Ez so person 1 and person 2 are in a bike race. person 1 starts at the 10 ft line and travels 4 ft per second. person 2 starts at 15 ft line but travels 3 ft per second.
h(t) = -16t² + 50t + 5
The maximum height is the y vertex of this parabola.
Vertex = (-b/2a, -Δ/4a)
The y vertex is -Δ/4a
So,
The maxium height is -Δ/4a
Δ = b² - 4.a.c
Δ = 50² - 4.(-16).5
Δ = 2500 + 320
Δ = 2820
H = -2820/4.(-16)
H = -2820/-64
H = 2820/64
H = 44.0625
So, the maxium height the ball will reach is 44.0625
Answer:
The reciprocal of -7/9 is -9/7
Step-by-step explanation:
A reciprocal of a number is the multiplicative inverse of said number. In other words,
The reciprocal of x/y is y/x
Therefore, the reciprocal of -7/9 is -9/7
Step-by-step explanation:
Answer 3
multiply 4 by -20
1/4×-20
= -20/-20
= 1 answer
