The area is 31.5 units squared
Answer:
A, 12.5
Putting them in order was this:
10, 11, 11, 11, 12, 13, 13, 15, 15, 17
and the median is between 12 and 13, which is 12.5
(Hope that helps you. ^^)
Answer: 2w = 16
Step-by-step explanation:
From the question, we are informed that Luis walked for 16 minutes while Natalie walked for w minutes and that Luis walked twice as long as Natalie.
The number of minutes that Natalie walk will be:
2 × w = 16
2w = 16
Solving further will be:
2w = 16
w = 16/2
w = 8
Natalie walked for 8 minutes
Answer:
see explanation
Step-by-step explanation:
The vertex form of f(x) is
f(x) = (x - h)² + k
where (h, k) are the coordinates of the vertex
To obtain this form use the method of completing the square
add/subtract ( half the coefficient of the x- term )² to x² + 14x
f(x) = x² + 2(7)x + 49 - 49 + 36
= (x + 7)² - 13
The minimum value of f(x) is the y- coordinate of the vertex
vertex = (- 7, - 13), that is minimum value = - 13
This is pretty simple. 72 x 13 = 936
Therefor Val ran 936 meters.
