Answer:
35.1 sq. feet.
Step-by-step explanation:
Here ABCD is a rectangle and AC is a diagonal. Hence, Δ ABC is a right triangle with AC = 9 feet and ∠ CAB = 30°.
So, from the right triangle Δ ABC,
⇒ BC = 9 sin 30° = 4.5 feet.
Again,
⇒ AB = 9 cos 30° = 7.794 feet.
Therefore, area of the rectangle is (AB × BC) = 4.5 × 7.794 = 35.1 sq. feet (Answer)
Answer:
Step-by-step explanation:
We have a bounce up and down
but, it is dropped from a height so the initial one doesn't count
we do
2(sum of all)-initial
infinite sum

a1=1
r=0.9

sum=1/0.1
sum=10
so
2(sum)-initial=2(10)-1=20-1=19
travels 19m
The graph shows the solution to be (x, y) = (-1, 3).
