Portia is a designer working on creating plans for the city of Geocove's new waterpark. The graph shows her plan for a waterslide for young children. The equation that represents this line is y = -1/3x + 4. The x-axis represents the ground, and the y-axis represents one of the poles that will support the slide.Each unit on each axis represents 1 foot. Suppose that a rider coming down this slide has a horizontal change of 6 feet. What is the value of their vertical change? Explain.

Answers

$y=\stackrel{\stackrel{m}{\downarrow }}{-\cfrac{1}{3}}x+4\qquad \impliedby \qquad \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\n \cline{1-1} \n y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \n\n \cline{1-1} \end{array} \n\n[-0.35em] ~\dotfill$

$slope=\cfrac{\stackrel{\textit{vertical change}}{Rise}}{\underset{\textit{horizontal change}}{Run}}\hspace{5em} slope=\cfrac{\stackrel{\textit{vertical change}}{1}}{\underset{\textit{horizontal change}}{3}} \n\n\n \stackrel{ \textit{when the Run = 6, what's the Rise?} }{\stackrel{slope}{\cfrac{1}{3}}=\cfrac{\stackrel{\textit{vertical change}}{v}}{\underset{\textit{horizontal change}}{6}}}\implies \cfrac{1}{3}=\cfrac{v}{6}\implies \cfrac{6}{3}=v\implies \boxed{2=v}$

in this case the slope is -1/3, the negative part simply means the slope is going down from left-to-right, as it'd be the case in a waterslide.

Answer:

Vertical change is 2 feet.

Step-by-step explanation:

The equation of the line is $\sf y = -(1)/(3)x + 4.$

This equation can be rewritten as : $\sf y -4 = -(1)/(3)x$

If a rider coming down this slide has a horizontal change of 6 feet, then their x-coordinate will change by 6.

This means that their new x-coordinate will be 6.

We can now plug this value of x into the equation for y to find their new y-coordinate.

$\sf \sf y -4 = -(1)/(3)* 6$

$\sf y - 4 = -2$

Adding 4 on both sides

$\sf y -4+4 =-2+4$

$\sf y = 2$

Therefore, the value of their vertical change is 2 feet.

In other words, if a rider starts at the point (0, 4) on the graph, and they move 6 units to the right, they will end up at the point (6, 2).

The vertical change is 4 - 2 = 2 feet.

What's 2.85 tons rounded to the nearest hundredth

Answers

I think its 2.90 because the hundreth is the second to the right and its a five so it goes up to 90

2.85 tons. The hundredth spot is the second one to the right of the decimal (the 5) and since that's where you're rounding to it stays 2.85 tons :)

at 3:00 am, the temperature was -13 degrees. in alaska. At 10:00 am, the temperature was 22 degrees, what was the average change in temperature per hour?

Answers

If you go from -13 to 0, you have an increase of 13 degrees. Then if you go from 0 to 22 you have an increase of 22 degrees. 13 + 22 = 35.
3:00 am to 10:00 am is 7 hours so:
35 degrees/7 hours = 5 degrees/hour
Also english is my second langauge so sorry if it's hard to understand

So, there is a 7 hour span. There is 35 degree change total. So solve. Take 37/7=5
5 is the average
