A rectangle has an area of 54 square inches and a length of 6 in what is the width in inches of the rectangle?​

Answers

[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]

Actually Welcome to the Concept of the Areas and Volumes.

We know that, Area of a Rectangle = length * Width.

Since,here Length = 6 inch and Area = 54 square inches,

==> Width = Area / length

==> Width = 54/6

=> Width = 9 inches.

Hence the width of the rectangle is 9 inches.

Two families went to Rollercoaster World. The Garcia family paid $170 for 3 children and 2 adults. The McGruder family paid $360 for 4 children and 6 adults.

If x is the price of a child’s ticket in dollars and y is the price of an adult’s ticket in dollars, write a system of equations the models this situation.

Answers

Answer:

3x +2y  =170  ---equation 1

4x +6y  =360 ---equation 2

Price of child 's ticket =$30

price of an adult’s ticket  =$40

Step-by-step explanation:

Let x represent  the price of a child’s ticket in dollars

and y represent  the price of an adult’s ticket in dollars

Such that

3 children and 2 adults for the cost of $170 be represented as

3x +2y  =170  ---equation 1

4 children and 6 adults for the cost of $360 be represented as

4x +6y  =360 ---equation 2

3x +2y  =170  ---equation 1

4x +6y  =360 ---equation 2

bY Elimination method  Multiplying equation 1 by 4 and equation 2 by 3

12x+8y =680---equation 3

12x +18y =1080---equation 4

Subtracting equation 3 from 4

10 y=400

y =400/10

y=40

Puting the value of y=40 in equation 1 to foind x

3x +2y  =170  

3x+2 x 40=  170

3x+80 =170

3x=170-80

3x=90

x=90/3=30

Price of child 's ticket =$30

price of an adult’s ticket  =$40

Find an equation of the tangent line to the curve at the given point. y = x3 − 3x + 2, (3, 20)

Answers

Answer:

[tex]y - 20 = 24(x - 3)[/tex]

Step-by-step explanation:

Equation of a line:

The equation of a line, in point-slope form, has the following format:

[tex]y - y_0 = m(x - x_0)[/tex]

In which the point is [tex](x_0,y_0)[/tex] and the slope is m.

(3, 20)

This means that [tex]x_0 = 3, y_0 = 20[/tex]. So

[tex]y - y_0 = m(x - x_0)[/tex]

[tex]y - 20 = m(x - 3)[/tex]

Slope:

The slope is the derivative of the function at the point:

The function is:

[tex]y = x^3 - 3x + 2[/tex]

The derivative is:

[tex]y^{\prime}(x) = 3x^2 - 3[/tex]

At the point, we have that [tex]x = 3[/tex]. So

[tex]m = y^{\prime}(3) = 3*3^2 - 3 = 27 - 3 = 24[/tex]

So the equation to the tangent line to the curve a the point is:

[tex]y - 20 = 24(x - 3)[/tex]

Answers

Answer: #5 = -3    #6 =  0, there is no x

Step-by-step explanation:  #5 -   first you have to turn it into slope-intercept form. So, 3y+12=-9x will become y= -3x -4 because you divide all sides by 3 and you transpose 12 so it becomes negative... then you will pick out you slope which is the number in front of x so slope = -3

#6 - the slope is zero because there is no x in that equation.

5. The slope is -3 and the y intercept is (0,-4)

Find the sample size required to achieve the given margin of error with SD = 51.02 and z - score = 1.96. Round your answer to the nearest whole number. margin of error = 2

Answers

Answer:

The sample size required is 2500.

Step-by-step explanation:

z-score:

In function of the margin of error M, the z-score is given by:

[tex]Z = \frac{M}{\frac{\sigma}{\sqrt{n}}} = \frac{M\sqrt{n}}{\sigma}[/tex]

In this question, we have that:

[tex]\sigma = 51.02, M = 2, Z = 1.96[/tex]

So

[tex]Z = \frac{M\sqrt{n}}{\sigma}[/tex]

[tex]1.96 = \frac{2\sqrt{n}}{51.02}[/tex]

[tex]2\sqrt{n} = 51.02*1.96[/tex]

[tex]\sqrt{n} = \frac{51.02*1.96}{2}[/tex]

[tex](\sqrt{n})^2 = (\frac{51.02*1.96}{2})^2[/tex]

[tex]n = 2500[/tex]

The sample size required is 2500.
