Answer:
Kindly check explanation
Step-by-step explanation:
Suppose that the height s of a ball (in feet) at time t (in seconds) is given by the formula
s(t) = 64 - 16(t - 1)^2
t interval = 0 ≤ t ≤ 3
1) point A (from the graph)
11) Height of ball when it was released
Ball was released at t = 0
s(0) = 64 - 16(0 - 1)^2
= 64 - 16(-1)^2
= 64 - 16(1)
= 64 - 16
= 48 feets
111) point C ( from the graph)
IV) highest point of the ball is 64
Hence,
s(t) = 64 - 16(t - 1)^2
64= 64 - 16(t - 1)^2
16(t - 1)^2 = 64 - 64
16(t - 1)^2 = 0
16t^2 - 32t + 16 = 0
t^2 - 2t + 1 = 0
(t-1) = 0 (t-1) = 0
t = 1
V) Point G (from graph)
V1)
height = 0
s(t) = 64 - 16(t - 1)^2
0 = 64 - 16(t - 1)^2
16(t - 1)^2 = 64
(t - 1)^2 = 64/16
(t - 1)^2 = 4
(t - 1)² = 2²
t - 1 = 2
t = 2 + 1
t = 3

Answer:
Step-by-step explanation:
As 5 ⋅ 5 ⋅ 7 ⋅ 7 ⋅ 7 = 5² ⋅ 7³ = 8575
Exponential notation: 5² ⋅ 7³
Decimal Notation: 8575
i) 3 ⋅ 8 ⋅ 7 ⋅ 7 ⋅ 7 ⋅ 8 = 3 . 7³ . 8² = 65856
Exponential notation: 3 . 7³ . 8²
Decimal Notation: 65856
ii) 7 ⋅ 7 ⋅ 7 ⋅ 7 ⋅ 6 ⋅ 3 = 3 . 6 . 7⁴ = 43218
Exponential notation: 3 . 6 . 7⁴
Decimal Notation: 43218
Answer:
140 degrees.
Step-by-step explanation:
Because BD is a tangent to the circle the angle ABD = 90 degrees.
So m < BAD = 180 - 90 - 50
= 180 - 140 = 40 degrees. ( as there is 180 degrees in a triangle).
So m < BAF = 180 - 40 = 140 degrees (adjacent angles).
