2cos² 34° - 1 expressed as a single trigonometric ratio? (With explanation of steps please)
Answer:
Cos 68
Step-by-step explanation:
Given the expression 2cos² 34° - 1, we are to expression as a single trig ratio.
Let the angle be theta
Recall that sin²theta + cos²theta = 1
sin²theta = 1 - cos²theta ... 1
also Cos 2theta = Cos²theta - sin²theta ... 2
Substitute 1 into 2
Cos 2theta = Cos²theta - (1-cos²theta)
Cos 2theta = Cos²theta - 1 + cos²theta
Cos 2theta = 2Cos²theta - 1
Replace theta with 34
Cos 2(34)= 2Cos²(34)- 1
Cos 68 = 2Cos²(34)- 1
Hence the single trig expression is Cos 68

Question 6 is 70
Question 7 is 115
Step-by-step explanation: For these ones you want to subtract from 180 by the number it gives you. For an example If m<2=13 and find m<4 it would be like this 180-13=167.
In triangle NOP p equals 600 inches angle P equals 96° and angle N equals 64° what is the area of triangle NOP to the nearest 10th of a square inch?
9514 1404 393
Answer:
55,637.8 square inches
Step-by-step explanation:
We can find side n using the Law of Sines:
n/sin(N) = p/sin(P)
n = p(sin(N)/sin(P)) = 600·sin(64°)/sin(96°)
n ≈ 542.246913 . . . . inches
The angle O is ...
O = 180° -N -P = 180° -64° -96° = 20°
Then the area is ...
A = 1/2·np·sin(O)
A = (1/2)(542.246913 in)(600 in)·sin(20°) ≈ 55,637.81008 in²
The area of ∆NOP is about 55,637.8 in².
Answer:Area

Write the slope-intercept form of the line that travels through (4,-1) and is parallel to y = 1/4x
Answer:
y = 1/4x - 2
Step-by-step explanation:
If two lines are parallel to each other, they have the same slope.
The first line is y = 1/4x. Its slope is 1/4. A line parallel to this one will also have a slope of 1/4.
Plug this value (1/4) into your standard point-slope equation of y = mx + b.
y = 1/4x + b
To find b, we want to plug in a value that we know is on this line: in this case, it is (4, -1). Plug in the x and y values into the x and y of the standard equation.
-1 = 1/4(4) + b
To find b, multiply the slope and the input of x (4)
-1 = 1 + b
Now, subtract 1 from both sides to isolate b.
-2 = b
Plug this into your standard equation.
y = 1/4x - 2
This equation is parallel to your given equation (y = 1/4x) and contains point (4, -1)
Hope this helps!

If the 12-sided solid is rolled 180 times, how many times would you expect either number a 3, 9 or 11 to be rolled?
The probability that the 12-sided solid gets 3 , 9 or 11 is P ( A ) = 1/4 and the expected number of times is n = 45
What is Probability?The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible
Probability = number of desirable outcomes / total number of possible outcomes
The value of probability lies between 0 and 1
Given data ,
Let the probability that the the 12-sided solid gets 3 , 9 or 11 be P ( A )
Now , the value of P ( A ) is
Let the number of outcomes when rolling a 12-sided solid = 12
The number of times the solid is rolled = 180 times
So , the total number of outcomes = 12 x 180 = 2160
And , the probability of getting a 3 = 1/12
The probability of getting a 9 = 1/12
The probability of getting a 11 = 1/12
So , the total probability of getting a 3 , 9 or 11 = 3/12 = 1/4
The total expected number of times = 45
Hence , the probability is 1/6

Answer:
x = 99°
Step-by-step explanation:
first: find the supplement to 123°:
180 - 123 = 57°
second: since all triangle interior angles total a80°:
180 - 42 - 57 = 81°
third: x = the supplement to 81°, so, x = 180 - 81 = 99°
