Which function is shown on the graph?

A. f(x)=1/2cos x

B. f(x)=1/2sin x

C. f(x)=-1/2cos x

D. f(x)=-1/2sin x

Answer:

True

Step-by-step explanation:

[tex]\frac{a^9}{a^4} = a^8 . \frac{a^1}{a^4}[/tex]

[tex]a^8 . a^1 = a^9[/tex]

[tex]\frac{a^9}{a^4} = \frac{a^9}{a^4}[/tex]

Answer:

Classify by angles: Equiangular

Classify by sides: Equilateral

Step-by-step explanation:

An equiangular triangle has angles that all measure 60 degrees. An equilateral triangle is a triangle that has sides will all of the same lengths. This triangle meets both of these requirements.

Hope it helps!

Answer:

x = 65

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

subtract the sum of the 2 given angles from 180° for third angle

third angle = 180° - (60 + 55)° = 180° - 115° = 65°

65° and x are vertical angles and are congruent, thus

x = 65

Answer:

x = 65 degrees

Step-by-step explanation:

Three angles are marked with their values:  55 and  60 degrees.  Thus, the third interior angle of the left triangle (unmarked) is 180 degrees - (115) degrees = 65 degrees.

This 65 degree angle and x are vertical angles.  Thus, x = 65 degrees.  This plus y form a straight angle, so y = 180 degrees - 65 degrees = 115 degrees.

Answer:

67.5 mile per hour

Step-by-step explanation:

Kevin can travel LaTeX: 22\frac{1}{2}\:22 1 2miles in LaTeX: \frac{1}{3}\:1 3hour. What is his average speed in miles per hour? Group of answer choices

Speed = Distance /Time

Speed = 22 1/2 miles ÷ 1/3 hour

= 45/2 ÷ 1/3

= 45/2 × 3/1

= 67.5 mile per hour

Answer:

Positive correlation exists ;

Number of Steps taken will cause heart rate to increase.

Step-by-step explanation:

Correlation refers to the relationship which exists which exists between two variables. It shows how an increase in one variable affects the other variable. Variables are divided into independent and dependent variables. Correlation may either be positive, negative or non - existent.

Given the correlation Coefficient of 0.88 between heart rate and number of steps taken, the R value being close to 1 depicts a strong positive relationship or correlation.

Correlation between number of steps taken and heart rate.

Yes, The number of steps taken will cause the hear rate to increase. Hence, the dependent variable is is heart rate and it depends on the number of steps taken (independent variable).

1. The number of steps taken is correlated with the hate rate because a correlation coefficient of 0.88, shows a positive strong relationship.

2. The her heart rate is dependent on the number of steps she takes, therefore, number of steps taken causes her rate rate to change.

1. The number of steps taken is correlated with the hate rate because a correlation coefficient of 0.88, shows a positive strong relationship.

Answer:

[tex]TU = 15[/tex]

Step-by-step explanation:

Given

[tex]\square MNOP \simeq\ \square STUV[/tex]

[tex]NO = 10[/tex]

[tex]OP = 4[/tex]

[tex]TU = x[/tex]

[tex]UV = 6[/tex]

Required

Determine the length of TU (i.e. x)

Because both shapes are similar, then the following equivalent ratios exist:

[tex]NO : OP = TU : UV[/tex]

Substitute values for NO, OP, TU and UV

[tex]10 : 4 = x : 6[/tex]

Represent as fraction

[tex]\frac{10 }{ 4 } = \frac{x }{ 6}[/tex]

Multiply both sides by 6

[tex]6 * \frac{10 }{ 4 } = \frac{x }{ 6} * 6[/tex]

[tex]6 * \frac{10 }{ 4 } = x[/tex]

[tex]x = 6 * \frac{10 }{ 4 }[/tex]

[tex]x = \frac{60 }{ 4 }[/tex]

[tex]x = 15[/tex]

Hence:

[tex]TU = 15[/tex]

Answer:

Hence, Suzanne is working at a faster rate.

Suzanne started with the most windows already installed

Step-by-step explanation:

Number of windows he's installing :

Tom's equation :

y = 7x + 2

Suzanne's equation :

y = 6x +5

x = number of days used

Let y = 10

Tom:

10 = 7x + 2

10 - 2 = 7x

8 = 7x

x = 8/7 ; x = 1.143

Suzanne :

y = 6x + 5

10 = 6x + 5

10 - 5 = 6x

5 = 6x

x = 5/6

x = 0.833

Since 0.833 < 1. 143

Hence, Suzanne is working at a faster rate.

Intercept in Suzanne's equation = 5

Intercept in Tom's equation = 5

Suzanne started with the most windows already installed

25.5125 = 25 + 5125 / 10⁴ = 25 + 41 / 80

(41 / 80) / 60⁻¹ = 2460 / 80 = 123 / 4 = 30.75

30.75 = 30 + 75 / 10² = 30 + 3 / 4

(3 / 4) / 60⁻² = 180 / 4 = 45

→   25.5125₁₀ = [25].[30][45]₆₀

Answer:

Domain: (-∞, ∞) or All Real Numbers

Range: (0, ∞)

Asymptote: y = 0

As x ⇒ -∞, f(x) ⇒ 0

As x ⇒ ∞, f(x) ⇒ ∞

Step-by-step explanation:

The domain is talking about the x values, so where is x defined on this graph? That would be from -∞ to ∞, since the graph goes infinitely in both directions.

The range is from 0 to ∞. This where all values of y are defined.

An asymptote is where the graph cannot cross a certain point/invisible line. A y = 0, this is the case because it is infinitely approaching zero, without actually crossing. At first, I thought that x = 2 would also be an asymptote, but it is not, since it is at more of an angle, and if you graphed it further, you could see that it passes through 2.

The last two questions are somewhat easy. It is basically combining the domain and range. However, I like to label the graph the picture attached to help even more.
