Write the quadratic equation whose roots are −6 and 2 , and whose leading coefficient is 5 . (use the letter x to represent the variable.)

Answers

Here let the quadratic equation be ax^2 + bx + c We know that a=5 from the question. Since the roots are 6 and 2, the quadratic equation would take the form of a product like (a1x-b1)(a2x-b2). However, let's assume that a2=1 and b2=6, Since a=5, a1=5, then 5x-b1=5(x-2). Solving this shows that b1=10 So, the equation is (5x-10)(x-6)

A color printer prints 24 pages in 7 minutes. how many pages does it print per minute?

Answers

Final answer:

The color printer prints approximately 3.43 pages per minute. This is calculated by dividing the total number of pages (24) by the total printing time in minutes (7).

Explanation:

To calculate the number of pages a color printer prints per minute, we use the information provided that it prints 24 pages in 7 minutes. The calculation is a simple division problem:

Determine the rate by dividing the total number of pages by the total number of minutes.Pages per minute = Total pages printed ÷ Total minutesPages per minute = 24 pages ÷ 7 minutesCalculate the quotient to find the page rate.Pages per minute ≈ 3.43 pages per minute

Therefore, the printer prints approximately 3.43 pages per minute.

C. 0.16 (there is a line above 16)

D. 6

Answers

always remeber that the fraction bar is just a divison sign. with that being said, you are going to divide the numerator=1 by the denominator=6. this will then give the decimal form 1.6666666. Because it continues repeating it will be Answer B

i hope this helps:)

The equivalent decimal for 1/6 which represents the fraction preferred by Ramon's friend is: B. [tex]\mathbf{0.1\overline{6}}[/tex]

Note the following about recurring decimal:

Recurring decimals are decimal numbers having one or more digits that repeat forever.The digit or digits that repeat forever in a decimal number can be denoted by drawing a line over the repeating digits.

Thus:

The decimal equivalent of 1/6 = 0.16666..

6 is a repeating digits in the decimal number.

A line would be drawn above only 6 as:

[tex]\mathbf{0.1\overline{6}}[/tex]

In summary, the equivalent decimal for 1/6 which represents the fraction preferred by Ramon's friend is: B. [tex]\mathbf{0.1\overline{6}}[/tex]

Tony misplaced 777 stamps from his collection. He knows that each stamp of his is worth \$0.15$0.15dollar sign, 0, point, 15 and that the total value of them is now only \$5.55$5.55dollar sign, 5, point, 55.

Answers

There is no question being asked. If the answer needed is how many stamps does he have left take the total value and divide by the worth of each stamp. 5.55/0.15 = 37

Write an equation to represent the value of his stamp collection in terms of the number of stamps, s, that he had originally, and find the value of s.

Tony misplaced 7 stamps

Each stamp worth = $0.15

Total value of stamp now = $5.55

Let the number of stamps be 's'

Number of stamps now = s - 7 (misplaced 7 stamps)

price (number of stamps now ) = 0.55

0.15 (s - 7) = 5.55

Divide by 0.15 on both sides

s - 7 = 37

Add 7 on both sides

s = 44

Total number of stamps originally he had = 44 stamps

an angle is double its complement. find the angle and the complement

Answers

Complement means the other angle that will sum up to 90°

So:

x + 2x = 90°
3x = 90
x = 30°

So, it is 30° and 30 * 2°, or 60°

Answer:

60⁰

Step-by-step explanation:

Angke = x

Complement = 90 - x

Given:

x = 2 (90 - x)

x = 180 - 2x

3x = 180

x = 60⁰

Complement = 30⁰

What are the coordinates of the endpoints of the midsegment for △RST that is parallel TS¯¯¯¯¯ ?

Answers

So here all you have to do is use the midpoint formula: [tex] \frac{x+x}{2} , \frac{y+y}{2} [/tex] and plug-in RS points [tex] \frac{0+8}{2}, \frac{6+0}{2} [/tex]and RT points [tex] \frac{0+2}{2}, \frac{6+0}{2} [/tex]and you will get (1,3) and (4,3).

Answer:

The end points of midsegement for triangle RST are (1,3) and(4,3) which is parallel to TS.

