Answer
C. The relationship is proportional with the point (1,60) representing the unit rate.
Explanation
Let’s say 2 variables are x and y
Now give those 2 variables names
x = number of trainers sold
y = profit
A proportional relationship is one where 2 variables are related by some constant k
e.g y = kx
As x increases so does y. So as more trainers are sold more profit is made.
If there is no relationship the points will be scattered in the diagram however here they have a perfect linear relationship.
Unit rate, is the rate that the y variable increases as the x variable increases by 1.
Which in this instance is 60 for every 1 increase in x value.

Answer:
He was faster the second time around.
Step-by-step explanation:
Since 1/10 is more than 1/12, he spent less time the second time than he did the first, meaning that he typed faster in the second attempt than the first.
Consider the following expanded powers of (a + b)n, where a + b is any binomial and n is a whole number. Look for patterns.
Each expansion is a polynomial. There are some patterns to be noted.
1. There is one more term than the power of the exponent, n. That is, there are terms in the expansion of (a + b)n.
2. In each term, the sum of the exponents is n, the power to which the binomial is raised.
3. The exponents of a start with n, the power of the binomial, and decrease to 0. The last term has no factor of a. The first term has no factor of b, so powers of b start with 0 and increase to n.
4. The coefficients start at 1 and increase through certain values about "half"-way and then decrease through these same values back to 1.
The required vertex form of the given equation is a) is correct
the function is given,
<h3>What is vertex form?</h3>
vertex form of a equation is given by .
since
Now h = - b/2a
h = -N
Now at x = 0
k = 10
vector form can be given by
