Answer:
Initial value 
, rate of change: 
Step-by-step explanation:
Step 1
Find the rate of change
we know that
In a linear equation the rate of change is equal to the slope
The formula to calculate the slope between two points is equal to
we have
Substitute the values
----> rate of change
Step 2
Find the initial value
The equation of the line into slope-point form is equal to
Substitute
The initial value is the value of y when the value of x is equal to zero (is the y-intercept)
----> initial value
Answer: 50 cubic feet
Explanation:
Volume= length•width•height
V = 5ft • 2ft • 5ft = 50
V= 50 cubic feet
Answer:
5/6
Step-by-step explanation:
Perpendicular lines just have the opposite slope.
38 yard piece for each student and there are 16 students:
38*16=608
608 yards needed for your class
4, 7, 12, 19, 28
1st difference +3 +5 +7 +9
2nd difference +2 +2 +2
This is a geometric sequence
The form is:
an² + bn + c
2a is always = to the second difference
2a = 2
a = 1
3a + b = 2nd term - 1st term
3(1) + b = 3
3 + b = 3
b = 0
a + b + c = 1st term
1 + 0 + c = 4
1 +c = 4
c = 3
nth term of sequence {substitute all we have found}
1n² + 0 + 3
n² + 3
