Answer:

C, (6, ∞)

Step-by-step explanation:

The x intercept is 6, and it continues downward for infinity. :) I had this question on my assignment today and it was right!

Interval of the domain for which function is negative is equals to ( 6, ∞).

" Function is defined as relation between two variable is such that for all the inputs there is exactly one output."

Standard equation of the line

y = mx + b

b = y-intercept

m = slope

According to the question,

For the given line in graph,

y- intercept = 4

x- intercept = 6

Therefore ,

For the function y = mx + b  we have,

b = 4

y = mx + 4

Substitute the value of x- intercept in the function y = mx +4 we get,

when x = 6 , y= 0

[tex]0 = m(6) + 4\\\\\implies m= \frac{-4}{6}\\ \\\implies m= \frac{-2}{3}[/tex]

Function [tex]y = \frac{-2}{3}x+ 4[/tex]

Interval of the domain is function is  negative.

[tex]y < 0 \\\\\implies \frac{-2}{3}x+ 4 < 0\\\\\implies -2x + 12 < 0\\\\\implies -2x < -12\\\\\implies 2x > 12\\\\\implies x > 6[/tex]

Interval of the domain is function is  negative is ( 6, ∞).

Hence, Option (C) is the correct answer.

Answer:

Her return is  [tex]R = 0.10[/tex]

Step-by-step explanation:

From the question we are told that

   The number of shares purchased is [tex]n = 100 \ shares[/tex]

    The  cost price  of each share is  [tex]x = \$ 20[/tex]

    The limit order is    [tex]y = \$ 33[/tex]

    The first  market price for each share is  [tex]k = \$ 23[/tex]

    The second   market price for each share is [tex]u = \$ 26[/tex]

     The  third market price for each share is  [tex]w = \$ 22[/tex]

Generally the  limit order would  not be  executed given that it is higher than the market opening and  closing price.

  Considering Rebecca's initial investment of $ 20 per share, her return is mathematically evaluated as

         [tex]R = \frac{w + d - x}{x}[/tex]

Here d stands for the dividend but since we are told that the stock did not pay any dividend

        [tex]R = \frac{22 + 0 - 20}{20}[/tex]

         [tex]R = 0.10[/tex]

Answer:

1) [tex]a=\dfrac{F}{m}[/tex]

2) [tex]m=\dfrac{p}{v}[/tex]

Step-by-step explanation:

1) The given equation is

[tex]F=ma[/tex]

We need to solve this for a.

In the given triangle place single variable i.e., F, on the top and variables in the product in the bottom (order of m and a does not matter) as shown in the below figure.

Using the triangle and the operations (× and ÷), we get

[tex]F=ma[/tex]

[tex]a=\dfrac{F}{m}[/tex]

[tex]m=\dfrac{F}{a}[/tex]

Therefore, the required answer is [tex]a=\dfrac{F}{m}[/tex].

2) The given equation is

[tex]p=mv[/tex]

We need to solve this for m.

In the given triangle place single variable i.e., p, on the top and variables in the product in the bottom (order of m and v does not matter) as shown in the below figure.

Using the triangle and the operations (× and ÷), we get

[tex]p=mv[/tex]

[tex]m=\dfrac{p}{v}[/tex]

[tex]v=\dfrac{p}{m}[/tex]

Answer:y=0 So its A

Step-by-step explanation:3(-y+7)=3(y+5)+6

We move all terms to the left:

3(-y+7)-(3(y+5)+6)=0

We add all the numbers together, and all the variables

3(-1y+7)-(3(y+5)+6)=0

We multiply parentheses

-3y-(3(y+5)+6)+21=0

We calculate terms in parentheses: -(3(y+5)+6), so:

3(y+5)+6

We multiply parentheses

3y+15+6

We add all the numbers together, and all the variables

3y+21

Back to the equation:

-(3y+21)

We get rid of parentheses

-3y-3y-21+21=0

We add all the numbers together, and all the variables

-6y=0

y=0/-6

Answer:

66

Step-by-step explanation:

To find the range, find the difference between the smallest and largest values

The largest value is 193 and the smallest is 127

193 - 127

= 66

The range of Roger's score after he bowled 7 games last weekend is 66

Given scores:

155, 165, 138, 172, 127, 193 , 142

The highest score is 193

Lowest score is 127

Range = Highest score - Lowest score

= 193 - 127

= 66

Therefore, the range of Roger's score after he bowled 7 games last weekend is 66

Here the length of ladder is equal to hypotenuse of ∆ so formed.

Now in a right angled ∆ ,

=> (hypotenuse)² = (pependicular)²+(base)².

