What is the maximum vertical distance between the line y = x + 20 and the parabola y = x2 for −4 ≤ x ≤ 5?

Fofino [41]

The vertical distance can be found by subtracting parabola from the given line.

Given line equation is y= x+20

Equation of parabola is y= x^2

Subtract parabola from line equation

so y = $x+20 -x^2$

y = $-x^2 + x + 20$

Now we take derivative to find out the maximum that is the vertex

y' = -2x + 1

Now we set derivative =0 and solve for x

0 = -2x+1

2x = 1

$x=\frac{1}{2}$

Now we plug in x values in $y= -x^2 + x + 20$

$y = (\frac{1}{2}^2) + \frac{1}{2} + 20$

Take common denominator

$y= \frac{81}{4}$

So our maximum vertical distance is $\frac{81}{4}$ at $x= \frac{1}{2}$

. Find the current assets of a clothing store that has $62,300.00 in cash, $1,200.00 in accounts receivable, and $26,548.00 in m

Alex

Current assets is the sum of cash in hand, accounts receivable, and merchandise.

So we need to find the sum of all the figures given in the question.

Current assets = Cash in hand + Accounts receivable + Merchandise

Current assets = $62,300 + $1200 + $26,548 = $90,048

So $90,048 is the final answer.
