Answer:

(2pi)/5

Step-by-step explanation:

The cosine function cos(x) has a period of 2*pi.

If we change the argument of the cosine, the new argument will have a period of 2*pi. If the new argument is 5x, we have that the period will be:

5x = 2*pi

x = 2*pi/5

The period of this function will be (2pi)/5, because for every (2pi)/5 change in the value of x, the function will have the same value. The value of 5 multiplying the cosine does not interfere in the period.

Answer:

(3,2)

Step-by-step explanation:

A: (3,2)

Since A lies on the mirror line, it will mapped onto itself

A': (3,2)

The required coordinate of image A' is given as (3, 2). Option B is correct.

Coordinate, is represented as the values on the x-axis and y-axis of the graph. while the coordinate x is called abscissa and the coordinate of the y is called ordinate.

Here,

The Coordinate of A is (3, 2) and the equation of a line is x = 3, since
Point A lies on line x = 3, so the image of the point overlapped the original point. Although the coordinate of the image A' is given as (3, 2)

Thus, the required coordinate of image A' is given as (3, 2). Option B is correct.

Answer:

25

Step-by-step explanation:

The distance between the two points A and C is 25 units.

A coordinate plane is a 2D plane created by the junction of the x-axis and y-axis, two perpendicular lines. A coordinate system in geometry is a way to use one or more integers or coordinates to determine the positions of the points.

Given points are (5, 20) and (25,5). The distance between the points will be calculated as below:-

D = √ [ ( y₂ - y₁ )² + ( x₂ - x₁ )² ]

D = √ [ ( 25 - 5 )² + ( 20 - 5)² ]

D = √ ( 400 + 225 )

D = 25 units

Therefore, the distance between points A and C is 25 units.

Answer:

So when two lines intersect, it creates 4 angles. The angles that lie opposite to each other are congruent

If you know the measure of one angle in a linear pair, you can find the measure of the other because the sum of the measure of the two angles is 180 degrees. If you know the measure of one angle in a pair of vertical angles, you can find the measure of the other because they are congruent.

The height of the skyscraper is 34.4m

Step-by-step explanation:

Let the height of the skyscraper be 'h'

Distance between the skyscraper and the car = 62 m

Angle of depression = 29°

Angle = 61°

tan 61° = 62/h

1.80 = 62/h

h = 62/1.80

h = 34.4m

The height of the skyscraper is 34.4m

Answer:

x = 50

Step-by-step explanation:

[tex] m\angle ACB = m\overset {\frown} {AB} \\

\therefore m\angle ACB = 110°\\

\therefore m (reflex\angle ACB) = 360°- 110°\\

\therefore m (reflex\angle ACB) = 250°\\

Now \\

m\overset {\frown} {ADB}= m (reflex\angle ACB) \\

\therefore (4x + 50)°= 250°\\

\purple {\boxed {\bold {\therefore 4x + 50= 250}}} \\

(which\: is \: required\: equation) \\

\therefore 4x = 250-50\\

\therefore 4x = 200\\

\therefore x = \frac{200}{4}\\

\huge \red {\boxed {\therefore x = 50}} \\[/tex]

A) The equation needed to solve for x is [tex]4x + 50 = 250[/tex]. B) The value of x in the diagram is 50.

To solve the problem, we need to understand the relationships between the different parts of the circle and the given information.

Given:

[tex]\( \text{Measure of major arc ADB} = 4x + 50 \)[/tex]

[tex]\( \text{Measure of minor arc AB} = 110^\circ \)[/tex]

The total degrees in a circle = [tex]\( 360^\circ \)[/tex]

A) Type the equation needed to solve for x:

Since the sum of the measures of the minor arc AB and the major arc ADB must equal [tex]\( 360^\circ \)[/tex]:

[tex]\[\text{Measure of minor arc AB} + \text{Measure of major arc ADB} = 360^\circ\][/tex]

[tex]\[110^\circ + (4x + 50) = 360^\circ\][/tex]

[tex]4x + 50 = 250[/tex]

B) Solve for x:

First, set up the equation:

[tex]\[110 + 4x + 50 = 360\][/tex]

Combine the constant terms on the left side:

[tex]\[160 + 4x = 360\][/tex]

[tex]\[4x = 200\][/tex]

Divide both sides by 4:

[tex]\[x = 50\][/tex]

The complete question is:

In circle C major arc ADB is represented by 4x + 50.

A) Type the equation needed to solve for x.

B) What is the value of x in the diagram?

Answer:

3 hours and 16 minutes or 3.16 for Frank to finish the race

Step-by-step explanation:

60 miles long Frank is going 19 miles an hour

60 divided by 19 3.157 rounded up 3.16

Using the distance and speed, we calculate the time it takes for Frank to complete the bike race. He averages a speed of 19 miles per hour for a 60-mile race, which means it will take him approximately 3.16 hours to finish.

This question is about solving a typical problem in math - specifically, calculating time with information on distance and speed. To figure out how long it would take Frank to finish the 60-mile bike race, we use the formula Time = Distance / Speed. Given that Frank averages a speed of 19 miles an hour, we divide the total distance (60 miles) by his average speed (19 mph).

So, 60/19 ≈ 3.16. That means Frank will take approximately 3.16 hour to complete the bike race.

If the last day was 58 and all the other days were the same.

Let x be her pulse on the other days,

Then,

[tex]Average, 62=\dfrac{58+4x}{5}\\\text{Cross Multiply}\\58+4x=62 X 5\\\text{Suntract 58 from both sides}\\4x=(62X5)-58\\4x=310-58\\4x=252\\\text{Divide both sides by 4}\\x=63[/tex]

Her pulse on all the other days is 63.

Answer:

2

Step-by-step explanation:

You can think of logarithms as a rewritten exponent.

So exponents are in the form of a^b=c

Logarithms are [tex]log_a c=b[/tex]

Here, we have [tex]log_{5} 25[/tex]

Basically we have to figure out 5 to the power of what is 25.

So our answer is 2.

5^2=25

The value of log5 25 is 2, as 5 to the power of 2 equals 25.

The value of log₅ 25 is determined by asking the question: 'to what power do we need to raise 5 to get 25"

Since 5 squared is 25 (5² = 25).

The power of 5 is 2.

Therefore, log₅ 25 = 2
