Answer:

Step-by-step explanation:

Answer:

[tex](x^{3} + 9\, x^{2} + 14\, x - 12)[/tex].

Step-by-step explanation:

Let [tex]p(x)[/tex] denote the polynomial in question.

The question states that dividing [tex]p(x)[/tex] by [tex](x + 3)[/tex] gives the quotient [tex](x^{2} + 6\, x - 4)[/tex] (with no remainder.) In other words:

[tex]\displaystyle \frac{p(x)}{x + 3} = x^{2} + 6\, x - 4[/tex].

Multiply both sides by [tex](x + 3)[/tex] to find an expression for the polynomial in question, [tex]p(x)[/tex]:

[tex]p(x) = (x^{2} + 6\, x - 4)\, (x + 3)[/tex].

Expand this expression to obtain:

[tex]\begin{aligned}p(x) &= (x^{2} + 6\, x - 4) \, (x + 3) \\ &= x\, (x^{2} + 6\, x - 4) \\ & \quad + 3\, (x^{2} + 6\, x - 4) \\ &= x^{3} + 6\, x^{2} - 4\, x \\ &\quad + 3\, x^{2} + 18\, x - 12 \\ &= x^{3} + 9\, x^{2} + 14\, x - 12\end{aligned}[/tex].

Step-by-step explanation:

[tex]4 > -(-4)-4\\4 > 4-4\\4 > 0[/tex]Answer:

Step-by-step explanation:

just substitute the coordinates into the inequality and solve it.

[tex](-4) > -(-4)-4\\-4 > 4-4\\-4 > 0[/tex]This is false, therefore, (-4,-4) is incorrect

[tex]0 > -(-4)-4\\0 > 4-4\\0 > 0[/tex]0 cannot be greater than 0, therfore (-4,0) is incorrect

[tex]-4 > -(0)-4\\-4 > -4[/tex]-4 cannot be greater than -4, therefore (0,-4) is incorrect

[tex]4 > -(-4)-4\\4 > 4-4\\4 > 0[/tex]4 is greater than 0 and therefore, (-4,4) is the correct answer

Alternatively, you can draw a graph of the inequality, by considering [tex]y=-x-4[/tex], drawing its graph, and substitute a point that's not on the line, for example, (0,0), to find the region the inequality is in. If the coordinate you substituted in solves the inequality, then the region you choose is the one that the point you substituted in lies in. If the inequality is incorrect, its the other region on the other side of the graph. Once that's done, you can observe if any of the coordinates listed in the question correspond correctly to the relative regions on the graph, and thus choose the correct answer from there.

Answer:

h = 16.5

Step-by-step explanation:

Remark

The formula below really is the Pytharagan formula disguised.

h^2 = hypotenuse (side)^2 - (1/2 side)^2

Givens

side = 19 cm

Solution

h^2 = 19^2 - (1/2*19)^2      Substitute given into formula

h^2 = 361 - (9.5)^2            square 9.5

h^2 = 361 - 90.25             Subtract

h^2 = 270.75                    Take the square root of both sides

√h^2 = √270.75

Answer: h = 16.5

Answer:

19 cubic centimeters

Step-by-step explanation:

The equation for the volume of a sphere is [tex](4/3)\pi r^3[/tex].

We can setup the equation as [tex]29307 = \frac{4}{3}\pi r^3[/tex].

Now we need to isolate the r^3.  Divide both sides by 4/3 and pi, which leaves [tex]\frac{29307}{(4/3) \pi } =r^3[/tex]

Now we take the cube root of both sides to have a single r on the right side.  This comes out to equal 19 cm^3

Answer:

10.47 to the nearest hundredth

Step-by-step explanation:

By Pythagoras

c^2 = 2^2 + 4^2 = 20

c = √20

c = 4.47

Perimeter = 2 + 4 + 4.472

The perimeter of the right-angled triangle is 6 + 2√(5) feet.

Pythagoras' Theorem states that the square of the hypotenuse side of a right-angled triangle is equal to the sum of the squares of the other two sides.

Given that a right-angled triangle.

The perpendicular length is 2 feet, the base length is 4 feet.

We need to use the Pythagorean theorem to find the length of the hypotenuse, and then add up the lengths of all three sides to get the perimeter.

In this case, we can use it to find the length of the hypotenuse c:

2² + 4² = c²

4 + 16 = c²

20 = c²

c = √(20) = 2√(5)

Now we can add up the lengths of all three sides to get the perimeter:

Perimeter = a + b + c

Perimeter = 2 + 4 + 2√(5)

Perimeter = 6 + 2√(5) feet

Therefore, the perimeter = 6 + 2√(5) feet

Step-by-step explanation:

The answer is all the days added together and then divided by 10.

