Answer:
see the procedure
Step-by-step explanation:
we have
where
c -----> the cost in dollars
g ----> the number gallons of gas purchased
1) For g=1 gal
substitute the value of g in the equation and solve for c
The pair (1,2.95) fit the relationship
2) For g=3 gal
substitute the value of g in the equation and solve for c
The pair (3,8.85) fit the relationship
3) For g=5 gal
substitute the value of g in the equation and solve for c
The pair (5,14.75) fit the relationship
4) For c=$20.65
substitute the value of c in the equation and solve for g
The pair (7,20.65) fit the relationship
Answer:
y = cot(x - ⅓π) + 2
Step-by-step explanation:
The general equation for a cotangent function with the given properties is
y = Acot(Bx + C) + D, where
A = the stretching factor
π/|B| = the period
C = the phase shift (negative is to the right)
D = the vertical shift
A = 1
π/|B| = π, so1/|B| = 1 and B = 1
C = -⅓π
D = 2
The function is
y = cot(x - ⅓π) + 2
The figure below shows the graph of the function with the given parameters.
Note that the parent function y = cot(x) has the y-axis as an asymptote, so we can measure the phase shift by the movement of the asymptote π units to the right.
Answer:
49°
Step-by-step explanation:
First, solve for x.
3x-7+2x+17=90
5x+10=90
5x=80
x=16
Then put 16 in for x.
2(16)+17=
32+17=49

Answer:He buys 8 pounds
Step-by-step explanation:
You can either just add up the $3.25 until you get to the end-price, but that wont always work for every problem. The best way is to divide the 26 with the 3.25 in a written devision.
