Answer:

It can be modeled with the equation A=P(1.02)^6 but needs a starting population number to finish.

Step-by-step explanation:

To find the population in a future year, use the formula:

A = P (1+/-r)^t

where A is the amount, p is the starting population, r is 2% or 0.02, and t is the number of years.

Since the population is increasing it is addition. Substitute r=0.02 and t=6. Without a starting population, we cannot find the population in 6 years.

A = P (1+r)^t\\A=P(1+0.02)^6\\A=P(1.02)^6

Alexei wants to hang a mirror in his boat and put a frame around it. The mirror and frame must have an area of 19.25 square feet
zhuklara [117]

Let

x---------> the thickness of the frame in feet

At-------> Area of the mirror and the frame in square feet

we know that

At=19.25ft^{2} ------> equation 1

At=(3+2x)*(5+2x)\\ At=3*5+3*2x+5*2x+2x*2x\\ At=15+6x+10x+4x^{2} \\ At=4x^{2} +16x+15--------> equation 2

equate equation 1 and equation 2

19.25=4x^{2} +16x+15\\ 4x^{2} +16x+15-19.25=0\\ 4x^{2} +16x-4.25=0

therefore

the answer is the option

C. 4x2 + 16x - 4.25 = 0

Whats 126/399 in its simplest form
marusya05 [52]
A common factor of both 126 and 399 is 3 so we can divide both numbers by 3.

126 / 3 = 42
399 / 3 = 133

A common factor for both 42 and 133 is 7 so we can divide both numbers by 7.

42 / 7 = 6
133 / 7 = 19

19 is a prime number so we can't reduce it anymore, therefore 126/399 in its simplest form is 6/19

It costs $3.99 for 32 fl. oz. of soda. What is the unit rate?<br> Your answer
Marrrta [24]
The unit rate means we need to find it per one soda can. So, 32/32 is one. We do the same to $3.99. $3.99/32 is about 13 cents.

Unit rate is: 13 cents per soda can

The moon is about 240,000 miles from Earth. What is the distance written as a whole number multiplied by a power of ten?
ololo11 [35]

We need to find 240,000 written as a whole number multiplied by a power of ten.

We need to get rid of the four zeros behind 24 in 240,000.

24 would be our whole number.

We would need to multiply 24 by 10,000 to get 240,000.

10,000 is equal to 10^{4} because there are 4 zeros. Ex. when multiplying 200 by 30, we first multiply 2 * 3 then we add 3 zeros to the end of  6. So for 10*10*10*10, we add 4 zeros to the end of 1 which equals 10,000.

So the answer would be 24 × 10^{4}
