Answer:

54 cm

Step-by-step explanation:

The area (A) of an equilateral triangle is

A = [tex]\frac{s^2\sqrt{3} }{4}[/tex]  ( s is the side length ) then

[tex]\frac{s^2\sqrt{3} }{4}[/tex] = 81[tex]\sqrt{3}[/tex] ( multiply both sides by 4 to clear the fraction )

s²[tex]\sqrt{3}[/tex] = 324[tex]\sqrt{3}[/tex] ( divide both sides by [tex]\sqrt{3}[/tex] )

s² = 324 ( take the square root of both sides )

s = [tex]\sqrt{324}[/tex] = 18

Thus

perimeter = 3 × 18 = 54 cm

Answer:

  1/12

Step-by-step explanation:

The slope of a ramp (or anything else) is the ratio of its "rise" to its "run."

The rise is the vertical change. Here, that is shown as 3 m.

The run is the horizontal change. Here, that is shown as 36 m.

Then the slope is ...

  [tex]\text{slope }=\dfrac{\text{rise}}{\text{run}}=\dfrac{3\text{ m}}{36\text{ m}}=\boxed{\dfrac{1}{12}}[/tex]

Additional comment

If this were a line on a graph, the slope would be calculated the same way. When the rise is positive to the right, the slope is positive. On a graph, if the rise is negative as you go to the right, the slope is negative.

A) -5

Step-by-step explanation:

-5 is less than -4 since the number is bigger but there is a negative. -3,0, and 2 are bigger, not smaller.

Answer:

We conclude that at x = 0 and x = -1, the value of f(x) = 2ˣ - 1 and g(x) = 1/2x is the same.

Therefore, the solution to f(x) = g(x) is:

Step-by-step explanation:

Given the table

x                f(x) = 2ˣ - 1                  g(x) = 1/2x

-2                  -3/4                               -1

-1                    -1/2                               -1/2

0                     0                                   0

1                       1                                   1/2

2                     3                                    1

If we carefully observe, we can determine that

at x = 0, the value of f(x) = 2ˣ - 1 and g(x) = 1/2x is the same.

In other words,

at x = 0

Thus,

at x = 0

f(x) = g(x)

Also at x = -1, the value of f(x) = 2ˣ - 1 and g(x) = 1/2x is the same.

In other words,

at x = -1

Thus,

at x = -1

f(x) = g(x)

Summary:

Thus, we conclude that at x = 0 and x = -1, the value of f(x) = 2ˣ - 1 and g(x) = 1/2x is the same.

Therefore, the solution to f(x) = g(x) is:

Answer:

The coordinates of  D(5,2)

Step-by-step explanation:

Step(i):-

Given point C(1,-4) and mid point M( 3,-1)

we have to use mid-point formula

          [tex](\frac{x_{1}+x_{2} }{2} ,\frac{y_{1}+y_{2} }{2} )[/tex]

Step(ii):-

Given mid point M( 3,-1) and (x₂ , y₂ ) be the 'D' co-ordinates

                [tex](\frac{1+x_{2} }{2} ,\frac{-4+y_{2} }{2} ) = (3,-1)[/tex]

          ⇒  [tex]\frac{1+x_{2} }{2} = 3[/tex]        and  [tex]\frac{-4+y_{2} }{2} = -1[/tex]

           1 + x₂ = 3 ˣ 2      and  -4 +y₂ = -2

   ⇒     x₂ = 6-1 =5         and    y₂ = -2 +4

  ⇒     x₂  = 5   and y₂ = 2

Final answer:-

The coordinates of 'D' = (5,2)

DEFG and KLMN are parallelograms.

A parallelogram is a simple quadrilateral with two pairs of parallel sides.

The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.

K(2, 7), L(6, 12), M(13, 13) and N(9, 8).

Slope of KL=12-7/6-2

=5/4

Slope of MN=8-13/9-13

=-5/-4=5/4

Slope of KN=8-7/9-2=1/7

Slope of LM=13-12/13-6=1/7

The opposite sides having same slope.

KLMN is a parallelogram.

Now D(-5,-6), E(5,2), F(4, -4), G(-6, -12)

Distance=√(x₂-x₁)²+(y₂-y₁)²

DE=√(5+5)²+(2+6)²

=√100+64=√164

FG=√100+64=√164

EF=√(4-5)²+(-4-2)²

=√1+36 =√37

DG=√1+36=√37

DE=FG and EF=DG

The sides are parallel

Hence, the DEFG and KLMN are parallelograms.

