Answer 1

Answer:

1. y ⇒ ∞ as x ⇒ ∞ AND y ⇒ ∞ as x ⇒ -∞; Domain:  (-∞, ∞); Range:  [0, ∞)

2. y ⇒ -∞ as x ⇒ ∞ AND y ⇒ ∞ as x ⇒ -∞; Domain:  (-∞, ∞); Range:  (-∞, ∞)

3. y ⇒ -∞ as x ⇒ ∞ AND y ⇒ ∞ as x ⇒ -∞; Domain:  (-∞, ∞); Range:  (-∞, ∞)

4. y ⇒ ∞ as x ⇒ ∞ AND y ⇒ ∞ as x ⇒ -∞; Domain:  (-∞, ∞); Range:  [0, ∞)

Step-by-step explanation:

Rule for end behavior of polynomials:

(a) Positive leading coefficient, even degree:  y ⇒ ∞ as x ⇒ ∞ AND y ⇒ ∞ as x ⇒ -∞

(b) Negative leading coefficient, even degree: y ⇒ -∞ as x ⇒ ∞ AND y ⇒ -∞ as x ⇒ -∞  

(c) Positive leading coefficient, odd degree:  y ⇒ ∞ as x ⇒ ∞ AND y ⇒ -∞ as x ⇒ -∞

(d) Negative leading coefficient, odd degree:  y ⇒ -∞ as x ⇒ ∞ AND y ⇒ ∞ as x ⇒ -∞

Domain and range for a polynomial function with an odd degree will always be all real numbers, whether or not there's a constant or not.

Domain will always be all real numbers for a polynomial function with an even, whether or not there's a constant.

For a polynomial function with an even degree, the range will extend from the y-coordinate of the vertex to ∞, if the leading coefficient is positive

For a polynomial function with an even degree, the range will extend from -∞ to the y-coordinate of the vertex if the leading coefficient is negative.

air above you. What angle do
you need to set your Anti
Aircraft gun to hit the UFO?

Answers

In order to hit the UFO, the Anti Aircraft gun should be set an an angle of elevation of approximately 63.435° above the horizontal in the direction of the UFO

What is an angle of elevation?

An angle of elevation is an angle that the line of sight makes with the horizontal.

The location of the UFO are;

The distance of the UFO from the front of the observer (horizontal distance) = 50 feetThe distance of the UFO from above the observer (the vertical distance of the UFO) = 100 feet

The angle, θ, to which the anti aircraft gun needs to be set is found from the trigonometric ratio for tangent as follows.

[tex]tan(\theta) = \dfrac{Length \, of \, the \, side \, opposite \, to \, angle \, \theta}{Length \, of \, the \, side \, adjacent \, to \, \theta}[/tex]

The length of the side opposite to the angle θ to which the gun should be directed is the length of the height of the UFO from the observer, therefore;

Length of the side opposite to θ = 100 feet

Length of the side adjacent to θ is the length of the horizontal distance from the observer;

Length of the adjacent side to θ = 50 feet

Therefore;

[tex]tan(\theta) = \dfrac{100\, feet}{50\, feet} = 2[/tex]

tan(θ) = 2

θ is found using the inverse tangent function (arctangent) as follows;

θ = arctan(2) ≈ 63.435°

The direction the anti aircraft un should be set is at angle of elevation of approximately 63.435° above the horizontal

7 cooks

10 cooks

12 cooks

Answers

Answer:

105 Children and 3 cooks

Step-by-step explanation:

I took the test :)

a) The total number of children watching the movie is 105 children

b) The total number of cooks that worked at the event is 3 cooks

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 ,

a)

Let the number of children be = a

Let the number of adults be = b

Let the total number of people in the theater be = 140

Now , the equation will be

a + b = 140   equation (1)

And , the number of children present is 3 times the number of adults

So ,

a = 3b

Divide by 3 on both sides of the equation , we get

b = a/3

Substituting the value of b in equation (1) , we get

a + b = 140

a + a/3 = 140

( 4a ) / 3 = 140

Multiply by 3 on both sides of the equation , we get

4a = 420

Divide by 4 on both sides of the equation , we get

a = 105

Therefore , the value of a is 105 and the number of children watching the movie is 105 children

b)

Let the number of cooks be = x

Let the number of waiters be = y

Let the amount for each cook be = $ 85

Let the amount for each waiter be = $ 45

The total number of workers = 10

Now , the equation will be

x + y = 10   be equation (1)

