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.
Answer:
1. Rotation
2. Reflection
3. Translation
Explanation:
1. Rotate figure A to the right it would match figure B
2. Imagine folding figure A down it would match figure B
3. Move figure A down and right and it would match figure B
Slope = -1
and it goes through (1, -7)
Answer:
Rate = 10%
Step-by-step explanation:
We are given with the following details.
Interest earned = $ 116.25
Principal = $ 1550
Interest Rate = r (say)
Time = 9 months
= 
We are asked to determine the rate of interest for which we can earn 116.25 interest. As we are not specifically given whether it is a compound or simple interest , we assume it to be simple interest and solve .
The formula for simple interest is given as
r=0.1
Hence the r = 0.1
Hence the rate of interest is 10%
Answer:
61/70
Hello everyone my name is Nevaeh, I know everyone needs help in some way, shape, or form and i am willing to provide. I set up a google classroom where people can ask me questions and get help on work. No question is a stupid question so do not be afraid to ask.
