You would pick 2/3 idk but it sounds right
Answer:
h = 1600 feet
Step-by-step explanation:
To quickly solve this problem, we can use a graphing tool or a calculator to plot the equation.
Please see the attached image below, to find more information about the graph
The projectile formula is
h(t) = a*t^2 + v*t + h0
Where,
v = initial vertical velocity of the object in feet per second
h0 = initial height of the object in feet
h(t) = −16t^2 +160t + 1200
If we look at the graph, we can find the point in which the height becomes maximum.
For this problem,
h = 1600 feet ,
at t = 5 seconds
Answer:
9
Step-by-step explanation:
3n(n representa number of time)+2n =50
50÷2=25( shoveling side walk)
25÷3= 8.3333333333(mowling)
25+8.3333333333=33.3333333333
last year:
2n+ 3n=45
45÷5=9 ( divide 5 because you add 2+3)
shoveling once=9

Answer:
reflected over the x-axis, compressed horizontally by a factor of 1/2.
Step-by-step explanation:
y(x) and f(x) means the same.
y = -(2x) means that y(x) was multiplied by -1, and x was replaced by 2x
- -y(x) reflects y(x) across x-axis
- y(a*x) compresses horizontally y(x) by a factor of 1/a. Here, a is 2, then the factor is 1/2.
