if there's 1 boy to every 4 girls, there's going to be 5 boys for every 20 girls
Answer:
1.838181818181818
Step-by-step explanation:
5.4d + 0.1d = 0.66 + 9.45
5.5d = 10.11
d = 10.11 / 5.5
d = 1.838181818181818
Answer:
4g = 64
Step-by-step explanation:
Let n = the number of nectarines
and g = the number of grapefruit
We have two conditions that must be satisfied to represent the situation:
(1) n = 3g
(2) n + g = 64
If you need one equation, we can substitute (1) into (2) and get
4g = 64
It's a quadratic so the parent function will be

We can see that it has been shifted to the right 5 units, which gives us a new function

It has also been shifted up 9 units:

But it has also been flipped across the y-axis which makes this the final change we need to do:
Step-by-step explanation:
∫₀³⁰ (r/V C₀ e^(-rt/V)) dt
If u = -rt/V, then du = -r/V dt.
∫ -C₀ e^u du
-C₀ ∫ e^u du
-C₀ e^u + C
-C₀ e^(-rt/V) + C
Evaluate between t=0 and t=30.
-C₀ e^(-30r/V) − -C₀ e^(-0r/V)
-C₀ e^(-30r/V) + C₀
C₀ (-e^(-30r/V) + 1)
I got the same answer. Try changing the lowercase v to an uppercase V.
