The graph shows the volume of oil (L litres) in a tank at time t seconds. a)find the gradient of the graph b)explain what this g

Alisiya [41]

Answer/Step-by-step explanation:

a. Using two points on the line (0, 2) and (4, 12), find the gradient:

Gradient = ∆y/∆x = (12 - 2) / (4 - 0) = 10/4 = 2.5

Gradient = 2.5

b. The gradient, 2.5, represents the unit rate. That is, the volume of the oil in the tank per second.

i.e. 2.5 litres per second

c. The value, L = 2 represents the y-intercept, which is the starting value or initial volume of oil in the tank at 0 secs.

What is the slope of the line that passes through the points (-9,0) and (-17 , 0 )

marishachu [46]

Answer:

$\mathrm{Slope=== > 0}$

Step-by-step explanation:

Hi student, let me help you out!

<u>.............................................................................................................</u>

<u></u>

First, let's recall the slope formula: $\boxed{\mathrm{\cfrac{y2-y1}{x2-x1}}}}$ , where y2 and y1 are y-coordinates; x2 and x1 are x-coordinates.

Plugin the values: $\mathrm{\cfrac{0-0}{-17-(-9)}}$ .

Upon simplifying, we obtain $\mathrm{\cfrac{0}{-17+9}}$ .

Upon simplifying this further, we obtain $\mathrm{\cfrac{0}{-9}}$ .

0 divided by anything results in 0.

✨ ∴, the slope of this particular line is 0, and this line looks something like this: $\rule{200}{1}$ .

See, it's a horizontal line, with a rise of 0, meaning that it goes up 0 units.

Hope this helped you out! Ask in comments if even the slightest queries arise.

Best Wishes!

Find the output of the function y = x - 16 if the input is -28.<br> Help please

Serhud [2]

Answer:

-44

Step-by-step explanation:

If the input is -28, that means x = -28, so we plug -28 in for x and solve for y, which is the output:

y = x - 16

y = -28 - 16 = -44

The answer is thus -44.
