Question #2
Erica will have to work for 14 hours in order to buy her sneakers.
How to solve:
You subtract $31 from $150 which equals to $119
You multiply 8.50 (which is the amount of money she gets paid every hour) by the answers they gave you.
8.50 multiplied by 14 is 199
Erica had to work 14 hours to make $199
Your answer is D) 14
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 .

It took Mark 2 1/2 hours to cycle 25 miles. 2 hours 30 minutes or 150 minutes.
Answer:
The distance from his starting point is <u>6.7 m</u>.
Step-by-step explanation:
Given:
Shane marched 3 m East and 6 m north.
Now, to get the distance from his starting point.
Let the distance from the starting point be
Now, to solve using pythagorean theorem:
<em>Using square root on both sides we get:</em>
<u>So, the distance from the starting point nearest to tenth is 6.7 m.</u>
Therefore, he is 6.7 m from his starting point.
