Answer:
Step-by-step explanation:
When x=0, y = ab⁰ = a
The y-intercept of the graph is 3, so a=3.
<em>Ohhh, interest problems. I haven't done an equation like this in a long time, but I will attempt.</em>
<em>I would say that the answer is the 2nd option. The equation is i = (5200)(0.06)(2.5).</em>
<em>The traditional interest formula is I = (P)(R)(N).</em>
<em>P = the original amount of money given</em>
<em>R = interest rate</em>
<em>N = the amount of time</em>

Answer:
the first one from the top
When Peter does this, he is creating two sides of a right-angle triangle. The distance from his house to that point will be the hypotenuse of the triangle thus, to work out the length of the hypotenuse, we have to use Pythagoras Theorem! So:
a² + b² = c²
15² + 15² = c²
225 + 225 = c²
450 = c²
15√2 = c
21.21320344 = c
So, this rounded to the nearest tenth would be:
21.2 meters !
Answer: E: The number of books a person finished reading last month
Step-by-step explanation:
First, a discrete variable is a variable that only can take some given values in a set, the discrete variables are usually not dense, and a continuous variable is a variable that can take any value in a range (where the accepted values are dense).
So, for example, the set of the natural numbers is discrete, and the set of the real numbers can represent a continuous variable.
Here the only option that is really discrete will be the number of books that a person finished reading last month because here only positive whole numbers are accepted (you can not finish a 0.454 of a book)
The other options are continuous because all are classical measures.
For example, the weight of a person can jump between:
75.6kg and 75.7kg.
So you could think that this is discrete because the values between 75.6kg and 75.7g are not shown with our measuring device, but those will be added in the error of the measure because the weights between 75.6kg and 75.7kg are actually possible, so they must be accepted.
