Sean and mason run out of gas while fishing from their boat in the bay. They set off an emergency flare with and initial velocit

y of 30 meters per second. The height of the flare in meters can be modeled by h(t) = -5t^2 + 30t, where t represents the number of seconds after launch. Sean wants to know how high the flare will reach above the surface of water. a. Write the function in vertex form, factoring so the coefficient of t^2 is 1. b. Complete the square using the vertex form of the function. c. How high will the flare reach?

Serjik [45]
Let
c----------->  represent the cost of each shirt without discount
t-----------> <span>total cost for the three shirts after the discount
d----------> discount

we know that
d=3c*0.20
t=3c-d-------------> 3c-[3c*0.20]--------> 3c*[1-0.20]=3c*(0.80)

the answer is 3c*(0.80)</span>

Can u plz help i need the unser right now!!
Dahasolnce [82]

Answer:

C

Step-by-step explanation:

Solving the inequality

\frac{1}{2} x - 2 > 0 ( add 2 to both sides )

\frac{1}{2} x > 2 ( multiply both sides by 2 )

x > 4

Since greater than 4 we want a number line with an open circle at 4, indicating x is not equal to 4 and arrow pointing to the right.

Hence C

Answer:

Ver explicacion

Step-by-step explanation:

Dado que el precio en efectivo del camión es de $ 80 000. Luego;

P = $ 80 000

R = 16%

T = 2 años

Yo =?

Pero

I = PRT / 100

Yo = 80 000 * 16 * 2/100

I = $ 25,600

Importe total pagado = principal + intereses

Monto total pagado = 80,000 + 25,600

Monto total pagado = $ 105,600
