If my initial angle is 30 degrees, what is the negative coterminal angle?
Answer:
Step-by-step explanation:
Coterminal angles are angles in standard position (angles with the initial side on the positive x -axis) that have a common terminal side. For example 30° , −330° and 390° are all coterminal.
Answer:
-330°Step-by-step explanation:
Coterminal angles have a difference of 360° or multiples of 360°.
Negative coterminal angle with 30° is:
30° - 360° = -330°HELP PLEASE ⚠️⚠️⚠️⚠️⚠️⚠️⚠️❗❗❗❗❓❓❓

Please help me i cant figure it out im stuck
what goes in the question mark box?
Answer:
y = 4x - 31
Step-by-step explanation:
Parallel slope (m) = 4
(5, -11)
y - y1 = m(x - x1)
y + 11 = 4(x - 5)
y + 11 = 4x - 20
y = 4x - 31

Answer: x is 36 degrees
Step-by-step explanation:
To solve this triangle, we can use sin -1 x = 14 / 24. This gives us 35.69 degrees, but in your answer choices you only get integers. We can round this up to 36 degrees to get the answer.
Answer:
36°
Step-by-step explanation:
sinx=14/24
x=[tex]sin^{-1} (\frac{14}{24})[/tex]
x=35.68533471° or 36°

Consider the two points (1, 6) and (4, 48).
a. Is there a line that goes through these two points? How do you know? If there is one, what is the equation of the line going through these
Answer:
Yes there is a line
y=14x-8
Step-by-step explanation:
use slope formula and incorporate the slope into the coordinates
Answer:
[tex]y = 14x - 8[/tex]
Step-by-step explanation:
. Using euclid postulate,
" any two points can be on a line".
So yes a line can be formed
Use the linear equation in ppont-slope form
[tex]y = mx + b[/tex]
where m is slope, b is the y intercept.
We can find the slope of the points first.
[tex]48 - 6 = 42[/tex]
[tex]4 - 1 = 3[/tex]
[tex] \frac{42}{3} = 14[/tex]
Our slope is 14.
We can plug in any two coordinates to find b.
[tex]14(1) - b = 6[/tex]
[tex] - b = - 8[/tex]
So our equation is
[tex]y = 14x - 8[/tex]
Which mapping diagram represents a function ? Would it be D?
Answer:
D
Step-by-step explanation:
Mathematically , for us to have a function, no 2 y values must have a single x value
Although, 2 x-values can have a single y value
The y values called the output values are listed on the right
The x values called the input values are listed on the left
So out of the options, with the given definition above, the one that represents a function is the option D

The world famous gambler from Philadelphia, Senor Rick, proposes the following game of chance. You roll a fair die. If you roll a 1, then Senor Rick pays you $25. If you roll a 2, Senor Rick pays you $5. If you roll a 3, you win nothing. If you roll a 4 or 5, you must pay Senor Rick $10, and if you roll a 6, you must pay Senor Rick $15. Is Senor Rick loco for proposing such a game? Explain.
Answer:
You lose $0.833 while Rick gains $0.833, and so Rick is not Loco
Step-by-step explanation:
There are six numbers on a dice. Thus, probability of rolling exactly one number = 1/6
Probability of rolling two is 2/6.
Rolling a 1 pays $25, and probability = 1/6
Rolling a 2 pays $5,and probability = 1/6
Rolling a 3 pays $0, and probability = 1/6
Rolling a 4 or 5 pays -$10, and probability = 2/6
Rolling a 6 pays -$15, and probability = 1/6
Thus,lets calculate the expected value;
EV = (25 × 1/6) + (5 × 1/6) + (0 × 1/6) + (-10 × 2/6) + (-15 × 1/6)
EV = - $0.833
This means you lose $0.833 while Rick gains $0.833, and so Rick is not Loco.
