determine the zeros & the y-intercept of the function 3(x-3)(x-2)

Answers

Answer:

see explanation

Step-by-step explanation:

Given

y = 3(x - 3)(x - 2)

To find the x- intercepts, let y = 0, that is

3(x - 3)(x - 2) = 0

Equate each factor to zero and solve for x

x - 3 = 0 ⇒ x = 3

x - 2 = 0 ⇒ x = 2

Thus the x- intercepts are x = 2 and x = 3

To find the y- intercept let x = 0 and equate for y, that is

y = 3(0 - 3)(0 - 2) = 3(- 3)(- 2) = 3 × 6 = 18

Thus the y- intercept is y = 18

Answers

Transformation involve moving a point away from its original location.

The vertices of the pre-image are (–1, 0) and (–1, –5).

How does transformation of a function happens?

The transformation of a function may involve any change.

Usually, these can be shift horizontally (by transforming inputs) or vertically (by transforming output), stretching (multiplying outputs or inputs) etc.

The rule is given;

[tex]r_{y = x} T_{4,0(x,y)}[/tex]

The rule means that

ABCD was translated by 4 units to the right, then reflected over line y = x,

The rule of right translation by 4 units,

(x, y) --- (x+4, y)

The rule of reflection over,

(x, y) --- ( y, x+ 4)

The coordinates of A"B"C"D" are: (-4, 5), (-1, 5), (0, 3), (-5, 3).

Hence, the vertices of the pre-image are (–1, 0) and (–1, –5).

5. Celia gets paid biweekly. Her biweekly salary is $1,763.28. What is her annual
salary?

Answers

Answer:

Her annual salary is $45,845.28

Step-by-step explanation:

Multiplication is the process of multiplying. Celia' s annual salary is $48,845.28.

What is multiplication?

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

Given that Celia's biweekly salary is $1,763.28. Therefore, her weekly salary will be,

Celia's weekly salary = Celia's biweekly salary/ Number of weeks

Biweekly mean once in two weeks, therefore,

Celia's weekly salary = $1,763.28 / 2 weeks

Celia's weekly salary = $881.64 per week

Now, a complete year has 52 weeks, therefore, Celia's annual salary will be,

Celia's annual salary = Celia's weekly salary × Number of weeks in a year

                                   = $881.64 per week × 52 weeks

                                   = $48,845.28

Hence, Celia' s annual salary is $48,845.28.

how do you factorise 18x² + 9x?

please show the steps an answer fully, please​

Answers

Answer:

9x(2x + 1)

Step-by-step explanation:

Looking at the two terms, notice that you can write the first term as:

18x² = 9x * 2x

Then, we can see that the first term and second term both have 9x in them. That means 9x is a common factor, so we can take it out from both of them ("take it out" basically means "divide"):

18x² + 9x = 9x * 2x + 9x = 9x * (2x + 1)

Thus, the factored form is 9x(2x + 1).

Hey there,

The first step in solving this problem would have to be to add the two binomials together:

10x² - 4x

Knowing this now we find the GCF which would have to be 2x which goes into both terms.

The factored form would have to be 2x(5x - 2).

The GCF is 2x and the factored form is 2x(5x - 2).

Hope I helped,

Amna

The GCF for the expression (6x2 + 4x) + (4x2 - 8x) is 2x, and the expression in factored form is 2x(5x - 2).

To determine the greatest common factor (GCF) and write the expression in factored form for (6x2 + 4x) + (4x2 - 8x), we should first combine like terms:

6x2 + 4x + 4x2 - 8x = 10x2 - 4x

We can then identify that both terms have a common factor of 2x. Factoring that out, we get:

2x(5x2/2x - 4/2) = 2x(5x - 2).

Use 3.14 for LaTeX: \piπ.

Round to the nearest hundredth.

Answers

Given:

The height of the given fig = 7.5 unit

The radius of the given fig = 3.6 unit

To find the volume of the given composite figure.

