Create the polynomial which has roots 3and 2

Answers

Answer:

f(x) = x² - 5x + 6

Step-by-step explanation:

Given a root of a polynomial x = a then the factor is (x - a)

Here the roots are x = 3 and x = 2 , thus the corresponding factors are

(x - 3) and (x - 2)

The polynomial is then the product of the factors, that is

f(x) = (x - 3)(x - 2) ← expand using FOIL

      = x² - 5x + 6

Since this polynomial has answers 3 and 2, we can set up the equation (x-3)(x-2) = 0

That’s already our answer, but if you want it in standard form, We can use FOIL to multiply the 2 expressions:
(x-3)(x-2)
=x^2-3x-2x+6
=x^2-5x+6

2x – 3 > 2(x-5)

Which of the capital letters G, I, J, L, or Q has at least one line of symmetry?

Answers

I is the right one because it is a half and they both look the same

Letters that have lines of symmetry is : I

What is reflectional symmetry?

Consider a plane. Let a design or shape on that plane. Now consider an axis. If we think of that axis as a mirror, and on the opposite side of that axis create the image of the shape, then if the shape's image looks exactly as the shape itself, then that shape is called to have a reflectional symmetry.

The lines of symmetry can be found as vertical or horizontal. Letters O, H, I. X have 2 lines of symmetry and other have 1.

At least one line of symmetry have letters:

A, B, C, D, E, H, I, M, O, T, U, V, W, X, Y ( you can choose one ).

The letter G has a no axis of symmetry and letter L has a horizontal axis of symmetry.

The letter I is the right one because it is a half and both look the same.

A bag contains three blue marbles, five red marbles, and four green marbles.

Part A: What is the probability of selecting a red marble?

Part B: What is the probability of selecting three red marbles without replacement?

Part C: In a short paragraph, explain in your own words your work to Step B

Answers

Answer:

Below.

Step-by-step explanation:

The total number of marbles is 12.

Part A.

Prob(Red marble) = 5/12.

Part B.

Prob(pick 3 red marbles without replacement) = 5/12 * 4/11 * 3/10 = 1/22.

Part C.

The probability of the first being red is 5/12 because there are 5 red out of a total of 12 marbles. After that there are only 4 marbles and the total is 11 ( 1 marble less). Finally on the 3rd pick there are 3 red and a total of 10. WE then multiply these 3 probabilities.

Tammy buys a 4-gigabyte memory card for her camera. Dijonea buys a memory card with twice as much storage as Tammy’s. One gigabyte is 1,024 megabytes. How many megabytes of storage does Dijonea have on her memory card?

Answers

Answer:

Dijonea have 8192  megabytes on her memory card

Step-by-step explanation:

Capacity of Tammy's memory card =  4-gigabyte

given that Dijonea buys a memory card with twice as much storage as Tammy’s

Thus,

Capacity of Dijonea's memory card =  2*Capacity of Tammy's memory card

Capacity of Dijonea's memory card =  2*4-gigabyte = 8-gigabyte

Given that

1 gigabyte = 1,024 megabytes

we have to find value of 8 gigabyte in terms of megabytes

for that we multiple both side in above equation by 8

1 *8 gigabyte = 1,024 *8 megabytes

8 gigabyte = 8192  megabytes

Thus, Dijonea have 8192  megabytes on her memory card

a.) no real solution.
b.) x= 7
c.) x= -7
d.) x= -7 and x= 7

Answer:

C

Step-by-step explanation:

-7 squared is -49, -49 plus 49 is 0.

(-7)^2=49 and 7^2=49
No matter what you plug in for x, squaring it will make it come back positive. Therefore it will be impossible to get -49+49=0. So there is no solution.

The length of a rectangle is eight centimeters less than twice its width. If the perimeter of
the rectangle is 20 centimeters, find its dimensions.

Answers

Answer:

width of given rectangle = 6 cm

length of given rectangle =  4 cm

Step-by-step explanation:

Let the breadth be x cm

given that

The length of a rectangle is eight centimeters less than twice its width

length of rectangle in terms of x =  2(breadth ) - 8 =  2x - 8

we know perimeter of rectangle is given = 2(l + b)

thus, perimeter of given rectangle is = 2 ( x +  2x - 8) = 6x - 16

also given perimeter of the rectangle is 20 centimeters

thus,

6x - 16 = 20

6x = 20 + 16 = 36

x = 36/6 = 6

Thus,

width of given rectangle = 6 cm

length of given rectangle = 2*6 - 8 = 4 cm

Answers

Answer:

243

Step-by-step explanation:

the reason why it's 243 is because 3 x 3 = 9, 9 x 3 = 27, and 81 x 3 = 243.

Answer: Step-by-step explanation: 243

Lets look at the difference between the first two numbers (3 and 9). to get from 3 to 9, we either have to multiply by 3, or add 6.

Next, let's look at the difference between 9 and 27. to get from 9 to 27, you have to multilpy by 3, or add 18.

If we conitnue to multiply the previous by 3, we get the following number, therefore we know the answer is to multiply by 3.

if we multiply 81 by 3, we get 243

Find the value of w. (5w+3)

Answers

we can find the value of w by making it equal to 0:
5w+3 = 0
5w = -3 <- subtract 3 from both sides
w = -3/5 <- divide 5 from both sides

w = -3/5 is your final answer!
hope this helps

The solution is: in the expression (5w+3) the value of w is: w = -3/5.

Here, we have,

given that,

the expression is: (5w+3)

now, we have to find the value of w

so, we get,

we can find the value of w by making it equal to 0:

5w+3 = 0

<- subtract 3 from both sides

5w = -3  

<- divide 5 from both sides

5w/5 = -3/5

so, we have,

w = -3/5 is the final answer.

Hence, The solution is: in the expression (5w+3) the value of w is: w = -3/5.
