Answer: 10 miles
Step-by-step explanation:
Practically, just look at it. 30 minutes = 5 miles, 60 minutes = 10 miles
Mathmatically, find the constant of proportionality.
- 30 minutes divided by 5 miles = 6 minutes per 1 mile.
- 60 minutes = 10 miles
Step-by-step explanation:
M=NPQ
m/pq=Npq/pq
pq is going to cancel, you left with N
N= m/pq
To solve for q, we have to make q the subject.
m = Npq
divide both sides of the equation by NP
M/NP= q
that's the answer
Answer:
$2.23
Step-by-step explanation:
30 - 3.24 = 26.76
26.76 ÷ 12 = 2.23
Plug in points to general form of quadratic function:
y=ax²+bx+c
(0,7)
7 = c
(2,13)
13 = 4a +2b + c
(4,3)
3 = 16a + 4b + c
Now solve the system of equations in two unknowns.
Substitute the value of 7 for c in the second equation:
13 = 4a + 2b + 7
6 = 4a + 2b
3 = 2a + b
b = 3 - 2a
Substitute this into third equation:
3 = 16a + 4(3-2a) + 7
3 = 16a + 12 - 8a + 7
3 = 8a + 19
-16 = 8a
a = -2
b = 3-2a = 3 - 2(-2) = 7
a = -2, b =7. c = 7
The quadratic function is y= -2x² + 7x +7
