Answer:

The maximum number of mosquitoes is 7

Step-by-step explanation:

Given

[tex]m(x)= x^2 + 14x[/tex]

Required

Determine the maximum number of the function

First, we differentiate the given function w.r.t x

[tex]m'(x) = -2x + 14[/tex]

Then, we equate m'(x) to 0

[tex]0 = -2x + 14[/tex]

Lastly, we solve for x

[tex]0 = -2x + 14[/tex]

Make 2x the subject

[tex]2x = 14[/tex]

Make x the subject

[tex]x = 14/2[/tex]

[tex]x = 7[/tex]

Answer:

49 Million

Step-by-step explanation:

Answer: [tex]x+x^2+x^3+x^4[/tex]

Step-by-step explanation:

As per given,

Number of wives = [tex]x[/tex]

Number of sacks = [tex]x (\text{Number of wives} )= x\times x = x^2[/tex]

Number of cats = [tex]x(\text{Number of sack})[/tex][tex]= x \times x^2=x^3[/tex]

Number of kits = [tex]x(\text{Number of cats} )=x\times x^3=x^4[/tex]

Now , the total number of kits, cats, sacks, and wives going to St. Ives = [tex]x+x^2+x^3+x^4[/tex]

Hence, the required ex[pression:  [tex]x+x^2+x^3+x^4[/tex]

Step-by-step explanation:

"y3"   was replaced by   "y^3".  1 more similar replacement(s).

Simplify: y5 by y3

1.1    y5 divided by y3 = y(5 - 3) = y2

Final answer:

y2

y³y⁻⁵ can be written in the form of positive exponent is 1/y².

An expression is combination of variables, numbers and operators.

The given expression is y³y⁻⁵

y power three times of y power minus five.

We need to simplify the expression using only positive exponents

From properties of exponents we have, when bases are same then the powers will be added

y³⁻⁵

y⁻²

This can be written as 1/y² as positive exponent.

Hence,  y³y⁻⁵ can be written in the form of positive exponent is 1/y².

Answer:

5.8 miles

Step-by-step explanation:

Distance of library(3, 2) to the supermarket (6, 7) using distance formula, [tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

Where,

[tex] (3, 2) = (x_1, y_1) [/tex]

[tex] (6, 7) = (x_2, y_2) [/tex]

Plug in the values into the formula

[tex] d = \sqrt{(6 - 3)^2 + (7 - 2)^2} [/tex]

[tex] d = \sqrt{(3)^2 + (5)^2} [/tex]

[tex] d = \sqrt{9 + 25} [/tex]

Answer:

Step-by-step explanation:

How to solve your question

Your question is

2000x+6000=3600−40000

Subtract the numbers

2000x+6000=3600−40000

2000x+6000=−36400

Subtract 

6000

60006000

 from both sides of the equation

2000+6000=−36400

2000x+6000=-364002000x+6000=−36400

2000+6000−6000=−36400−6000

Divide both sides of the equation by the same term

2000=−42400

2000x=-424002000x=−42400

20002000=−424002000

Answer:

17 inches

Step-by-step explanation:

An obtuse triangle is the triangle in which one of the side is the longest. It contains an obtuse angle and the longest side is the side that is opposite to the vertex of the obtuse angle.

Let the three sides of the obtuse triangle be a, b and c respectively with c as the longest side. Let a = 9 inches and b = 14 inches.

Now we know that for an obtuse triangle,

[tex]$c^2 > a^2 +b^2$[/tex]

[tex]$c^2 > (9)^2 +(14)^2$[/tex]

[tex]$c^2 > 81 +196$[/tex]

[tex]$c^2 > 277$[/tex]

c > 16.64

Therefore the smallest possible whole number is 17 inches.

It should be noted that the length of the unknown side will be 17 inches.

From the information given, we are informed that the sides of an obtuse triangle measure 9 inches and 14 inches.

Therefore, the third side will be:

c² = 9² + 14²

c² = 81 + 196

c² = 277

c = ✓277

c = 16.64

c = 17

In conclusion, the correct option is 17 inches.

Step-by-step explanation:

Given that:

Price paid to buy 5 bags of chips = $6

To find:

Price per bag of chips in two digits after the decimal.

Solution:

To find the price of each bag of chips, we need to divide the price of 5 bags of chips with 5.

i.e. we need to divide $6 with 5, then we will get the price of each bag of chips.

[tex]\text{Price of each bag of chips}=\dfrac{\text{Price of 5 bags of chips}}{5}\\\Rightarrow \dfrac{\$6}{5} = \bold{\$1.2}[/tex]

Therefore, the answer is:

Price of each bag of chips is $1.2.

Step-by-step explanation:

1 in is 35 feet

1.25 * 35= 43.75 feet

Answer:

43.75

Step-by-step explanation:

1.25 * 35 = 43.75

Answer:

y = 17.5

It says y is proportional to x, and y = 35 when x = 140, but we don't know what y is when x = 70. So since y is proportional to x and x = 140 we have to find out how 140 gets to 70, and that is dividing by 2 because 70 is half of 140. So then you would just divide the previous y value, 35, by 2, and you would get 17.5. And there you go, you've got you're answer.
