Answer:

Undeterminable to me

Step-by-step explanation:

Justin:180cm - 8cm per minute

Taylor:160cm + 6cm per minute

Doing the math, I could not determine the answer. So if there is an answer for "Never" or "No" I think it would be the answer

AlekseyPX

Answer:

20 ounces

Step-by-step explanation:

The line plot is attached below.

From the line plot, we can see that there is a total of 7 snack mix. Two of the snack mix weigh 1 and half (1.5) ounces each, one snack measure 2 and three quarter (2.75) ounce, three snack mix measure three and half (3.5) ounce each and one snack measure 3 and three quarter (3.75) ounce. Therefore the total weight of the snack mix is:

Total weight = (2 * 1.5) + (1 * 2.75) + (3 * 3.5) + (1 * 3.75)

Total weight = 20 ounces

Can someone help me solve this differentiation/tangent problem?

A)

\bf g'(x)=\stackrel{product~rule}{2x\cdot f(x)+x^2\cdot  f'(x)}\quad &#10;\begin{cases}&#10;x=5\\&#10;f(5)=5\\&#10;f'(5)=5&#10;\end{cases}&#10;\\\\\\&#10;g'(5)=2(5)\cdot f(5)+(5)^2\cdot f'(5)\implies g'(5)=50+500\\\\\\ g'(5)=550\\\\&#10;-------------------------------\\\\&#10;g(5)=(5)^2f(5)\implies g(5)=125&#10;\\\\\\&#10;\stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}&#10;\begin{cases}&#10;x=5\\&#10;y=125\\&#10;\stackrel{m}{g'(5)}=550&#10;\end{cases}\implies y-125=550(x-5)&#10;\\\\\\&#10;y-125=550x-2750\implies y=550x+400



b)

\bf h'(x)=\stackrel{quotient~rule}{\cfrac{f'(x)(x-6)~~-~~f(x)\cdot 1}{(x-6)^2}}\quad &#10;\begin{cases}&#10;x=5\\&#10;f(5)=5\\&#10;f'(5)=5&#10;\end{cases}&#10;\\\\\\&#10;h'(5)=\cfrac{f'(5)(5-6)~~-~~f(5)\cdot 1}{(5-6)^2}&#10;\\\\\\&#10;h'(5)=\cfrac{5(-1)-5}{(-1)^2}\implies h'(5)=-10\\\\&#10;-------------------------------\\\\

\bf h(5)=\cfrac{f(5)}{5-6}\implies h(5)=\cfrac{5}{-1}\implies h(5)=-5&#10;\\\\\\&#10;\stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\quad &#10;\begin{cases}&#10;x=5\\&#10;y=-5\\&#10;\stackrel{m}{-10}&#10;\end{cases}\implies y-(-5)=-10(x-5)&#10;\\\\\\&#10;y+5=-10x+50\implies y=-10x+45
