Answer:
- 13
Step-by-step explanation:
To evaluate (g ○ f)(3), evaluate f(3) then use this value to evaluate g(x)
f(3) = 3 - 7 = - 4, then
g(- 4) = 4(- 4) + 3 = - 16 + 3 = - 13
When you're dividing fractions, you've got to slip the second fraction then multiply them together. Once you've flipped it, you get
5/6 x 7/3
You then simply multiply the numerators and the denominators
5x7= 35
6x3= 18
Therefore, this becomes 35/18, which can be simplified to 1 17/18
Hope this helps :)
Answer:
0 ≤ c ≤ 42
Step-by-step explanation:
The cost to take a car across a bay on a ferry is $16.
The ferry has a capacity of 42 cars.
Now, given that the revenue collected is a function of the number of cars, c.
R(c) = 16c .......... (1)
As the maximum capacity of the ferry is 42 and the number of cars can not be negative but can be zero.
So, the domain of the function (1) will be 0 ≤ c ≤ 42 (Answer)
Answer:
Length = 208in
width=160in
Area=33280in²
Step-by-step explanation:
8ft is equal to 96inches thus ratio is 3:96
length= 6.5×96/3
=208in.
width=5×96/3
=160in.
Area=l×w
=208×206
=33280in²
That is a direct division, if you are confused by the decimal point, lets get rid of it! We can get rid of the decimal point multiplying the upper and lower parts of the division by 10, lets do it:
<span>62.8 / 3
= 10*</span><span>62.8 / 10*3
= </span><span>628 / 30
we can try to reduce the fraction dividing by 2 the upper and lower parts:
= 314/15
and now we have to make the operation:
= 20.93</span>
