What is the remainder when f(x)=x^3+7x^2+9x-5 is divided by (x+4)

Answers

Answer 1

On dividing (x³ + 7x² + 9x - 5) by (x + 4), we get -

h(x) = x² + 3x - 3 + 7/(x + 4).

What is Division algorithm?

Division algorithm states that -

Dividend = (Divisor x Quotient) + Remainder

Given is to find the remainder when -

(x³ + 7x² + 9x - 5) ÷ (x + 4)

We can write -

f(x) = (x³ + 7x² + 9x - 5)

g(x) = (x + 4)

So -

h(x) = f(x) ÷ g(x)

h(x) = (x³ + 7x² + 9x - 5) ÷ (x + 4)

h(x) = (x³ + 4x² + 3x² + 9x - 5)/(x + 4)

h(x) = x² + (3x² + 9x - 5)/(x + 4)

h(x) = x² + 3x + (-3x - 5)/(x + 4)

h(x) = x² + 3x - 3 + 7/(x + 4)

Therefore, on dividing (x³ + 7x² + 9x - 5) by (x + 4), we get -

h(x) = x² + 3x - 3 + 7/(x + 4).

A bus traveled on a level road for 6 hours at an average speed 20 miles per hour faster than it traveled on a winding road The time spent on the winding road was 3 hours Find the average speed on the level road the entire trip was 534 miles


The bus’s speed was on the level road was ( ) mph?

Answers

The bus’s speed on the level road was 72 mph if the bus traveled on a level road for 6 hours at an average speed of 20 miles per hour.

The given data is as follows:

The bus traveled on road time = 6 hours

Average speed = 20 miles/hour

Time spent on the winding road = 3 hours

Entire trip distance =  534 miles

The equation will be written as:

(x+20) * (6) + (x)(2) = 534

Now, "x" is the average speed on the winding road.

solving for x value,

6x + 120 + 2x = 534

8x = 534 -120

x = 414/8

x = 52

Now,  we calculated the average speed for the winding road.

The average speed for the level road is calculated as:

u1 + v1 = 52 + 20 = 72

Therefore we can conclude that the bus’s speed on the level road was 72 mph.

Answers

The extraneous solutions of the equation (1)/(x+2)+(3)/(x+7)=(5)/(x²+9x+14) are x = 0, x = -7, and x = -14

To solve this equation, we must first simplify each side of the equation and then use the rule of equality. We can do this by finding the least common denominator (LCD) of the equation. In this case, the LCD is (x+2)(x+7)(x²+9x+14).

To simplify each side, we must multiply each term by the LCD divided by its original denominator. This leaves us with:

(x+2)(x+7)(x^2+9x+14) / (x+2) + (x+2)(x+7)(x²+9x+14) / (x+7) = (x+2)(x+7)(x²+9x+14) / (x²+9x+14)

We can now apply the rule of equality to solve the equation:

x³+11x²+37x+98 = 0

To find the solution of the equation, we must now factor the left side of the equation. We can do this by first factoring out a common factor of x, which gives us:

x(x²+11x+98) = 0

We can now factor the remaining trinomial, which gives us:

x(x+7)(x+14) = 0

Therefore, the extraneous solutions of the equation are: x = 0, x = -7, and x = -14

So, the LU-factorization of the given matrix is:

LU = `[1 0 0 0]` `[4 0 1 8]`

`[0.25 1 0 0]` `[0 1 -4.25 6]`

`[0 4.25 1 0]` `[0 0 1.25 -2]`

`[0 0 -1.25 1]` `[0 0 0 1]`

The LU-factorization of a matrix is a method of decomposing a matrix into a lower triangular matrix (L) and an upper triangular matrix (U). The L matrix must have a unit diagonal, meaning that all the entries on the main diagonal are equal to 1.

