Answer:
<h2>At the 7th bounce, the ball reached 2.3 feet height.</h2>Step-by-step explanation:
The given expression is
This exponential function represents the movement of a bouncing ball after being dropped.
represents the bounce number.
So, at 7th bounce means , replacing this value in the function, we have
Therefore, at the 7th bounce, the ball reached 2.3 feet height.
Answer:
The measurement of EF is 1.98 units
Step-by-step explanation:
In Δ DEF
∵ m∠E = 90°
∴ FD is the hypotenuse of the triangle
∵ m∠D = 26°
∵ EF is opposite to angle D
- We can use the sine ratio to find it
∵ sin D = ⇒ (opposite side / hypotenuse)
∵ FD = 4.5 units
∴ sin(26) =
- Multiply both sides by 4.5
∴ 4.5 sin(26) = EF
∵ sin 26° ≈ 0.44
∴ 4.5(0.44) = EF
∴ 1.98 = EF
The measurement of EF is 1.98 units
