The base of an open rectangular box is of length (2x + 5) cm and width x cm.
The area of this base is 58 cm
The height of the open box is (x - 2) cm.
a) Show that 2x + 5x -58 = 0
) Solve the equation 2x + 5x -58 = 0, giving your answers correct
to 2 decimal places
D) Hence calculate the volume of the box, stating the units of your answer.

Answers

Answer:

a) x = 8.29 cm

D) V = 1125.27 cm³

Step-by-step explanation:

a) We can solve the equation as follows:

[tex] 2x + 5x - 58 = 0 [/tex]

[tex] 2x + 5x = 58 [/tex]

[tex] x = \frac{58}{7} = 8.29 [/tex]

D) The volume of the box is given by:

[tex] V = l*w*h [/tex]

Where:

l: is the length

w: is the width

h: is the height

The length of the rectangular box is:

[tex] l = (2x + 5) cm = (2*8.29 + 5) cm = 21.58 cm [/tex]

The width is x = 8.29 cm.

And the height is:

[tex] h = (x - 2) cm = (8.29 - 2) cm = 6.29 cm [/tex]

Hence, the volume is:

[tex] V = l*w*h = (21.58*8.29*6.29) cm^{3} = 1125.27 cm^{3} [/tex]

Answers

Given:

The equation of a line is:

[tex]y=-\dfrac{5}{7}x+2[/tex]

A line passes through the point (-5,-3) and perpendicular to the given line.

To find:

The equation of the line.

Solution:

Slope intercept form of a line is:

[tex]y=mx+b[/tex]                 ...(i)

Where, m is the slope and b is the y-intercept.

We have,

[tex]y=-\dfrac{5}{7}x+2[/tex]          ...(ii)

On comparing (i) and (ii), we get

[tex]m=-\dfrac{5}{7}[/tex]

We know that the product of slopes of two perpendicular lines is always -1.

[tex]m_1\times m_2=-1[/tex]

[tex]-\dfrac{5}{7}\times m_2=-1[/tex]

[tex]m_2=\dfrac{7}{5}[/tex]

Slope of the required line is [tex]\dfrac{7}{5}[/tex] and it passes through the point (-5,-3). So, the equation of the line is:

[tex]y-y_1=m_2(x-x_1)[/tex]

[tex]y-(-3)=\dfrac{7}{5}(x-(-5))[/tex]

[tex]y+3=\dfrac{7}{5}(x+5)[/tex]

Using distributive property, we get

[tex]y+3=\dfrac{7}{5}(x)+\dfrac{7}{5}(5)[/tex]

[tex]y+3=\dfrac{7}{5}x+7[/tex]

[tex]y=\dfrac{7}{5}x+7-3[/tex]

[tex]y=\dfrac{7}{5}x+4[/tex]

Therefore, the equation of the line is [tex]y=\dfrac{7}{5}x+4[/tex]. Hence, option A is correct.

Ifthe fish commission states that the mean length of all fish in spring run is mean =15cm,withthe standard deviation of variance=4cm,what will be the probability that a fish is caught in spring run :between 15cm&19cm?

Answers

Answer:

Step-by-step explanation:

z(lower) = (15-15)/4 = 0

z(upper) = (19-15)/4= 1

z  at  0 = .5

z at  1 = 0.841344746

(look these up in a Z table)

probability "between" = 0.841344746 - .5 = 0.3841344746

0.384 is the probability that a fish is caught in spring run between 15cm and 19cm

What is Statistics?

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

Given that  fish commission states that the mean length of all fish in spring run is mean =15cm

the standard deviation of variance=4cm,

We need to find  the probability that a fish is caught in spring run :between 15cm and 19cm

The z score formula is z=x-µ/σ

z(lower) = (15-15)/4 = 0

z(upper) = (19-15)/4= 1

From the table of z values we get

z  at  0 is 0.5

z at  1 is 0.841344746

probability between 0.841344746 -0 .5 is 0.3841344746

Hence, 0.384 is the probability that a fish is caught in spring run between 15cm and 19cm

C) The axis of symmetry is x = −1.5 and the vertex is (−1.5, 8.25).
D) The axis of symmetry is x = 0 and the vertex is (0, 6).

Answers

Answer:

C) The axis of symmetry is x = −1.5 and the vertex is (−1.5, 8.25).

Step-by-step explanation:

The axis of symmetry is x = − b/2a

= -(-3) / 2(-1)

= -1.5

the vertex => x = -1.5

y= -(-1.5)²-3(-1.5)+6 =

He average price of a home in a neighborhood of mostly leased properties is $259,000. The average monthly rent is $2,500. One home in the neighborhood is leased for $2,800. Using a GRM, what is the value of that home?

