8. 1,728 i did 12×18÷2=108×32=345÷2= 1,728
Step-by-step explanation:
do 21×3.14= 65.94
then divide by 2 since its a semicircle
equals: 32.97
than find perimeter altogether
21+28+28+32.97= 109.97ft
Answer:
A diver can descend 2 feet every minute. If the diver descends for four minutes, where will the diver be in relation to the surface?
Step-by-step explanation:
If the surface is 0 and the diver descends a total of eight feet, then the diver would be at a position of -8 feet.
Answer:
y = -3/8x -41/8
Step-by-step explanation:
Perpendicular lines intersect at 90° and their slopes are opposite reciprocals.
Therefore the slope changes from 8/3 to -3/8.
Now we must solve for the new y-intercept (b) by plugging in the given coordinate (-3,-4).
The result is b = -41/8 so our new equation is:
y = -3/8x -41/8
