Answer:
It is not a function.
Step-by-step explanation:
This is what we call a mapping;
Functions do not give multiple output values for a given input value;
As we can see, the input 2 produces an output of 20 and 40, therefore we can tell this is not a function.
Answer:
She deposits $350 into the account at the beginning of the year.
Step-by-step explanation:
Let us assume that Keegan deposits $P into her savings account at the beginning of the year.
The account earns 3% simple interest each year and she has $360.50 in her account at the end of the year.
If Keegan did not make any additional deposits or withdrawals during the year.
So, we can write that ![P[1+\frac{3}{100} ]= 360.50](https://tex.z-dn.net/?f=P%5B1%2B%5Cfrac%7B3%7D%7B100%7D%20%5D%3D%20360.50)
⇒ P = $350 (Answer)
You can use the Pythagorean Theorem. Which is a^2 + b^2 = c^2.
So now to plug in the equation.
In your case a is 8 and c is 34. So now we need to solve for b.
8 squared is equal to 64.
34 squared is equal to 1156.
Now to plug things in.
64 + b^2 = 1156
Now subtract 64 from 1156.
That equals 1092.
The equation is now
b^2 = 1092
Now do the square root of 1092.
But since the square root is an irrational number you can just write b = 1092 ( but put a square root with 1092)
So there’s a flat fee of 2 and that’s like a standalone thing so our equation would be
2 + 1.50m
Assuming m = 9, it would be 2 + 13.50
And the two answers are-
A) $15.50
B) 2 + 1.50m
Answer:
25, right, 5, 3, 4,
Step-by-step explanation:
5^2 = 5*5 = 25
the triangle has a right angle and is therefore a right triangle,
the sides of the squares that make up the triangle are length 5, length 3, and length 4
