Answer:
Max height: 64 feet, and the socond one was higher.
Step-by-step explanation:
The max height is the y value of the vertex, because that’s when the graph peaks.
we can already very clearly see the vertex on the graph, so we don’t need to calculate it.
the max height of the second golf ball is 64 feet.
Now let’s look at the max height on the first golf ball.
we get the equation
h=-16t squared + 48t
to find the vertex of this, we can use the formula -b/2a
-48/-32 = 1.5
1.5 is the t value of this vertex.
to find the h value, we plug it in.
h = -16 (1.5) squared + 48(1.5)
h =2.25 times -16 + 72
h = -36 +72
h = 36
the first one is 36 max height, and the second is 64. The second one is bigger.
4= 4.0
7/8= <span>0.875

In general for a rectangle of dimensions w by h and a semicircle of diameter w we get an area:

The halfs are because a semicircle is half a circle and a radius is half a diameter.
We're told

Substituting,

Answer: B
15 gallons of 35% peroxide solution contains 0.35 × 15 = 5.25 gallons of hydrogen peroxide. The rest of the volume is made up of 15 - 5.25 = 9.75 gallons of water.
If we add
gallons of water to the solution, the amount of hyrdrogen peroxide in the solution stays the same, but the volume of water increases to
gallons, and the total volume increases to
gallons.
To get a concentration of 8% in this diluted solution, we add
gallons of water such that

Solve for
.




To get the desired concentration, one must add 50.625 gallons of water, and one will end up with a total volume of 65.625 gallons of solution.
I would assume that you convert 2.5 ounces into punds which would make it 0.15 lbs.
