Answer:
216*y*y*y*y
Step-by-step explanation:
6 cubed is 216, and y^4 expanded is yyyy. So if I'm understanding correctly, you want as your answer:
216*y*y*y*y
Answer:
either 449/25 or 11/25 depends on the -14/5 or
Step-by-step explanation:

if it the first one then the answer should be 449/25 but if ut the second one it should be 11/25 .
u just substitute the -14/5 to x then solve
He gets 7.80 an hour so you multiply 7.8 by 5.25 hours
Answer:
Respondió mal 64 preguntas.
Step-by-step explanation:
De acuerdo a la información proporcionada puedes plantear las siguientes ecuaciones:
x+y=120 (1)
2x-0,5y=80 (2)
x es el número de preguntas correctas
y es el numero de preguntas incorrectas
Primero debes despejar "x" en (1):
x=120-y (3)
Después, debes reemplazar (3) en (2):
2(120-y)-0,5y=80
240-2y-0,5y=80
240-80=2,5y
160=2,5y
y=160/2,5
y=64
Ahora puedes reemplazar el valor de "y" en (3) para encontrar el valor de "x":
x=120-y
x=120-64
x=56
De acuerdo a esto, la respuesta es que el postulante respondió mal 64 preguntas.
Answer:
The ball will hit the ground at 10 seconds and its maximum height is 1024 feet.
Step-by-step explanation:
Height of a mountain, h = 90 feet
Upward velocity of a ball, u = 64 ft/s
Its height as a function of time can be written by using the second equation of motion as follows :
.....(1)
When it will hit the ground, f(x) = 0

It is quadratic equation.
t = -6 s and t = 10 s
Neglecting -6 seconds, the ball will hit the ground at 10 seconds.
For maximum height,
Put f'(x) = 0

Put t = 2 in equation (1)

Hence, the ball will hit the ground at 10 seconds and its maximum height is 1024 feet.
