a) A graph is drawn below.

Explain how you know that y is not directly proportional to x.

Answer:

x = 17°, m∠ A = 114°

Step-by-step explanation:

We can tell that these pair of angles are corresponding, provided;

Line 1 ║ Line 2, AB ∩ Line 1 and Line 2 ⇒ corresponding ∠s ≅,

m∠ A = m∠ B ⇒ Substitute values of A and B,

6x + 12 = 3x + 63 ⇒ Subtract 3x on either side,

3x + 12 = 63 ⇒ Subtract 12 on either side of equation,

3x = 51 ⇒ Divide either side by 3,

x = 17 ⇒ Substitute value of x to solve for m∠ A,

m∠ A = 6 * ( 17 ) + 12,

m∠ A = 102 + 12,

m∠ A = 114

Solution; x = 17°, m∠ A = 114°

Answer:

x = 17, ∠A = 114°

Step-by-step explanation:

I'm 8 years old and I know how to do this.

6x + 12 = 3x + 63

3x + 12 = 63

3x = 51

x = 17

6(17) + 12

102 + 12 = 114

Answer: The mean is the average of all the values. The median is the number that falls in the exact center of all the measurements, while the mode is the number that occurs most frequently. ... One way to measure variability, range, is the difference between the highest and lowest values in a data set.

There are 3 Answers:

Choice A) reflect the dilated circle over the horizontal line through point C.

Choice D) rotate the dilated circle 180 degrees around point C

Choice E) translate the dilated circle to center B

Due to symmetry, rotations and reflections do not change a circle. This is why we are able to rotate around point C so that it looks like a translation has occurred. A similar thing happens with reflections as well.

The correct Answers:

A) reflect the dilated circle over the horizontal line through point C.

D) rotate the dilated circle 180 degrees around point C

E) translate the dilated circle to center B

A transformation is a process that manipulates a polygon or other two-dimensional object on a plane or coordinate system.

Given is circle A is dilated so that it is the same size as circle B, we need to determine the transformations performed to show that the circles are similar.

We know that,

Due to symmetry, rotations and reflections do not change a circle.

So, rotate around point C so that it looks like a translation has occurred.

A similar thing happens with reflections as well.

Hence, the correct options are A, D and E

Answer:

18a) The height of tree is 6.34ft.

Diagram We would scale a right side triangle showing side; 6.34ft x base 13.59ft x 15cm slope.

b) 11.54 degree

Step-by-step explanation:

18a) sin(25) = 0.4226182617 is what you multiply to check the height.

15 x 0.4226182617 = 6.339273926   = 6.34ft.

Using the measurements of pythagoras you can scale each measurement above.  6.34 = (x0.5) = 3.17cm to draw the trees height.

15ft wire = scale the diagram draw  1cm = 2ft So that 7.5cm =  = 15ft

Draw a right angle triangle and before creating the slope use protractor or guess 25 degree at bottom of slope and label it.

This will make a 7.5cm slope and label it 15ft.

We also measure out the base which on scale cm per foot is 13.59 x 0.5 = 6.80cm and label it 13.59ft.

We find the base measurement by finding the square of each 15 and 6.34

c^2 - a^2 = b^2

a= 6.34 x 6.34 = 40.1863939089 = √40.19

c = 15 x 15 =  √225

c-b = √225 - √40.19 =  √184.81

side = b  

b^2 = √184.81= 13.5944841756 = 13.59ft

18 b)  To find an angle x  with given measurements 4ft base and 20ft slope we  

use sin( base/slope) = (run/rise)

So that 4/20 = 0.2  

Then plug in for sin -1  0.2 = 11.54 degree = (calc ..11.53695903)

Notes;

If 4ft base was not given and the height of wall was given we would do the same using base as run and slant as run run/rise  but we would substitute sin-1 and after division run/rise we would plug in the decimal to cos-1 (decimal).

Answer:

f(x+1)=(5/6)f(x)on:          Five-sixths Superscript f (x)

EXPLANATION:

The defining characteristic of a geometric sequence is that each term is a constant multiple of the previous term, called the common ratio denoted r in the rules for geometric equations.

625/750=750/900=etc=r=5/6

The function that can be used to model the graphed geometric sequence is f(x + 1) = 5/6 f(x).

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

The equation of a straight line can be also written as -

Ax + By + C = 0

By = - Ax - C

y = (- A/B)x - (C/A)

A geometric sequence is a sequence such that -

a(n + 1)/a(n) = K {constant}

[K] is called common ratio.

Given is a graph representing a geometric sequence.

Now, for -

f(2) = 1080

and

f(1) = 1296

So -

f(2)/f(1) = 1080/1296 = 5/6

In general -

f(x + 1)/f(x) = 5/6

f(x + 1) = 5/6 f(x)

Therefore, the function that can be used to model the graphed geometric sequence is f(x + 1) = 5/6 f(x).

135 gallons of water in the aquarium after 45 minutes of draining.

Arithmetic operations can also be specified by the addition, subtract, divide, and multiply built-in functions.

+ Addition operation: Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

Given that water is draining from an aquarium at a rate of 3 gallons per minute.

The total change in the amount of water in the aquarium after 45 minutes of draining is as:

⇒ 45×3

Apply the multiplication operation in the integers,

⇒ 135 gallons

Answer:

The volume of the cylinder would be 226.19in however if you need it in terms of pi it would be  V = 72 π in3

Step-by-step explanation:

V=πr2h=π·62·2≈226.19467, hope I was able to help you

And that is basically what you have to do

Answer:

72π inches^3

Step-by-step explanation:

The volume of a cylinder can be found using:

v=πr^2h

We know that the radius is 6 inches, and the height is 2 inches. So, we can substitute 6 in for r, and 2 in for h.

v= π 6^2 *2

Evaluate the exponent

v= π 36*2

Multiply 36 and 2

v= π72

So, the volume in terms of pi is:
