the answer is 5x^2-5x-10

Answer:

5x2 - 5x - 10 (IM SORRY IF IM WRONG)

Step-by-step explanation:

Given:

In 1999, the number of mosquitos = 2500

They tripled every year.

To find:

The model for this situation and find the number of mosquitos in 2005.

Solution:

The general exponential modal is

[tex]y=ab^x[/tex]          ...(i)

Where, a is the initial value and 0<b<1 is decay factor and b>1 is growth factor.

In 1999, the number of mosquitos is 2500.

Initial value: [tex]a=2500[/tex]

They tripled every year. So, growth factor is 3>1 and it is exponential growth.

Growth factor: [tex]b=3[/tex]

Putting [tex]a=2500[/tex] and [tex]b=3[/tex] in (i), we get

[tex]y=2500(3)^x[/tex]           ...(ii)

Here, y is the population of mosquitos after x year of 1999.

Therefore, the required exponential growth modal is [tex]y=2500(3)^x[/tex].

We know that,

[tex]2005-1999=6[/tex]

Putting x=6 in (ii), we get

[tex]y=2500(3)^6[/tex]

[tex]y=2500(729)[/tex]

[tex]y=1822500[/tex]

Therefore, the estimated number of mosquitos in 2005 is 1822500.

Answer:

There are 102 children

Step-by-step explanation:

Let us solve the question

∵ There are 272 people in an audience

∴ The total number of people = 272

∵ The ratio of adults to children is 5: 3

→ Find the sum of the two parts of the ratio

∴ The sum of the parts of the ratio = 5 + 3 = 8

→ By using the ratio method

→  Adults:  Children:  People

→  5        :   3            :  8

→  A        :   C           :  272

→ By using the cross multiplication

∵ C × 8 = 3 × 272

∴ 8C = 816

→ Divide both sides by 8

∴ C = 102

∵ C represents the number of children

∴ There are 102 children

Answer:

x = 10

Step-by-step explanation:

3x + 14 + 4x + 6 = 90

7x + 20 = 90

90 - 20 = 70

70 / 7 = 10

x = 10

Answer:

Point C: (4, 0)

Step-by-step explanation:

Parallelograms are quadrilaterals with two pairs of parallel sides, this means they will have the same slope between two line segments.

point slope form between two points:  y - y1 = m (x - x1)

point A (2, 6) and D (4,4):

slope: point form, 6 - 4 = m(2 - 4)

2 = -2m

m (slope)  = [tex]\frac {2}{-2}[/tex] = [tex]\frac {Change in X position}{ Change in Y position}[/tex]

now that you know the change in position, apply this to vertice B to get the position of the final vertice.

B(2, 2)

C (2 +2, 2-2) = C(4, 0)

The final position of C vertice for parrallelogram A(2,6), B(2,2), D(4,4) will be C(4,0)

Step-by-step explanation:

the 3rd choice is the same as all of the others just in fraction form .you need to keep fraction form for the statement to still be true

Answer: 1st one

Step-by-step explanation: All you got to think about is think of the fraction if the x value is odd and the y value is odd, when you add them together you will get and odd number. :)

Answer:

D.

Step-by-step explanation:

The idea of Manifest Destiny arose in response to the prospect of U.S. annexation of Texas and to a dispute with Britain over the Oregon Country, which became part of the union.

Answer:

D. Annexation of Texas.

Step-by-step explanation:

Remember from the previous answer, the Manifest Destiny was the "justifiable source" in the expansion of the US westward. What is not known as Texas, was part of the Manifest Destiny. During this time, the Mexican Government allowed for US citizens to populate the lands that stretch from Texas to parts of California. However, it is important to note that they did not allow slavery, which is a large factor in the Texas Independence. With the independence of Texas, and the annexation of Texas from the Republic of Texas to the state of Texas, the US added a large sizable chunk to it's borders, further expanding the US in the southwest sector.

Answer:

6+3b=x

Step-by-step explanation:

The total amount of money spend on crackers and cheese is given by the inequality 3b + 6 ≤ 15

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

Let the amount spend on cheese be = $ 6

The number of boxes of crackers = b

The cost of one box of crackers = $ 3

So , the total amount for b box of crackers = 3b

The maximum amount of money that can be spend = $ 15

And , total amount of money spend on crackers and cheese is

3b + 6 ≤ 15

Subtracting 6 on both sides , we get

3b ≤ 9

Divide by 3 on both sides , we get

b ≤ 3 boxes

Therefore , the value of b is 3 boxes

Hence , the inequality is 3b + 6 ≤ 15

Mari spends $6 on cheese for a party she also plans to buy b boxes of crackers that cost $3 per box.Which inequality shows that Mari wants to spend at most $15 on cheese and crackers for the party?

Answer:

x = 9

Step-by-step explanation:

To answer this equation We have to find the value of x so that and A, B, and C add up to 180. Since angle A and C are both 6x that means the number of those angles are the same. Therefore the equation for this problem is:

180 = 6x + 6x + 8x

Now substituting 9 in for the x values;

180 = 6(9) + 6(9) + 8(9)

180 = 54 + 54 + 72

180 = 180

Answer: The total number of student in the school  = 240.

Step-by-step explanation:

Let x be the total number of students in the school.

Given: 35% of the students at Charles drew middle school are 6th graders.

i.e. Number of sixth graders = 35% of x = 0.35x   [35% = 0.35]

Since there are 84 sixth graders in the school,

So  [tex]0.35x=84[/tex]

Divide both sides by 0.35, we get

[tex]x=\dfrac{84}{0.35}=\dfrac{84\times100}{35}=240[/tex]

Hence, the total number of student in the school  = 240.

Answer:

Suppose that we have a converging series like:

(a₁ + a₂ + a₃ + ... ) = A

or

∑aₙ = A

So this series converges to the value A.

Now, let's multiply all the coefficients by a real number c, different than zero, then the sum is:

(c*a₁ + c*a₂ + c*a₃ + ...)

now we can take the common factor c out, to get:

c*(a₁ + a₂ + a₃ + ...)

And the thing inside the parentheses is equal to A, then we have:

c*(a₁ + a₂ + a₃ + ...) = c*A

So the series still converges for any value of c.

Now, suppose that this series diverges (to minus infinity or infinity)

Then we have:

(b₁ + b₂ + b₃ + ...) = ∞

Same as before, we multiply all the terms by the same number c:

(c*b₁ + c*b₂ + c*b₃ + ...)

again, we take the common factor out:

c*(b₁ + b₂ + b₃ + ...)

And same as before, we get:

c*(b₁ + b₂ + b₃ + ...) = c*∞

and c*∞ is still equal to ∞ (or -∞ if c is negative), so the series still diverges.

Answer:

Mean = 35

Median = 0.5(n + 1)th term

Median = 0.5(9) = 4.5th term

(30 + 34) /2 = 32

Mode = 30 ( most frequent)

Range = (51 - 20) = 31

Mean = 72

Median = 0.5(n + 1)th term
