Answer:

The function given is non-linear.

Step-by-step explanation:

The slope between (0, 2) and (2,6):

[tex]\frac{6-2}{2-0}=\frac{4}{2}=\boxed{2}[/tex]

The slope between (2,6), and (3, 12):

[tex]\frac{12-6}{3-2}=\frac{6}{1}=\boxed{6}[/tex]

Since the slopes are not equal to each other, the function is non-linear. A linear function's slope must stay consistent.

Hope this helps.

Answer:

[tex]\text{D. }108^{\circ}[/tex]

Step-by-step explanation:

The sum of the interior angles of a polygon with [tex]n[/tex] sides is given by [tex]180(n-2)[/tex].

A pentagon is a shape with 5 sides and 5 angles. Therefore, the sum of its interior angles is equal to:

[tex]180(5-2),\\180\cdot 3=540^{\circ}[/tex]

Regular polygons can be defined as polygons with equal side lengths and angles. Therefore, to find the measure of each interior angle of a regular polygon, divide the sum of the interior angles (540 degrees) by the number of angles the polygon has (5 sides).

Therefore, each interior angle in a regular polygon has a measure of:

[tex]\frac{540}{5}=\boxed{108^{\circ}}[/tex]

Each interior angle in a regular polygon has a measure of is 108°. Therefore, option D is the correct answer.

We can find the number of sides in a polygon using the value of interior angle. Interior angle = 180°(n-2)/n, where n is the number of sides of the polygon.

The sum of the interior angles of a polygon with n sides is given by 180(n-2).

A pentagon is a shape with 5 sides and 5 angles. Therefore, the sum of its interior angles is equal to:

180(5-2) =540°

Therefore, option D is the correct answer.

Answer:

The right answer is:

(a) [tex]P(t) = P_o \ e^{0.03536t}[/tex]

(b) [tex]t = 14 \ years \ 6 \ months[/tex]

(c) [tex]P(t) = =621,595.6[/tex] ($)

Step-by-step explanation:

Given:

House price increment rate,

= 3.6% annually

(a)

Let the exponential equation will be:

⇒ [tex]P(t) = P_o e^{Kt}[/tex]

here,

t = 0

P = P₀

t = 1 yr

then,

[tex]P(1) = P_o +3.6 \ persent \ P_o[/tex]

        [tex]=1.036 \ P_o[/tex]

now,

⇒ [tex]1.036 P_o = P_o \ e^{K.1}[/tex]

 [tex]ln(1.036) = K[/tex]

            [tex]K = 0.03536[/tex]

Thus, the exponential equation will be "[tex]P(t) = P_o \ e^{0.03536t}[/tex]".

(b)

We know,

[tex]P_o = 600,000[/tex] ($)

[tex]P(t) = 10,00,000[/tex] ($)

∵ [tex]P(t) = P_o \ e^{0.03536t}[/tex]

   [tex]1000000=600000 \ e^{0.03536 t}[/tex]

              [tex]\frac{5}{3}= e^{0.03536 t}[/tex]

        [tex]ln(\frac{5}{3} )=0.03536 t[/tex]

       [tex]\frac{\frac{0.5}{0825} }{0.03536} =t[/tex]

                [tex]t = 14.45 \ years[/tex]

or,

                [tex]t = 14 \ years \ 6 \ months[/tex]

(c)

[tex]P_o=600,000[/tex] ($)

[tex]t = 1 year[/tex]

Now,

⇒ [tex]P(t) = P_o \ e^{0.03536 t}[/tex]

           [tex]=600000 \ e^{ 0.03536\times 1}[/tex]

           [tex]=621,595.6[/tex] ($)

Answer:

-36,36

Step-by-step explanation:

3x - 6(5x + 3) = 9x + 6

 Distribute:

3x - 30x - 18 = 9x + 6

Combine like terms:

-27x - 18 = 9x + 6

There are two possible ways to isolate x

On the left

Subtract 9x from each side

-27x - 18 -9x = 9x-9x + 6

-36x -18 = 6

On the right

Add 27x from each side

-27x - 18 +27x = 9x+27x + 6

-18 =36x+ 6

Answer:

The answers are option B and E.

Answer:

k ≥ 4

Step-by-step explanation:

A Quadratic equation is given to us and we need to find out the value of k for which the equation has real roots. The given equation is ,

[tex]\rm\implies kx^2 +4x +1=0[/tex]

With respect to Standard form of Quadratic equation :-

[tex]\rm\implies ax^+bx+c=0[/tex]

For real roots ,

[tex]\rm\implies Discriminant = b^2-4ac\geq 0[/tex]

Substitute the respective values ,

[tex]\rm\implies b^2-4ac \geq 0\\[/tex]

[tex]\rm\implies 4^2 - 4(k)(1) \geq 0 \\[/tex]

Simplify the LHS ,

[tex]\rm\implies 16 - 4k \geq 0 \\[/tex]

Add 4k both sides ,

[tex]\rm\implies 4k\geq 16 [/tex]

Divide both sides by 4 ,

[tex]\rm\implies \boxed{\blue{\rm k \geq 4}}[/tex]

Answer:

b is the answer

Step-by-step explanation:

Answer:

Step-by-step explanation:

I'll get you the answer. You pick it from what you are given.

