Answer:
Step-by-step explanation:
tan61=FD/24
FD=24tan61
tan19=DE/FD
DE=FDtan19, since FD=24tan61
DE=(24tan61)(tan19) (exact)
DE=14.9 units (rounded to nearst tenth)
Though they might round to 15 units...
I'm assuming you have the octagonal base flat on the ground/floor. If so, then the horizontal cut through the center would basically cut the prism into two smaller equal pieces. Each piece will have the same octagonal base, but now the height is half as much. The cross section is the same as the base.
One way to picture it is to imagine you had a single room house with a very tall ceiling. Now place a floor between the top and bottom, midway through, so that you divide this house into too stories (each story being the same height). This new floor is a cross section, which is identical to the original floor of the house. Instead of a rectangular floor, picture the floor shape being an octagon.

What is inequlaity?</h3>
In Algebra, inequality is a Mathematical statement that shows the relation between two expressions using the inequality symbol.
Given
Samuel is running a 3-mile race.
He would like to finish the race in under 33 minutes.
He has already run for 10.5 minutes.
Let, x be the number of the minutes left for the race.
The inequality represent the situtation is;
Hence, the inequality represent the situtation is 10.5 + x < 33.

The coefficients of x4 is 9. It has factors of 1, 3, and 9. The constant is 4. It has factors of 1, 2, and 4.
The (positive and negative) ratios of the factors of the coefficient of the x4 and the constant 4 are the potential rational roots of the function.
The answers are:
1, -1, 3, -3, 9, -9, 1/2, -1/2, 3/2, -3/2, 3/4, -3/4, 9/2, -9/2, 9/4, -9/4
Let s be the slow train, and s+22 be the faster one. Then:
976/s+s+22=4
976=8s+88
8s=888
s=111 kph as the slower train
s+22=133 kph as the faster train