Answer:

for #1 its the 1st and 4th box

for # 2 it's 13.5 and 20.25

Step-by-step explanation:

1st box - 10 ÷ 5 = 2 and 25 ÷ 5 = 5

4th box - 10 x 2 = 20 and 25 x 2 = 50

you have to make sure that you do the same thing for both sides of the equation

6 x 2.25 = 13.5

9 x 2.25 = 20.25

Answer:

41.8°

Step-by-step explanation:

Resolvemos esta pregunta usando la regla del seno

a / sin A = b / sin B

Estamos despejando el ángulo B

Por lo tanto:

3 / sin 30 = 4 / sin B

Cruz multiplicar

3 × sin B = sin 30 × 4

sin B = sin 30 × 4/3

B = arco sin [sin 30 × 4/3]

B = 41.81031 °

Answer:

(6, –3)

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

Dilation is the reduction or enlargement of the size of an object by a factor.

If an object with point A(x, y) is dilated about the center of origin by a factor k, the new point is A'(kx, ky)

From the question, the coordinate if the triangle ABC is at A(-1, 2), B(-1, -1) and C(2, -1).

Since the new triangle has sides with three times length, hence it is dilated by a factor of 3. The new coordinates are:

A' = 3(-1, 2) = (-3, 6)

B' = 3(-1, 1) = (-3, 3)

C' = 3(2, -1) = (6, -3)

Answer:

f(x) = 4(2/3)ˣ represents exponential decay.

Hence, option D is the correct function.

Step-by-step explanation:

The function of the form

[tex]y\:=\:a\left(1\:-\:r\right)^x\:\:[/tex]

where [tex]a > 0[/tex] and [tex]0 < r < 1[/tex]

is called the exponential decay function.

If we replace base 'b' by 1 - r, then we get the decay function of the form

y = abˣ

where 0 < b < 1

Now, if we carefully observe, the function f(x) = 4(2/3)ˣ is the only option correct as

f(x) = 4(2/3)ˣ

here  0 < b < 1  and a > 0

Therefore, f(x) = 4(2/3)ˣ represents exponential decay.

Hence, option D is the correct function.

The function that represents exponential decay is [tex]f(x)=4(\frac{2}{3} )^x[/tex] since 2/3 is less than 1.

The standard expression for an exponential function is expressed as:

[tex]y=ab^x[/tex]

From the given options, we can see that the function that represents exponential decay is [tex]f(x)=4(\frac{2}{3} )^x[/tex] since 2/3 is less than 1.

The answer is below

Step-by-step explanation:

The question is not correct, a similar question is:

A specific shade of red nail polish requires 7 parts red to 2 parts yellow. A mixture contains 35 quarts of red and 8 quarts of yellow. How can you fix the mixture to make the correct shade of red?

Solution:

A ratio is used in comparing amount of things, showing how the size of thing is compared to the other thing.

Given that:

[tex]Ratio\ of\ red\ nail\ polish=\frac{7\ quarts\ of\ red}{2\ quarts\ of\ yellow} \\\\Ratio\ of\ red\ nail\ polish=\frac{7\ quarts\ of\ red}{2\ quarts\ of\ yellow}*\frac{4}{4} =\frac{28\ quarts\ of\ red}{8\ quarts\ of\ yellow}\\\\Ratio\ of\ mixture\ given\ =\frac{35\ quarts\ of\ red}{8\ quarts\ of\ yellow}\\\\\frac{28\ quarts\ of\ red}{8\ quarts\ of\ yellow}\neq \frac{35\ quarts\ of\ red}{8\ quarts\ of\ yellow}\\\\ \\[/tex]

Therefore to make the correct shade of red, an additional of 7 quarts of red is needed.

A sequence can be arithmetic or geometric sequence

The function that defines the sequence is f(n) = 10 -3n

The sequence is given as:

7,4,1,-2,-5...

The above sequence is an arithmetic sequence, with an initial value of 7, and a common difference of -3.

So, the function is:

[tex]a_n = a +(n -1)d[/tex]

This gives

[tex]a_n = 7 +(n -1)(-3)[/tex]

[tex]a_n = 7 +3 -3n[/tex]

[tex]a_n = 10 -3n[/tex]

Hence, the function that defines the sequence is f(n) = 10 -3n
