Find (f ° g)(0). *

Mathematics
1 answer:
atroni [7]2 years ago
8 0

Answer:

B

Step-by-step explanation:

Remark

I have to represent f(x) as plus +f(x)

I like to show this situation as +f(g(x)) which I think is much clearer.

+f(x) = 5x - 4    

Solution

+f(g(x)) = 5(g(x)) - 4  What has happened is that wherever you see an x on the right you put in g(x).

Now on the right, you put whatever g(x) is equal  to.

+f(g(x)) = 5(x^2 - 1)  - 4    

Remove the brackets.

+f(g(x)) = 5x^2 - 5 - 4

And make x = 0

+f(g(0)) = 5*0 - 5 - 4

+f(g(0)) = - 9

Find the area of the triangle.
Vsevolod [243]

Answer:

20 m²

Step-by-step explanation:

<u>Formula (Area of triangle):</u>

<u />\text{A (Triangle)} = \dfrac{1}{2}  \times \text{Base} \times \text{Height}

From the triangle, we can see that the base of the triangle is "7 + 3" m and the height of the triangle is "4" m.

<u />\implies \text{A (Triangle)} = \dfrac{1}{2}  \times (7 + 3) \times (4)

Simplify the right-hand-side as needed to evaluate the area.

<u />\implies \text{A (Triangle)} = \dfrac{1}{2}  \times (10) \times (4)

<u />\implies \text{A (Triangle)} = \dfrac{40}{2}  = 20 \ \text{m}^{2}

Therefore, the area of the provided triangle is 20 m².
