drag the items to categorize them as functions or not functions.

my keyboard is broken. sometimes when i press the "h" key, a "u" shows up on the screen. other times, a "g" shows up. weird.

when i turn the knob left, the door locks every time.

The second condition is a function.

'When I turn the knob left, the door locks every time.'

Step-by-step explanation:

We know function is a special type of relation in which every element of a set ( Here set A(let) includes {H} in first condition and {turning the knob} in second condition) is related to other set (Here set B(let) includes {output U and G} in first condition and{locking of door}in second condition) in such a way that every element of set A have one and only one image in set B.

Here,

In condition 1 one element of set A(pressing key H) have two image(output U and G both)

[which do not satisfies the condition for being a function.]

In condition 2 one element of set A(turning knob left) have only one image(locking of door every time.)

[which satisfies the condition of being function]

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
