Which Mapping Diagram Does Not Represent A Function?

Answers

Answer 1

Answer:

A.

Step-by-step explanation:

The definition of a function is that each input has only 1 output. That does not mean that 2 different inputs can not have the same output. A. shows that the number 3 has 2 outputs. My explaining is not that good but trust me.

A spherical balloon is being inflated with helium at a rate of 20π cm3/min. How fast is the balloon's radius changing when the radius is 1 cm?

Answers

Answer:

5 cm/min

Step-by-step explanation:

A spherical balloon is being inflated with helium at a rate of 20π cm³/min.

The volume of a sphere is given by :

[tex]V=\dfrac{4}{3}\pi r^3[/tex] ...(1)

Differentiate equation (1) wrt t as follows :

[tex]\dfrac{dV}{dt}=3\times \dfrac{4}{3}\pi r^2\times \dfrac{dr}{dt}\\\\\dfrac{dV}{dt}=4\pi r^2\dfrac{dr}{dt}\ ....(1)[/tex]

Put dV/dt = 20π cm³/min and r = 1 cm, we can fin dr/dt

[tex]\dfrac{dV}{dt}=4\pi r^2\dfrac{dr}{dt}\\\\20\pi =4\pi (1)\times \dfrac{dr}{dt}\\\\\dfrac{dr}{dt}=5\ cm/min[/tex]

So, the radius of changing at the rate of 5 cm/min.

Using implicit differentiation, it is found that the radius is changing at a rate of 5 cm/min.

The volume of a sphere of radius r is given by:

[tex]V = \frac{4\pi r^3}{3}[/tex]

Applying implicit differentiation, the rate of change is of:

[tex]\frac{dV}{dt} = 4\pi r^2\frac{dr}{dt}[/tex]

A spherical balloon is being inflated with helium at a rate of 20π cm3/min, hence [tex]\frac{dV}{dt} = 20\pi[/tex]The radius is of 1 cm, hence [tex]r = 1[/tex].

Then:

[tex]\frac{dV}{dt} = 4\pi r^2\frac{dr}{dt}[/tex]

[tex]20\pi = 4\pi (1)^2\frac{dr}{dt}[/tex]

[tex]\frac{dr}{dt} = \frac{20}{4}[/tex]

[tex]\frac{dr}{dt} = 5[/tex]

The radius is changing at a rate of 5 cm/min.

Answer the following questions based on the graphic given below.

The person casts a shadow ___ feet long.
The building casts a shadow ___ feet long.
The ratio of the person’s shadow to the building’s shadow is ___ to ___.
If the other side of the building is 10 feet tall, the person will be ___ feet tall.

Answers

Answer:

The person casts a shadow 3 feet long.

The building casts a shadow 15 feet long.

The ratio of the person’s shadow to the building’s shadow is 1 to 5.

If the other side of the building is 10 feet tall, the person will be 2 feet tall.

(I'm not sure what the last question meant by "the other side of the building". I assume it means the height of the building? 2 feet tall seems a bit short for a person though, but that would be correct since the building's height is 2/3 of the shadow's length, and 2/3 of the person's shadow length, 3, is 2 feet)

The building, the person and their shadows form a right triangle; The texts that complete the blanks are 3 feet long, 15 feet long, 1 to 5 and 2 feet tall.

What is a right triangle?

A right triangle is a triangle that has an angle of 90 degrees

From the question, we have the following highlights:

Person's shadow = 3 feetBuilding's shadow = 15 feet

So, the ratio of the person’s shadow to the building’s shadow is

Ratio = 3 feet : 15 feet

Simplify

Ratio = 1 : 5

When the building's height is 10 feet, we have:

Person : 10 feet = 1 : 5

Multiply by 2 feet

Person : 10 feet = 2 feet : 10 feet

By comparison, we have:

Person = 2 feet

Hence, if the other side of the building is 10 feet tall, the person will be 2 feet tall.

The graph second representing the complex number 2(cos(2π/3)+i sin(2π/3)) on a coordinate plane option second is correct.

What is a complex number?

It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.

The complete question is:

Which graph represents 2(cos(2π/3)+i sin(2π/3))?

The graphs are in the picture, please refer to the picture.

We have a complex number;

= 2(cos(2π/3)+i sin(2π/3))

= 2(cos120 + i sin120)

= 2(-0.5 + i 0.866)

= -1 + i 1.732

The point is (-1, 1.732)

Thus, the graph second representing the complex number 2(cos(2π/3)+i sin(2π/3)) on a coordinate plane option second is correct.

Answers

Answer:

96

Step-by-step explanation:

Given that :

Standard deviation (s) = 2km

Error in estimation is within 0.4 km ; Error (E) = 0.4 km

Using the relation :

Sample size = ((Zα/2 * s) /E)^2

Using α = 0.05

The Zcritical at 0.05 = Z0.025 = 1.96

Sample size = ((1.96 * 2) / 0.4)^2

Sample size = (3.92 / 0.4)^2

Sample size = 9.8²

Sample size = 96.04

Required sample size = 96

A 5-ounce can of tuna costs $0.90. A 12-ounce can of tuna costs $2.40. Which is the better buy?

Answers

Answer:

To find out which one is the better buy we have to find out what the unit price of each one is.  To find a  unit price you divide the ounce by the cost.

Step-by-step explanation:

5/90=18 cents

12/240=5 cents

the 12 ounce can is less per ounce so the 12 ounce can is the better buy.

Asa's most recent credit card statement had a balance of $2,622.77. The minimum payment warning box indicates that it will take 12 years to pay off the card if
be makes the minimum payment of $28 per month. If he makes a monthly payment of $100, it will take 3 years to pay off the balance. What will be the percent
increase in total payments if Asa only pays the minimum rather than the $100 per month?

Answers

Answer:

12%

Step-by-step explanation:

In order to calculate this we first need to find the total that she would pay if she were to choose either of these options. We do this by multiplying the number of years it would take to pay off the loan by the 12 months in a year, and then we multiply this product by the monthly payment like so...

Minimum Payment:

(12 * 12) * 28 = $4,032

$100 a month payment:

(12* 3) * 100 = $3,600

Now that we have both we need to divide the minimum payment total by the $100 a month payment total to get the percentage increase in decimal form

$4,032 / $3,600 = 1.12

Now we subtract 1 and multiply by 100 to turn this decimal into a percentage

(1.12 - 1) * 100 = 12%

Finally, we can see that if Asa only pays the minimum then she would be paying a 12% increase as opposed to paying the $100 a month
