Explain why the function is not continuous at x= -5

Answers

For the function,

F(x)  = (x² + 11x +28)/(x² + 8x + 15) limit doesn't exist at x = -5 so it is dis-continuous at that point.

What is continuity ?

In mathematics, The function is called as continuous at the particular value of x,  if right hand limit, left hand limit and the value of function at x all are equal.

RHL   = LHL  = F(x)

Limit exist and continuous

Given that,

F(x)  = (x² + 11x +28)/(x² + 8x + 15)

To check whether it is continuous at x = -5

First taking LHL,

[tex]\lim_{h \to \ 0}[/tex] [(-5-h)² + 11(-5 -h) +28]/[(-5 -h)² + 8(-5 -h) + 15]

It is approaching at negative infinity

Now, taking RHL

[tex]\lim_{h \to \ 0}[/tex]  [(-5+h)² + 11(-5 +h) +28]/[(-5 +h)² + 8(-5+h) + 15]

Again, It is approaching at negative infinity

Hence, here limit doesn't exist so it is not continuous at x = -5

The volume of the composite figure is 117π ft³ or 368 ft³

How to find the volume of a composite figure?

The figure shown is made up of a hemisphere and a cylinder.

Total volume of the figure = volume of hemisphere + volume of cylinder

Formula for the Volume of the hemisphere is;

V = ⅔πr³

Radius (r) of hemisphere = 6/2 = 3 ft

Volume of hemisphere = ⅔ * π * 3³

= 18π ft³

Volume of Cylinder is given by the formula;

V = πr²h

radius (r) = 3 ft

height (h) = 11 ft

Volume of cylinder = π * 3² * 11

= 99π ft³

Volume of the figure = 18π ft³ + 99π ft³ = 117π ft³

Among 60 students the probability that the group plays Field Hockey (F) and Basketball (B) is 0.083.

What is probability?

Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can range from 0 to 1, with 0 denoting an impossibility and 1 denoting a certainty.

From the given Venn Diagram -

The number of students who play Field Hockey (F) is = 18

The number of students who play Soccer (S) is = 10

The number of students who play Basketball (B) is = 7

The number of students who play Field Hockey (F) and Soccer (S) is = 4

The number of students who play Field Hockey (F) and Basketball (B) is = 2

The number of students who play Soccer (S) and Basketball (B) is = 5

The number of students who play Field Hockey (F), Soccer (S) and Basketball (B) is = 3

The number of students who play nothing = 11

The probability to find the students who play  Field Hockey (F) and Basketball (B) is -

Probability = (number of students who play Field Hockey (F) and Basketball (B)) + (number of students who play Field Hockey (F), Soccer (S) and Basketball (B)) / (Total number of students in survey)

Substitute the values in the equation -

Probability = (2 + 3) / 60

Probability = 5 / 60

Probability = 1 / 12

Probability = 0.083

Therefore, the probability value is obtained as 0.083.

Answers

If Eris Orbit. The recently discovered Eris orbits the Sun every 557 years.

Its average distance (semimajor axis) from the sun is: 67.7 AUDifference between the two dwarf planets is 28.2 AU

What is its average distance (semimajor axis) from the sun?

In order to calculate the semimajor axis of Eris, we need to plug 557 years into the equation
a=P^2/3

a= 557^0.66666667

a = 67.6971 astronomical units.

a = 67.7 AU (Rounded)

Since the average distance for Pluto from the Sun is 39.3 AU

So,

Since the distance of Eris to the sun is 67.7 AU and Pluto to the sun is 39.5

Difference between the two dwarf planets = 67.7AU - 39.5 AU

Difference between the two dwarf planets = 28.2 AU

Based on the above calculation Eris is about 1.5 times farther from the Sun in comparison to Pluto.

On solving the equations x + y + z = 6400 and 0.08x + 0.096y + 0.144z = 744, the values for first, second and third investments are $1500, $1700 and $3200 respectively.

What is an equation?

A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").

Susan places $6400 in three investments at rates of 8%, 9.6% and 14.4% per annum, respectively.

Let the amount of each investment be x, y and z.

So the mathematical form of the statement is -

x + y + z = 6400

The total income after one year is $744.00.

So the mathematical form of the statement is -

0.08x + 0.096y + 0.144z = 744

The amount placed in the third investment is $1500 more than the amount placed in the second.

So the mathematical form of the statement is -

z = (y + 1500)

Substitute the value of z in first equation -

x + y + (y + 1500) = 6400

x + 2y = 6400 - 1500

x + 2y = 4900

x = (4900 - 2y)

Substitute the value of z in second equation -

0.08x + 0.096y + 0.144(y + 1500) = 744

0.08x + 0.096y + 0.144y + 216 = 744

0.08x + 0.24y = 744 - 216

0.08x + 0.24y = 528

Substitute the value of x in this equation -

0.08(4900 - 2y) + 0.24y = 528

392 - 0.16y + 0.24y = 528

- 0.16y + 0.24y = 528 - 392

0.08y = 136

y = 136/0.08

y = 1700

Therefore, the value of second investment is 1700.

Substitute the value of y in formula for z -

z = (y + 1500)

z = 1700 + 1500

z = 3200

Therefore, the value of third investment is 3200.

Substitute the value of y in formula for x -

x = (4900 - 2y)

x = 4900 - 2(1700)

x = 4900 - 3400

x = 1500

Therefore, the value of first investment is 1500.

Answers

The sale price of the item is given by the equation A = $ 22.40

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

The regular price of the item = $ 28.00

The percentage of discount = 20 %

So , the sale price of the item = regular price of the item  - ( percentage of discount x regular price of the item  )

Substituting the values in the equation , we get

The sale price of the item A = 28.00 - ( 0.20 ) x 28.00

The sale price of the item A = 28.00 ( 1 - 0.20 )

The sale price of the item A = 28.00 ( 0.80 )

So , the sale price of item is 80 percentage of the regular price

Therefore , the sale price of the item = ( 80 / 100 ) x $ 28.00

The sale price of the item A = $ 22.40

Hence , the sale price is $ 22.40
