Answer:
Step-by-step explanation:
We have the following function
y = 12^x, and we need to find the inverse function.
To find the inverse function we should solve the equation for "x". To do so, first, we need to:
1. Take the logarithm in both sides of the equation:
lg_12 (y) = log _12 (12^x)
(Please read lg_12 as: "Logarithm with base 12")
From property of logarithm, we know that lg (a^b) = b*log(a)
Then:
lg_12 (y) = x*log _12 (12)
We also know that log _12 (12) = 1
Then:
x = log_12(y).
Then, the inverse of: y= 12^x is:
