The evergreen tree grew 2.4 feet taller the next year.

Percentage can be derived by dividing the given value by the total value, and then multiplying the result by 100.

Percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%".

Percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100.

It is given by:

Percentage = (given value / total value) * 100%

From the question, the tree has a base height of 20m, if it grew 20% taller then;

tree height = 12 x (20/100)

tree height = 12 x 0.2

tree height = 2.4

Therefore, the tree grew 2.4 feet taller the next year.

The value of the obtuse angle by applying sine rule for the attached diagram is equal to x° = 38.2°.

As given in the question,

Diagram of the obtuse angle triangle is attached.

In the given triangle,

Name the vertex of angle x as 'C' and side opposite to angle x as AB.

Draw a perpendicular from point A to BC at point D such that AD = z .

Given m ∠ACB = x°

AB = 2y

AC = y

m ∠ABC = 18°

In ΔADB,

sinB = AD / AB

⇒ sin 18° = z / 2y __(1)

In ΔACD,

sin ACD = AD / AC

⇒ sin ( 180 - x )° = z  / y  __(2)

Divide (1) by (2) we get,

sin18° / sin ( 180 - x )° = ( z / 2y ) / ( z / y )

⇒ sin 18° / sinx° = 1 / 2

⇒ sinx° = 2sin18°

⇒ sinx° = 2 (0.309 )

⇒ x° = sin⁻¹( 0.618)

⇒x° =  38.2°

Therefore, the obtuse angle for the given attached diagram using sine rule is equal to 38.2°.

Answer:

The length of the side of the square should be 10ft

Step-by-step explanation:

Calculation of the length of the side:

Since A square has an area of 40 square feet.

As we know that the square does have 4 sides

So, the length of the side of the square should be

40 divided by 4

= 10ft

The length of the perimeter of the rectangle = 112 cm or 44 inches

Given in the question,

Area = [tex]105in^{2}[/tex]

= 677.4 [tex]cm^{2}[/tex]

Length of one side of the rectangle = 7 inches

= 17.7 cm

∴ Since the length of one side of the rectangle is given in the question we need to find the width of the rectangle to calculate the total perimeter of the rectangle

⇒ Area = length x width

⇒ 677.4 = 17.7 x width

⇒ Width = [tex]\frac{Area}{Length}[/tex]

⇒ Width = [tex]\frac{677.4}{17.7}[/tex]

⇒ Width = 38.2 cm

As we got both the length and the width of the rectangle, now we can calculate the perimeter,

⇒ Perimeter = [tex]2( length + width)[/tex]

⇒ Perimeter = [tex]2(17.7 + 38.3)[/tex]

⇒ Perimeter = 2 x 56 cm

⇒ Perimeter = 112 cm

⇒ In inches = 44 inches

Therefore, the length of the perimeter is = 112cm or 44 inches

Answer:

x=16

y=10

Step-by-step explanation:

(8x-14) + (5y+16) =180, because together they make a straight line.

(5x+34) = (8x-14), because they are alternate exterior angles.

Solve for x:

48=3x

x=16

Let's plug that into the first equation, then solve for y.

(8(16)-14) + (5y+16) =180

128-14+5y+16=180

130+5y=180

5y=50

y=10

Combinations are sometimes known as selections. Combinations are the results of selecting elements from a set assortment. Nothing specific is being organized here. We are choosing them. To denote the number of unique r-selections or combinations among a set of n items, we write n C r. Combinations are distinct from arrangements or permutations.

Here,

The first two numbers in this three-term series are 17 and 24, and the third one remains a mystery.

Given that there are 40 options for the third number and that each try takes 10 seconds, we have 40 x 10 seconds, or 400 seconds, to try every possible combination.

Answer: Second Pic, Probably the third.

Step-by-step explanation: little bit of guesswork

Answer:

Therefore, when s is equal to 30, t is equal to 30 / 5 = <<30/5=6>>6.

Step-by-step explanation:

Direct variation means that the ratio between two variables is always constant. In this case, the constant ratio between s and t is equal to 20/4 = 5. This means that when t is equal to 4, s is equal to 20 and the ratio between the two is 5. If s is equal to 30, we can find the corresponding value of t by setting up the following equation:

s / t = 5

We can then solve for t by multiplying both sides of the equation by t to get:

s = 5 * t

If we substitute 30 for s, we get:

30 = 5 * t

We can solve for t by dividing both sides of the equation by 5:

t = 30 / 5

Therefore, when s is equal to 30, t is equal to 30 / 5 = <<30/5=6>>6.