Formula

The volume of the given fig

[tex]V = V_{1}+V_{2}[/tex]

where,

[tex]V_{1}[/tex] be the volume of the cone

[tex]V_{2}[/tex] be the volume of the semicircle

[tex]V_{1}=\pi r^{2} h[/tex], r be the radius and h be the height

[tex]V_{2} = \frac{2}{3} \pi r^{3}[/tex], r be the radius

Now,

Putting, r= 3.6, h = 7.5 and π = 3.14 we get,

[tex]V_{1} =(3.14)(3.6^{2} )(7.5)[/tex] cube in

or, [tex]V_{1}= 305.208[/tex] cube in

And,

[tex]V_{2} =\frac{2}{3} (3.14)(3.6^{3})[/tex] cube in

or, [tex]V_{2} = 97.67[/tex] cube in

So,

[tex]V = 305.208+97.67[/tex] cube in

or, [tex]V = 402.878[/tex] = 402.88 cube in

Hence,

The volume of the given figure is 402.88 cube in.

Answer: Either spinner

Step-by-step explanation: I hope this makes sense, as I had the same question :)

I  would choose either spinner because there is an equally likely probability to land on a greater number using  either one.  If you join the same numbers together on spinner 1 (all the 1's together, 2's together,  and 3's together), the section they would make would be the same size as that same number section on spinner 2.  

OR (more detailed one)-

The probability of landing on a number greater than your friend on either spinner is equally likely. 1 and 2 on the first spinner are both 3/8 of the spinner and 3 is 2/8 which is the same ratios as the second spinner. The difference is that on spinner #1, the numbers are split up and spread out from each other (ex. 1,2,3,2,3,1), and in spinner #2 all the 1's, 2's, and 3's are together to make bigger looking chunks. The area of each number is the same on both spinners.

Kareem drove 225 miles using 10 gallons of gas. At this rate, how many gallons of gas would he need to drive 441 miles?
how many gallons

Answers

Answer:

19.6 gallons

Step-by-step explanation:

If 10 gallons of gas were used to drive 225 miles then If kareem drove on 1 gallon of gas would take 22.5 miles.

so 1 gallon=22.5 miles,441 miles=19.6 gallons because,441/22.5=19.6 gallons.

The Kareem 19.56 gallons of gas to drive 441 miles at the same rate.

To find the number of gallons Kareem to drive 441 miles at the same rate, set up a proportion based on the given information:

Miles driven / Gallons of gas = Miles to be driven / Gallons of gas

Using the values provided:

225 miles / 10 gallons = 441 miles / x gallons

cross-multiply to solve for x:

225x = 10 ×441

Dividing both sides of the equation by 225:

x = (10 ×441) / 225

The two denominators are not equal, so the quotients cannot be equal.

P(A|D) and P(D/A) are not equal because the total number of A and D are not equal.

What is Probability?

It is a branch of mathematics that deals with the occurrence of a random event.

From the table, we have the following parameters:

n(A) = 8

n(D) = 10

n(A and D) = 2

P(A|D) and P(D|A) are both conditional probabilities, and they are calculated using:

P(A|D)=2/10

=1/5 = 0.2

P(D/A)= 2/8

=1/4

From the above computations, we have:

P(A|D)≠P(D/A)

A gardener has a circular garden, which he divides into four quadrants. He has four different kinds of flowers, and he wants to assign a flower to each quadrant, so that adjacent quadrants are not planted with the same kind of flower. (Also, the gardener can use the same flower more than once.) How many different gardens are possible?

Answers

Answer:

84

Explanation:

Call the quadrants I, II, III, and IV, counterclockwise, and the kinds of flowers A, B, C, and D.

Start by assigning a flower of kind A to quadrant I.

Then, quadrant II can have flower B, C, or D.

If it is B, then quadrant III can have either A, C, or D. If it is

If quadrant III has A, then quadrant IV can have either B, C, or D. That is 3 different gardens.

If quadrant III has C, then quadrant IV can have either B or D. That is 2 different gardens.

If quadrant III has D, then quadrant IV can either either B or C. That is 2 different gardens.

Those are all the possible different gardens if A is assigned to quadrant I and B is assigned to quadrant II: 3 + 2 + 2 = 7.

Working yet with A in quadrant I but assigning C to quadrant II, you can make the same reasoning as above to get other 7 gardens.

The same with A in quadrant I but D in quadrant II, other 7 different gardents.

In total, you find 7 × 3 = 21 different gardens when flowers of kind A are assingned to quadrant I.

