Its basically the order. The first one is b divided by 10, whereas the second is 10 divided by b. If b was 2, the first one would be .2, where the second one would be 5.
Answer:
d = 711 miles
Step-by-step explanation:
The speed s of the car is given by :
...(1)
Where
d is the stopping distance
We need to find the stopping distance of a car travelling at 80 mph.
Rearranging equation (1) for d.
or
d = 711 miles
So, the required stopping distance is 711 miles.
Answer:
<h2>170</h2>
Step-by-step explanation:
given:
Ann, Ben, and Cindy were eating strawberries.
The ratio of the numbers of berries they ate is 5:5:7.
If Cindy ate 30 strawberries less than Ann and Ben together,
find:
what is the total number of strawberries the three of them ate?
solution:
add the ratios 5 + 5 + 7 = 17
since Cindy ate 30, less than Ann and Ben together so, the equation is
7x = 5x + 5x - 30
7x - 10x = -30
x = 30/3
x = 10
ann 5 x 10 = 50
ben 5 x 10 = 50
<u>cindy 7 x 10 = 70
</u>
total = 170
Answer:
The required function is:
Step-by-step explanation:
The weight of the baby increases 2lbs per month which means that it is a linear function.
Now given that the initial weight was 8lbs it will remain constant.
Let t be the number of months and as the weight gain is 2 lbs per month, 2t will be the weight gain after t months.
The function can be written as:
Hence,
The required function is:
Answer:
- x^3 -2x^2 + 2x -2
- c(2) = - 4
Step-by-step explanation:
<u>Given</u>
- f(x)=2x^3 - 4x^2 + 2
- g(x)=x^3 - 2x^2 - 2x + 4
<u>To find</u>
<u>Solution</u>
- f(x)-g(x)=
- 2x^3 - 4x^2 + 2 - (x^3 - 2x^2 - 2x + 4) =
- 2x^3 - 4x^2 + 2 - x^3 + 2x^2 + 2x - 4 =
- x^3 -2x^2 + 2x -2
==================
- c(x) = -2x
- c(2) = -2*2 = - 4
