Answer: 40
Step-by-step explanation:
Answer:
c = 5
Step-by-step explanation:
We can find a, b, c by filling in values from the table into the equation:
17 = a(2²) +b(2) +c
32 = a(3²) +b(3) +c
53 = a(4²) +b(4) +c
__
There are numerous ways to solve 3 linear equations in 3 unknowns. We can use elimination.
Subtracting the first equation from each of the other two, we get ...
15 = 5a +b . . . . . . . . . note that c has been eliminated from the equations
36 = 12a +2b
Subtracting twice the first from the second gives ...
(12a +2b) -2(5a +b) = 36 -2(15)
2a = 6
a = 3
__
Now that we have a value for "a", we can "back substitute" into the equations to find "b" and "c".
Substituting this into 15 = ..., we get ...
15 = 5(3) +b
0 = b
And substituting for "a" and "b" in the first original equation gives ...
17 = 4(3) +c
5 = c
The value of c, the constant of the function, is 5.
Since the workouts are normally on hour scale, thus the first comparison of $9.00 per hour of childcare is more appropriate here.
<h2>Given that:</h2>
- Gym A charges $9.00 per hour of childcare.
- Gym B charges $0.75 per 5 minutes of childcare
<h2>How to find which scale is appropriate when?</h2>
Firstly try to find what is the usual scale used for that work.
The usual scale used for given specified work is mostly the appropriate scale.
For Gym case, people are not coming and going in minutes scale, but they count in hours and will be able to comprehend the hour scale better.
Both Gym although offer same price (since $0.75 per minute is equal to $9.00 per hour), but the cost Gym A specifies is more easy to understand for normal public, thus it is more appropriate scale.

Answer:
17.16
Step-by-step explanation:
So if the area of the rectangle is 8.8*3.9=34.32, L*W=H, then the triangle which has the same length and width, would have L*W*1/2. If you fill in the variables, then you would get 8.8*3.9*1/2=17.16. You can do this on any calculator, and please put my answer as the brainliest.✌
