Find the length of x please

Answer: x = -.63, -2.37

Step-by-step explanation:

x=−32±3–√2

x=−0.633975

x=−2.36603

Find the Solution for

2x2+6x+3=0

using the Quadratic Formula where

a = 2, b = 6, and c = 3

x=−b±b2−4ac/√2a

x=−6±62−4(2)(3)/√2(2)

x=−6±36−24/√4

x=−6±12−−√4

The discriminant b2−4ac>0

so, there are two real roots.

Simplify the Radical:

x=−6±23–√4

x=−64±23–√4

Simplify fractions and/or signs:

x=−32±3–√2

which becomes

x=−0.633975

x=−2.36603

The volume of the conical enclosure is approximately 871 ft³.

The density of the birds in the enclosure is number of birds / volume

The number of bird per cubic ft is 0.04822043628 birds per cubic foot

volume of a cone = 1 / 3 πr²h

where

Therefore,

v = 1 / 3 × 3.14 × 8² × 13

v = 1 / 3 × 3.14 × 64 × 13

v = 2612.48 / 3

v = 870.826666667

v = 870.83 ft³

The density of the birds in the enclosure is the mass of the birds divided by the volume of the enclosure.

The number of bird per cubic ft is as follows:

density = 42 / 871 = 0.04822043628 birds per cubic foot

Answer: 972π in³

Step-by-step explanation:

  We will use the proper formula to solve for the volume of the sphere.

-> The radius (r) is half the diameter. 18 in / 2 = 9 in

V = [tex]\frac{4}{3}[/tex]πr³

V = [tex]\frac{4}{3}[/tex]π(9)³

V = [tex]\frac{4}{3}[/tex] * (9)³ * π

V = 972π in³

   The volume is 972π in³

Answer:

Steps to factorize quadratic equation ax2 + bx + c = 0 using completeing the squares method are: Step 1: Divide both the sides of quadratic equation ax2 + bx + c = 0 by a. Now, the obtained equation is x2 + (b/a) x + c/a = 0. Step 2: Subtract c/a from both the sides of quadratic equation x2 + (b/a) x + c/a = 0.

Answer:

112 62 174

8 78 86

120 140 260

Step-by-step explanation:

You can solve this problem easily by looking at the total amounts compared to the information you already have. Once you do this, you can simply subtract them from each other to find the first two empty boxes, then you can just add across for the totals for the boxes on the right.

The complete two-way table looks like:-

.                                                        Identified As:

                                               Savers   Spenders   Total

                        Savers              112           62           174

Wants to be:    Spenders             8            78             86

                        Total                 120          140           260

A two-way table displays the frequencies or relative frequencies of two categorical variables. One category is represented by rows, while the other is represented by columns.

In the question, we are asked to complete the two-way table as per the given information.

In the first row, second column:

The box needs the data for the number of spenders who want to become savers.

In the provided information, we have been told that of the 140 people who identified themselves as spenders, 78 said they would continue being spenders, while the rest said they would like to be savers.

Thus, the number of spenders who want to be savers = 140 - 78 = 62.

Hence, entry is 62.

In the first row, third column:

The box needs the data for the number of people who now want to continue as savers, or become one.

This can be shown as the sum of the first two readings of the row.

Thus, the total number of people who now want to continue as savers, or become one = 112 + 62 = 174.

Hence, entry is 174.

In the second row, first column:

The box needs the data for the number of savers who want to become spenders.

In the provided information, we have been told that of the 120 people who identified themselves as savers, 112 said they would continue being savers, while the rest said they would like to be spenders..

Thus, the number of savers who want to be spenders = 120 - 112 = 8.

Hence, entry is 8.

In the second row, third column:

The box needs the data for the number of people who now want to continue as spenders, or become one.

This can be shown as the sum of the first two readings of the row.

Thus, the total number of people who now want to continue as spenders, or become one = 8 + 78 = 86.

Hence, entry is 86

Thus, the complete two-way table looks like:-

.                                                        Identified As:

                                               Savers   Spenders   Total

                        Savers              112           62           174

Wants to be:    Spenders             8            78             86

                        Total                 120          140           260

Answer:

Rafael will read 240 pages.

Step-by-step explanation:

Let's start by setting up the unknowns:

x = # of Rafael's pages

x/2 = # of Philippe's pages

(3/4)x = # of Denise's pages

Set these all equal to 540:

(x) + (x / 2) + (3/4(x)) = 540

Let's multiply both sides by 4 to make this easier.

4x + 2x + 3x = 2160

9x = 2160

x = 240

x was the # of Rafael's pages, so Rafael will read 240 pages. This means that Philippe will read 120 pages (one-half of Rafael), and Denise will read 180 pages (three-fourths of Rafael). Adding these all up will get you 540 pages, so it checks out.

Option C and D are correct but  is missing in the options

Option A and B are incorrect.

[tex]\pi =3.14[/tex] to solve the area of sphere when radius is given a constant value.

Answer:

See below

Step-by-step explanation:

Find the radius

  circumference = pi d

           16 pi        = pi d

      then d = 16      radius = 8    units

area of the TWO ends  = TWO * pi (8)^2 =128 pi   units^2

Find the height

  hypotenuse = 10     one leg = radius = 8

          10^2 = 8^2 + h^2

               h = 6 units

lateral area =   circumference * height

                    =   16 pi * 6 = 96 pi    units^2

total area is then   128 pi + 96 pi = 224 pi  units^2

The relative frequency of students who purchased popcorn in a movie at the local theater is 35.89%.

Relative frequency of a event is the measure of something happens relative to the total outcomes of that event.

The relative frequency can be given as,

[tex]f_r=\dfrac{f}{n}[/tex]

Here, (f) is the frequency of the number of times data occurred in an event and (n) is the total number of outcomes.

The relative frequency can also be defined as, it is the ratio of subgroup frequency to the total frequency of any event.

One weekend, 156 students went to see a movie at the local theater. Their popcorn and drink purchases were recorded in the two-way table shown.

The number of student who purchased popcorn are 56 while the total number of students is 156. Thus, the relative frequency is,

[tex]f_r=\dfrac{56}{156}\\f_r=0.3589\\f_r=35.89\%[/tex]

Thus, the relative frequency of students who purchased popcorn in a movie at the local theater is 35.89%.

Answer:

664 ft²

Step-by-step explanation:

The rectangular yard has dimensions 36 ft by 55 ft.

The area of the yard is 36 ft × 55 ft = 1980 ft²

The walkway inside the fence is 4 ft wide. The area inside the walkway has dimensions

36 ft - 2 × 4 ft = 28 ft

55 ft - 2 × 4 ft = 47 ft

The area of the rectangle inside the walkway is 28 ft × 47 ft = 1316 ft²

The area of the walkway is the difference between the total area enclosed by the fence and the rectangle inside the walkway.

area of walkway = 1980 ft² - 1316 ft² = 664 ft²

The length of PC is 3.

If a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.

Given: BA = 5, AP = 4 and DP = 12.

PB= BA+AP= 9

Using tangent- secant theory

PA*PB= PC*PD

4*9= PC* 12

36= 12PC

PC= 36/12

PC= 3

Hence, length of PC is 3.