=> h ² = (12m)²+(5m)²

Answer:

Step-by-step explanation:

7.05 p.m we can call it as 19.05

and 1.00 p.m means 13.00

so time  from 19.05 to 24.00 is = 24.00-19.05= 4.55 hr

from 24.00 to 13.00 is = 13.00 hr

so total hr is 4.55 + 13.00= 17.55 hr

Answer:

[tex]A(L) = 4L - L^2[/tex]

Step-by-step explanation:

Given

Perimeter = 8m

Required

Determine its area as a function of length

Represent Length and Width with L and W, respectively;

Perimeter (P) is calculated as thus;

[tex]P = 2(L + W)[/tex]

Substitute 8 for P

[tex]8 = 2(L + W)[/tex]

Divide both sides by 2

[tex]4 = L + W[/tex]

Make W the subject of formula

[tex]W = 4 - L[/tex]

Area (A) of a rectangle is calculated as thus:

[tex]A = L * W[/tex]

Substitute 4 - L for W

[tex]A = L * (4 - L)[/tex]

Open bracket

[tex]A = 4L - L^2[/tex]

Represent as a function

[tex]A(L) = 4L - L^2[/tex]

Area of rectangle in terms of length L is

[tex]A(L)= 4L-L^2[/tex]

Given :

A rectangle has perimeter 8 m. Express the area A of the rectangle as a function of the length, L, of one of its sides

We know that the perimeter of rectangle formula is

[tex]perimeter = 2(length)+2(width )[/tex]

perimeter is 8m

Let the length of rectangle is L

[tex]P=2L+2W\\8=2(L+W)\\4=L+W\\W=4-L[/tex]

so width is 4-L

Now we use area formula

Area of rectangle = length times width

[tex]A=L(W)\\A=L(4-L)\\A= 4L-L^2[/tex]

Area of rectangle in terms of length L is

[tex]A= 4L-L^2[/tex]

Answer:

0 => -⅘ => 1.5 => 3 => -4 => [tex]-\frac{11}{2} (-5.5)[/tex]

Step-by-step explanation:

The greater the absolute value of a slope, the steeper the slope. By absolute value, we mean the non-negative value of tthe .

To arrange the slope values, from the least steep to the steepest, ignore the negative sign in any of the slope values.

Thus, in the order from the least steep to the steepest, we have:

0 => -⅘ => 1.5 => 3 => -4 => [tex]-\frac{11}{2} (-5.5)[/tex]

The greater the absolute value of the slope, the greater the vertical movement. The greater the vertical movement, the steeper the slope.

A slope value of 0 connotes a horizontal line.

Answer:

We have a circular track that is 1 meter wide, which would mean that the diameter is equal to 1 meter.

First, we want to define this problem as a one dimensional problem. The position 0 is in the doorway, the bedroom is the positive axis, and the hallway is the negative side.

P(t) = R*cos(c*t) + R*sin(c*t).

Where R is the amplitude, in the case of the circular motion, R is equal to the radius.

If the diameter is 1m, the radius is 1m/2 = 0.5m

The equation now is:

P(t) = 0.5m*cos(c*t) + 0.5m*sin(c*t).

We also know that for t = 0s, the train is as far into the bedroom as it can, the maximum position is P = 0.5m

Then  we have:

P(0s) = 0.5m*1 + 0.5*0 = 0.5m

And we also know that the period is t = 2seconds.

The period for the sine and cosine functions is 2*pi, then:

c*2s = 2*pi

c =pi/s

The function now is:

P(t) = 0.5m*cos(t*pi/s) + 0.5m*sin(t*pi/s)

When this function is positive, this means that the train is inside her bedroom, when the function is negative, the train is outside the bedroom, when P(t) = 0, the train is in the doorway.

Step-by-step explanation:

GIVEN DATA :

Test statistic = 4.99

significance level = 1% = 0.01

k ( number of groups ) = 3

will we use the chi-squared test to determine the degree of freedom

which is : k-1 = 3 - 1 = 2

looking at the chi-square table to determine the critical value of the test

at significance level = 0.01 and degree of freedom = 2 the critical value = 9.21

Comparing the test value ( 4.99 ) and the critical value ( 9.21 ) it can seen  that the test value < critical value  which is a condition for not rejecting null hypothesis of the test.

therefore we won't reject the null hypothesis

Answer:

f(5) = 22

Step-by-step explanation:

When we want to solve for f(x) = 5x - 3 when x is 5, all we have to do is plug in 5 as x into the equation.

f(x) = 5x - 3

f(5) = 5(5) - 3

5 * 5 = 25

25 - 3 = 22

After you find the sums for each set, make a list, counting the number of ways a sum can occur.

You'll notice that for Set A, sums of 5, 6, 7, 8, and 9 all appear 4 times.  So they have equal probabilities.  In Set B, a sum of 7 appears 6 times.  Sums smaller or larger than 7 are less common.

When we look at the data, we see that were more sums of 7 than any other sum.  So this data was probably from Set B.