The total amount paid to the employees be = $ 570

Now , the equation will be

85x + 45y = 570   be equation (2)

On simplifying equation (1) and equation (2) , we get

Multiply equation (1) by 45 , we get

45x + 45y = 450   be equation (3)

Subtract equation (3) from equation (2) , we get

40x = 120

Divide by 3 on both sides of the equation , we get

x = 3

Therefore , the value of x is 3 and the number of cooks that worked in the event is 3 cooks

Hence ,

a) The total number of children watching the movie is 105 children

b) The total number of cooks that worked at the event is 3 cooks

The 3rd term of a GP is 18 and the 7th term is 3⅝, find the GP

Answers

The geometric sequence in which the 3rd term is of 18 and the 7th term is of 29/8 is defined as follows:

[tex]a_n = 40(0.67)^{n - 1}[/tex]

What is a geometric sequence?

A geometric sequence is a sequence in which the result of the division of consecutive terms yields always the same result, called common ratio q.

The nth term of a geometric sequence is given by the rule presented as follows:

[tex]a_n = a_1q^{n-1}[/tex]

In which [tex]a_1[/tex] is the first term.

The rule for the nth term is also called the general rule.

The general takes the first term as the reference term, however, the 7th term can be written as a function of the 3rd term, as follows:

[tex]a_7 = a_3q^{4}[/tex]

The fraction that represents the mixed number 3 and 5/8 is:

(3 x 8 + 5)/8 = 29/8.

Then the common ratio of the sequence is calculated as follows:

[tex]\frac{29}{8} = 18q^{4}[/tex]

[tex]q^4 = \frac{29}{144}[/tex]

[tex]q = \sqrt[4]{\frac{29}{144}}[/tex]

[tex]q = \left(\frac{29}{144}\right)^{\frac{1}{4}}[/tex]

q = 0.67.

Then the first term of the sequence is obtained as follows:

[tex]a_3 = a_1q^2[/tex]

[tex]a_1 = \frac{a_3}{q^2}[/tex]

[tex]a_1 = \frac{18}{(0.67)^2}[/tex]

[tex]a_1 = 40[/tex]

Then the definition of the geometric sequence is:

***

Answers

10 kilograms of the 50% fat-content chocolate and 20 kilograms of the 20%, fat-content chocolate are used to make the required 30 kilograms.

What is an equation?

Equations are statements that affirm the equivalence of two expressions that are joined by the equals symbol "=". An equal sign ("=") links two expressions together to form an equation.

The two expressions on each side of the equals sign are referred to as the "left-hand side" and "right-hand side" of the equation. The right side of an equation is typically assumed to be zero. Since we can balance this by deducting the expression on the right from the expressions on both sides, this won't reduce the generality.

Suppose the amount of 50% fat content chocolate is x and the amount of 20% fat content chocolate is y,

Since the candy company wants to produce 30 kilograms,

x+y=30 -----(1)

If a candy manufacturer wishes to meet the dietary requirements of its customers, it may make 30 kg of special chocolate with a 30% fat content. A specific melting procedure is used to blend local chocolate with 20% fat content with foreign chocolate with 50% fat content to create this. The resultant equation reads,

50x + 20y = 30(30)

5x+2y=90 -------(2)

After solving the equation 1 and 2 we get,

x=10

y=20

Thus, 10 kilograms of the 50% fat-content chocolate and 20 kilograms of the 20%, fat-content chocolate are used to make the required 30 kilograms.

Corresponding angles are the angles that are formed when two parallel lines are intersected by the transversal. The opening and shutting of a lunchbox, solving a Rubik's cube, and never-ending parallel railway tracks are a few everyday examples of corresponding angles. These are formed in the matching corners or corresponding corners with the transversal.

∠CFH + ∠EFC = 180( angles on a straight line)

making ∠EFC subject and substituting ∠CFH = 2x + 20, we have

∠EFC = 180 - ( 2x + 20)

∠EFC = 180 - 2x -20

∠EFC = 160 - 2x

but ∠EFC = ∠BEF ( alternate angles are equal)

substituting their values

160 - 2x = 3x - 10

collect like terms

-2x - 3x = -10 - 160

-5x = -170

x = -170/-5

x = 34

Also ∠EFC = ∠AEG = 160 -2x ( corresponding angles are equal)

∠AEG = 160 -2X, but x = 34

For any function, we define the domain as the set of possible inputs, the ones in the horizontal axis, and the range as the set of the output, the ones in the vertical axis.

