Trapezium A is the trapezium you start with. And then you are expected to reflect it on the y axis (which is just the vertical line x=0)
When you say "at the same ratio", you mean that you consume the same amount of gas for the same amount of miles.
We know that everytime you drive 75 miles, you use 3 gallons of gas.
Since 12 gallons of gas is four times 3 gallons of gas, if the ratio remains the same, you can drive four times the distance:
You drive 75 miles, and use 3 gallons.
You drive 75 more miles (so you are at
miles) and use 3 more gallons, so you use
gallons.
You drive 75 more miles (so you are at
miles) and use 3 more gallons, so you use
gallons.
You drive 75 more miles (so you are at
miles) and use 3 more gallons, so you use
gallons, and you're done.
Answer:
V = 904.32cm3
Step-by-step explanation:
V = r*r*pi*h
= 6*6*3.14*8 = 904.32cm3
We know that area=0.5*base*height.
Thus, the equation would look like:
127.5=0.5*base*height
That means, 255 = base*height.
We know base is 17
Then, we divide 255 by 17. That gets us the height.
The height equals 15.
The y-intercept occurs on a graph when x = 0. Therefore on a graph of y= ab^x when x = 0, y = ab^0 = 1. Therefore the y-intercept is at the point (0,1).
Hope this helps!
