The difference between the two polynomials is 11x²3y³ - 4xy².

The difference between two polynomials is the result you get by subtracting one from the other.

Thus:

= (4x²2y³ + 2xy² – 2y) – (–7x²y³ + 6xy² – 2y)

= 4x²2y³ + 2xy² – 2y + 7x²y³ - 6xy² + 2y

= 11x²3y³ - 4xy²

Answer:

Step-by-step explanation: 679miles/5days =135.8miles/days

I hope it help

If they take 5 days to drive 679 miles to Seattle. Then the number of miles that they drive each day will be 135.8 miles per day.

The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.

We know that the speed formula

Speed = Distance/Time

They take 5 days to drive 679 miles to Seattle.

Then the number of miles that they drive each day will be

→ 679 / 5

→ 135.8 miles per day.

The statement(s) that are true is that the measure of the reference angle is 45°.

The conversion of an angle in radian to a degree can be determined by the multiplication of the given angle in radian by 180/π.

From the given information:

[tex]\mathbf{\theta = \dfrac{7 \pi}{4}}[/tex]

To degrees, we have:

[tex]\mathbf{\theta = \dfrac{7 \pi}{4} \times \dfrac{180}{\pi}}[/tex]

[tex]\mathbf{\theta =315^0}[/tex]

A reference angle is an angle that measures the remaining distance (called the terminal distance) to the x-axis.

315° is in the 4th quadrant, i.e.

= 360° - 315°

= 45°

Explanation:

This is something you could do by trial and error.

The visible numbers are 1,2,3,4,6 which multiply to 144.

Another approach is to notice that 5 is not a factor of 144, so it must be the hidden value not part of the items multiplied.

Every other number 1,2,3,4,6 is a factor of 144.

1*144 = 144

2*72 = 144

3*48 = 144

Answer:

5 / 16

Step-by-step explanation:

For a question such as this, we most often simply use a calculator. However, I suppose that to do this by hand you would do as follows:

0.025 / 0.080

= 0.005  / 0.016

= 100 * (0.005 / 0.016)

= 5 / 16

The first step is a simplification. Both the numerator and denominator are divisible by 0.005.  In the next step, we can multiply the numerator and denominator both by 100 to get whole numbers. Because we multiply each by the same number, we have not changed the value of the original fraction. This leaves us with 5 / 16.

As there is the highest degree 4 there are four zeros .

Using calculator

the roots are(attached)

The graph is also attached

Answer:

a) 4 roots

b) x = 1 and x = -3

[tex]\textsf{c)} \quad x=1, \quad x=-3, \quad x=\dfrac{-1 + \sqrt{3}i}{2}, \quad x=\dfrac{-1 - \sqrt{3}i}{2}[/tex]

d) see attached

Step-by-step explanation:

Given function:

[tex]f(x)=x^4+3x^3-x-3[/tex]

Part (a)

From inspection of the function, the highest exponent of the polynomial is 4.  Therefore, it is expected that the polynomial will have 4 roots.

Part (b)

To find the rational roots, find values of x where [tex]f(x)=0[/tex]

[tex]f(1)=(1)^4+3(1)^3-1-3=0[/tex]

[tex]f(-3)=(-3)^4+3(-3)^3-(-3)-3=0[/tex]

Therefore, the rational roots are: x = 1 and x = -3

Part (c)

As there are only 2 rational roots, the other 2 roots must be complex roots. To find these, first factor the polynomial using the 2 rational roots found in part (b):

[tex]\implies f(x)=(x-1)(x+3)(x^2+bx+1)[/tex]

[tex]\implies f(x)=(x^2+2x-3)(x^2+bx+1)[/tex]

[tex]\implies f(x)=x^4+bx^3+x^2+2x^3+2bx^2+2x-3x^2-3bx-3[/tex]

[tex]\implies f(x)=x^4+(2+b)x^3+(2b-2)x^2+(2-3b)-3[/tex]