We can see that we have a parabola that in the bottom part has two arrows, so it extends in the wole domain (the set of all real numbers).

Instead for the range we can see that there is a maximum at y  = 4, so the range is:

R: (-∞, 4]

What is number series?

 A series is a way of speaking casually of numbers. It is the total of a sequence's terms. A series of numbers is called a number series. We must identify the laws that lead to the production of a number series in order to answer the questions about number series. The questions that might arise from these topics are as varied as these series themselves.

Here the given number series,

=> 100,90,92,82,84,74,76,….

Here , first term = 100

Second term = 100-10=90

Third term= 90+2=92

Fourth term = 92-10=82

Fifth term = 82+2=84

Sixth term = 84-10=74

seventh term = 74+2=76

Eighth term= 76-10 = 66.

Therefore next term of the number Series is 66.

A is the Point of representation of the colder midnight temperature in degrees Celsius.

The temperature in Quebec City was 5°C at 4 pm. By midnight, the temperature dropped 15 degrees.

To find out which point is a representation of the colder midnight temperature in degrees Celsius:

We know that the temperature dropped 15 degrees, and that it was initially of 5°C. So, by midnight, the temperature will be of -10°C (5-15=-10).

We also know that the distance between points is of 5°C. So, the point that we have to mark is point A, which represents -10°C.

Melanie recorded a tape of her guitar playing. It cost her $2,700 to record the master tape, and it costs $2.50 to make each copy. If she sells the tapes for $10 each, how many tapes must she sell to break even?

Answers

The number of tapes Melanie must sell to break even is 360 tapes.

How to find the number of tapes Melanie must sell to break even?

To find the number of tapes Melanie must sell to break even, we must follow these steps.

We must identify how much she earns for each tape that she sells, for this we must subtract the sale price of each tape, by the value that she pays to make each tape.

10 - 2.5 = 7.5

Now we must divide the total cost of the mother tape by the profit she makes on each tape she sells.

2,700 / 7.5 = 360

Based on the above, we can infer that she must sell 360 tapes to cover the value of the mother tape and each of the tapes that she needs to sell. Next it is checked:

360 * 10 = 3,6003,600 - 2,700 = 900900 / 2.5 = 360

From the chart, estimate (roughly) the number of transistors per IC in 2012. Using your estimate and Moore's Law, what would you predict the number of transistors per IC to be in 2040?

Answers

The estimates for the number of transistors per IC, using Moore's Law, are given as follows:

2012: 4,194,304,000.2040: 6.87 x 10¹³.

What is stated by Moore's Law?

Moore's Law states that the number of transistors per IC is expected to double every two years.

From the chart shown by the image at the end of the answer, the reference number is given as follows:

4000 transistors per IC in 1972.

The number of years between 1972 and 2012 is of:

2012 - 1972 = 40.

Hence the number of doubling periods is of:

40/2 = 20 doubling periods.

Thus the estimate for the number of transistors per IC in 2012 = 20 doubling periods is of:

4000 x 2^20 = 4,194,304,000 transistors per IC.

The number of years between 1972 and 2040 is of:

2040 - 1972 = 68.

Hence the number of doubling periods is of:

68/2 = 34 doubling periods.

Thus the estimate for the number of transistors per IC in 2012 = 20 doubling periods is of:

4000 x 2^34 = 6.87 x 10¹³ transistors per IC.

Answer:

  (-12, 10)

Step-by-step explanation:

You want to solve by elimination the system of equations ...

2x +4y = 16-2x -3y = -6

Elimination

The point of elimination is to make one of the variables disappear from the equation.

Here, we observe that the x-coefficients are opposites in the two equations. When we add them, the result is 0: the x-term disappears. Adding the two equations, we have ...

  (2x +4y) +(-2x -3y) = (16) +(-6)

  y = 10 . . . . . . . . simplified

Finding the other variable

Using this value for y, we can find x. Substituting into the first equation gives ...

  2x +4(10) = 16

  2x = 16 -40 = -24 . . . . . subtract 40 and simplify

  x = -12 . . . . divide by 2

The ordered pair that is the solution is (x, y) = (-12, 10).
