Answer:
Step-by-step explanation:
<span>Answer: A) exponential, because there is a relatively consistent multiplicative rate of change

temperature thrice. If you compare time=0 until time=30, you will get this table
t(10)- t(0)= 180-200= -20
t(20)-t(10)= 163-180= -17
t(30)-t(20)= 146-163= -17
</span>t(40)-t(30)= 131- 146= -15
t(50)-t(40)= 118-131= -13
t(50)-t(40)= 107-118= -11
There is something weird about the 2nd and 3rd value because it was same -17., but there seems to be a +2 change to the difference. So, the graph would be exponential with a <span>relatively consistent multiplicative rate of change</span>
Answer:
B) x < 9 or x > 23
------------------------------------
I'm so sorry if I'm not correct, but that's the only answer that makes any sense to the sentence.
Answer:
for a, look at my picture
b = 19.5 inches
Step-by-step explanation:
A is simple. thats my take on it, but other people coudl've drawn it differently
B is more difficult. I made triangle QRS like that so i can make a ratio.
My ratio:
QX:QY = QR:QS
8:12=13:QS
13*12 = 8*QS
156/8 = 19.5
therefore 19.5 inches
