Answer:
shirt= $8
cap=$3
Step-by-step explanation:
rearrange one of the equations
y=11-x
then plug into the other equation
2x+3(11-x)=25
solve
2x+33-3x=25
-x+33=25
subtract 33 from both sides
-x=-8
divide by -1
x=8
the put that answer into original equation
8+y=11
subtract 8 from both sides
y=3
Somewhere you're given the equation for height as a function of time:
... h(t) = -16t² + v₀·t . . . . . . where v₀ is the initial vertical velocity in ft/s
For v₀ = 224, this becomes
... h(t) = -16t² + 224t
And this can be rewritten in vertex form as
... h(t) = -16(t² + 14t)
... h(t) = -16(t² + 14t +7²) +16·7² . . . . . complete the square (add the square of half the t coefficient inside parentheses; add the opposite of that amount outside parentheses)
... h(t) = -16(t +7)² + 784
The vertex of this downward-opening parabola is (7, 784), so ...
The rocket reaches its maximum height at 7 seconds.
The maximum height of the rocket is 784 feet.
Answer:
a) y = 5x
b) y = 60
Step-by-step explanation:
Since, y is directly proportional to x when y=30, x=6
