Answer:

The population of deer at any given time = 200(e^0.03t)  ÷ (1.5 + (e^0.03t))

Step-by-step explanation:

This is an example of logistic equation on population growth

carrying capacity, k = 200

Rate, r = 3% = 0.03

Initial Population, P1 =  80

P(t) =?

P(t) = (P1 (k)(e^rt)) ÷ (k- P1 + P1(e^rt))

P(t) = (80 (200)(e^0.03t)) ÷ (200 - 80 + 80(e^0.03t))

     = (16000(e^0.03t))  ÷ (120 + 80(e^0.03t))

      = 200(e^0.03t)  ÷ (1.5 + (e^0.03t))

Answer:

225 words

Step-by-step explanation:

In order to find the answer to this question we have to find how many words she writes in 1 minute. To do this you need to divide 90 words by 4 minutes:

(90)/4 = 22.5 words/minute

Now that the words per minute is found, we can multiply it by the 10 minutes to find how many words she can write in 10 minutes:

(22.5)(10) = 225

Therefore, Sara can type about 225 words in 10 minutes.

I hope this helps!!

Step-by-step explanation:

Larry  Fitzgerald caught 109, John Brown caught  65 and  Michael Floyd caught 52.

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

An equation is a set of variables that are constrained through a situation or case.

Let's say the number of passes that Larry caught = L

Let's say the number of passes that John caught = J

Let's say the number of passes that Michael caught = M

Given,

Cardinals caught a total of 226 passes.

So,

L + J + M = 226

Larry Fitzgerald caught 44 more passes than John Brown

L = 44 + J

Michael Floyd caught 13 fewer catches than John Brown.

M = J - 13 ⇒ J = M + 13

Substituting this J into the above equation,

M = 52 , L = 109 and  J = 65

Hence, Larry  Fitzgerald caught 109, John Brown caught  65 and  Michael Floyd caught 52.

Answer:

1 by 4

Step-by-step explanation:

The computation of the probability is as follows

Here we assume the moves in a complex numbers i.e. a, b and c

Now the frog begins with the starting point.

So it would become easy to represent the exactly one element in a set that has lower or equal than 1

|a + b + c| , |a + b - c|, |a - b + c|, |a - b- c|

So here the probability is 1 by 4

The given expression is a difference of squares, so we have

16 (a + b)² - 49 (a - b)² = 4² (a + b)² - 7² (a - b)²

… = (4 (a + b))² - (7 (a - b))²

… = (4 (a + b) - 7 (a - b)) (4 (a + b) + 7 (a - b))

… = (4a + 4b - 7a + 7b) (4a + 4b + 7a - 7b)

… = (-3a + 11b) (11a - 3b)

Answer: 144 boxes.

Step-by-step explanation: 15 is 1/4 of an hour. That means you need an hour to make 48 boxes. Then, multiply that by 3.

Answer:

144

Step-by-step explanation:

3 hours is 180 minutes

180/15 = 12

12*12= 144

so she will sell 144 boxes of cookies

Answer:

No, negative

Step-by-step explanation:

the sign of the product of two numbers with opposite signs is a negative.

-5 * 4 = -20

5 * -4 = -20

The statement "the sign of the product of two numbers with opposite signs is a positive" is false.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

It is given that:

The statement is:

The sign of the product of two numbers with opposite signs is a positive

Let x be the number and x > 0

And let y be the number y < 0

The product of the above two numbers:

xy = -(A)  because x > 0 and y < 0

Here A is the positive real number or A > 0

The sign of the product of two numbers with opposite signs is negative.

Thus, the statement "the sign of the product of two numbers with opposite signs is a positive" is false.

Answer:

∆ adc is congruent to ∆ abc by asa congruence rule where CA is common side,

so CD and CB are congruent therefore angle cbe is same as angle cde

so ∆ bce and ∆ dce are congruent by ASA congruence rule

The triangle BCE is congruent to triangle DCE if ∠1 is congruent to ∠2 and ∠3 is congruent to ∠4.

Two triangles are said to be congruent if the length of the sides is equal, a measure of the angles are equal and they can be superimposed.

For the figures to be congruent they must be the same size and shape or one could mirror the other since they mirror each other and are the same size and shape they are congruent.

In triangle ∆ ADC and ∆ ABC

∠2 = ∠1

∠4 = ∠3

Thus, ∆ ADC ≅ ∆ ABC

∆ ADC is congruent to ∆ ABC by ASA congruence rule where CA is common side.

Also, CD and CB are congruent therefore angle CBE is same as angle CDE.

Similarly, ∆ BCE and ∆ DCE are congruent by ASA congruence rule.

The triangle BCE is congruent to triangle DCE if ∠1 is congruent to ∠2 and ∠3 is congruent to ∠4.

Answer:

Either increase the number of acres that can be used for strawberry fields (by buying more land)..If we use the same numbers from earlier, then the farmer should use approximately 16.65 acres of land (or just 17 acres of land)

So if the farmer has 17 acres of land or more, then he will make more than $70,000 per year

Step-by-step explanation:

Use the proportions from earlier

We have the point (5, 21000)

70,000/21,000 = 3.3

To find the x-value multiply 3.3 by 5

3.3 * 5 = 16.65

We can even use the other point's values to find the exact same answer

Point (3.5, 14700)

70,000/14,700= 4.7619047619

4.7619047619 * 3.5 = 16.66 (literally about the same)

Answer:

(6,9) and (7,9) - assuming the graph only has a single quadrant and the rectangle is vertical

Step-by-step explanation:

We know that the distance between (6,1) and (7,1) is one unit. Because a rectangle has 2 pairs of equal sides, we know that the distance between the 2 missing coordinates is equal to one. We then add these two units. Because the rectangle has a parameter of 18 units, we then have to subtract these 2 units from the total, leaving us with 16 units for both sides. We then divide 16 by 2 because there are 2 sides, leaving us with 8 units for each side. Assuming we are working with a coordinate graph (with only one quadrant instead of 4 on a coordinate plane), and assuming the rectangle is vertical, the missing coordinates should be 8 units above the coordinates you were given.

Question:

The grocery store has 20% off from the original price on cereal. The equation for finding the sale price would be y = x - (.20x). What is the sale price if the cereal cost $4.00?

Answer:

The sales price is $3.20

Step-by-step explanation:

Given

[tex]y = Sales\ Price[/tex]

[tex]x = Cost[/tex]

[tex]y = x - (0.20x)[/tex]

Required

Determine y when x = 4.00

To do this, we simply substitute 4.00 for x in [tex]y = x - (0.20x)[/tex]

[tex]y = 4.00 - (0.20 * 4.00)[/tex]

[tex]y = 4.00 - 0.80[/tex]

[tex]y = 3.20[/tex]

Hence, the sales price is $3.20