Step-by-step explanation:

We are given that a figure of triangle RTS in which the coordinates of R(0,6) , T(2,0) and S(8,0).

We have to find the end points of midsegment for triangle RST that is parallel TS

Let AB is midsegment where A is the mid point of segment RT and B is the midpoint of segment RS of triangle RST which is parallel to the segment TS.

To find the coordinates of end point of midsegment AB using midpoint formula

Midpoint formula :[tex]x=\frac{x_1+x_2}{2}, y=\frac{y_1+y_2}{2}[/tex]

The coordinate of A

[tex]x=\frac{0+2}{2}[/tex], [tex]y=\frac{0+6}{2}[/tex]

[tex]x_1=0,x_2=2,y_1=6,y_2=0[/tex]

[tex]x=1,y=3[/tex]

The coordinates of A is (1,3).

The coordinates of mid point B

[tex]x=\frac{0+8}{2},y=\frac{0+6}{2}[/tex]

[tex]x_1=0,y_1=6,x_2=8,y_2=0[/tex]

[tex]x=4,y=3[/tex]

The coordinates of midpoint B is (4,3).

Therefore, the end points of midsegement for triangle RST are (1,3) and(4,3) which is parallel.

What is Linear Equation?

A linear equation is an algebraic equation of the form y = m x + b involving only a constant and a first-order linear term, where m is the slope and b is the y-intercept.

Given data ,

Let the two numbers be x and y , where the smaller number is x and larger number is y

Larger is 2 more than four times the smaller is expressed as

y = 2 + 4 x , be equation 1

The sum of two numbers is expressed as

x + y = 67 , be equation 2

Now we have two equations with two unknown variables

To find x and y , we substitute the value of y in equation 1

y = 67 - x

Therefore ,

67 - x = 2 + 4 x

5 x = 65

Dividing by 5 on both sides , we get

x = 13

Substituting the value of x in equation 2 , we get

y = 67 - 13

y = 54

Hence , the numbers are 13 and 54

You are adding up the quarters and dimes from your piggy bank so you can buy a new book. you have a total of 50 coins that add up to $9.80. how many quarters and how many dimes do you have?

Answers

Let [tex]Q[/tex] be the number of quarters you have, and [tex]D[/tex] be the number of dimes you have. With the information provided above, you have the following equation:

[tex]Q + D = 50[/tex]

Next, you know the value of a quarter is 0.25, and the value of a dime is 0.10, so you can set up the next equation:

[tex]0.25Q + 0.10D = 9.80[/tex]

Substituting the first equation into the second leads to the following:

[tex]0.25(50 - D) + 0.10D = 9.80[/tex]

Solving for [tex]D[/tex] will give you the number of dimes you have, and then you can easily figure out how many quarters you have as well.

How do you draw a skew line?

Answers

In three-dimensional geometry, skew lines are two lines that do not intersect and are not parallel. A simple example of a pair of skew lines is the pair of lines through opposite edges of a regular tetrahedron. Two lines that both lie in the same plane must either cross each other or be parallel, so skew lines can exist only in three or more dimensions. Two lines are skew if and only if they are not coplanar. Hope this helps!! :)

C. Y-intercept of (0, 1), starts up on the left, gets closer to y = −3 on the right
D. Y-intercept of (0, 1), starts down on the left, gets closer to y = −3 on the right

Answers

Answer: The correct option is B.

Explanation:

The given function is,

[tex]f(x)=4(\frac{1}{2})^{(x+1)} -3[/tex]

Put x=0 to find the y-intercept.

[tex]f(x)=4(\frac{1}{2})^{(0+1)} -3[/tex]

[tex]f(x)=4(\frac{1}{2}) -3[/tex]

[tex]f(x)=2-3[/tex]

[tex]f(x)=-1[/tex]

At x=0 the value of f(x) is -1, therefore the y- intercept is (0,-1).

Since it is an exponential function in the form of,

[tex]g(x)=ma^x+n[/tex]

Where, 0<a<1, so,

[tex]f(x)\rightarrow \infty\text{ as }x\rightarrow -\infty[/tex]

[tex]f(x)\rightarrow -3\text{ as }x\rightarrow \infty[/tex]

Therefore the starts up on the left, gets closer to y = −3 on the right. So the option B is correct.
