Answer:

Perpendicular

Step-by-step explanation:

What I would do first is to rearrange these equations into the equation of a line formula: [tex]y=mx+c[/tex]

To do so, we isolate y:

x - y = 4 -> -y = -x+4 -> (multiply both sides by -1) y=x-4

x+y=9 -> y=-x+9

We know that in the formula y=mx + c, m stands for gradient of a line (The degree of steepness of the line), and we know that if there is no number before x it means that it is 1 or -1 (depending on the sign before x).

so that on y=x-4 the gradient is 1 and on y=-x+9 the gradient is -1.

We now can check if its parallel, perpendicular or neither with these equations:

m1 · m2 = -1 for perpendicular,   m1 = m2  for parallel,(where m = gradient)

we plug the values of the two gradients into the first equation

(m1 · m2 = -1) and it fits: 1 x -1 = -1

If we plug the same values into the second equation (m1 = m2), we can check that 1 ≠ -1

In conclusion, we can check that these lines are perpendicular to each other.

Answer:

Step-by-step explanation:

If we want to find the slope, the most easiest way to find the slope is to use 'Rise/Run'. Two points are given, lets use those points and find the slope.

=> We see that the rise is 2. So 2 will be our numerator,

=> We can also see that the run is 3. So 3 will be our denominator.

What do we get?

We get 2/3 as our slope. Therefore, B is our answer. Hoped I helped.

Answer:

To find the rate of change you use the formula, Y2-Y1/X2-X1.

Function A:

You can substitute in any two points. The points I will use are (0,0) and (1,1).

1-0/1-0

1/1

1

The rate of change for Function A is 1.

Function B:

The points I will use are (2,1) and (4,2).

2-1/4-2

1/2

The rate of change for Function B is 1/2.

Since 1 is larger than 1/2, Function A has a larger rate of change. The value is 1.

Answer:

  d/3

Step-by-step explanation:

For k = 8c, the concentration is ...

  S = c/x^2 + 8c/(d -x)^2

The minimum of the function will be found where its derivative is zero. The derivative with respect to x is ...

  S' = -2c/x^3 +(-2)(8c)(-x)/(d -x)^3

We are interested in the value of x that makes this zero.

  0 = -2c/x^3 +16c/(d -x)^3 . . . . . simplify slightly, set S'=0

  0 = (-2(d -x)^3 +16x^3)/(x(d -x))^3 . . . . . combine terms, divide by c

  0 = d^3 -3d^2x +3dx^2 -x^3 -8x^3 . . . . multiply by (x(d-x))^3/(-2)

  9x^3 -3dx^2 +3d^2x -d^3 = 0 . . . . . simplified cubic

Factoring by grouping, we have ...

  (9x^3 -3dx^2) +(3d^2x -d^3) = 0

  3x^2(3x -d) +d^2(3x -d) = 0

  (3x^2 +d^2)(3x -d) = 0

The solution will be found where the second of these factors is zero:

  3x -d = 0

  x = d/3

The concentration of the deposit is a minimum at x = d/3 miles.

The graph shows the minimum is x = 1/3 when d = 1.

Answer:

$1.10

Step-by-step explanation:

5.50 divided by 5, take a way the decimal in order to divide. 550/5=110

55 divided by 5 is 11 just add a zero

Part A

p = 0.32 = probability of someone voting by internet

n = 13 = sample size

x = 10 = number of people who voted by internet

Apply the binomial probability formula.

[tex]P(x) = (_n C _x)*(p)^{x}*(1-p)^{n-x}\\\\P(10) = (_{13} C _{10})*(0.32)^{10}*(1-0.32)^{13-10}\\\\P(10) = (286)*(0.32)^{10}*(0.68)^{3}\\\\P(10) \approx 0.0010124942242\\\\P(10) \approx \textbf{0.00101}\\\\[/tex]

Note: the [tex]_n C_x[/tex] refers to the combination formula.

=============================================================

Part B

We could apply the binomial theorem for the following values of x: {10,11,12,13}. Then would add up the results.

However, such a task is fairly tedious and it's more efficient to use computer software (or a graphing calculator). Also, there's the element of limited time that you'll need to consider. I showed the steps for part A above because your teacher may have wanted you to list them. Usually it's better to rely on software for that task as well. At the very least, it's useful to have software to check your answer.

Whichever method you use, you should find the following:

The last value isn't exactly 0, but it's so small that it's effectively zero. This is because we only have 5 decimal places to work with.

Add up those four values to get:

[tex]P(x \ge 10) = P(10)+P(11)+P(12)+P(13)\\\\P(x \ge 10) \approx 0.00101+0.00013+0.00001+0\\\\P(x \ge 10) \approx 0.00115\\\\[/tex]

A faster shortcut is to use your calculator's binomCDF function.

