Answers

The image of the point after the rotation is (-5, 7)

What is a 270 degrees rotation?

A 270 degrees rotation is a rotation that has the same effect as the 90 degrees counterclockwise of a figure.

How to determine the image of the rotation?

The coordinate of the point is given as

H = (-7, 5)

The rotation is given as 270° clockwise

As mentioned above,

The algebraic rule of its rotation to be changed from (x, y) to (-y, x) i.e. (x, y) => (-y, x)

So, we have

(x, y) => (-y, x)

Substitute (-7, 5) in (x, y) => (-y, x)

So, we have

(-7, 5) => (-5, 7)

Rewrite as

H' =(-5, 7)

Hence, the coordinates of the image using the rotation rule is (-5, 7)

We evaluate the function at 0, pi/2, and 2pi.

[tex]\begin{gathered} y(0)=-3\sin 0=0 \\ y(\frac{\pi}{2})=-3\sin \frac{\pi}{2}=-3 \\ y(2\pi)=-3\sin 2\pi=0 \end{gathered}[/tex]

Does the table show a proportional relationship? If so, what is the value of y when x is 3/5?

Answers

There is a directly proportional relationship between "x" and "y" which is y=5x i.e., for every "x", value of "y" is "5x" hence the value of "y" if value of x=3/5 will be y = 3.

As per the question statement, we are supposed to find out a proportional relationship between "x" and "y" and also find the value of "y" when x=3/5.

After observing the given data, we conclude that y = 5x i.e., for every value of "x", value of "y" is "5x".

So we derive a formula y = 5x and the proportionality constant is 5

Now when x = 3/5

Then by the formula, y = 5x,

y = 5*(3/5)

y = 3

Hence, there is a directly proportional relationship between "x" and "y" which is y=5x i.e., for every "x", value of "y" is "5x" hence the value of "y" if value of x=3/5 will be y = 3.

According to Descartes's rule of sign, how many possible positive and negative roots are there for the equation 0=-4x^6 - 3x^5+2x² - 4x +1? Drag the choices to the boxes to correctly complete the table.

Answers

[tex] -4x^6 - 3x^5+2x^2 - 4x +1 = 0[/tex] has 1 or 3 Positive roots and one only Negative roots.

Descartes' rule of sign.

Function has the same number of positive real zeroes as there are number of changes in the sign of the coefficients, or an even number less than the found number.

Now, here the given expression is : p(x) = [tex] -4x^6 - 3x^5+2x^2 - 4x +1 [/tex]

Now here, the number of sign changes are:

First : + to - in [tex] - 3x^5 => + 2x^2 [/tex]

Second : - to + in [tex]+2x² => - 4x [/tex]

Third: + to - in [tex] - 4x => +1 [/tex]

So, the total sign changes = 3

⇒ The total positive roots of p(x) = 3 or a EVEN NUMBER LESS THAN 3 = 1.

So, p(x) has either 3 or 1 POSITIVE ROOTS.

⇒ The number of negative roots p(x) has is either 4 or 6.

Hence has 1 or 3 Positive roots.

Now I look at f (−x). That is, having changed the sign on x, I'm now doing the negative-root case:

p(-x) = [tex] -4(-x)^6 - 3(-x)^5+2(-x)^2 - 4(-x) +1 [/tex]

= [tex] -4x^6 + 3x^5+2x^2 + 4x + 1 [/tex]

the number of sign changes are:

First : + to - in [tex] -4x^6 => +3x^5 [/tex]

So, the total sign changes = 1.

so there is exactly one negative root. (In this case, I don't try to count down by two's, because the first subtraction would give me a negative number.)

Hence has 1 or 3 Positive roots and one only Negative roots.

what is the answer to 13 /5/6 - 17 /3/8

Answers

When the fractions, 13 5/6 and 17 3/8 are subtracted, the answer would be -3 ⁵ / ₁₂

How to subtract mixed fractions?

To subtract mixed fractions, the first thing to do is to convert the mixed fraction to an improper fraction.

To convert improper fractions, multiply the denominator by the whole number and then add the numerator. The result would be the numerator.

Converting the fractions gives:

13 5/6 = 83 / 6

17 3/8 = 139 / 8

Subtracting these fractions then gives:

= 83 / 6 - 139 / 8

Find a common denominator for 6 and 8 which will be 24 as this is their lowest common multiple.

Then, divide 24 by the denominator and multiply the result by the numerator of the fraction:

= 332 / 24 - 417 / 24

= -85 / 24

= - 3¹⁰ /₂₄

= -3 ⁵ / ₁₂

In conclusion, the answer would be -3 ⁵ / ₁₂

5(2x − 4)= 10x − 20Solve for x

Answers

5(2x − 4)= 10x − 20

5*2x - 5*4 = 10x - 20

10x - 20 = 10x - 20

10x = 10x

Any real value attributed to x satisfies this equation. Therefore, there are infinite solutions to this equation.

Answer: X= (-∞,∞)

Step-by-step explanation:

Simplifying

5(2x + -4) = 10x + 20

Reorder the terms:

5(-4 + 2x) = 10x + 20

(-4 * 5 + 2x * 5) = 10x + 20

(-20 + 10x) = 10x + 20

Reorder the terms:

-20 + 10x = 20 + 10x

Add '-10x' to each side of the equation.

-20 + 10x + -10x = 20 + 10x + -10x

Combine like terms: 10x + -10x = 0

-20 + 0 = 20 + 10x + -10x

-20 = 20 + 10x + -10x

Combine like terms: 10x + -10x = 0

-20 = 20 + 0

-20 = 20

Solving

-20 = 20
