Answer:
p/√(1-p^2)
Step-by-step explanation:
Firstly we can write our sin (θ) = p/1
Mathematically, the sine of an angle refers to the ratio of the opposite to that of the hypotenuse. Hence we can say that p is the opposite while 1 is the hypotenuse of the right-angled triangle.
Now to get the third side of the right angled triangle, we use the pythagoras’ theorem. This states that the square of the hypotenuse equals the addition of the squares of the other two sides of the right angled triangle. Thus, mathematically:
1^2 = p^2 + adjacent^2
Adjacent^2 = 1 - p^2
Adjacent = √(1-p^2)
The tan of an angle refers to the ratio of the opposite to the adjacent.
Thus, our tan here will be p/√(1-p^2)
Tan θ = p/√(1-p^2)
Answer:
3)p/(√ 1-p^2)
Step-by-step explanation:
In trigonometry, the three fundamental or basic functions are represented by the notation SOH CAH TOA where
SOH
Sin θ = opposite/hypotenuse
Cos θ = Adjacent / hypotenuse
Tan θ = Opposite / Adjacent
And from Pythagoras theorem,
Opposite ² + Adjacent ² = Hypotenuse²
Hence if Sin θ = p/1, the opposite side is p, the hypotenuse side is 1 then
the adjacent side from the equation above
Adjacent side² = 1 - p²
Adjacent side = √(1 - p²)
Tan θ = p/√(1 - p²)
Using the distributive law, work out

The correct question is;
You spin the spinner, flip a coin, then spin the spinner again. Find the probability of the compound event. Write your answer as a fraction or percent. If necessary round your answer to the nearest hundredth. Find the probability of spinning an odd number, flipping heads, then spinning another odd number? Write your answer as a fraction in simplest form.
Answer:
If the spinner has an even number of spaces, the probability of spinning an odd number, flipping heads, then spinning a yellow is = 1/8
Whereas, if the spinner has an odd number of spaces, more information is needed
Step-by-step explanation:
The answer will depend on whether the spinner has an odd or even number of spaces.
Now, if we suppose that the spinner has an even amount of numbers on it, there will be an equal number of odd and even numbers.
Thus the probability of spinning an odd number is ½.
Also, the probability of flipping heads on a coin is ½.
Thus, the probability of spinning an odd number, flipping heads, then spinning another odd number is;
= ½ × ½ × ½ = ⅛
Similarly,
If the spinner has an odd amount of numbers on it, the probability of spinning an odd number will vary. For instance, if there are 5 spaces on the spinner, the probability of spinning an odd number will be
3
However, if there are 9 spaces, the probability will be 5/9
So,we can conclude that;
If the spinner has an even number of spaces, the probability of spinning an odd number, flipping heads, then spinning a yellow is = 1/8
Whereas, if the spinner has an odd number of spaces, more information is needed.

. If they set up their camera 322 meters from the base of the mountain and the mountain is 597 meters high, what angle should he point his camera from the horizantal.
Answer:
the angle required for them to point their camera to the horizontal should be at 61.66°
Step-by-step explanation:
Given that the base of the camera is 322 meters from the horizontal and the height is 597 meters.
We can use the tangent of the trigonometric equation.
tan θ = opposite / adjacent
tan θ = 597/322
tan θ = 1.854
θ = tan⁻¹ (1.854)
θ = 61.66°
Hence, the angle required for them to point their camera to the horizontal should be at 61.66°
Answer:
Step-by-step explanation:
The position of the camera forms a right angle triangle. The horizontal distance from the base of the mountain represents the opposite side of the triangle while the height of the mountain represents the adjacent side of the triangle. To determine the angle, # that he should point his camera from the horizontal, we would apply the tangent trigonometric ratio which is expressed as
Tan # = opposite side/adjacent side
Tan# = 597/322 = 1.85
# = Tan^-1(1.85)
# = 61.61°