This result of 0.00115 is fairly small. The usual distinction we make between whether a probability is small or not is to set up some kind of threshold. This threshold is known as the significance level. By default, it's set to 0.05 unless your teacher specifies otherwise. Another common significance level is 0.01, but it's usually mentioned.

Since 0.00115 is smaller than 0.05, and even 0.01, we consider the probability of getting 10 or more internet voters to be a significant event. It's fairly unusual to get 10 or more people voting by internet in this sample of n = 13 people.

=============================================================

Part C

Like with part B, we could find the binomial probability values for x = {1,2,3,...,11,12,13}. We could add up the values like I did, or use the binomCDF function which is faster.

Another approach is to use the complement of the event "at least 1". If x is some number in the set {0,1,2,..,12,13}, then either [tex]x = 0[/tex] or [tex]x \ge 1[/tex]

From this, we can say

[tex]P(x=0) + P(x \ge 1) = 1\\\\P(x \ge 1) = 1-P(x=0)\\\\P(x \ge 1) \approx 1-0.00665\\\\P(x \ge 1) \approx 0.99335\\\\[/tex]

This then rounds to 0.993

Answer:

x^2 + 7x- 3/x - 3/x^2 -16

Step-by-step explanation:

Key:  ( ^ ) means exponent

= x^2 + 2x- 3/x -2x^2 + 5x- 3/x^2 -16

= x^2 - 2x^2 + 2x+5x - 3/x- 3/x^2 -16

= x^2 - 2x^2 = -x^2

=  -x^2 + 2x + 5x- 3/x- 3/x^2-16

As you see you add 2x and the 5x and got 7x

= Answer : x^2 + 7x- 3/x - 3/x^2 -16

Answer:

Using formula to calculate the circumference of wheel:

where

D is the distance bike travel

n is the number of times rotation

C is the circumference of the wheel

As per the statement:

Lin’s bike travels 100 meters when her wheels rotate 55 times.

here, n = 55 rotation and D = 100 meter.

then by definition:

meter

Therefore, the circumference of her wheel is, 1 9/11

Answer:

  (4, -7)

Step-by-step explanation:

Maybe you want the solution to this system of equations.

About the easiest way to obtain it is to use a graphing calculator.

   (x, y) = (4, -7)

_____

Additional comment

Since one of the equations gives an expression for y, it is a simple matter to substitute that for y in the other equation.

  4x +(-2x +1) = 9

  2x = 8 . . . . . . . . . . subtract 1 and simplify

  x = 4

  y = -2(4) +1 = -7 . . . use the first equation to find y

Answer:

3.5 ft

Step-by-step explanation:

[tex]1 \frac{3}{4} = \frac{7}{4} [/tex]

7/4 inch = ? feet

[tex] \frac{ \frac{1}{2} }{ \frac{7}{4} } = \frac{1}{x} \\ \\ \frac{4}{14} = \frac{1}{x} \\ x = \frac{7}{2} [/tex]

3.5 ft

Answer:

3.5 ft.

Step-by-step explanation:

The question describes a bookshelf with width given in inches and we have to find the actual width in feet.

That makes it

The bookshelf drawn by Sarita is

[tex]1 \frac{3}{4} [/tex]

inches wide.

Any fraction with it's quotient greater than or equal to 1 can be expressed in the form of mixed fraction.

It combines a whole number and a fractional reminder. The whole number represents how many complete wholes you have.

So, to convert a mixed fraction to an improper fraction, following steps will be conducted:

STEP I

(multiply the whole number by the denominator)

In this case,

[tex] 1\frac{3}{4} [/tex]

= 4 × 1

= 4

STEP II

(add the product to the numerator)

= 3 + 4

= 7

STEP III

(place the numerator obtained in Step 3 over the denominator)

Which gives us the fraction:

[tex] \boxed{ \frac{7}{4} }[/tex]

So, the width of the bookshelf is 7/ 4 in.

[tex] \mathsf{ \frac{1}{2} \: inches \: represent = 1 \: feet }[/tex]

[tex] \mathsf{ 1 \: inch \:will\: represent = 1 \times \: \frac{2}{1} feet }[/tex]

[tex] \mathsf{ \frac{7}{4} \: inches \:will\: represent = 2 \times \: \frac{7}{4} feet }[/tex]

[tex] \implies \mathsf{ \underline{\frac{7}{2} \: ft. }}[/tex]

[tex] \mathsf{or}[/tex]

[tex] \implies \: \mathsf{ \underline{3.5 \: ft.}}[/tex]

That makes it Option: D) 3.5 ft.

4x2−12x+9=0

Step-by-step explanation:

The equation, 2x2+x+3=0, does not have a solution

The equation, x2+5x−3=0, equals -5/2+1/2√37 and -5/2+-1/2√37

The equation, x2−5x+4=0, equal 1 and 4

The equation, 4x2−12x+9=0, equals only 3/2
