Answer:
![(f\circ g)(4)=31](https://tex.z-dn.net/?f=%28f%5Ccirc%20g%29%284%29%3D31)
Step-by-step explanation:
<u>Composite Function</u>
Given f(x) and g(x) real functions, the composite function named fog(x) is defined as:
![(f\circ g)(x)=f(g(x))](https://tex.z-dn.net/?f=%28f%5Ccirc%20g%29%28x%29%3Df%28g%28x%29%29)
For practical purposes, it can be found by substituting g into f.
We have:
![f(x)=3x+1](https://tex.z-dn.net/?f=f%28x%29%3D3x%2B1)
![g(x)=x^2-6](https://tex.z-dn.net/?f=g%28x%29%3Dx%5E2-6)
Computing the composite function:
![(f\circ g)(x)=f(g(x))=3(x^2-6)+1](https://tex.z-dn.net/?f=%28f%5Ccirc%20g%29%28x%29%3Df%28g%28x%29%29%3D3%28x%5E2-6%29%2B1)
Operating:
![(f\circ g)(x)=3x^2-18+1](https://tex.z-dn.net/?f=%28f%5Ccirc%20g%29%28x%29%3D3x%5E2-18%2B1)
Operating:
![(f\circ g)(x)=3x^2-17](https://tex.z-dn.net/?f=%28f%5Ccirc%20g%29%28x%29%3D3x%5E2-17)
Now evaluate for x=4
![(f\circ g)(4)=3(4)^2-17=48-17](https://tex.z-dn.net/?f=%28f%5Ccirc%20g%29%284%29%3D3%284%29%5E2-17%3D48-17)
![\boxed{(f\circ g)(4)=31}](https://tex.z-dn.net/?f=%5Cboxed%7B%28f%5Ccirc%20g%29%284%29%3D31%7D)
Total number of computers sold last week from Best Bargain = 340
Percentage of laptops sold last week from Best Bargain = 75%
These are the information's that we can find given in the question. Based on these information's the answer to the question can be easily found.
Number of laptops sold from Best Bargain last week = 340 * (75/100)
= 340 * (3/4)
= 85 * 3
= 255
So out of the total of 340 computers sold from Best Bargain last week, 255 were laptops. I hope this is the answer you were looking for.
Answer:
your school got me lost what grade you in
Answer:
A
Step-by-step explanation:
he actually made a mistake in second step. Step 2 should be: 10y-2=18 and then 10y=18+2
we get 10y=20 /:10
y = 2
Note:
sin(-θ) = -sinθ
sin(-15°) = -sin15° Use a calculator
sin(-15°) = -sin15° = -0.2588
sin(-15°) = -0.2588