how to get the answer ?
Answer:
c
Step-by-step explanation:
it has to be a negative graph so a and d aren't right and the y intercept is 3 so c is right
Answer:
the answer is C
Step-by-step explanation:
1st step to write the slope intercept form then first u need to find the two points that ur going to use, then u get the slope
FIND THE SLOPE:
point 1: (2,0)
point 2: (0,3)
slope= y2-y1/x2-x1
s= 3-0/0-2
s= -3/2
2nd step is to find the y-intercept, to find that u take the slope intercept form which is y=mx+b
m=slope
b=y-intercept
and now substitute the variable for the known value
pick any of the two points, so u can substitute the variable X and Y
x=2
y=0
b=-3/2
0=2(-3/2)+b
solve to find B
distribute 2
2(-3/2)=-6/2 or -3
0=-3+b
and now add 3 to both sides
0+3=-3+3+b
b=3
now the slope intercept formula is y=-3/2x+3
to check the answer u can substitute the X and Y of one of the points and see if u get the solution as 0 or 3 (it depends on which point u chose)

Find the equation of the line parallel to 2y-3x= 4 and passing through the point (6,7)
Answer:
We have equation of a line:
2y - 3x = 4 => y = (3/2)x + 4
The equation of the line that is parallel to above line and passes through the point (6, 7) would have form y = ax + b, and
a = 3/2
6a + b = 7
=> b = 7 - 6a = 7 - 6 x 3/2 = 7 - 9 = -2
=> The equation of that line: y = (3/2)x - 2

Describe when you would need to solve a system of linear equations, instead of a single linear equation
Answer:
See explanation below
Step-by-step explanation:
A system of linear equations is a system that is formed when you have two or more variables, for example:
[tex]x=2y+z\\3y-4x=7y+2z\\2y+z=4x+3y[/tex]
In this case, we have 3 equations with 3 variables in total (x, y and z). Thus, we would need to solve a system of linear equations (they are linear because none of the variables have exponents).
On the other side, a single linear equation has only one variable that we need to find, for example:
[tex]3x=\frac{5}{3}[/tex]
In this case we would just have to solve for x
[tex]3x=\frac{5}{3} \\9x=5\\x=\frac{5}{9}[/tex]
Thus, we need to solve a system of linear equations when we have more than one variable (and more than one equations) as opposed to when we have just one variable and a single equation (single linear equation)

A ball is thrown into the air with an upward velocity of 13 ft/s. Its height h in feet after t seconds is given by the function h = −2t^2+ 13t + 24. In how many seconds does the ball reach its maximum height?
Answer:
3.25 seconds
Step-by-step explanation:
The maximum height will occur when the velocity of the ball reaches zero in the air.
Velocity is given as the derivative of height, dh/dt.
The equation of height given is:
[tex]h = -2t^2+ 13t + 24[/tex]
Differentiating height, h, with respect to time, t, we have:
[tex]v = dh/dt = -4t + 13[/tex]
When v = 0:
[tex]0 = -4t + 13\\\\=> 4t = 13\\\\t = 13 / 4 = 3.25 secs[/tex]
Therefore, it will take 3.25 seconds for the ball to reach maximum height.

fathi has $1.10 in his printing account. each sheet of paper he uses reduces his printing account balance by $0.25. Fathi wants to print out a PDF document that is 47 pages long. To save paper, he decides to print on both sides of each sheet and to print two pages on each sides of the sheet.
Answer:
IF THE question is After Fathi prints, what will be the balance in his printing account?
then it is: $1.9
There are 47 pages.
Printing on both sides would divide the number of pages into half.
47/2 = 23.5
2 pages on each side would mean 4 pages on one sheet. Therefore, the number of pages will be further divided by 2.
23.5/2 = 11.75
There cannot be 11.75 pages so we will round it up to 12 pages.
Each page costs $0.25 so 12 pages will cost:
12 x 0.25 = $3
Faithi has $1.1 so new account balance will be:
1.1 - 3 = $-1.9
Therefore, Fathi's balance in his printing account would be negative $1.9.
Answer:
The answer is $-1.90
