Answer:
no, they are not functions
Step-by-step explanation:
this is because a single domain has multiple range.
i.e. domain 2 has ranges 2 and 4
Hi there!
To find the median, list all the numbers in a least to greatest order then find the number in the middle. If there is an even number of numbers, find the mean (average) between the two numbers in the middle.
You are given 107, 114, 214, 230, 436, and 445. They are already in order from least to greatest. There is an even number of numbers (6), so find the two numbers in the middle.
214 and 230
Now find the mean between these numbers. To find the mean, add up both the numbers then divide by how many numbers you added up (2).
214 + 230 = 444
444 ÷ 2 = 222
The mean of the two numbers in the middle is 222. The median distance driven in the data is 222 miles.
Hope this helps!
Answer: 15.2
Step-by-step explanation:
(14)^2 + (6)^2 = c^2
196 + 36 = c^2
232 = c^2
Square root both sides
15.231546 = c
15.2 ≈ c
Thank you for posting the figure. Without it, I would have thought the parabola has a vertical axis.
For a parabola with a horizontal axis (as in this case), the equation of the parabola is
f(y)=a(y-k)^2+h
where (h,k) is the vertex.
Substituting (h,k)=(2,-4),
f(y)=a(y+4)^2+2...................(1)
as the equation of the parabola, with the value of "a" yet unknown.
Since we are given that the parabola passes through the point (-3,-3), we can substitute the corresponding x,y values in (1) to solve for a.
f(y)=-3=a(-3+4)^2+2
solve for a
a=(-3-2)/(1^2)=-5
So the equation of the parabola is f(y)=-5(y+4)^2+2
Answer:
40
Step-by-step explanation:
You would first want to plug in.
10 x (-1)² x (-2)²
Now apply the exponents.
10 x 1 x 4
Now combine.
40
