The equation relating female population with time requested by t = -ln(P) - 1/9ln(P + 1000)- 1/9ln(9/10)

An equation is an expression that shows the relationship between two or more numbers and variables.

Given that the female population is related to time t by;

[tex]t = \int\limits {\frac{(P+S)}{P((r-1)P-S)} } \, dP[/tex]

Now, to do partial fraction;

(P+S)/P((r-1)P-S) = A/P + B/((r-1)P-S)

P + S = A((r-1)P -S) + PB

if P = 0, then:

A = -1

If (r-1)P - S = 0

p = S/(r-1)

B = 1 + r - 1

B = r

Therefore,

[tex]t = \int\limits {\frac{(P+S)}{P((r-1)P-S)} } \, dP[/tex]

t = -ln|P| + ln|(r-1)P-S| + 1/r-1 x integral((r-1)/[(r-1)P-S])

t = -ln|P| + ln|(r-1)P-S| + ln|(r-1)P-S|/(r-1)

t = -ln|P| + (r/r-1)ln|(r-1)P-S|

Now substituting known constants then;

t = -ln|P|-1/9(ln|-0.9P - 900|)

t = -ln|P| - 1/9(ln|-0.9P -900|)

t = -ln|P| - 1/9(ln(|(-9/10)(P + 1000)|))

t = -ln(P) - 1/9ln(P + 1000)- 1/9ln(9/10)

as P >= 0, ln(P) and ln(P + 1000) doesn’t need abs value

Therefore, the equation relating female population with time requested by t = -ln(P) - 1/9ln(P + 1000)- 1/9ln(9/10)

Lila's error was that she added -7.13 to 63.97 to get -71.1

Lila steps are as folows

(−7.13 + 63.97) + (−54.8 − 3.4) = −71.1 + (−58.2) = −129.3

In the first bracket, Lila was suppose to subtract 7.31 from 63.97 since there is a negative in front of 7.31.

So, the correct expression should be

(−7.13 + 63.97) + (−54.8 − 3.4) = 56.84 + (−58.2) = 56.84 - 58.2 = −1.36

So, Lila's error was that she added -7.13 to 63.97 to get -71.1

The solution to simplifying the algebraic expression is: -4u² - 15u - 2

Algebraic expressions are defined as the idea of expressing numbers using letters or alphabets without specifying their actual values

The algebraic expression we want to simplify is:

3u² - 5u + 4 - (7u² + 10u + 6 )

Simplifying the bracket gives us:

3u² - 5u + 4 - 7u² - 10u - 6

Arranging like terms gives us:

3u² - 7u² - 5u  - 10u + 4 - 6

Answer:

  1. a linear model

  3. y = 24.97x +417.59

  4. 75 workers

Step-by-step explanation:

1. A graph of the data seems to show it nearly follows a straight line. We have used a linear function to model the data.

3. The linear regression model is ...

  y = 24.97x +417.59

4. The graphing calculator shows the point (x, y) ≈ (75.4, 2300) is on the line of best fit. Marco should recommend 75 workers for production of 2300 units per hour.

If you want to solve the linear equation ...

  2300 = 24.97x +417.59

you get ...

  x = (2300 -417.59)/24.97 ≈ 75.4

About 75 workers are needed.

Answer:

  72 M&Ms

Step-by-step explanation:

We understand the problem to say ...

That 7/12 full condition corresponds to 42 M&Ms being present.

  42 = 7/12·full

  full = 42(12/7) = 72

There were 72 M&Ms in the jar on Monday evening.

_____

Check

1/8 of 72 = 9 were eaten Tuesday

1/3 of the remaining 63 disappeared on Wednesday. That number is 21, so 63-21 = 42 remained after Wednesday. That is the number seen early Thursday.

There were 72 M & M's in the jar on Monday evening

Let the initial number be x.

When 1/8 of the M & M were eaten on Tuesday, the remaining proportion is:

Remaining = (1 - 1/8) * x

This gives

Remaining = 7x/8

When 1/3 of the M & M disappeared on Wednesday, the remaining proportion is:

Remaining = (1 - 1/3) * 7x/8

This gives

Remaining = 7x/12

On Thursday, the remaining number of M & M is 42.

This means that:

7x/12 = 42

Divide both sides by 7

x/12 = 6

Multiply both sides by 6

x = 72

Hence, there were 72 M & M's in the jar on Monday evening

Answer:

10.3lbs or 10 3/10 as a mixed number

Step-by-step explanation:

i have the same question on my test so i know this is right but here's an explanation: so 5 1/2 pounds is the same as 5.5 pounds, and if you add 10 pounds to 5.5 pounds, you get 15.5 pounds, which is 3 ounces away from 15.8 pounds. so adding 3 ounces to the 10 pounds, then adding that to the 5.5 pounds, you would get 15.8. therefore, your answer is 10.3lbs.

The puppy gained 10.3 pounds of weight in 1 year.

Subtraction is one of the arithmetical operations, to subtract means to take away from a group or a number of things.

Given that, Max was a puppy, he weighed [tex]5\frac{1}{2}[/tex] pounds. At his 1-year check-up with the vet, Max weighed 15.8 pounds.

[tex]5\frac{1}{2}[/tex] pounds = 5.5 pounds

Weight before 1 year = 5.5 pounds

Weight after 1 year = 15.8 pounds

Weight gained by the puppy in 1 year = 15.8-5.5 = 10.3 pounds

Hence, the puppy gained 10.3 pounds.
