Heres a photo I took of a diagram. I hope it helps!
I'm assuming you meant to write a^4 = 625.
If that is the case, then note how 625 = 25^2, and how a^4 is the same as (a^2)^2
So we go from this
a^4 = 625
to this
(a^2)^2 = 25^2
Apply the square root to both sides and you'll end up with: a^2 = 25
From here, apply the square root again to end up with the final answer: a = 5 or a = -5
As a check:
a^4 = (-5)^4 = (-5)*(-5)*(-5)*(-5) = 25*25 = 625
a^4 = (5)^4 = (5)*(5)*(5)*(5) = 25*25 = 625
Both values of 'a' work out
Alright so first you wanna use the inverse operation for the number that doesnt have the variable.
Math:
14-6=8
now that you have 4x=8 simply divided 8 by 4 and you would get 2 =x
To check the answer just simply switch x with 2 and done.
good luck!
Answer:
The answer to your question is:
a) P(3) = 5818 mosquitoes
b) 4 days
Step-by-step explanation:
Data
P(t) = Poekt
a)
Po = 1000 mosquitoes
Pt = 1800
t = 1 day
P(3) = ?
1800 = 1000 e1k
1800 / 1000 = e 1k
e 1k = 1.8
1k = In 1.8
k = 0.587
P(3) = 1000 e (0.587)(3)
P (3) = 1000 e 1.761
P(3) = 5818. 2 mosquitoes
b)
P(t) = 10,000
10000 = 1000 e 0.587t
10000 / 1000 = e 0.587t
10 = e 0.587t
In 10 = in e 0.587t
2.3 = 0.587t
t = 3.92 days ≈ 4 days
Answer:
60m - 36
Step-by-step explanation:
<em>This equation is asking you what is this quantity times 12? So you distribute the 12 (multiply everything in the quantity by 12)/</em>
(5m - 3)12
12 x 5m = 60m
12 x (-3) = -36
60m - 36