Compare coefficients to find b:

[tex]\implies (2+b)x^3=3x^3[/tex]

[tex]\implies b=1[/tex]

Therefore the fully factored function is:

[tex]\implies f\:\!(x)=(x-1)(x+3)(x^2+x+1)[/tex]

Therefore:

[tex](x^2+x+1)=0[/tex]

To find the complex roots, use the quadratic formula

[tex]x=\dfrac{-b \pm \sqrt{b^2-4ac} }{2a}\quad\textsf{when }\:ax^2+bx+c=0[/tex]

[tex]\implies x=\dfrac{-1 \pm \sqrt{1^2-4(1)(1)}}{2(1)}[/tex]

[tex]\implies x=\dfrac{-1 \pm \sqrt{-3}}{2}[/tex]

[tex]\implies x=\dfrac{-1 \pm \sqrt{3}\sqrt{-1}}{2}[/tex]

[tex]\implies x=\dfrac{-1 \pm \sqrt{3}i}{2}[/tex]

Therefore, all the roots of the function are:

[tex]x=1, \quad x=-3, \quad x=\dfrac{-1 + \sqrt{3}i}{2}, \quad x=\dfrac{-1 - \sqrt{3}i}{2}[/tex]

Part (d)

End behaviors:

As the degree of the function is even and the leading coefficient is positive, the end behaviors are:

[tex]\textsf{As } x \rightarrow - \infty, \:\: f(x) \rightarrow + \infty[/tex]

[tex]\textsf{As } x \rightarrow + \infty, \:\: f(x) \rightarrow + \infty[/tex]

y-intercept

Substitute x = 0 into the function:

[tex]f\:\!(0)=(0)^4+3(0)^3-(0)-3=-3[/tex]

Therefore, the y-intercept is (0, -3)

To find the approximate x-coordinates of the turning points (stationary points), differentiate the function, set it to zero, then solve for x:

[tex]f'\:(x)=4x^3+9x^2-1[/tex]

[tex]\implies 4x^3+9x^2-1=0[/tex]

Using a calculator, x ≈ -2.2, x ≈ -0.4, x ≈ 0.3

Therefore the approximate coordinates of the turning points are:

(-2.2, -9.3),  (-0.4, -2.7)  and (0.3, -3.2)

We don't need to plot these points, they merely help us with the approximate shape of the curve.

Answer: 15.9

Step-by-step explanation:

The measure of minor arc BC is equal to ∠BPC which is 147 degrees.

An equation is an expression that shows the relationship between two or more variables and numbers.

From the diagram:

4k + 159 = 2k + 153 (vertical opposite angles are equal)

4k + 159 = 2k + 153

k = -3

Arc Bc = 4k + 159 = 4(-3) + 159 = 147

The measure of minor arc BC is equal to ∠BPC which is 147 degrees.

Step-by-step explanation:

Answer:

1.6 to nearest tenth.

Step-by-step explanation:

This will be a line which is perpendicular to y = 3x + 5 and the line will also pass through the point (0,0).

Equation of that line:

Slope = -1/3  so we can write:

y - 0 = -1/3(x - 0)

So its y = -1/3 x,

The point where it intersects with  the given line is now found:

-1/3x = 3x + 5

10/3 x = -5

x = -5 *3/10 =  -1.5.

- and the y coordinate = 3(-1.5) + 5 = 0.5.

So the point is (-1.5, 0.5)

and the required distance = √((-1.5)^2 + 0.5^2)

=  1.58

= 1.6 to nearest tenth.

Answer:

M=3ft

Step-by-step explanation:

Use trigonometric ratio Sin to get M which is the opposite side of the given angle of 30°

[tex]sin = \frac{opp}{hyp} [/tex]

Multiply 6 on both sides:

[tex]6sin30 = m[/tex]

3=M

or..

use special angles:

Sin30=0.5

6×0.5=3

Therefore M is 3 ft
