For a relation to be a function it must be one-to-one or many-to-one.

One-to-many relation is not a function.

In the above options, C is One-to-many relation therefore cannot be a function.

The reason is that 3 alone maps onto -2 and 5, in the ordered pairs (3,-2) and (3,5). This disqualifies it from being a function.

Hence the graph of this relation will not pass the vertical line test

The correct answer is C

An apple tree originally costs $80 at the local nursery, but is on sale for 15% off. If a customer buying the tree has a coupon
attashe74 [19]
58 because 80 times 15 percent is 12. so you subtract 12 from 80 that gives you 68 then you subtract the coupon which is 10 dollars. you total is 58.

Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels at a rate of 65
koban [17]

Answer:

time = 1 hour 24 minutes

Step-by-step explanation:

Given that:

Eastbound train travels at a rate of 65 miles per hour

Westbound train travels at a rate of 85 miles per hour

So speed = 65 + 85 = 150 miles per hour

Total distance = 210 miles

We have to find the time

We know that

Distance = time * speed

OR

time = distance / speed

time = 210/150

time = 1.4 hours

Or it can be written as:

time = 1 hour 24 minutes

i hope it will help you!

PLEASE ANSWER!!! I WILL MARK YOU AS BRAINLIEST!!!! An object is launched straight up into the air with an initial velocity of 40
Lana71 [14]

Answer:

6.7 seconds

Step-by-step explanation:

Let's calculate the maximum height covered by the object

Max height= U²Sin²tita/2g

Where g is acceleration due to gravity

Max height= 40²(sin90)²/(2*9.81)

Max height= 1600/19.62

Max height=81.55 m

Total max height= 30+81.55

Total max height= 111.55 m

Time t it will take to travel from the max height at acceleration of 4.9 m/s²

S= ut + ½at²

u= 0 at Mac height

S= 111.5 m

111.5 = ½(4.9)t²

223/4.9= t²

45.5= t²

6.745 seconds= t

6.7 seconds= t
