For solving of the area of a square pyramid, we can use the formula below:
A=a²+2a sqrt (a²/4 +h²)
where s for the slant height, r for the a/2, where a is the side length and h for the height
Substitute the values,
A=40²+(2*40) SQRT (40²/4 +21²)
A=3920
The answer is 3920 for the area of the square pyramid.
Answer:
The distribution of multiple groups can be compared by analyzing the histogram of two data. The histogram analysis of multiple groups can be compared and analyzed by observing the following features of histograms. Shape: whether the shapes of distribution are alike or different from each other.

Answer:
- reflection over y = 2.5
- translation left 1
Step-by-step explanation:
The orientation of the triangle is reversed, so a reflection is required. Horizontal lines remain horizontal, but up/down are reversed, so the reflection is across a horizontal line. The horizontal line that is halfway between each point and its image is the line y = 2.5.
The x-coordinates of the image points are 1 less than the x-coordinates of the original, so a left shift of 1 unit is involved.
The two transformations to get from A to B could be (in any order) ...
- reflection over the line y = 2.5
- translation left 1 unit
__
The transformation can be summarized by ...
(x, y) ⇒ (x -1, 5 -y)
Solve for x the. You can find your answer from there.
