The gradient of the function is constant s the independent variable (x) varies The graph passes through the origin. That is to say when x = 0, y = 0. Clearly A and D pass through the origin, and the gradient is constant because they are linear functions, so they are direct variations. The graph of 1/x does not have a constant gradient, so any stretch of this graph (to y = k/x for some constant k) will similarly not be direct variation. Indeed there is a special name for this function, inverse proportion/variation. It appears both B and C are inverse proportion, however if I interpret B as y = (2/5)x instead, it is actually linear. I believe the answer is C. Hope I helped!
The answer to that would be 2.25 An easy calculator on your phone can also solve that if you didn’t know :)
It would be about 3.5 miles long so you chose 3 miles or 4 miles i would go with (4 miles)
Answer:
m=3, n=5
Step-by-step explanation:
(3+√5)² = (3+√5)(3+√5) =
3² + 3√5 + 3√5 + √5·√5 = 9 + 6√5 + 5 = 14+6√5
Answer:
She is actually paying a rate of 7.36% of interest.
Step-by-step explanation:
The real interest rate, as a decimal, is given by:
In which r is the interest rate and n is the number of compoundings during an year.
The nominal rate on Sandra's loan is 7.125%, compounded monthly:
This means that 
So
As a percentage: 1.0736*100 = 107.36% - 100% = 7.36%
She is actually paying a rate of 7.36% of interest.
