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
The answer is: [D]: " 2.6 " .
_____________________________________________________
Given: a = - 2.6 ; What is the value of "-a "?
_____________________________________________________
So, what is the value of " - (-2.6)" ?
_____________________________________________________
The opposite of a negative is a positive;
so, " - (-2.6) = 2.6 " ; which is: "Answer choice: [D] " .

Nikita's distance from her for the second part of the race was 1.5 kilometers.
Since Nikita ran a 5-kilometer race in 39 minutes (0.65 of an hour) without training beforehand, and in the first part of the race, her average speed was 8.75 kilometers per hour, while for the second part of the race, she started to get tired, so her average speed dropped to 6 kilometers per hour, to determine which expression represents Nikita's distance for the second part of the race the following calculation must be performed:
- 8.75 x 0.65 + 6 x 0 = 5.68
- 8.75 x 0.50 + 6 x 0.15 = 5.275
- 8.75 x 0.40 + 6 x 0.25 = 5
-
100 = 60
- 40 = X
- 40 x 60/100 = X
- 24 = X
- 39 - 24 = 15
- 15 = 1/4 hour
- 6/4 = 1.5
Therefore, Nikita's distance from her for the second part of the race was 1.5 kilometers.

Answer: 12.4 cm
Step-by-step explanation:
Since we are given the volums, we can work our way backwards to solve for radius, and then for diameter.
Now that we have r, we multiply it by 2 to get diameter.
