Answer:
Step-by-step explanation:
Exponential growth function is
Where 'a' is the initial population
r is the rate of growth and x is the time period in years
a steady population of 32,000. So initial population is 32,000
an increase of 8% per year. the rate of increase is 8% that is 0.08
a= 32000 and r= 0.08
Plug in all the values in the general equation
Use u subsitution
the derivitive of eˣ+2 is eˣ
u=eˣ+2
du/dx=eˣ
du=eˣdx
we see a eˣdx in the problem
sub du for that and u for eˣ+2
remember
sub eˣ+2 for u
don't forget to add a constant since the derivitive of a constant is 0
the original function is
where C is a constant
Answer:
162.06
Step-by-step explanation:
sorry i'm not the best an explaining but i'm confident in my answer.
the first thing to do is get rid of the ² in x²+y²=24, we do this by √24 which ≅4.90 (i rounded to the hundreth place)
then we have this
x-y=6
x+y=4.90
I am using the elmination method. To do that you need to get two letters to have the same coefficient (in 4x 4 is the coefficient) with oposite signs (one possitive one negitive)
In our equation here we see that the same coefficient is 0, and there is oposite signs for y. Therefore we can add the two equations and get
2x=10.9 (the y cancels out)
now we have a simple equation and all that is left is to solve it
10.9/2=5.45
x=5.45
Now we need to find y we do that by pluging the x value into one of the equations I choose the first one becasue its easiest.
(5.45)-y=6
y= - .55
now that we have both x and y plug them into the final equation (5.45)³-(-.55)³= 161.89-(-.17) =162.06
Therefore x³-y³≅162.06!

Answer:
There are (14 - 8) daisies = 6 daisies
roses / daises = 8 / 6 = 4 / 3
flowers / daises = 14 / 6 = 7 / 3
There's nothing below to select it from. I looked.
