C) (-5, 0)

Working;
Use the formula;
x coordinate=\frac{ k_{1}  x_{B}+ k_{2} x_{A}   }{ k_{1} + k_{2} }\frac{ k_{1} y_{B} + k_{2} y_{A}   }{ k_{1} + k_{2} }

A model rocket is launched straight upward. The solid fuel propellant pushes the rocket off the ground at an initial velocity of
anastassius [24]

Answer:

a) 72.25sec

b) 6.25secs

c) after 10.5secs and 2 secs

Step-by-step explanation:

Given the height reached by the rocket expressed as;

s(t)= -4t^2 + 50t - 84

At maximum height, the velocity of the rocket is zero i.e ds/dt  = 0

ds/dt = -8t + 50

0 = -8t + 50

8t = 50

t = 50/8

t = 6.25secs

Hence it will reach the maximum height after 6.25secs

To get the maximum height, you will substitute t - 6.25s into the given expression

s(t)= -4t^2 + 50t - 84

s(6.25) = -4(6.25)^2 + 50(6.25) - 84

s(6.25) = -156.25 + 312.5 - 84

s(6.25)  = 72.25feet

Hence the maximum height reached by the rocket is 72.25feet

The rocket will reach the ground when s(t) = 0

Substitute into the expression

s(t)= -4t^2 + 50t - 84

0 = -4t^2 + 50t - 84

4t^2 - 50t + 84 = 0

2t^2 - 25t + 42 = 0

2t^2 - 4t - 21t + 42 = 0

2t(t-2)-21(t-2) = 0

(2t - 21) (t - 2) = 0

2t - 21 = 0 and t - 2 = 0

2t = 21 and t = 2

t = 10.5 and 2

Hence the time the rocket will reach the ground are after 10.5secs and 2 secs

Please Help!
JulijaS [17]

Answer:8865=6000(1+\frac{5\times t}{100})

Step-by-step explanation:

Given

Liam deposited P=\$\ 6000

Rate of interest is R=5\ \%

If the amount after t years is A=\$\ 8865

Simple interest is given by

S.I.=\dfrac{P\times R\times t}{100}

And amount is

A=P+S.I.

A=P(1+\frac{R\times t}{100})

Substituting values we get

8865=6000(1+\frac{5\times t}{100})

1.4775=1+\frac{5\times t}{100}

0.4775\frac{5\times t}{100}

5t=47.75

t=\frac{47.75}{5}=9.55\ years
