Which of the following is an extraneous solution of the square root of -3x-2=x+2

yarga [219]

Answer:

x=-6 is an extraneous solution

Step-by-step explanation:

we have

$\sqrt{-3x-2} =x+2$

squared both sides

$-3x-2=(x+2)^2$

$-3x-2=x^2+4x+4$

$x^2+7x+6=0$

solve the quadratic equation by graphing

The solution is x=-6 and x=-1

see the attached figure

<u><em>Verify each solution</em></u>

substitute the value of x in the original expression

For x=-6

$\sqrt{-3(-6)-2} =-6+2$

$\sqrt{16} =-4$

$4=-4$ ----> is not true

so

Is an extraneous solution

For x=-1

$\sqrt{-3(-1)-2} =-1+2$

$\sqrt{1} =1$

$1=1$ ----> is true

so

Is the solution

<h3>what is mensuration?</h3>

Mensuration is the branch of geometry that deals with measurement of volumes and areas of geometrical shapes.

Analysis:

1. volume of cylinder =π $r^{2}$ h. where r = 6/2 = 3 yard, h = 8 yard

= $\frac{22}{7}$ x $3^{2}$ x 8 = 226.29 cubic yard

2. volume of cone = $\frac{1}{3}$ x π $r^{2}$ h. where r = 2inches, h = 11

= $\frac{1}{3}$ x $2^{2}$ x $\frac{22}{7}$ x 11 = 46.1 cubic inches

3. volume of cylinder = π $r^{2}$ h. where r = 8, h = 12

= $\frac{22}{7}$ x $8^{2}$ x 12 = 2413.71 cubic inches

4. volume of cone = $\frac{1}{3}$ x π $r^{2}$ h. where r = 4, h = 14

= $\frac{1}{3}$ x $\frac{22}{7}$ x $4^{2}$ x 14 = 234.67 cubic millimeter

5. volume of cone = $\frac{1}{3}$ x π $r^{2}$ h. where r = 5, h = 13

= $\frac{1}{3}$ x $\frac{22}{7}$ x $5^{2}$ x 13 = 340.48 cubic yards

6. volume of cylinder = π $r^{2}$ h. where r = 3, h = 4

= $\frac{22}{7}$ x $3^{2}$ x 4 = 113.14 cubic feet

7. volume of cone = $\frac{1}{3}$ x π $r^{2}$ h. r = 6, h = 14

= $\frac{1}{3}$ x $\frac{22}{7}$ x $6^{2}$ x 14 = 528 cubic centimeter

8. volume of cylinder = π $r^{2}$ h. where r = 6, h = 8

= $\frac{22}{7}$ x $6^{2}$ x 8 = 905.14 cubic centimeter

9. volume of cylinder = π $r^{2}$ h. where r = 1.5, h = 4

= $\frac{22}{7}$ x $1.5^{2}$ x 4 = 56.57 cubic feet

In conclusion, the volume of cylinders and cones for the given dimensions are:

1. 226.29 cubic yard

2. 46.1 cubic inches

3. 2413.71 cubic inches

4. 234.67 cubic millimeter

5. 340.48 cubic yards

6. 113.14 cubic feet

7. 528 cubic centimeter

8. 905.14 cubic centimeter

9. 56.57 cubic feet

Using the following data state errors in the box and whisker plot 33,27,6,34,31,59,26,1,30

ratelena [41]

AnswerStep-by-step explanation:

To find out the errors made in the data plot, let's determine what the five-number summary of the data set that should be displayed by the box plot should be.

First, order the data set given:

1, 6, 26, 27, 30, 31, 33, 34, 59

The five-number summary are:

1. Min value = 1

2. Max value = 59

3. Median = 30

1, 6, 26, 27, (30),31, 33, 34, 59

4. Q1 = (26+6) ÷ 2 = 16

1, [6, 26], 27, (30), 31, 33, 34, 59

5. Q3 = (33+34) ÷ 2 = 33.5

1, 6, 26, 27, (30), 31, [33, 34], 59

The errors in the box and whisker plot are:

1. The min value was displayed as 0 instead of 1.

2. The first quartile (Q1) was displayed as 10 instead of 16

3. The third Quartile (Q3) was displayed as 35 instead of 33.5

4. The max value was displayed as 60 instead of 59.
