If f(x) = (5x^3 - 4)^4, then what is f '(x)?
vlabodo [156]
You apply the rule to put the exponent in front, and lower it by one. But since this is a nested expression, you apply it twice:

4*(5x^3-4)^3 * 3*5x^2 =

60x^2 (5x^3-4)^3

Mei Mei left her house at time zero and drove for 4 minutes to the store, at a speed of 2 blocks per minute. Then she stopped an
m_a_m_a [10]

The graph for Mei Mei' trip is attached accordingly. Also attached are the  values derived from the question.

<h3>What is the explanation for the graph?</h3>

The secret to comprehending the graph is to understand that every time Mei Mei spent while she was on the way to bank and back were are all computed cumulatively.

This means that when she stops at the store which is 8 blocks away from home (that is 2 blocks per min x 4 mins = 8blocks) the time spent is recorded as 4 + 5 at location 8 blocks, which is equals 9 minutes.

Also take note of the fact that the time spent is plotted on the x-axis and the blocks away from home on the y-axis.

John is 6 years older than Keisha. Together, their ages equal four times Keisha's age. How old is each? (Note: There must be an
borishaifa [10]
<span>k= Keisha  
k + 6= John</span> <span>         
k + k + 6 =  4k</span> <span>  
2k + 6 ( - 2k) =  4k ( - 2k)</span> <span>              
6 = 2k</span> <span>           
3 = k    
(Keisha= 3 years old)</span> <span>         
k + 6 = 9    
(John = 9 years old)
</span>
3 + 3 + 6 = 4 (3) <span>         
12 = 12

</span><span>So we made the pawn represent Keisha’s age.  Then we knew that John is 6 years older than Keisha so we represented his age with a pawn plus 6. This went on 1 side of the equation because it said that together they equal 4 times Keisha’s age. So on the other side of the equation we put 4 pawns because we are using each pawn as Keisha’s age.  Then we subtracted the pawns from each side to keep the equation balanced.  So we had that 2 pawns equal 6, which means that each pawn equals 3 so Keisha is 3 years old.  Since John is 6 years older than Keisha, he must be 9 years old.  We checked our work and substituted 6 in for each pawn and found that 12 equals 12, so our equation is balanced.
