Answer 1

Answer:

Perimeter of the sector = (36 + 8π) cm.

Step-by-step explanation:

Formula to find the of an arc of the circle is,

Length of the arc = [tex]\frac{\theta}{360}(2\pi r)[/tex]

Here, θ = central angle formed by the arc

r = radius of the circle

Therefore, length of the arc given in the picture = [tex]\frac{80}{360}(2\pi) (18)[/tex]

                                                                                = 8π cm

Perimeter of the sector = Sum of all sides of the sector

                                       = Length of radius + length of the arc + length of radius

                                       = 18 + 8π + 18

                                       = (36 + 8π) cm

Perimeter of the sector is (36 + 8π) cm.

The shifting of graph depends on value of b.

[tex]y = mx + b[/tex]

If b > 0, the graph shifts up.

If b = 0, the graph passes origin point.

If b < 0, the graph shifts down.

The only thing that's matter if the graph shifts up or down is about if the value of b is in negative or positive.

9x+y=2
−4x−y=−17

Answers

Answer: x = -3    y = 29

Step-by-step explanation:

9x + y = 2

-4x - y = -17

5x = -15

Divide both sides by 5

x = -3

9x + y = 2

Substitute -3 for x

9 (-3) + y = 2

-27 + y = 2

Add 27 to both sides

y = 29

Answer:

x = 60, y = 25

Step-by-step explanation:

Δ ABC has 3 congruent sides and is equiangular, thus

the 3 angles are congruent, all 60°

x = 60

∠ ABC and ∠ CBD are adjacent and supplementary, sum to 180° , then

∠ CBD = 180° - 60° = 120°, so

y = 180 - (120 + 35) = 180 - 155 ← sum of angles in triangle

y = 25

Why do the roots of a quadratic equation have the opposite sign of the factors of a quadratic equation

Answers

Answer:

To find the roots of the quadratic equation we set the factors of the quadratic equation equal to 0.

Step-by-step explanation:

Consider the provided information.

Roots of the equation is x-intercepts or zeros of the given equation.

So, By definition, the value of The y-coordinate is zero for points situated on the x-axis.

Thus, we can find the roots of a quadratic function, by putting f (x) = 0.

Now, let (x-a)(x-b) is the factor of any quadratic equation.

To find the roots of the quadratic function we will put our factor equal to 0.

[tex](x-a)(x-b)=0[/tex]

Now by the zero product property either x-a=0 or x-b=0

[tex]x-a=0[/tex] then [tex]x=a[/tex]

or

[tex]x-b=0[/tex]  then [tex]x=b[/tex]

So, we can say that to find the roots of the quadratic equation we set the factors of the quadratic equation equal to 0.

If (3a + 3b + 1) (3a + 3b - 1) = 80, then what is a + b?

Answers

Answer: a + b = 3 -        maybe

Step-by-step explanation:

( 3a + 3b + 1 )( 3a + 3b - 1 ) = 80

Expand

9a² + 9ab - 3a + 9ab + 9b² - 3b + 3a + 3b - 1 = 80

Simplify

9a² + 9b² + 18ab - 1 = 80

move the 1 over

9a² + 9b² + 18ab = 81

divide by 9

a² + b² + 2ab = 9

not really sure after this part

move the 2ab over

a² + b² = 9 - 2ab

square root both sides

a + b =  

simplify

a + b = 3 -
