Answer:
y = -16x² +180
Step-by-step explanation:
The vertex appears to be the high point of the graph, (0, 180). Then the vertex form equation is ...
y = a(x -0)² +180
The value of 'a' can be found using the other given point. Substituting for x and y, we have ...
164 = a(1 -0)² +180
-16 = a
Then the complete simplified vertex form equation is ...
y = -16x² +180
Answer:
The area is 15 feet
Step-by-step explanation:
So you are going to need two different equations-
l = w(3)
2l + 2w = 40
Insert the first equation into the second-
2(3w) + 2w = 40
Simplify this equation-
6w + 2w = 40
8w = 40
Divide both sides by 5
w = 5
Solve first equation
l = 5(3)
l = 15
Then find the area-
5 x 15 = 75
Answer:
The formula for the volume of a prism is V = Bh
where,
B is the base area
h is the height.
Since, the base of the prism is a rectangle, therefore, volume of a rectangular prism = (L * B) * h
Assumptions:
Length, L and Width, B cannot be the same.
1.
h = 4 ft
B = 2 ft
L = 9 ft
2.
h = 4 ft
B = 3 ft
L = 6 ft
3.
h = 6 ft
B = 2 ft
L = 6 ft
4.
h = 2 ft
B = 2 ft
L = 18 ft

Answer:
30 hours.
Step-by-step explanation:
Richard can build 15 snowballs in 1 hour
But 2 snowballs melt every 15 minutes
In 1 hour, the number of snowballs that will have melted is:
× 2 = 8
The number of snowballs that will have remained = 15 - 8 = 7
So 7 snowballs will have remained in 1 hour
For 210 snowballs to have remained, it will take:
× 1 = 30 hours.
