In a unit circle, ø= 90°. Identify the terminal point and sin Ø.
A. Terminal point: (0,1); sin ø= 1
B. Terminal point: (1,0); sin ø=0 C. Terminal point: (1, 0); sin ø=1
D. Terminal point: (0,1); sin ø=0
Answer:
Terminal point: (0, 1); sinФ = 1 ⇒ A
Step-by-step explanation:
In the unit circle, Ф is the angle between the terminal side and the positive part of the x-xis.
The terminal point on the positive part of the x-axis is (1, 0),which means Ф = 0° or 360° and cosФ = 1, sinФ = 0The terminal point on the positive part of the y-axis is (0, 1),which means Ф = 90° and cosФ = 0, sinФ = 1The terminal point on the negative part of the x-axis is (-1, 0),which means Ф = 180° and cosФ = -1, sinФ = 0The terminal point on the negative part of the y-axis is (0, -1),which means Ф = 270° and cosФ = 0, sinФ = -1In a unit circle
∵ Ф = 90°
→ By using the 2nd rule above
∴ The terminal point is (0, 1)
∴ sinФ = 1
∴ Terminal point: (0, 1); sinФ = 1

Solve the triangle with the law of sines
Answer:
see below
Step-by-step explanation:
We can use the law of sines
sin 80 sin B
--------------- = -------------
31 14
Using cross products
14 sin 80 = 31 sin B
14/31 sin 80 = sin B
.984807753 = sin B
Taking the inverse sin of each side
sin ^ -1 ( .444751888) = B
26.41 = B
The sum of the angles of a triangle is 180
A+B+C = 180
80 + 26.41 + C =180
106.41 + C = 180
C = 73.59
We can use the law of sines to find c
sin 80 sin 73.59
--------------- = -------------
31 c
c sin 80 = 31 sin 73.59
c = 31 sin 73.59 / sin 80
c = 30.20
AB = 30.20

Add (16n2 + n + 1) + (4n2 - 5n - 2).
Answer:
20n2-4n-1
Step-by-step explanation:
You combine like terms, so you add 16n2 with 4n2 to get 20n2. Then you add n with -5n to get -4n. Finally, you add 1 with -2 to get -1.

Find four consecutive negative integers whose sum is -42
Answer:
-12, -11, -10 and -9 add up to -42
Step-by-step explanation:
We can solve this by expressing all four of those integers relative to the first one:
[tex]x + (x + 1) + (x + 2) + (x + 3) = -42\\4x + 6 = -42\\4x = -48\\x = -12[/tex]
so we know that the lowest one is -12, and the other three are sequentially higher value:
-12, -11, -10 and -9
Answer: -12, -11, -10, -9
Step-by-step explanation:
they all add up to -42

How to divide 7 divided by 7/4
Answer:
4
Step-by-step explanation:
7÷7/4
in these cases we multiply by the reciprocal
7× 4/7
7 and 7 can be cancelled with each other
the remaing answer = 4
Answer:
1/4
Step-by-step explanation:
First, since the numerator is 7 you want to see how many times you can divide that.
So, you can only divide 7 by 7 1 time so that turns into 1.
Hence, your numerator is now 1 and denominator stays the same so its..
1/4