To find the LU-factorization of the given matrix, we can use the following steps:

1. Begin with the given matrix:

`[4 0 1 8]`

`[1 1 -4 10]`

2. Use Gaussian elimination to transform the matrix into an upper triangular matrix (U):

`[4 0 1 8]` → `[1 1 -4 10]` → `[0 1 -4.25 6]` → U = `[0 0 1.25 -2]`

3. Now, we can use the entries from the Gaussian elimination to create the lower triangular matrix (L):

L = `[1 0 0 0]`

`[0.25 1 0 0]`

`[0 4.25 1 0]`

`[0 0 -1.25 1]`

The first step in the industrial recovery of zinc from zinc sulfide ore is roasting. That is the conversion of ZnS to ZnO by heating: 2ZnS (s)- 30₂(g) → 2ZnO(s) - 250, (g) AH=-879 kJ/mol Calculate the heat (in kJ) associated with roasting 6.00 grams of zinc sulfide. Round your answer to 3 significant digits.​

Answers

The heat associated with roasting 6.00 g of zinc sulfide is 27.1 kJ.

How to solve this

The molar mass of ZnS is 97.45 g/mol, which means that 6.00 g of ZnS is equal to:

6.00 g ZnS × (1 mol ZnS/97.45 g ZnS) = 0.0616 mol ZnS

According to the balanced equation, the roasting of 2 mol of ZnS releases 879 kJ of heat:

2 ZnS (s) + 3 O₂ (g) → 2 ZnO (s) + 2 SO₂ (g) ΔH = -879 kJ/mol

Therefore, the roasting of 0.0616 mol of ZnS releases:

(879 kJ/mol) × (0.0616 mol ZnS / 2 mol ZnS) = 27.1 kJ

Therefore, the heat associated with roasting 6.00 g of zinc sulfide is 27.1 kJ. Rounded to three significant digits, the answer is 27.1 kJ.

Using some rules for interior angles, we will see that:

x = 22.5

y = 22.5

How to find the values of x and y?

Remember that the sum of the interior angles of any triangle is 180°.

Now, we can see that :

3x + k = 180°

Where k is the missing angle in the left triangle.

k = 180° - 3x

if we add the 3 interior angles, we will get:

2x + y + 180° - 3x = 180°

y - x = 0°

So x and y have the same value.

If now use the top triangle, we can write:

(90 - y) + 3x + 2x = 180

And we know that y = x

90 -x  + 3x + 2x = 180

90 + 4x = 180

4x = 180 - 90  =90

x = 90/4 = 22.5

Answers

A. The equation given can be expressed in polar form using the Pythagoras theorem.
Let the polar coordinate of a point be (r, θ).
Let r = √(x^2 + y^2)
=> r^2 = x^2 + y^2
=> r^2 = 2x^2 - 6xy - 2x
Let θ = tan^-1 (y/x)
Now, the equation in polar form is:

r^2 = 2x^2 - 6xy - 2x

tan^-1 (y/x) = θ


To find the exact values, solve the equation for the given values of x and y:


For x = 0 and y = 2:

r^2 = 0 - 6*2 - 0

=> r^2 = -12

=> r = √12

=> r = 2√3

tan^-1 (2/0) = θ

=> θ = 90°

Hence, the point (x, y) = (0, 2) has polar coordinates (2√3, 90°).

B. The given cycle has a period of 12 hours. This means that the time between each high and low tide is 12 hours. The height of high tide is 6 feet and the height of low tide is 2 feet. This means that the amplitude of the cycle is 4 feet (6 feet - 2 feet).

Hence, the equation for the tide cycle can be expressed as:

Using the circumference formula of the circle, we know that the area of the shaded region is 2,375 in.


What is the circumference?

The circumference of a circle is the distance encircling its edge.

The diameter of a circle is the distance measured through its center.

The radius of a circle is the distance from the center to any point on the edge.

The circumference of a circle or ellipse in geometry is its perimeter.

That is, if the circle were opened up and straightened out to a line segment, the circumference would be the length of the arc.

The curve length around any closed figure is more often referred to as the perimeter.

So, the circumference of the inner circle is 125.6 inches.

Then, the radius would be:

C = 2πr

125.6 = 2πr

125.6 = 6.28r

r = 125.6/6.28

r = 20 in

r for the outer circle: r will be 20 + 14 = 34 in

Area of the inner circle:

A = π20²

A = 1256.63706

A = 1257 in

A = πr²

A = π34²

A = 3631.68111

A = 3632 in

Area of the shaded region:

Using properties of rectangles:

The rectangle has two whole diagonals that intersect to form triangles. As a property of rectangles, diagonals are always congruent. Since the diagonals bisect each other and are congruent, each half of the two diagonals are also congruent. This forms an Isosceles Triangle.

