rotated 90 degrees counterclockwise about the origin to form the quadrilateral A'B'C'D'. What are the signs of the coordinates (x,y) of point C'? 
A: (-4,4)
B: (3,6)
C: (3,2)
D: (-2,-2)

Then quadrilateral A’B’C’D is reflected across the x-axis to form quadrilateral A’’B’’C’’D’’. What are the signs of the coordinates (x,y) of point B’’?

Answer:

[tex]\text{D. The terms may be combined.}[/tex]

Step-by-step explanation:

Recall that [tex]\sqrt{a\cdot b}=\sqrt{a}\cdot\sqrt{b}[/tex]. Using this, we can simplify and combine the two terms:

[tex]6\sqrt{32}-12\sqrt{72},\\=6\cdot \sqrt{4}\cdot \sqrt{8}-12\cdot \sqrt{9}\cdot \sqrt{8},\\=6\cdot 2\cdot \sqrt{8}-12\cdot 3\cdot \sqrt{8},\\=12\sqrt{8}-36\sqrt{8},\\=-24\sqrt{8}=-24\cdot\sqrt{4}\cdot\sqrt{2}=\boxed{-48\sqrt{2}}[/tex]. Therefore, the terms may be combined.

Answer:

x ≈ 31.0°

Step-by-step explanation:

From the right triangle given in the picture,

By applying tangent rule,

tan(x) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

tan(x) = [tex]\frac{9}{15}[/tex]

x = [tex]\text{tan}^{-1}(\frac{9}{15} )[/tex]

x = [tex]\text{tan}^{-1}(0.6)[/tex]

x = 30.96

x ≈ 31.0°

Therefore, measure of angle x is 30.0°

Step-by-step explanation:

Answer:

first option

Step-by-step explanation:

In a parallelogram consecutive angle are supplementary, sum to 180, so

2a + 122 = 180 ( subtract 122 from both sides )

2a = 58 ( divide both sides by 2 )

a = 29

---------------

In a parallelogram the opposite sides are congruent, then

b + 6 = 10 ( subtract 6 from both sides )

b = 4

Answer:

[tex]x =2m {}^{2} - 2p[/tex]

Answer:

Step-by-step explanation:

[tex]p=m^{2}-\frac{x}{2}\\\\p+\frac{x}{2}=m^{2}\\\\\frac{x}{2}=m^{2}-p\\\\x = 2*(m^{2}-p)\\\\x = 2m^{2}-2p[/tex]

Answer:

3x^2 - 7x +4

Step-by-step explanation:

see step on the file joint

The quotient of 9x³ - 21x² + 12x divided by 3x is  3x² - 7x + 4.

We know that if x = a is one of the roots of a given polynomial x - a = 0 is a factor of the given polynomial.

To confirm if x - a = 0 is a factor of a polynomial we replace f(x) with f(a) and if the remainder is zero then it is confirmed that x - a = 0 is a factor.

Given, A cubic polynomial 9x³ - 21x² + 12x and being divided by 3x.

So, (9x³ - 21x² + 12x)/(3x).

= 9x³/3x - 21x²/3x + 12x/3x.

= 3x² - 7x + 4.

So, The quotient when 9x³ - 21x² + 12x and being divided by 3x is

3x² - 7x + 4.

Step-by-step explanation:

Answer:

y-9=-5/2(x+6)

Step-by-step explanation:

y-y1=m(x-x1)

y-9=-5/2(x-(-6))

y-9=-5/2(x+6)

An equation in point-slope form for this line would be y-9=-5/2(x+6).

The equation of the straight line has its slope and given point.

If we have a non-vertical line that passes through any point(x1, y1) has gradient m. then general point (x, y) must satisfy the equation

y-y₁ = m(x-x₁)

Which is the required equation of a line in a point-slope form.

Thus,

y-y1= m(x-x1)

A line passes through the point (-6,9) and has a slope of -5/2 So,

y-9=-5/2(x-(-6))

y-9=-5/2(x+6)

Hence, an equation in point-slope form for this line would be y-9=-5/2(x+6).

Answer: 127.5km

Step-by-step explanation:

We are informed that Ron cycled 510km last week and that he was under the rain for the 25percent of his journey.

The distance travelled did under the rain will be gotten by multiplying 25% by 510km. This will be:

= 25% × 510

= 0.25 × 510

= 127.5km

He was in the rain for 127.5km
