Answer:

53.1°

Step-by-step explanation:

Look at the right triangle formed. You are given the Hypotenuse and an adjacent side to the angle needed to calculate the measure of the arc.

To find measure of angle use Cosine

Once you find measure of angle (central angle), you'll have the measure of the arc because they are the same.

cos -1 (9/15)  = 53.13

Answer:

to solve for k we will put y=6

The Highest Common Factor (HCF) of 18, 36 and 120 is 6.

A factor is a number that divides another number, leaving no remainder.

Given that, we need to find HCF of 18, 36 and 120.

Finding Factors :-

18 = 2 × 3 × 3

36 = 2 × 2 × 3 × 3

120 = 2 × 2 × 2 × 3 × 5

Common factors = 2 and 3

Therefore,

Highest Common Factor = 2 × 3 = 6

Hence, the Highest Common Factor (HCF) of 18, 36 and 120 is 6.

Answer:

(9, - 9 )

Step-by-step explanation:

P (2, 3 ) → P' (5, - 4 )

2 → 5 in the x- direction is + 3

3 → - 4 in the y- direction is - 7

translation rule is then (x, y ) → (x + 3, y - 7 ) , so

(6, - 2 ) → (6 + 3, - 2 - 7 ) → (9, - 9 )

Step-by-step explanation:

The absolute value parent function, f(x) = | x |, is defined as:

[tex]f(x)=\begin{cases}x \; &\text{if}\;x > 0\\0 \; &\text{if} \; x=0\\-x\; &\text{if}\;x < 0\end{cases}[/tex]

Therefore:

Its graph is V-shaped and has the following properties:

Given absolute value expression:

[tex]|3x+12|[/tex]

Simplify the given expression:

[tex]\implies |3x+12|=|3(x+4)|=3|x+4|[/tex]

Set the simplified absolute value expression to zero and solve for x:

[tex]\begin{aligned}\implies 3|x+4|&=0\\|x+4|&=0\\x+4&=0\\x&=-4\end{aligned}[/tex]

Therefore, the vertex of the graph of the given absolute expression is (-4, 0).

Therefore, the slope of the expression will be positive for values of x greater than -4, and negative for values of x less than -4.  Set the expression inside the absolute value sign to positive and negative to find the two expressions with positive and negative slopes:

[tex]|3x+12|=\begin{cases}3x+12 \; &\text{if}\;x > -4\\0 \; &\text{if} \; x=-4\\-3x-12\; &\text{if}\;x < -4\end{cases}[/tex]

Given absolute value expression:

[tex]|(x-19)+11|[/tex]

Simplify the given expression:

[tex]|(x-19)+11|=|x-19+11|=|x-8|[/tex]

Set the simplified absolute value expression to zero and solve for x:

[tex]\begin{aligned}\implies |x-8|&=0\\x-8&=0\\x&=8\end{aligned}[/tex]

Therefore, the vertex of the graph of the given absolute expression is (-8, 0).

Therefore, the slope of the expression will be positive for values of x greater than 8, and negative for values of x less than 8. Set the expression inside the absolute value sign to positive and negative to find the two expressions with positive and negative slopes:

[tex]|(x-19)+11|=\begin{cases}x-8\; &\text{if}\;x > 8\\0 \; &\text{if} \; x=8\\8-x \; &\text{if}\;x < 8\end{cases}[/tex]

Given absolute value expression:

[tex]|14-(x-6)|[/tex]

Simplify the given expression:

[tex]|14-(x-6)|=|14-x+6|=|20-x|[/tex]

Set the simplified absolute value expression to zero and solve for x:

[tex]\begin{aligned}\implies |20-x|&=0\\20-x&=0\\x&=20\end{aligned}[/tex]

Therefore, the vertex of the graph of the given absolute expression is (20, 0).

Therefore, the slope of expression will be positive for values of x greater than 20, and negative for values of x less than 20. Set the expression inside the absolute value sign to negative and positive to find the two expressions with positive and negative slopes:

[tex]|14-(x-6)|=\begin{cases}x-20 \; &\text{if}\;x > 20\\0 \; &\text{if} \; x=20\\20-x \; &\text{if}\;x < 20\end{cases}[/tex]

Given absolute value expression:

[tex]|14-(6-x)|[/tex]

Simplify the given expression:

[tex]|14-(6-x)|=|14-6+x|=|x+8|[/tex]

Set the simplified absolute value expression to zero and solve for x:

[tex]\begin{aligned}\implies |x+8|&=0\\x+8&=0\\x&=-8\end{aligned}[/tex]

Therefore, the vertex of the graph of the given absolute expression is (-8, 0).

Therefore, the slope of expression will be positive for values of x greater than -8, and negative for values of x less than -8.  Set the expression inside the absolute value sign to positive and negative to find the two expressions with positive and negative slopes:

[tex]|14-(6-x)|=\begin{cases}x+8 \; &\text{if}\;x > -8\\0 \; &\text{if} \; x=-8\\-x-8 \; &\text{if}\;x < -8\end{cases}[/tex]

Answer:

Step-by-step explanation:

The whole number obtained as the result of the ratio (10²⁰⁰⁰⁰+10²⁰⁰²) : (10²⁰⁰¹+10²⁰⁰¹) is 5.

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers. Comparing two numbers by dividing them is how ratios work. Your formula would be A/B if you were contrasting one data point (A) with another data point (B).

It is given that the ratio is,

(10²⁰⁰⁰⁰+10²⁰⁰²) : (10²⁰⁰¹+10²⁰⁰¹)

We have to apply the arithmetic operation for the given ratio in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

[tex]=\frac{10^{2000}+10^{2002}}{10^{2001}+10^{2001}} \\\\ =\frac{10^{2000}(1+100)}{10^{2000}(10+10)} \\\\ =\frac{101}{20} \\\\=5[/tex]

Thus, the whole number obtained as the result of the ratio (10²⁰⁰⁰⁰+10²⁰⁰²) : (10²⁰⁰¹+10²⁰⁰¹) is 5.

Step-by-step explanation:

remember the definitions of these 2 types of numbers ?

rational numbers are all numbers that can be written as

a/b

where a and b are integers, and b <> 0.

this includes all real fractions, but also all whole or integer numbers, as they can be written as a/1.

if they have digits after the decimal point, they are either finite, or they have a repeating pattern for all eternity.

irrational numbers are all numbers with an infinite series of digits after the decimal point without any repeating patterns.

that includes all squares roots of non-squared numbers or any other roots of numbers that are not the product of correspondingly many multiplications with themselves. and trigonometric function and logarithm results, and the special numbers in math and physics : pi and e.

so,

4/7 is rational

sqrt(30) is irrational

21/sqrt(4) is a trick question, as sqrt(4) = 2.

so, this is actually

Answer:

11.8° and 78.2°

Step-by-step explanation:

let the angles be x and x + 66.4

complementary angles sum to 90° , then

x + x + 66.4 = 90

2x + 66.4 = 90 ( subtract 66.4 from both sides )

2x = 23.6 ( divide both sides by 2 )

x = 11.8 and

x + 66.4 = 11.8 + 66.4 = 78.2

The 2 angles are 11.8° and 78.2°
