Answer:

$P(t) = 29816591(1.025)^{t-5}$

Step-by-step explanation:

Equation:

The equation for the population of California, in t years after 1990, is given by:

$P(t) = 29816591(1.025)^t$

In which 29816591 is the initial population, that is, the population in 1990.

From 1995:

First, we have to find the population in 1995(5 years after 1990), which is P(5), which we will consider as the initial value in the equation.

$P(5) = 29816591(1.025)^5 = 33734736$

Since t is still given in years after 1990, we have to subtract t by 1995 - 1990 = 5 in the exponent. So

$P(t) = 29816591(1.025)^{t-5}$

Evaluate. 2 -2 4 undefined

Answer:

Step-by-step explanation:

We have to get the value of the expression of - ∛(- 8).

Now, we can write the expression as

- ∛(- 8)

= $-\sqrt[3]{-8}$

= $-(-8)^{\frac{1}{3} }$ {Converting into exponent form}

= $-[(-2)^{3} ]^{\frac{1 }{3} }$ {Since (- 2) × (- 2) × (- 2) = - 8}

= $- [(-2)^{3\times \frac{1}{3} } ]$ {Since we know that $[x^{a}] ^{b} = x^{ab}$ }

= - [- 2]

I need help with these 2 questions

k0ka [10]

#1 w=9 because:
2w+2(2w+3)=60
2*2w=4w and 2*3=6
2w+4w+6=60
Then: 2w+4w= 6w
6w+6=60
I just tried each answer I knew it had to be 8 or 9
So I tried 8 and it didnt work then I tried 9 and it did
6*9= 54+6=60
w=9
#2 I have a picture for this one I worked it out on paper. Check out the photo for the answer :)
Hope this helps!