Starting with a flower of kind B in quadrant I, there will be other 21 different gardens. The same for C and D. Then, in total, there are 4 × 21 = 84 different possible gardens.

Answer:

84

Step-by-step explanation:

Quadrants A and C either have the same kind of flower, or they have different flowers.

If quadrants A and C have the same kind of flower, there are 4 ways to choose this flower. There are then 3 ways to choose the flower for quadrant B, and 3 ways to choose the flower for quadrant D, so there are 4 x 3 x 3 = 36 possible ways in this case.

If quadrants A and C have different kinds of flowers, then there are 4 ways to choose the flower for quadrant A, then 3 ways to choose the flower for quadrant C. Then there are 2 ways to choose the flower for quadrant B, and 2 ways to choose the flower for quadrant D, so there are 4 x 3 x 2 x 2 = 48 possible ways in this case.

Therefore, there are a total of 36 + 48 = 84 ways to plant the flowers.

Find the exact length of the third side.

Answers

Answer:

The third side is sqrt(5)

Step-by-step explanation:

This is a right triangle so we can use the Pythagorean theorem

a^2+b^2 = c^2  where a and b are the legs and c is the hypotenuse

We know the legs are 1 and 2 and we are looking for the hypotenuse.

1^2+2^2 = c^2

1+4 = c^2

5 =c^2

Take the square root of each side

sqrt(5) = sqrt(c^2)

sqrt(5) =c

Step-by-step explanation:

Data

Right triangle

hypotenuse = 24

Opposite side = 15

Adjacent side = ?

Process

1.- Calculate the adjacent side using the Pythagorean theorem.

          hypotenuse² = opposite side² + adjacent side²

-Solve for adjacent side

          Adjacent side² = hypotenuse² - opposite side²

-Substitution

           Adjacent side² = 24² - 15²

-Simplification

           Adjacent side² = 576 - 225

           Adjacent side = 351

-Result

           Adjacent side = 18.73°

2.- Find the value of x°

a) Using sin x

              sinx = Opposite side/Hypotenuse = 15/24 = 0.625

                  x = 38.68°

b) Using cos x

              cos x = Adjacent side/Hypotenuse = 18.73/24 = 0.78

              cos x = 38.68°

c) Using tan x

              tanx = Opposite side / Hypotenuse = 15/18.73 = 0.80

Write the fractional notation in lowest terms.
110 minutes to 4 hours.

Answers

It will be 27 mins to 2 hours I think

Final answer:

To convert 110 minutes to a fraction of 4 hours, we first turn both quantities into minutes and then form a fraction. Reducing this fraction to its lowest terms, 110 minutes to 4 hours can be expressed as the fraction 11/24.

Explanation:

To express 110 minutes in terms of hours, we need to divide the number of minutes by 60, since there are 60 minutes in an hour.

110 minutes ÷ 60 minutes = 1 hour 50 minutes

Now we have to represent 1 hour 50 minutes as a fraction of 4 hours. First, let’s convert 1 hour 50 minutes entirely to minutes to make it easier to compare. There are 60 minutes in an hour, hence:

1 hour = 60 minutes
50 minutes = 50 minutes
Total minutes = 60 + 50 = 110 minutes

Since we know 4 hours is the same as 240 minutes (4 hours x 60 minutes/hour), we can now write the fractional notation:

110 minutes / 240 minutes

Reducing this fraction to lowest terms by dividing both the numerator and the denominator by 10 yields:

11 / 24

Therefore, 110 minutes to 4 hours is expressed as the fraction 11/24 in lowest terms.

Which function is the inverse of f(x) = 2x + 3?

Answers

Answer:

y = 1/2x - 3/2

Step-by-step explanation:

The easiest way to find the inverse is to switch x and y and solve for y.

y = 2x + 3

x = 2y + 3 (Switch)

x-3 = 2y (Subtract y from both sides)

x/2 - 3/2 = y (Divide both sides by 2)

Answer:

The inverse is 1/2x -3/2

Step-by-step explanation:

y = 2x+3

To find the inverse, exchange x and y

x = 2y+3

Solve for y

Subtract 3 from each side

x-3 = 2y+3-3

x-3 =2y

Divide each side by 2

x/2 -3/2 = 2y/2

1/2x -3/2 =y

The inverse is 1/2x -3/2
