Answer:

The answer is C. 

In order to make an exponent positive, you just switch it to the opposite part of the fraction. So, for example, 

x^-3= 1/x^3

or 

1/x^-5 = x^5/1

You just switch it to the opposite part of the fraction, and make the exponent positive.

Samantha sends her son, Barry, to a preschool center on certain days. The cost of preschool is $45 per day along with a fixed mo
Travka [436]

Answer: Option D

D. 880 = 45d + 70; 18\ days

Step-by-step explanation:

We know that the cost of preschool is $ 45 per day plus a monthly fee of $ 70.

We also know that a total of $ 880 was paid last month

To write an equation that represents this situation, let us call "d" the number of days that Barry attends school

So the cost was:

45d + 70 = 880

Now we solve the equation for the variable d

45d= 880-70

d= \frac{810}{45}

d= 18\ days

Therefore answer is the option D

Marina CMI [18]
The solution to your problem is as follows:

Given: 
P₀ = 5,642×10^6 people, 
i = 1.3% = 0.013 per year, 
n = 2020 - 1994 = 26 years, 

We get: 
<span>
Pn = P₀ e^(i.n) </span>
. . .= 5,642×10^6×e^(0.013×26) 
<span>. . .= 7,911×10^6 people

Therefore, the </span>the world's predicted population in the year 2020 is <span>7,911×10^6 people.
