The other roots of the cubic equation p(x) = 24·x³ - 46·x³ + 29·x - 6 are;

x = 1/2

x = 3/4

A cubic equation is an equation  that has 3 as the highest index.

The specified polynomial in the question is presented as follows;

P(x) = 24·x³ - 46·x² + 29·x - 6

The solution of the equation is; x =  (2/3)

Therefore, (x - 2/3) is a factor of the equation and we get;

(24·x³ - 46·x² + 29·x - 6) ÷ (x - 2/3)  has a remainder of 0

Dividing the above expression using long division, we get;

                    24·x²  - 30·x + 9

(x - 2/3)  \({}\)     |(24·x³ - 46·x² + 29·x - 6)

               \({}\)     24·x³ - 16·x² + 29·x  - 6

                \({}\)              -30·x²

            \({}\)                   -30·x² + 20·x

                          \({}\)                      9·x - 6

                        \({}\)                        9·x - 6

The other real roots of the specified equation can be found as follows;

The equation for the roots is; P(x) = 24·x³ - 46·x² + 29·x - 6 = 0

From the above long division, therefore;

24·x³ - 46·x² + 29·x - 6 = (24·x²  - 30·x + 9) × (x - 2/3) = 0

Which indicates; (24·x² - 30·x + 9) = 0 or (x - 2/3) = 0

The other solution are;

24·x³ - 30·x + 9 = 0

3·(·8·x² - 10·x + 3) = 0

8·x² - 10·x + 3 = 0

Solutions for the above equation in the form; a·x² + b·x + c = 0 can be obtained using the quadratic formula as follows;

The quadratic formula; x = \(\dfrac{-b\pm\sqrt{b^2 - 4\cdot a\cdot c} }{2\cdot a}\)

By comparing the equation, 8·x² - 10·x + 3 = 0 to the equation, a·x² + b·x + c = 0, we get;

a = 8, b = -10, and c = 3

Therefore;

x = (10 ± √((-10)² - 4 × 8 × 3))/(2 × 8)

((-10)² - 4 × 8 ×3) = 2

Therefore;

x = (10 ± √((-10)² - 4 × 8 × 3))/(2 × 8) = (10 ± 2)/(16)

x = 3/4, and x = 1/2

Therefore, the other other roots in increasing sequence are;

x = 1/2 and x = 3/4

Answer:

1.35/0.15

13.5/1.5

Step-by-step explanation:

We know the first and last ones are incorrect. The last is incorrect because it uses addition when the question is asking for the quotient. The first is incorrect because 1.35/1.5 = 0.9. The quotient (or answer) for the rest all equal 9.

1.35/0.15 = 9

13.5/1.5 = 9

The Venn diagram for (D ⋃ E) ⋃ F will be the ovarlapped region of D,E and F.

To represent the sets D, E, and F in the Venn diagram, we first construct three overlapping circles. Then, beginning with the innermost operation and moving outward, we shade the regions corresponding to the set operations in the expression.

We shade the area where the circles for D and E overlap because the equation (D ⋃ E)  denotes the union of the sets D and E. All the elements in D, E, or both are represented by this area.

The union of (D ⋃ E) with F is the next step. This indicates that we darken the area where the circle for F crosses over into the area that we shaded earlier. All the components found in sets D, E, F, or any combination of these sets are represented in this region.

The final Venn diagram should include three overlapping circles, with (D ⋃ E) ⋃ F shaded in the area where all three circles overlap.

$6.4

Step-by-step explanation:

Given the data :

Car Age (years) Selling Price ($000) Car Age (years) Selling Price ($000)

1 9 8.1 7 8 7.6

2 7 6 8 11 8

The estimated regression equation using a linear regression calculator is :

y = -0.47876X + 11.17724

With - 0.47876 being the slope ; and 11.17724 being the intercept

y = predicted variable (price of car) ; x = predictor variable (Age of car)

Selling price of a 10 year old car : x = 10

ŷ = -0.47876(10) + 11.17724

Price = 6.38964

About 6.4(000) dollars ($6,400)

According to the regression equation : The starting price of cars is about $11.18 (intercept) with the proved of cars declining by a value of $0.479(negative slope value) each year.