20+30+40+38+25+22+39+22+26+31=293.

293/10=29.3

Answer:

length * width * height = volume

10 * 2 * 5.5 = 110 cubed inches

Answer:

Step-by-step explanation:

For the first problem you have:

[tex]sin^2(x)-sin(x)=0[/tex]

Factor out a sin(x) to get:

[tex]sin(x)[2sin(x)-1]=0[/tex]

Individually, set both terms equal to zero:

[tex]sin(x)=0[/tex]

[tex]2sin(x)-1-0[/tex]

The first equation is asking "sine of what angle gives zero?" The sine of 0 will give zero, and so will the sine of pi, and 2pi, etc. Therefore, you can generalize this by saying the solution is pi multiplied by an integer 'n' where 'n' can be from zero to infinity:

[tex]x=n\pi[/tex]

where n = 0, 1, 2, 3, 4, 5, etc..

(make sure you specify that 'n' can equal zero.)

For the second equation, add 1 to both sides to get:

[tex]2sin(x)=1[/tex]

Divide both sides by 2 to get:

[tex]sin(x)=\frac{1}{2}[/tex]

Sine of what gives 1/2? Sine of pi/6 gives 1/2, and so does 5pi/6. Therefore, the two solution here would be pi/6 plus a phase shift of 2pi, and 5pi/6 plus a phase shift of 2pi:

[tex]x=\frac{\pi }{6} +2n\pi[/tex]

[tex]x=\frac{5\pi }{6} +2n\pi[/tex]

The second problem states that:

[tex]cos(u)=\frac{4}{5}[/tex]

Cosine is defined as the adjacent side of a right triangle divided by the hypotenuse of the right triangle:

[tex]cos(u)=adjacent/hypotenuse[/tex]

After drawing a triangle, the adjacent side is 4, and the hypotenuse is 5. But first, lets rewrite sin(2u) using the double angle identity to get:

[tex]sin(2u)=2sin(u)cos(u)[/tex]

But we know the value of cosine of 'u', it is 4/5. Therefore:

[tex]sin(2u)=2sin(u)*\frac{4}{5}[/tex]

[tex]sin(2u)=\frac{8}{5} sin(u)[/tex]

To find the sine of 'u', use the triangle you should have constructed when I defined cosine as the adjacent over the hypoptenuse. Sine is defined as the opposite over the hypotenuse. We have:

[tex]sin(u)=opposite/hypotenuse[/tex]

We have the adjacent, we have the hyppotenuse, and we want the opposite. If we find the opposite side, we can find the sin(2u). Use pythagogrean's theorem to find the opposite:

[tex]adjacent^2+opposite^2=hypotenuse^2[/tex]

[tex]4^2+opposite^2=5^2[/tex]

[tex]opposite^2=25-16[/tex]

[tex]opposite=3[/tex]

Finally, we have that:

[tex]sin(u)=\frac{3}{5}[/tex]

Or:

[tex]sin(2u)=\frac{8}{5}*\frac{3}{5} =24/25[/tex]

Hopefully you could follow along. There is a lot going on here, but since youre in pre-calc, you should be able to follow along as long as you follow my steps.

Answer:

x=4

Step-by-step explanation:

20x-5x=65-5

15x=60

x=60/15

x=4

Answer:

Step-by-step explanation:

In the question we are given with an equation that is 20x + 5 = 5x + 65 . And we are asked to find the value of x.

Solution :

[tex] \longmapsto \: 20x + 5 = 5x +65[/tex]

Step 1 : Subtracting 5 on both sides :

[tex] \longmapsto \: 20x + \bold{ \cancel{5}} - \bold{ \cancel{5}}= 5x + \bold{65 }- \bold{5}[/tex]

On further calculations, we get :

[tex] \longmapsto \: 20x = 5x + 60[/tex]

Step 2 : Subtracting 60 on both sides :

[tex] \longmapsto \:20x - 60 = 5x + \bold{ \cancel{60}}- \bold{ \cancel{60}}[/tex]

On further calculations, we get :

[tex] \longmapsto \:20x - 60 = 5x[/tex]

Step 3 : Transposing 5x to left hand side and -60 to right hand side :

[tex] \longmapsto \:20x - 5x = 60[/tex]

On further calculations , we get :

[tex] \longmapsto \:15x = 60[/tex]

Step 4 : Divide by 15 on both sides :

[tex] \longmapsto \: \frac{ \cancel{15}x}{ \cancel{15} } = \cancel{ \frac{60}{15} }[/tex]

On further calculations, we get :

[tex] \longmapsto \: \red{ \boxed{x = 4}}[/tex]

Now, we are verifying our answer by substituting value of x in given equation :

Therefore , our answer is correct
