Answer:
Step-by-step explanation:
The question should be :
A solid right pyramid has a square base with an edge length of s units and a height of h units.
The formula for the volume of the pyramid is given by :
A is area of base and h is height.
As edge length is s units.
A = (s)²
So,
So, the required volume is one-thirds s²h unit³.
Answer:
The number of completed weeks when Natasha and Taylor will have an equal amount of saved is 8 weeks
Step-by-step explanation:
The starting amount of Taylor's savings = $10
The amount Taylor plans to save a week = $20
Therefore, the function that models Natasha's saving plan is y = 10 + 20·x
The function that models Natasha's saving plan is y = 50 + 15·x
Where;
y is the amount in savings
x is the number of completed weeks
When the amount of savings, y, of both Natasha and Taylor are equal, we have;
y for Natasha = y for Taylor
Therefore
10 + 20·x = 50 + 15·x
20·x - 15·x = 50 - 10
5·x = 40
x = 40/5 = 8
The number of completed weeks when Natasha and Taylor will have an equal amount of saved, x = 8 weeks
Answer:
2nd equation does not pass the vertical line test
(7,9) (7,3) (x,y)
because one x (input) should have one y (output)
however, one y (output) can have multiple x (inputs)
