Answer:

B. C. and D.

Step-by-step explanation:

You just have to make sure that every input has ONE output. Or every x-value has a single y-value.

You can have (1,2) (4,8) and (7,12) but you can't have (1,2) (1,4) (2,4)

If you need me to go over it again, let me know! Hopefully this helps, and have a great day!

Answer:

The first option     (5.7km)

Step-by-step explanation:

Since we have a right angle triangle and we know two of its sides we can easily find out the thirds side (the value of d) by using the Pathagoras Theorem. In our case 7 and d are our legs and the hypotenuse is equal to 9, so...

(Based on the Pathagoras Theorem)

c^{2} = a^{2}  + b^{2}

9^{2} = 7^{2} + d^{2}

d^{2} = 9^{2} - 7^{2} \\d^{2} = 81 - 49\\d^{2} = 32\\d = \sqrt{32}\\

d ≈ 5.7km

There for aproximate distance across the lake is equal to 5.7km
