Answer:

b is not a function

Step-by-step explanation:

To be a function there must be a one to one correspondence.

Each x must only go to one y

b has an x that goes to two different y's

1 goes to 5 and 13.  That makes it a relation not a function

A cable on a crane measures 89 yards 2 feet. How much total cable would be on 14 identical cranes? Convert the answer to larger
babymother [125]

we know that  

1 yard=3 feet

Multiply (89 yards 2 feet) by 14

(89 yards 2 feet)*14=89*14 yards 2*14 feet-------> 1,246 yards 28 feet

convert 28 feet to yards

28 ft=(28/3) yards=9.33 yards

9.33 yards=9 yards+0.33 yards

0.33 yards=1 foot

so

9.33 yards=9 yards+1 foot

substitute

1,246 yards 28 feet=1,246 yards +9 yards+1 foot----->1,255  yards + 1 foot

therefore

<u>the answer is the option</u>

C. 1,255 yards 1 foot

What does it mean to square a negative number​
Andrej [43]

Answer:

This is because to square a number just means to multiply it by itself. For example, (-2) squared is (-2)(-2) = 4. Note that this is positive because when you multiply two negative numbers you get a positive result.
