Answer:
x ≈ 8.1233
Step-by-step explanation:
SOH CAH TOA<em>(tangent = </em><em>opposite/adjacent side</em><em>)</em>
tan (32) = x/13
=> x = tan (32) × 13
=> x ≈ 8.1233
There are 12 inches in a foot, so just divide the number of inches (108) by 12 to get the number of feet.
108 / 12 = 9
So Marcus needs 9 feet of wood.
Answer:
B
Step-by-step explanation:
The domain goes from -4 to 9. It would not be brackets since the actual points are not on the graph so it would be parentheses.
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)
= 
(g·f)(x)= g(x) × f(x)
= (-x) × (x³+x+1)
= 
Therefore, the value of (f· g)(x) from the given functions is
.