Answers

Answer:

$290,080

Step-by-step explanation:

Given:

Average price = 259,000

Average monthly rent = 2500

Monthly rent of home = $2800

Gross Rent Multiplier = price per monthly rent

GRM = Price / monthly rent

The GRM = 259000 ÷ 2500

= $103.60

The price = GRM * Monthly rent

Price = $103.60 * $2800

Price = $290,080

which are the slope and the y-intercept linear function that is represented by the graph?

Answers

Answer:

See explanation

Step-by-step explanation:

The question is incomplete, as the graph is not given.

The general step to calculate slope and y intercept is as follows;

Assume any two points on the graph are:

[tex](x_1,y_1) = (5,1)[/tex]

[tex](x_2,y_2) = (1,4)[/tex]

The slope (m) is:

[tex]m = \frac{y_2 -y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{4 -1}{1-5}[/tex]

[tex]m = \frac{3}{-4}[/tex]

[tex]m = -\frac{3}{4}[/tex]

The equation of the graph is:

[tex]y = m(x - x_1) + y_1[/tex]

This gives:

[tex]y = -\frac{3}{4}(x - 5) + 1[/tex]

[tex]y = -\frac{3}{4}x +\frac{15}{4} + 1[/tex]

[tex]y = -\frac{3}{4}x +\frac{15+4}{4}[/tex]

[tex]y = -\frac{3}{4}x +\frac{19}{4}[/tex]

To calculate the y intercept; set [tex]x = 0[/tex]

[tex]y = -\frac{3}{4}*0 +\frac{19}{4}[/tex]

[tex]y = \frac{19}{4}[/tex] ---- y intercept

Miguel made $286 for 13 hours of work.
At the same rate, how much would he make for 7 hours of work?

Answers

Answer:

Step-by-step explanation:

The key here is to find out how much he makes per hour. We can find that out using the info given.

286 = 13x so

x = 22 dollars per hour. For 7 hours of work then,

7(22) = $154

The person above is absolutely right and I agree with it! You could also find the unit rate this way:
Find the unit rate of dollars per hour:
286 ÷ 13 = 22

The region D represents the solution of the given system of inequalities.

What is the system of linear inequalities?

A system of linear inequalities is a collection of linear inequalities in the same variables.

How to shade the graph of inequalities?Rearrange the equations so "y" is on the left and everything else on the right. Plot the "y≤ ,y≥ ,y> or  y< " line.Shade above the line for a " greater then" and below for the "less than".

According to the given equation.

We have system of inequalities.

[tex]y < \frac{-1}{2}x[/tex]

and [tex]y \geq 2x + 3[/tex]

Also, the graph of the inequalities.

Since, y is less than [tex]-\frac{1}{2} x[/tex] shade  below the line.

And, for the second inequality.

y is greater than and equal to 2x + 3 therefore, shade the above the line.

So, the common region D we get after the shading.

Hence, region D represents the solution of the given system of inequalities.

La empresa tiene unos gastos fijos mensuales de local y personal de S/.9000, y además, fabricar cada unidad protector facial cuesta S/. 3. ¿Cuántas unidades ha de vender mensualmente si no quiere tener pérdidas?

Answers

Answer:

The number of units sell is 2.

Step-by-step explanation:

selling cost of one unit = $ 0.9

Monthly expense = $ 0.9

Manufacturing cost = $ 0.3

Let the number of unit sell is x.

So,

0.9 x = 0.9 + 0.3 x

0.6 x = 0.9

x = 1.5

So, the number of units sell to get no loss is 2.

Answers

Answer:

Step-by-step explanation:

Use the standard form equation along with 3 of the coordinates from the table. I used (-1, 2.5), (0, 5), and (1, 8.5). Begin always with the coordinate where you have a 0:

[tex]5=a(0)^2+b(0)+c[/tex] and we get immediately that c = 5. We can use that value as move forward with the next coordinate pair.

[tex]8.5=a(1)^2+b(1)+5[/tex] and

8.5 = a + b + 5 and

3.5 = a + b Hold that thought while we come up with the second equation for this system.

[tex]2.5=a(-1)^2+b(-1)+5[/tex] and

2.5 = a - b + 5 and

-2.5 = a - b  Now solve this system using the method of eliination:

  a  +  b  =  3.5

+ a  -  b  = -2.5

so

2a = 1 and a = 1/2 Now we can plug that in and solve for b:

a + b = 3.5 becomes

1/2 + b = 3.5 so

b = 3 and the equation is

[tex]y=\frac{1}{2}x^2+3x+5[/tex]