Applying Theorems of Triangles:

If a triangle has a pair of congruent opposite sides leading to the vertex, then the base angles opposite those sides are also congruent. This is the Isosceles Triangle Theorem. So, sides DE and EC are congruent, meaning the two base angles must both measure 31°. Now, we can apply the Triangle Sum Theorem, which states the three interior angles in a triangle sum up to 180°. Let’s create an equation using this theorem to solve for m∠DEC.

Find the zeros and find the multiplicity of each zero for the function f(x)=(3x+2)^(5)(x^(2)-10x+25)

Answers

The zeros and their multiplicities are x=-2/3, multiplicity 5 and x=5, multiplicity 1.

To find the zeros of the function f(x)=(3x+2)^(5)(x^(2)-10x+25), we need to set the function equal to zero and solve for x.

0=(3x+2)^(5)(x^(2)-10x+25)

Since the product of two factors is zero, one of the factors must be zero. We can set each factor equal to zero and solve for x.

(3x+2)^(5)=0

3x+2=0

3x=-2

x=-2/3

The other factor is:

x^(2)-10x+25=0

This is a quadratic equation, which we can solve using the quadratic formula:

x=(-b±√(b^(2)-4ac))/(2a)

x=(-(-10)±√((-10)^(2)-4(1)(25)))/(2(1))

x=(10±√(100-100))/2

x=(10±0)/2

x=10/2

x=5

So the zeros of the function are x=-2/3 and x=5.

To find the multiplicity of each zero, we need to look at the exponent of the factor that contains the zero. The zero -2/3 comes from the factor (3x+2)^(5), which has an exponent of 5, so the multiplicity of -2/3 is 5. The zero 5 comes from the factor (x^(2)-10x+25), which has an exponent of 1, so the multiplicity of 5 is 1.

Therefore, the zeros and their multiplicities are:

x=-2/3, multiplicity 5

x=5, multiplicity 1

Lin's sister has a checking account. If the account balance ever falls below zero, the bank charges her a fee of $5.95 per day. Today, the balance in Lin's sister's account is −$2.67.

If she does not make any deposits or withdrawals, what will be the balance in her account after 22 days?
Type the answer in the box below.

Answers

If Lin's sister dοes nοt make any depοsits οr withdrawals, the balance in her accοunt after 22 days will be -$133.57.

What is meant by accοunt balance?  

The balance is the sum οwing οn an accοunt in banking and accοunting. The term "balance" in bοοkkeeping refers tο the difference between the tοtal οf debit entries and the tοtal οf credit entries made intο an accοunt οver the cοurse οf a certain financial periοd. The accοunt shοws a debit balance when tοtal debits exceed tοtal credits.

Net debt is represented by an accοunt balance that is less than zerο. An accοunt with a minus sign (-) at the end οf the amοunt typically has a negative balance οr is in debt.

Given,

The fee charged when the balance falls belοw zerο = $5.95/day

The current balance in Lin's sister's accοunt = −$2.67

We are asked tο find her accοunt balance after 22 days if nο transactiοns are made.

Since the current balance in her accοunt is belοw zerο, a fee will be charged.

The fee charged fοr 22 days = 5.95 × 22 = $130.9

Then the current balance = -2.67 - 130.9 = -$133.57

Therefοre if Lin's sister dοes nοt make any depοsits οr withdrawals, the balance in her accοunt after 22 days will be -$133.57.

solve the equations in problems 31−46 by completing the square. 31. x^2-2x-8 = 0
32. x^2-4x-9 = 0
33. x^2+6x4 = 0
34. x^2+x-4 = 0
35. x^2-3x+1 =0

Answers

The solutions for the given equations are:

31. x = 4 or x = -2

32. x = 2+√13 or x = 2-√13

33. x = -3+√5 or x = -3-√5

34. x = -0.5+√4.25 or x = -0.5-√4.25

35. x = 1.5+√1.25 or x = 1.5-√1.25

To solve the equations by completing the square, we will use the following steps:

Step 1: Move the constant term to the right side of the equation.

Step 2: Take half of the coefficient of the x term and square it.

Step 3: Add this value to both sides of the equation.

Step 4: Factor the left side of the equation.

Step 5: Take the square root of both sides of the equation.

