Answer:

100 bicycle

Step-by-step explanation:

Given the cost c in dollars of manufacturing x bicycles at a production plant expressed as C(x)=5x^2-1000x+63,500.

x is the number of bikes

To minimize the cost, dC/dx = 0

dC/dx = 10x - 1000

Since dC/dx = 0

0 = 10x - 1000

-10x = -1000

x = 1000/10

x = 100

Hence the number of bicycles that must be manufactured to minimize the cost is 100 bicycle

12x=120

X=120/12=10in

Answer:

This is undercoverage bias because only those attending the concert will have an opportunity to register an opinion.

Step-by-step explanation:

Undercoverage bias occurs when the sample chosen for a research is not representative of the entire population. Most times when research involving surveys to obtain the opinions of people on a subject matter, the entire population affected by the issue cannot be surveyed. A sample that represents the true population can be used for this research.

In the survey above, the sample that was surveyed was not representative of the entire population of citizens paying taxes on entertainment tickets. The selection process does not represent the true population.

Answer:

D.

Step-by-step explanation:

Answer:

Well you have to solve each problem first to make them the same. Let's do decimals.

a) The square root of 58 is 7.61577310586. Let's round that to 7.62. You can solve this with a calculator.

b) Simply -32.0, since it is a whole negative number.

c) I think there's a typo, 'C' is the second 'b)', which is 49/7. 49 divided by 7 is seven, hence the decimal would be 7.0

d) 2.65 repeated, already a decimal, does not need changed.

e) The square root of 6 is 2.44948974278. Let's round that to 2.45.

f) is just 0. no decimal, just 0.

Now that you have these as the same form of number, you have to put them into one of these categories. The categories can be found below.

Any square root number is irrational. Any never ending number is irrational, like pi, but there are none of those in this situation. So a, and e are all irrational.

Any repeated number, in this case, 2.65 repeated, is a rational number, as is any decimal or fraction, but there are none of these, so d is rational.

-32 is and integer, because it is a negative whole number, so b is an integer.

Whole numbers are any numbers 0+. So f is the only answer that is a whole number.

Natural numbers are any numbers 1+. So c or the second b is a natural number.

Hope this helps :)

Answer:

14kilometers

Step-by-step explanation:

diameter=2*radius.

Answer:

1,124.12 mm

Step-by-step explanation:

Steps to answering this question :

First determine the radius of the circle from the area of the circle

Use the radius determined above to calculate the circumference

Area of a circle = nr²

where r = radius

n = pi = 3.14

100,608.7mm = nr²

to determine the radius, divide both sides of the equation by 3.14

32,040.98726mm = r²

Find the square root  of 32,040.98726mm

√32,040.98726mm

r = 179mm

Circumference of a circle = 2nr

2 x 179 x 3.14 = 1,124.12 mm

Answer:

(23/2, 1/2)

Step-by-step explanation:

Let's solve this system through elimination by addition/subtraction:

Divide all three terms of the first equation by 3.  This results in the equivalent system

-2x - 2y = 33

2x + 4y = -32

Combining like terms results in:

2y = 1, and so y = 1/2.

Let's use the first equation and y = 1/2 to find x:

-6x - 6(1/2) = 66

This becomes -6x - 3 = 66, or -6x = 69, or x = -69/6 , or x = 23/2

The solution is thus (23/2, 1/2)

Step-by-step explanation:

Answer:

c = 1.05p

Step-by-step explanation:

the price of the hat before the increase was 100%, after the increase it becomes 100 + 5% = 105%. Representing it as a decimal becomes 1.05p

Let illustrate with an example.

The price of a hat was $100, after the 5% increase. the cost of the hat becomes

100 + (0.05 x 100) = 105

To find the percentage increase

divide 105 by 100 and subtract 1

(105/100) - 1 = 1.05

Answer:

here are my hypothesis

Step-by-step explanation:

0=0$

1= 5.99$

2 = 11.98$

3 = 17.97$

4 = 23.96$

5 = 29.95$

6 = 35.94$

Answer:

Step-by-step explanation:

f(x)= 36( 1 - 0.12)^x. F(x)= 36(0.88)^3. f(x)= 95.04    190-95.05 = 94.95 degree.

