Step-by-step explanation:

Divisor = -2n = -2 * 6 = - 12

Dividend = 3 + ( 4 * 6 - 6) = 3 + 18 = 21

Now

21 / -12

dividing numerator and denominator by 3

= - 7 / 4

Step-by-step explanation:

= -2n

= -2×6

= -12

again,

=3+(4n-n)

= 3+4×6-6

=3+24-6

=21

Step-by-step explanation:

we know that The area of a Kite is equal to where D1 and D2 are the diagonals of the kite In this problem we have Substitute in the formula and solve for D2 therefore the answer is the option B  

The measure of the other diagonal is 6.8 inches. The correct option is the second option 6.8 inches

From the question, we are to determine the measure of the other diagonal

If a kite has diagonals p and q, then the area of the kite is given as

\(A =\frac{pq}{2}\)

Where A is the area of the kite

From the given information,

One of diagonal measures 15.2 inches

Let p = 15.2 inches

and

A = 51.68 square inches

Putting the parameters into the formula, we get

\(51.68 = \frac{15.2 \times q}{2}\)

Then,

15.2 ×q = 51.68 × 2

15.2q = 103.36

q = 103.36 ÷ 15.2

q = 6.8 inches

Hence, the measure of the other diagonal is 6.8 inches. The correct option is the second option 6.8 inches

To determine whether the furnace will be adequate for a 1,400 square foot house with a 9-foot ceiling, we need to calculate the volume of the house and compare it to the volume the furnace is designed to heat.

The volume of the house can be found by multiplying the square footage by the ceiling height:

1,400 sq ft x 9 ft = 12,600 cubic feet

Since the furnace is designed to heat 10,000 cubic feet, and the house has a volume of 12,600 cubic feet, the furnace may not be adequate for heating the house. The furnace is not capable to heat the entire house.

Answer:

A)

Function A: Exponential

Function B: Linear

Function C: Exponential

Function D: Exponential

B) Function A

Step-by-step explanation:

Function A: This is exponential because- (1, 3)(2,9)(3,27)

It is not going up by the same number each time. However, it is multiplying by 3 each time which means it is exponential.

Function B: This is linear because- (1, 64)(1, 80)(1, 96)

It is going up by 16 each time, (a constant number) which means it is linear.

Function C: This is exponential because- there is a curve, linear is always a straight line. But, this has a curve which means it is exponential.

Function D: This is exponential because- It is increasing by a percentage and not a constant number. It is increasing by 1% which means it is exponential.

The function that has the greatest growth factor is Function A because, Function A multiplies by 3 each time. Function B is linear, exponential functions always pass linear functions despite how "steep" they are. Eventually, the exponential function will surpass it. Function C is also exponential but is not as "steep" as Function A. Function A multiplies by 3 each time but Function C increases less. Function D is also exponential, and for the same reasons as Function C, Function A has the greatest growth factor.

B) The equation for vertical asymptote is x = 4 and the equation for horizontal asymptote is y = 0.

C) The domain and range of f are:

Domain = [-∞, 4) U [4, ∞]

Range = [0, ∞]

In Mathematics, the x-intercept is the point at which the graph of a function crosses or touches the x-coordinate and the y-value or value of "y" is equal to zero (0).

Part A.

Based on the graph of this rational function, the x-intercept and y-intercept include the following:

x-intercept: none.

y-intercept: 1.

Part B.

An equation that represents the vertical asymptote is x = 4 while the equation represents the horizontal asymptote is y = 0 because the line does not cross those points.

Part C.

By critically observing the graph of this rational function, we can logically deduce the following domain and range:

Domain = [-∞, 4) U [4, ∞] or {x|x ≠ 4}.

Range = [0, ∞] or {y|y ≥ 0}.

There are 540 men living in the mini city.

x + (x + 150) = 1230

Simplifying this equation, we get:

2x + 150 = 1230

Subtracting 150 from both sides, we get:

2x = 1080

Dividing both sides by 2, we get:

x = 540

Therefore, there are 540 men living in the mini city.

To check our answer, we can substitute x = 540 into our original equation:

540 + (540 + 150) = 1230

690 = 1230

This is false, so there must be an error in our calculation. We can double-check our work by trying a different approach.

