Answer:
h(t) = –16t^2 + 46*t + 6
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) = -16*t^2 + v*t + h0
Where,
v = initial vertical velocity of the ball in feet per second
h0 = initial height of the ball in feet
We need to fill the equation
h(t) = –16t^2 + v*t + 6
Where
v is the missing speed
If we go through many values of v until we find the same graph as the one showed in the first picture, we can find that
v = 46 ft/s
Libby wants to make cookies for her whole class. There are 36 students in her class. The recipe Libby is going to use only makes 12 cookies. How many batches of cookies is Libby going to have to make to feed her whole class?
36/12
It is going going to be 30 because 200+180 adds up to 380 and then 380-350 is 30
Answer:
- Small cups were 98
- Large cups were 57
Step-by-step explanation:
Ashley sold small cups of lemonade for $1.25 and;
Large cups of lemonade for $2.50
The total number of cups = 155 cups
Total sales = $265
Let number of small cups sold be (s) and a number of large cups sold be (l)
This forms a simultaneous equation below:
s + l = 155 ... (i)
1.25s + 2.5l = 265 ... (ii)
Multiplying (i) by 1.25 and (ii) by 1 we get:
1.25s + 1.25l = 193.75 ... (i)
1.25s + 2.5l = 265 ... (ii)
Subtracting (i) from (ii) we get:
0s + 1.25l = 71.25
1.25l = 71.25
l = 71.25 ÷ 1.25 = 57
So the number of large cups = 57 and;
the number of small cups = 155 - 57 = 98