Answer:

A = 2; B = 3; C = -3

Step-by-step explanation:

The curve goes to negative infinity as x decreases and positive infinity as x increases.

This looks like a 3rd degree polynomial.

f(0) = -3

f(x) = Ax^B + x + C

f(0) = A(0^B) + 0 + C = -3

C = -3

f(x) = Ax^B + x - 3

f(1) = A(1^B) + 1 - 3 = 0

A - 2 = 0

A = 2

f(x) = 2x^B + x - 3

f(1.125) = 2(1.125)^B + 1.125 - 3 = 1

2(1.125)^B + 1.125 - 3 = 1

2(1.125)^B = 2.875

(1.125)^B = 1.4375

log (1.125)^B = log 1.4375

B × log (1.125) = log 1.4375

B = (log 1.4375)/(log 1.125)

B = 3

f(x) = 2x^B + x - 3

Answer:

After rotating the ordered pairs 90° counterclockwise around the origin, they will become:

(3, -2)

(-7, -4)

(-4, 5)

(-6, 8)

To rotate a point 90° counterclockwise around the origin, you can use the following transformation matrix:

[[0, -1],

[1, 0]]

To rotate a point (x, y) by 90° counterclockwise, you can multiply the transformation matrix by the point, which will give you the new coordinates of the point after the rotation. For example, to rotate the point (2, 3) 90° counterclockwise, you can multiply the transformation matrix by the point:

[[0, -1],

[1, 0]] * [2, 3] = [3, -2]

Similarly, you can rotate the other points 90° counterclockwise using the same transformation matrix.

The Variable x varies inversely with y, and x = 132 when y = 4 then the value of x is 16.5 when y = 32.

So, the correct option is option(D).

Inverse variation can be expressed by the formula, xy=k or y=kx

That is, if there is a non-zero constant k such that xy = k or y = kx (x≠0,y≠0), then y varies inversely with x.

We have given that,

x varies inversely with y and we need to find x when y = 4 when x = 132

X varies inversely with y there exist a constant of proportionality say k such that :

=> (x)(y) = k ----(1)

Put the value of x and y in equation (1) to find the value of k

=> (132)(4) = k

Therefore, k = 528 , We get

=> (x)(y) = 528

Now, we find x when y = 32, so plug the value of y in equation (1)

=> (x)(32) = 528

=> x = 528/32

=> x = 16.5

Hence, the value of x is 16.5 when y = 32 .

What is a rotation?

Rotation is when we rotate a figure to a certain degree. In a rotation, points and figures are turned on a coordinate plane. Majorly, rotations are about to the origin. Rotating a point about the origin can be, imagine a line connecting the origin to a point, and then rotate the line clockwise by the correct angle of rotation.

What is a dilation?

Dilation is a process of transformation in which something can be made larger or smaller. In a dilation, a point, a set of points can be expanded or contracted in relation to the origin. In expansion, the points in a figure move far away from the origin, and the side lengths of the figure increase. In a contraction, the points of the figure move closer to the origin, and the side lengths in the figure tend to reduce.

Answer:

68, 68, 44

x = 68

x - 24 = 44

Step-by-step explanation:

If you have a shape with three interior angles, it is a triangle. The three angles in a triangle add up to 180. Use this idea to write and solve an equation.

x + (x - 24) + 68 = 180

Combine like terms.

2x + 44 = 180

Subtract 44.

2x = 136

Divide by 2.

x = 68

So we can find x - 24

68 - 24 is 44.

The three angles are 68 (given), 68 (because x = 68), and 44 (because x-24)

The angles are 68, 68, and 44

substitute y = 4000/[tex]h^{2}[/tex]

SA =  [tex]h^{2}[/tex]  + 4x(4000/ [tex]h^{2}[/tex] )

SA =  [tex]h^{2}[/tex]  + 16000/h

Taking the derivative:

SA' = 2h - 16000/ [tex]h^{2}[/tex]
