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
It is given in the question that, The area of ava rectangular back yard is 325 square yards and the length of the yards is 13 yards.
Let the width be w yard .
And area of rectangle is the product of length and width .
So we have
Dividing both sides by w
So the width is 25 yards .
Answer: 3/4
Step-by-step explanation: Given that B is the event occurring and A is the event that has happened, we will use 36/48 as our probability. Once simplifying the numbers, you will get .75 or 3/4.
I think the variation is x. because for have the y-intercept if yo move x
Answer:
A is the answer
12 in
first substitute the variables
then 78=1/2h(5 + 8)
this makes it an equation
add similar terms which equals to
78=1/2xhx13
then divide both sides by 13
6=1/2xh
lastly divide both sides by 1/2
12=h
Step-by-step explanation:
proof
A=1/2x12(5 + 8) then
A=1/2x12x13 then
A=6x13 then
A= 78in^2