We know that the number of women exceeds the number of men by 150, so we can represent the number of women as (x + 150). We also know that the total number of people is 1230, so we can set up an equation:

x + (x + 150) = 1230

Simplifying this equation, we get:

2x + 150 = 1230

Subtracting 150 from both sides, we get:

2x = 1080

Dividing both sides by 2, we get:

x = 540

Answer:

q = -2

Step-by-step explanation:

Constant = whole number

If the two lines are parallel the slopes would be equal.

So if the first line is y = -2x + 5/3

The the second line would become y = -2x + 6.

If q becomes -2, it will be a constant and the two lines will also be parallel

The slowest time of the 40 yard dash is given by the equation A = 3.41 sec

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 slowest time be represented as A

Now , the equation will be

Let the total length of the yard = 40 yard dash

Let the fastest time be represented as F

The value of F = 4.58 seconds

The difference between the fastest and the slowest time = 1.17 seconds

Substituting the values in the equation , we get

Fastest time - slowest time = 1.17 seconds

So ,

4.58 - A = 1.17

On simplifying the equation , we get

Adding A on both sides of the equation , we get

A + 1.17 = 4.58

Subtracting 1.17 on both sides of the equation , we get

A = 4.58 - 1.17

A = 3.41 seconds

Therefore , the value of A is 3.41 seconds

the center of the given ellipse is (-1, 1).Hence, the required answer is (-1, 1).

The given equation of the ellipse is

100pts9x²+4y²+18x - 8y-23=0.

To find the center of the ellipse, Rearrange the given equation of the ellipse to standard form by completing the square. To complete the square for x terms, we need to add

(18/2)²=9²=81

to both sides of the equation. To complete the square for y terms, we need to add

(-8/2)²=4²=16

to both sides of the equation.

100pts9x²+18x+4y²-8y=23+81+16-100pts100pts(9x²+18x+81) + 100pts(4y²-8y+16) = 120100pts(3x+3)² + 100pts(2y-2)² = 120 + 100pts100pts3(x+1)² + 100pts2(y-1)² = 180

Answer:

Center = (-1, 1)

Step-by-step explanation:

To find the center of the ellipse, we first need to write the equation in its standard form by completing the square.

Given equation:

\(9x^2+4y^2+18x-8y-23=0\)

Arrange the equation so that all the terms with variables are on the left side and the constant is on the right side.

\(9x^2+18x+4y^2-8y=23\)

Factor out the coefficient of the x² term and the coefficient of the y² term:

\(9(x^2+2x)+4(y^2-2y)=23\)

Add the square of half the coefficient of x and y inside the parentheses of the left side, and add the distributed values to the right side:

\(9(x^2+2x+1)+4(y^2-2y+1)=23+9(1)+4(1)\)

Factor the two perfect trinomials on the left side and simplify the right side:

\(9(x+1)^2+4(y-1)^2=36\)

Divide both sides by 36 so the right side equals 1:

\(\dfrac{9(x+1)^2}{36}+\dfrac{4(y-1)^2}{36}=\dfrac{36}{36}\)

\(\dfrac{(x+1)^2}{4}+\dfrac{(y-1)^2}{9}=1\)

The standard form of the equation of an ellipse with center (h, k) is:

\(\boxed{\dfrac{(x-h)^2}{a^2}+\dfrac{(y-k)^2}{b^2}=1}\)

Comparing the rewritten equation with the standard equation, we can determine that h = -1 and k = 1.

Therefore, the center (h, k) of the ellipse is (-1, 1).

In everyday terms, an average is one number chosen to represent a list of numbers; it is typically the sum of the numbers divided by the number of numbers in the list (the arithmetic mean). The average of the numbers 2, 3, 4, 7, and 9 is, for instance, 5. An average could be another statistic like the median or mode depending on the situation.

Because the mean would be higher if the personal incomes of a few billionaires were included, the median—the amount below which 50% of personal incomes fall and above which 50% of personal incomes rise—is frequently used to represent the average personal income. It is advised to avoid using the word "average" when discussing measures of central tendency because of this.

Given:

80% of the test = 32 questions

100% of the test = x questions

Cross multiply

80*x = 100 * 32   Combine the right
