Answer:
22.5 ![m^{2}](https://tex.z-dn.net/?f=m%5E%7B2%7D)
Explanation:
The equation for the area of a triangle is
bh
In this case, the base is 9 m and the height is 5 m
9x5=45
45/2= 22.5
The value of (f· g)(x) from the given functions is
.
The given functions are f(x)=x³+x+1 and g(x)=-x.
<h3>What is the function?</h3>
Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
Here,
(f·g)(x)= f(x) × g(x)
= (x³+x+1) × (-x)
= ![-x^4-x^2-x](https://tex.z-dn.net/?f=-x%5E4-x%5E2-x)
(g·f)(x)= g(x) × f(x)
= (-x) × (x³+x+1)
= ![-x^4-x^2-x](https://tex.z-dn.net/?f=-x%5E4-x%5E2-x)
Therefore, the value of (f· g)(x) from the given functions is
.

645/8= 80.625 lol why do u even need this
<span>Not included first digit (6), there are 7 digits so
62 500 000 = 6.25×10^7</span>