Step 6: Solve for x.

Let's apply these steps to the given equations:

31. x^2-2x-8 = 0

Step 1: x^2-2x = 8

Step 2: (-2/2)^2 = 1

Step 3: x^2-2x+1 = 9

Step 4: (x-1)^2 = 9

Step 5: x-1 = ±3

Step 6: x = 4 or x = -2

32. x^2-4x-9 = 0

Step 1: x^2-4x = 9

Step 2: (-4/2)^2 = 4

Step 3: x^2-4x+4 = 13

Step 4: (x-2)^2 = 13

Step 5: x-2 = ±√13

Step 6: x = 2+√13 or x = 2-√13

33. x^2+6x+4 = 0

Step 1: x^2+6x = -4

Step 2: (6/2)^2 = 9

Step 3: x^2+6x+9 = 5

Step 4: (x+3)^2 = 5

Step 5: x+3 = ±√5

Step 6: x = -3+√5 or x = -3-√5

34. x^2+x-4 = 0

Step 1: x^2+x = 4

Step 2: (1/2)^2 = 0.25

Step 3: x^2+x+0.25 = 4.25

Step 4: (x+0.5)^2 = 4.25

Step 5: x+0.5 = ±√4.25

Step 6: x = -0.5+√4.25 or x = -0.5-√4.25

35. x^2-3x+1 = 0

Step 1: x^2-3x = -1

Step 2: (-3/2)^2 = 2.25

Step 3: x^2-3x+2.25 = 1.25

Step 4: (x-1.5)^2 = 1.25

Step 5: x-1.5 = ±√1.25

Step 6: x = 1.5+√1.25 or x = 1.5-√1.25

Therefore, the solutions for the given equations are:

31. x = 4 or x = -2

32. x = 2+√13 or x = 2-√13

33. x = -3+√5 or x = -3-√5

34. x = -0.5+√4.25 or x = -0.5-√4.25

35. x = 1.5+√1.25 or x = 1.5-√1.25

Which function represents a horizontal dilation of the function y = log x ? Select all that apply.

Answers

The functions that represent a horizontal dilation of the function y = log x are A and C.

What is horizontal dilation?

Horizontal dilation, also known as horizontal stretching or compression, is a transformation of a function that changes the shape of its graph by scaling the independent variable (x-axis).

When a function is horizontally dilated, it is stretched or compressed horizontally without changing its vertical position. If the function is stretched horizontally, it becomes flatter and wider, while if it is compressed horizontally, it becomes steeper and narrower.

Horizontal dilation is achieved by multiplying the independent variable x in the function by a positive constant a. If a > 1, the function is horizontally compressed, and if 0 < a < 1, the function is horizontally stretched. If a = 1, the function is not affected by horizontal dilation.

The function that represents a horizontal dilation of the function y = log x is a function of the form y = log(ax), where a is a positive constant. This is because changing the value of a will stretch or compress the graph horizontally.

A. h(x) = log(2x) + 1 represents a horizontal compression by a factor of 2, followed by a vertical translation upward by 1 unit.

B. K(x) = log(x + 1) represents a horizontal translation to the left by 1 unit.

C. f(x) = log(0.3x) represents a horizontal compression by a factor of 1/0.3 = 3.33.

D. g(x) = 5 log(x) represents vertical stretching by a factor of 5.

Therefore, the functions that represent a horizontal dilation of the function y = log x are A and C.

Shot Down A cruise missile is traveling straight across the desert at 548 mph at an altitude of 1 mile, as shown in the figure.
A gunner spots the missile coming in his direction and fires a projectile at the missile when the angle of elevation of the missile is 35°. If the speed of the projectile is 688 mph, then for what angle of elevation of the gun will the projectile hit the missile?

Answers

The elevation of the gun will the projectile hit the missile will be 62.18°.

What is trigonometry?

Trigonometric functions examine the interaction between the dimensions and angles of a triangular form.

Let 't' be the time. And 'θ' be the angle. Then the measure of the angle is given as,

688t / sin 35° = 548 / sin θ

sin θ = 0.4568

θ = 27.18°

The angle from the base is calculated as,

⇒ 27.18° + 35°

⇒ 62.18°

The elevation of the gun will the projectile hit the missile will be 62.18°.