The slope of the perpendicular is m1 * m2 = - 1

m1 = 3

m2 = -1 / m1

m2 = -1 / 3

So far what you have is

y = (-1/3) x + b

Use the point go get b

x = -1

y = - 3

y = (-1/3) *x + b

-3 = (-1/3)*-1 + b

-3 = 1/3 + b  

-3 - 1/3 = b

b = -3.33333  or

b = -3 1/3

b = -10/3              

So the answer is

y = (- 1/3) x - 10/3            or

y = (-1 / 3)x - 3.3333       or

y = (-1/3 )x  - (3 1/3)

Answer:

true, to my knowledge concentric circles are just circles that all have one main center.

Step-by-step explanation:

Answer:

x = 40

y= 20

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

sin theta = opp / hyp

sin 60 = 20 sqrt(3)/ x

x sin 60 = 20 sqrt(3)

x = 20 sqrt(3)/ sin 60

x = 20 sqrt(3)/ sqrt(3)/2

x = 20 *2

x = 40

tan theta = opp /adj

tan 60 = 20 sqrt(3)/y

y = 20 sqrt(3)/ tan 60

y = 20 sqrt(3) / sqrt(3)

y = 20

Answer:

108 degrees

Step-by-step explanation:

an arithmetic progression means that there is a constant inbetween all of the angles. Since the smallest angle is 12 degrees, ( i just guessed and checked) and came up with the angles :

12, 60, 108

these have a constant of 48

Answer:

108°

Step-by-step explanation:

Since the angles are in arithmetic progression , then the angles are

a + a + d + a + 2d

a is the first term and d the common difference

Sum the angles and equate to 180 with a = 12

a + a + d + a + 2d = 180

12 + 12 + d + 12 + 2d = 180 , that is

36 + 3d = 180 ( subtract 36 from both sides )

3d = 144 ( divide both sides by 3 )

d = 48

Then the largest angle is

a + 2d = 12 + 2(48) = 12 + 96 = 108°

Given:

The table that shows the relationship of the total number of pieces of fruit to the number of bananas.

To find:

Why is [tex]\dfrac{6}{5}[/tex] not equivalent to [tex]\dfrac{3}{2}[/tex].

Solution:

If a, b, c are real numbers, then

[tex]\dfrac{a}{b}=\dfrac{a\times c}{b\times c}[/tex]

The given fraction is [tex]\dfrac{3}{2}[/tex]. It can be written as:

[tex]\dfrac{3\times 2}{2\times 2}=\dfrac{6}{4}[/tex]

The number 3 is multiplied by 2 to get 6. So, the 2 should also be multiplied by 2. The ratio should be [tex]\dfrac{6}{4}[/tex], not [tex]\dfrac{6}{5}[/tex].

Therefore, the correct option is A.

Answer:

Step-by-step explanation:

Answer:

(x-9)^2 +(y-12)^2 = 225

Step-by-step explanation:

First find the length of the radius

If is the distance from the center to the point

d = sqrt( (x2-x1)^2 + (y2-y1)^2 )

   = sqrt( (0-9)^2 + (0-12)^2)

   = sqrt ( 81+144)

  = sqrt(225)

  = 15

The equation for a circle is

( x-h) ^2+ (y-k)^2 = r^2

(x-9)^2 +(y-12)^2 = 15^2

(x-9)^2 +(y-12)^2 = 225

A) With 8 council members, the polygon formed with the triangles will be an octagon.

The final shape should look just like the one you posted with your question.

B) The individual pieces should be isosceles triangles. The three angles of each triangle should measure 45°, 67.5° and 67.5°.

We need two sides of the triangles to be the same. The base of the triangle's length will depend on the number of triangles we are using to form the final polygon.

The number of triangles will define the angle between the two sides of equal length. You can find this by dividing 360° into the number of triangles:

[tex]\frac{360^{o}}{8}=45^{o}[/tex]

The other two angles should measure the same, so we can find them by subtracting the 45° from 180° (which is what we get when adding the three angles of any triangle) and then dividing the answer into 2.

180°-45°=135°

[tex]\frac{135^{o}}{2}=67.5^{o}[/tex]

C) The sum of the measures of the internal angles of the final shape should add up to 360°, that way we can guarantee that the figure is closed:

45°+45°+45°+45°+45°+45°+45°+45°=360°

D)

D.B) The individual pieces should be isosceles triangles. The three angles of each triangle should measure 36°, 72° and 72°.

The number of triangles will define the angle between the two sides of equal length. You can find this by dividing 360° into the number of triangles:

[tex]\frac{360^{o}}{10}=36^{o}[/tex]

The other two angles should measure the same, so we can find them by subtracting the 36° from 180° (which is what we get when adding the three angles of any triangle) and then dividing the answer into 2.

180°-36°=144°

[tex]\frac{144^{o}}{2}=72^{o}[/tex]

C) The sum of the measures of the internal angles of the final shape should add up to 360°, that way we can guarantee that the figure is closed:

36°+36°+36°+36°+36°+36°+36°+36°+36°+36°=360°
