Answer:

Two rays (or lines) that begin at the same point or share same endpoint. If the lines have endpoints, they're rays. If not, they're lines.

Y-INTERCEPT

[tex]y = 5x^2 - 16x + 10[/tex]

The y-intercept is where the equation/curve/parabola cosses the y-axis.

The y-axis is where x = 0. (The x-axis is where y = 0)

To find the y-intercept:

[tex]\text{y-axis} \rightarrow \text{x = 0} \rightarrow y = 5(0)^2 -16(0) + 10 = 10[/tex]

The y-intercept must be at (0, 10)

X-INTERCEPT (ROOTS/SOLUTIONS)

[tex]y = 5x^2 - 16x + 10\\\text{make it equal 0}\\y = 0\\\therefore 5x^2 - 16x + 10 = 0[/tex]

We need to use the quadratic formula

The quadratic formula helps us find what values of [tex]x[/tex] make the equation = 0

Quadratic formula: [tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

[tex]x=\frac{-(-16) + \sqrt{(-16)^2-4(5)(10)}}{2(5)}\\\\x = \frac{16 + \sqrt{256-200}}{10}\\x = \frac{16 + \sqrt{56}}{10}\\x = \frac{16 + 2\sqrt{14}}{10}\\x = \frac{8 + \sqrt{14}}{5}\\\\\\x=\frac{-(-16) - \sqrt{(-16)^2-4(5)(10)}}{2(5)}\\\text{doing the same thing...}\\\text{end up with...}\\x = \frac{8 - \sqrt{14}}{5}\\[/tex]

The x-intercepts are at:

[tex](\frac{8 + \sqrt{14}}{5}, 0)\\(\frac{8 - \sqrt{14}}{5}, 0)[/tex]

333 chocolate bars

the amount of chocolate each person get.

[tex] \frac{333}{22} [/tex]

[tex] = 15.1363636364[/tex]

[tex] = 15.14[/tex]

[tex] = \frac{15.14}{1} [/tex]

[tex] \frac{15.14}{1} \times \frac{100}{100} [/tex]

[tex] = \frac{1514}{100} [/tex]

[tex] \frac{1514 \div 2}{100 \div 2} [/tex]

[tex] = \frac{757}{50} [/tex]

[tex] = 15 \frac{7}{50} [/tex]

Answer:

[tex]15\frac{7}{50}[/tex]

Step-by-step explanation:

Given that:

22 people share 333 chocolate bars equally. Each chocolate bar is the same size.

To Find:

About how much chocolate does each person get?

Solve:

Since, it given us that 22 people share 333 chocolate bars equally and how much chocolate does each person gets. Therefore we have to divide the chocolate bars by the number of people.

       [tex]\underline{\emptyspace2\emptyspace2}\\80\\\underline{\emptyspace6\emptyspace6}\\140\\\underline{\emptyspace13\emptyspace2}\\8[/tex]

Rounding to nearest tenth: 15.14

Now put 15.14 over 1

[tex]\frac{15.14}{1}[/tex]

Multiply both by 100

[tex]\frac{15.14}{1}\times\frac{100}{100}[/tex]

[tex]=\frac{1514}{100}[/tex]

[tex]=\frac{1514\div2}{100\div2}[/tex]

[tex]=\frac{757}{50}[/tex]

Turning into mixed number:

[tex]15\frac{7}{50}[/tex]

Thus, each person get about [tex]15\frac{7}{50}[/tex] chocolate

Answer:

4, -4, 10

Step-by-step explanation:

on these types of questions you can take each seperate parenthesis and equate it to 0

for example:

x^2 - 16 = 0

hence,

x^2 = 16

x = 4 or -4

second parenthesis:

10 - x = 0

x = 10

make sure to ask if you need any further guidance :)

Answer:

  (A)  7/(m+4)

Step-by-step explanation:

When fractions have a common denominator, you add them by adding their numerators and using that sum with the common denominator.

Here, you may be able to cancel a common factor from numerator and denominator to simplify the expression further.

  [tex]\dfrac{4m-17}{m^2-16}+\dfrac{3m-11}{m^2-16}=\dfrac{4m-17+3m-11}{m^2-16}=\dfrac{7m-28}{m^2-16}\\\\=\dfrac{7(m-4)}{(m+4)(m-4)}=\boxed{\dfrac{7}{m+4}}[/tex]

Answer:

z=10

Step-by-step explanation:

We know that the ratio 7:21 is equal to the ratio of 10:3z.

Let's model that in proportions:

7               10

-       =        -

21             3z

Now that the equation is in proportional form, we can cross-multiply to find the value of z.

7 * 3z = 21 * 10 - Multiply both sides

21z = 210 - Divide both sides by 21

z=10

The answer is z=10.

Step-by-step explanation:

it needs 4×2 = 8 cubes asking the length, 5×2 = 10 cubes along the width, and 3 1/2 × 2 = 7 cubes along the height.

so, altogether

8×10×7 = 560 cubes

Let's solve ~

Assume the number to be x, and let's proceed as per the given information :

[tex]\qquad \tt \dashrightarrow \: \dfrac{20}{100} \times x = 6 [/tex]

[tex]\qquad \tt \dashrightarrow \: \dfrac{x}{5} = 6[/tex]

So, the correct choice is C

20% of a number= 6.

the unknown number.

let the unknown be x.

[tex]20\% \times x = 6[/tex]

[tex] \frac{20}{100} = 6[/tex]

[tex]x = 6 \times \frac{100}{20} [/tex]

[tex]x = 30[/tex]

Hi!

Your answer is the 1st one, 36 inches of ribbon.

The question states this is a square picture frame. That means that all the side lengths are the same.

We are given a side length of 6 inches.

In order to find the area of a square, we multiply the length and the width together.

In this problem, the sides of the picture frame measure 6 inches. Therefore:

[tex]6*6=36[/tex]

For a similar problem, see:

https://brainly.com/question/26494746

How much inches of ribbon she requires to cover the square frame.

There is a square picture frame. And we know Area of square= (side)²

[tex] \text{Area of Square picture frame = (side)²}[/tex]

[tex] = (6) {}^{2} \\ = 36 \: \: \text{inches of ribbon}[/tex]

The paragraph to show the comparision between two classes semester grades on the basis of the terms

is given below:

A box and whisker plot is defined as a graphical method of displaying variation in a set of data.

From the first figure, write all the values where dark point is drawn

53, 62, 80, 86, 89  

        The upper extreme is the highest value, which is 89.

        The upper quartile is 86 and the lower quartile is 62.

       = Highest - Lowest

       =89-53

       =36

From the second figure, write all the values where dark point is drawn

56, 62, 74, 89, 96

        The upper extreme is the highest value, which is 96.

       The upper quartile is 89 and the lower quartile is 62.

       = Highest - Lowest

       =96-62

       =34

Answer:

A.  How many vehicles do Boston residents have per household?

Step-by-step explanation:

A statistical question is that question, which is answered by collecting variable data. For example - “How old are the students in your neighborhood?”

So, here the question that is not statistical is How many vehicles do Boston residents have per household? As its answer can be 1 or 2 at maximum.

Whereas;

B.  How much money do Boston residents spend on transportation every day? This is statistical as you need to conduct survey for this to collect data.

C.  How many Boston residents use public transportation?  This also needs survey to collect data and data will be variable.

D.  How many times per month do Boston residents use public transportation?  This is also statistical as you have to gather data from many people.

E.  How long does it take for Boston residents to travel to work? This is also statistical as everyone will have a variable answer depending on the distance they travel.
