Answer:

A) is a function

B) f(x) is greater

C) x = 12

Step-by-step explanation:

A) Yes, the relation is a function.

A function has a unique input value for each output value. There are no repeated x-values, so this relation is a function.

B) The table says y=6 for x=6.

f(6) = 2(6)+16 = 28

f(x) has a greater value for x=6.

C) Substituting the given information, we have ...

40 = 2x +16

24 = 2x

12 = x

The value of x is 12 when f(x) is 40.

If a swimmer swims 85.4 yards in 5 minutes, how many meters will he/ she swim in 70 seconds

DaniilM [7]

Distance swam in 5 minutes = 85.4 yards

Since, 1 min = 60 seconds and 1 yard = 0.91 meter

5 minutes = $5 \times 60 = 300$ seconds

85.4 yards = $85.4 \times 0.91 = 77.7$ meters

So, Distance swam in 300 seconds = 77.7 meters

Now, we will use unitary method to determine the distance swam in 70 seconds.

Distance swam in 1 second = $77.7 \div 300$ = 0.26 meter

So, Distance swam in 70 seconds = $70 \times 0.26$

= 18.2 meters

Therefore, the swimmer took 70 seconds to cover the distance of 18.2 meters.
