Answer:
(-7, 3)
Step-by-step explanation:
You already said the point of C is (-5, 2)
Now all we simply do is change the values of each X and Y value respectively.
When moving to the left, the value is subtracted for X.
When moving up the value is added to Y.
-5-2 = -7
2+1 = 3
At hour one, there is 1 organism. At hour two, there is five more organism. At hour three. there will be 6 x 5 = 30 more organisms, etc
This is a geometric sequence with a = 1 (i.e. number of organisms at hour one), r = 5 (number of reprications per hour).
The total number of organisms at hour seven is the sum of the first seven terms of the sequence given by a(r^n - 1)/(r - 1) = 1(5^7 - 1)/(5 - 1) = (78125 - 1)/4 = 78124/4 = 19,531
C. 4:5=32:40 is your answer
Treat each ratio like fractions. Note the equal sign. This means that, when each fraction is simplified, they would be the same.
4/5 = 4/5
(32/40)/(8/8) = 4/5
4/5 = 4/5
∴ (C) is your answer

Answer:
19
Step-by-step explanation:
f(x) = 2x^2 + 1
Let x= 3
f(3) = 2 * (3)^2 +1
Exponents first
= 2 * 9+1
Then multiply
= 18+1
Add
= 19
