Answer:
Z'(-2, 3)
Step-by-step explanation:
For 90° CW rotation, the transformation is ...
(x, y) ⇒ (y, -x)
Z(-3, -2) ⇒ Z'(-2, 3)
Answer:
1.932 days (or approximatelly 1 day, 22 hours and 22 minutes)
Step-by-step explanation:
The inicial concentration is 60,000, and this concentration triples every 4 days, so we can write the equation:
P = Po * r^t
where P is the final concentration after t periods of 4 days, Po is the inicial concentration and r is the ratio that the concentration increases (r = 3)
Then, we have that:
102000 = 60000 * 3^t
3^t = 102/60 = 1.7
log(3^t) = log(1.7)
t*log(3) = log(1.7)
t = log(1.7)/log(3) = 0.483
so the number of days that will take is 4*0.483 = 1.932 days (or approximatelly 1 day, 22 hours and 22 minutes)
Answer: it is invalid
Step-by-step explanation: it is invalid because the data table has 30 out of 100 people stating that they prefer to view movies in theater. This does not have the same ratio as 300 out of 400, and would only work had he said 300 out of 1000. Thus, he is incorrect in his inference.
Seems all good to me at least!
Answer:
In my best opinion I think the answer is E because...........
Step-by-step explanation:
A) 4 x 3 = 12
B) 4 x 4 x 4 = 64
C) 3 x 3 x 3 x 3 = 81
D) 2 x 2 x 2 x 2 x 2 x 2 = 64
and.....
E) NONE OF THE ABOVE! because you asked witch one equals 43 i solved them 4 times but i figured it out. None of the above!!
I hope i got the answer right, have a great day!!
