Answer:

$P=89,000e^{-.018t}$

Step-by-step explanation:

I used this equation formula and just input the numbers given:

$P=P_{o}e^{rt}$

Where

P= final population

$P_{o}$ = original population

r = rate of growth

t = time

Hope this helps!

Could anyone help me with these?

Part A:

Derrick is incorrect.
A yard is equivalent to 3 feet.
Thus, 20 yards will be equivalent to 60 feet.

The width is 20 yard and 2 feet. It's the same as 60 feet and 2 feet, or 62 feet. Thus, Derrick is incorrect.

Part B:

Let's calculate the area of the parking lot.

We know the width is 62 feet from part A.
The length is 30 yards, or 90 feet.

Multiply the length and width to get the area in square feet.

$90 \times 62=5580$

The parking lot has an area of 5580 square foot.
It costs 2 dollars per square foot to repave the parking lot. Multiply the area by 2 dollars.

$5580 \times 2=11160$

It will cost $11,160 to repave the whole parking lot.

Y=143.3(5)^2+1823.3(5)+6820

MA_775_DIABLO [31]

As the question is written, the <em>correct answer</em> is:

19519.

Explanation:

Our question states

y = 143.3(5)² + 1823.3(5) + 6820

To evaluate this, we use the order of operations (PEMDAS). There is nothing to be evaluated in parentheses, so P is taken care of.

The E part, exponents, is 5². This is 25, which gives us:

y = 143.3(25) + 1823.3(5) + 6820

Next we have M and D, multiplication and division (in the order they appear). Our multiplication is:

143.3(25) = 3582.5; and

1823.3(5) = 9116.5.

This gives us:

y = 3582.5 + 9116.5 + 6820

Lastly, we add these:

y = 12699 + 6820

y = 19519

Question b with explanation?

Step2247 [10]

Hello!

The answer is 40. All we have to do is find the number of 16 year olds who spent between 25-35 minutes in social media. That is 145. The number of 13 year olds who spent the same amount of time is only 105, therefore 40 more 16 year olds spent between 25 and 35 minutes on social media.
