If tan(x)=3/5 and sin(x)>0, what is sin(2x)?

With STEPS PLEASE AND NO TROLLING.

Answer:

A,D,E

Step-by-step explanation:

Answer:

A) The line goes up when moving right to left

False. The slope being zero means there is no change in elevation or height. The line is completely flat and horizontal. Recall that slope = rise/run. If the slope is 0, then the rise must be 0.  

B) The line goes down when moving right to left.

False. The same reasoning as choice A

C) The line is horizontal

True. Any line with a slope of zero is going to be horizontal. For instance, the equation y = 0x+5 is the horizontal line through 5 on the y axis.  

D) The line is vertical

False. This contradicts choice C above. Vertical lines have undefined slopes which aren't numbers due to the fact we cannot divide by zero.  

E) The run is zero

False. The run can be any number but zero. For example, slope = 0 = 0/1 or 0 = 0/5. Dividing zero over any nonzero number leads to 0.

F) The rise is zero

True. As mentioned before in previous answer choices (see choice A in particular).  

===========================================

In summary, there are only two true statements and they are choice C and choice F. The other statements are false.

Answer:

He would have to do 13 rides.

Step-by-step explanation:

If he initially pays $7, which lets him pay only $1 for each ride, so when he spends $20, he would have done 13 rides.

There are 13 rides will Luka need to ride in order to spend $20.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Luka buys a special pass to a fair for $7 that allows him to go on every ride for $1 each.

Here, Luka need to ride in order to spend $20.

Let number of rides = x

So, We can formulate;

⇒ $7 + $1x = $20

⇒ 7 + x = 20

Solve for x as;

⇒ x = 20 - 7

⇒ x = 13

Answer:

Brooke runs the fastest.

Step-by-step explanation:

Brooke runs 13 feet per second.

Therefore, speed of Broke = 13 feet per sec.

Will runs 308 feet in 26 seconds.

Speed of Will = [tex]\frac{\text{Distance}}{\text{Time taken}}[/tex]

                       = [tex]\frac{308}{26}[/tex]

                       = 11.85 feet per second

Ron runs 1 mile in 551 seconds.

1 mile = 5280 feet

Speed of Ron = [tex]\frac{5280}{551}[/tex]

                       = 9.58 feet per second

Debbie runs 658 feet in 1 minute.

1 minute = 60 seconds

Speed of Debbie = [tex]\frac{658}{60}[/tex]

                             = 10.97 feet per seconds

Here, speed of Brooke is the maximum.

Therefore, Brooke runs the fastest.

Answer:

62°

Step-by-step explanation:

Given that the triangle has two angle measures of 41° and 77°.

All the angles in a triangle must add up to 180° (e.g. 20° + 60° + 100°). So we write a simple equation to solve for the mystery angle measure:

Let x = the missing measure

[tex]41 + 77 + x = 180[/tex]

Now that we have our equation, let's start solving it. First, we need to add 41 and 77 together which simplifies the equation: [tex]118 + x = 180[/tex]

Then we subtract 118 from both sides to isolate x - this will give us the value of this variable: [tex]x = 62[/tex]

Therefore, the third angle must have a measure of 62°.

Answer:

y - 1 = -3/2(x - 0)

Step-by-step explanation:

trust me

The equation of the line in point-slope form is y - 1 = -3/2(x - 0).

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given that line that passes through the (0,1) and has a slope of -3/2. The equation of the line will be written as,

y - y₁ = m(x-x₁)

y - 1 = (-3 / 2) ( x - 0 )

Therefore, the equation of the line in point-slope form is y - 1 = -3/2(x - 0).

Answer:

Population of bacteria in culture after 14 hours is 285541.

Step-by-step explanation:

We are given with [tex]P_{t} =P_{0}(2)^{\frac{d}{t}}[/tex]

Here initial population is 41000 , t=5 and d=14

Plug in these values into the formula

[tex]P_{14} =41000(2)^{\frac{14}{5} }[/tex]

Simplify

[tex]P_{14}= 41000(2)^{2.8}[/tex]

     =41000(6.9644)

     =285540.5847...

To the nearest whole number is 285541.

Answer:

285541.

Step-by-step explanation:

P0=41000-The initial population

t=14-Time elapsed

d=5-The doubling time

Pt=P0⋅2^t/d

Pt=41000⋅2^14/5-Plug in

Pt=285540.5848≈285541-(Use parenthesis in the calculator for the exponent)

Answer: First you need to find the first point on the coordinate graph..which would be x then y. Remember run before you jump.

Step-by-step explanation:

The first point on the coordinate graph, x, must be identified first. Remember to run before you jump.

A set of variables that accurately depicts a position. On a graph, the first number represents the distance along, and the second number represents the distance up or down. For example, the point (12,5) is 12 units down and 5 units up.

A coordinate plane is an organizing structure for graphing and describing lines and points. The coordinate plane is made up of a vertical (y) axis and a horizontal (x) axis. The coordinate plane is divided into four quadrants. The origin is where these lines intersect (0, 0).

A pair of numbers that use the horizontal and vertical separations from the two reference axes to define a point's location on a coordinate plane. typically expressed by the x-value and y-value pair (x, y).
