Jane is organizing a fundraiser to buy a ping-pong table for the community center. The table costs $500.00. Jane is asking contr

kogti [31]

Answer:

Function: C = 500 / n

Jane must recruit 20 more contributors or 25 contributors in total for the cost of each share to be $20.

Step-by-step explanation:

1. Cost per share, C, with respect to the number of contributors, n is

C = 500 / n

So, with 5 contributors, the price is $100 per share. $100 = 500/5

2. C= $20

20= 500 / n

20 * n = 500 * n

20n = 500

n= 25

She already has 5 contributors, so she needs 20 more.

Ryan and Marie had some marbles. if Ryan lost `15 marbles, he would have 4 times as many marbles as Marie. If Ryan lost 75 marbl

vaieri [72.5K]

Ryan's marbles = x
Marie has 4 times less marbles then Ryan would have if he lost 15 marbles (it means he would have x-15)
So, Marie marbles = (x-15):4
If Ryan lost 75 marbles (it means he would have x-75), he would have 1 1/2 times as many marbles as Marie.

We got an equation: $x-75=1\frac{1}2\cdot\frac{x-15}{4}$

          $x-75=\frac{3}2\cdot\frac{x-15}{4}$

Multiply both sides by 8:     $8x-8\cdot75=3\cdot(x-15)$

      $8x-600=3x-45$

Add 600 and subtract 3x on both sides:    $5x=555$

Divide both sides by 5:    $x=111$

Answer: Ryan have 111 marbles.

Finding an Equation of a Tangent Line In Exercise, find an equation of the tangent line to the graph of the function at the give

devlian [24]

Answer: y = 2.5(x-1)

Step-by-step explanation:

Step 1

Find the point of tangency.

It's given as (x,y)= (1,0)

Step 2

Find the first derivative, and evaluate it at x=1

f'(x) = 5/2 × d(lnx)/dx = 5/2 × 1/x = 5/2x

f'(x) = 5/2 = 2.5

The slope of the tangent line at this point is m= 2.5

Step 3

Find the equation of the tangent line at (1,0) with a slope of m=2.5

y−y1 = m(x - x1)

y-0 = 2.5(x-1)

y = 2.5(x-1)