Because the temperature is going down, we will use (1-0.12) instead of (1+0.12). X=3 because it is what temperature after 3 min. x= time.

Answer:

[tex]n = 144m^2 - 1[/tex]

Step-by-step explanation:

__________________________________________________________

FACTS TO KNOW BEFORE SOLVING :-

__________________________________________________________

According to the question ,

[tex]3m = \frac{(n + 1)^{\frac{1}{2} }}{4}[/tex]

Lets multiply both the sides by 4.

[tex]=> \frac{(n + 1)^{\frac{1}{2} }}{4} \times 4 = 3m \times 4[/tex]

[tex]=> (n + 1)^{\frac{1}{2} } = 12m[/tex]

It can be also written as :-

[tex]=> \sqrt{(n + 1)} = 12m[/tex]

Lets square both the sides.

[tex]=> [\sqrt{(n + 1)} ]^{2} = (12m)^{2}[/tex]

[tex]=> n + 1 =144m^2[/tex]

[tex]=> n = 144m^2 - 1[/tex]

Answer:

He has 1/3 of a jug left.

Step-by-step explanation:

He starts with 1 1/3 jugs.

He uses 3/4 of 1 1/3 jugs.

A full amount is 1 or 4/4. If he uses 3/4, he has 1/4 left since

1 - 3/4 = 4/4 - 3/4 = 1/4

That means he has 1/4 of 1 1/3 jugs left.

We need to multiply 1/4 by 1 1/3.

1/4 * 1 1/3 =

= 1/4 * 4/3

= 4/12

= 1/3

Answer: He has 1/3 of a jug left.

Answer:

180

Step-by-step explanation:

Explanation: In a triangle, there can only be one obtuse angle. Additionally, all the angle measures must add up to 180.

Answer:

(g o f)(x) = x

Step-by-step explanation:

Given the functions f(x) = 2/x and g(x) = 2/x

(g o f)(x) = g(f(x))

g(f(x)) = g(2/x)

Replace x with 2/x in g(x)

g(f(x)) = 2/(2/x)

g(f(x)) = 2 * x/2

g(f(x)) = 2x/2

g(f(x)) = x

Hence the composite function g o f)(x) is x

Step-by-step explanation:

The solution is, A. & E. x=15/3/4.

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

here, we have,

given that,

3/4x = 15

x= 15÷3/4

x=15/3/4

Hence, The solution is, A. & E. x=15/3/4.

Answer:

number 1: {0,-6)    number 2: f(-2)=25 number 3: x=±10   number 4:B, or x=-2, x=3

number 5:36  i really hope this helps! have a good day!

Step-by-step explanation:

1: 2x^2+12x +0=0

this is how you set it up

next, you have to find the a,b,and c. This is my personal favorite way of doing this.

a=2 b=12, c=0

you plug it in to the quadratic formula which is

-b±√b^2-4ac/2a

(-12)±√(12)^2-4(2)(0)/2(2)

next you have to simplify

-12±√144-0/4

take the square root of 144

-12±12/4-

then, find the solutions of them

-12+12=0

0/4=0

x=0

we are not done yet

-12-12=-24

-24/4

x=-6

your solutions are 0,-6, which is C

2: it is giving us x, which is -2

plug in -2 to the right side of the equation.

2(-2)^2-4(-2)+9

2(4)-8+9

8-8+9

f(-2)=9

3: this one is fairly simple

x^2=100

take the square root of each side

x=±10

4: you have to replace y for 0 in this one

x^2-x-6=0

all you have to do is factor it out, and it turns into

(x+2)(x-3)

then turn these so they equal 0

x+2=0, x-3=0

x=-2     x=3

your answer would be B

5: this one is fairly simple too

the formula to completing the square is (b/2)^2

you plug in b, which is 12

12/2=6

6^2=36

you would add 36 to each side.

Answer:

7) {0, -6}

1) 25

2) x= ±10

3) x= 3, -2

4) 36

5) 225/4