Answer: 880 oz

Step-by-step explanation:

We want to write it in the same units, let's use oz as our common unit.

1 gal = 128 oz

then 5 gal = 5*128 oz = 640 oz

1 qt = 32 oz

then 6 qt = 6*32 oz = 192 oz

Then we have:

640 oz + 192 oz + 48 oz = 880 oz

The value of standard notation is,

⇒ 880 oz

We have to given that,

Measures are,

⇒ 5 gal 6qt 48 oz

We have to change it into standard notation as,

We want to write it in the same units, let's use oz as our common unit.

1 gal = 128 oz

then 5 gal = 5 x 128 oz = 640 oz

1 qt = 32 oz

then 6 qt = 6 x 32 oz = 192 oz

Then we have:

⇒ 5 gal 6qt 48 oz

⇒ 640 oz + 192 oz + 48 oz

⇒ 880 oz

Answer: old machine 150, new machine 280

Step-by-step explanation:

given data:

Old machine = 25t

New machine = 35t

where t = hrs

we dont know the time for old machine so we assume it to be ( t ),

while that of the new machine is ( 14-t ) hours for new machine, and sum of 430 components.

therefore;

25t +490 - 35t = 430

-10t = -60

divide both sides by -10

t = 6 hours for the first machine.

6hrs * 25 components /hr

= 150 component parts For old machine.

for new machine

= 14 - t ........... eq1.

where ( t = 6 ), substitute t into the equation

= 14 - 6

= 8 hours for the second machine

= 8 * 35

= 280 components parts

Step-by-step explanation:

Answer: 803.84cm3

Step-by-step explanation:
The formula for finding the volume of a cylinder is πr2h.
In other words, the area of the top face's circle times the height.

To find the circle's area, we first find the radius of the circle. Since the diameter is 8cm, we divide by 2 to get the radius, which is 4cm.

4cm squared is 4cm x 4cm, which is 16cm. 16cm times 3.14 is 50.24cm squared.

Now, we have the area of the circle. 50.24cm squared!

The height is 16cm, so to find the cylinder, we times the area of the circle by the height of the cylinder! So,

16cm x 50.24cm squared = 803.84cm cubed.

The volume of the can of soup is 803.84cm cubed.

Step-by-step explanation:

Answer:

By applying law of conservation of mass.

Explanation:

Every balanced chemical equation follows law of conservation of mass.

This law states that mass can neither be created nor can be destroyed but it can only be transformed from one form to another form.

This law also states that the total number of individual atoms on the reactant side must be equal to the total number of individual atoms on the product side.

For the given reaction, the balanced chemical equation follows:

4Na1+Pb(SO4)__Pb14+2Na2SO4

On reactant side:

Number of sodium atoms = 4

Number of iodine atoms = 4

Number of lead atoms = 1

Number of sulfur atoms = 2

Number of oxygen atoms = 8

On product side:

Number of sodium atoms = 4

Number of iodine atoms = 4

Number of lead atoms = 1

Number of sulfur atoms = 2

Number of oxygen atoms = 8

Hence, the balanced chemical equation is written above.

Step-by-step explanation:

a) The distance from point P to the pole  is: 6.2 m

b) The height of the Pole is: 6.2 m

The triangle attached shows us the triangle formed as a result of the given word problem about angle of elevation and distance and height.

Now, we are given that:

The angle of elevation of the top of the pole =  45°

Angle of elevation of the top of the pole = 58°.

|PQ|= 10m

a) PR is distance from point P to the pole and using trigonometric ratios, gives us:

PR/sin 58 = 10/sin(180 - 58 - 45)

PR/sin 58 = 10/sin 77

PR = (10 * sin 58)/sin 77

PR = 8.7 m

b) P O can be calculated with trigonometric ratios as:

P O = PR * cos 45

P O = 8.7 * 0.7071

P O = 6.2 m

Now, the two sides of the isosceles triangle formed are equal and as such:

R O = P O

Thus, height of pole R O = 6.2 m
