If cos 0 = 3/5
and angle 0 is in Quadrant IV, what is the value of tan 0 ?
Tan =
Answer:
-4/3.
Step-by-step explanation:
cos O = 3/5
Using Pythagoras to find the length of the side opposite the angle O:
As the cos of O is adjacent/ hypotenuse, Hypotenuse = 5 , adjacent side = 3 so
opposite side. = sqrt(5^2 - 3^2) = sqrt 16
= 4.
Now the tangent is negative in Q IV so
tan O = opposite / adjacent side = -4/3
find missing factor 7^-5 = blank × 7^6
Answer:
7^-11
Step-by-step explanation:
Given the expression 7^-5 = blank × 7^6
Let the blank be x
7^-5 = x × 7^6
x = 7^-5/7^6
According to law of indices a^b/a^c = a^b-c
x = 7^(-5-6)
x = 7^-11
Hence the missing factor is 7^-11

1. Which graph has the y-intercept -2?
2. Which statement describes the y-intercept of the graph of aproportional relationship?
A: It is equal to the x-intercept of the line.
B: It is greater than the x-intercept of the line.
C: The line intersects the y-axis of the graph at the origin.
D: The line intersects the y-axis of the graph above the origin.
Answer:
For 1 it is D
For 2 it is A
Hope this helps :)
Step-by-step explanation:
Answer:
#1
Option D
Y intercept-2 means line passes through the downward y-axis.#2
As
[tex]\\ \sf\longmapsto x\propto y[/tex]
It is equal to the x-intercept of the line.
Option A is correct
The points J, K, L and M all lie on the same line segment, in that order, such that the ratio of JK:KL:LMJK:KL:LM is equal to 1:4:4.1:4:4. If JM=45,JM=45, find JL.JL.
Answer: JL = 25
Step-by-step explanation: Segment JM is the total measure of the line segment and it equals 45.
Suppose first segment JK measures d.
The total ratio is the sum of each part
d + 4d + 4d = 9d
The sum of each part corresponds to the total measure of the line segment. Then:
9d = 45
d = 5
Segment JL is
JL = d + 4d
JL = 5d
JL = 5.5
JL = 25
Segment JL measures 25 units.

Step-by-step explanation:
HELP In △ABC, m∠A = 75° and m∠C = 20°, What is m∠B?
To solve this question, we must know the the angle sum property of a triangle. Therefore the value of ∠B is 85° when ∠A = 75° and ∠C=20° in △ABC
What is angle sum property of a triangle?According to angle sum property of a triangle, the sum of all angles of a triangle is always 180 degree. It can never be more than or less than 180 degree. If two angles of a triangle is given then the third angle can be calculated by subtracting the sum of two angle from 180°
The sum of the three angles in a triangle = 180° , that is
∠ A + ∠ B + ∠ C = 180°
Substituting the given values in the given equation we get
75° + ∠ B + 20° = 180°
∠ B + 95° = 180°
subtracting 95° from both sides we get
∠ B = 85°
Therefore the value of ∠B is 85° when ∠A = 75° and ∠C=20° in △ABC

24 is 3/4% of what number
Answer:
32
Step-by-step explanation:
Alright, so think of the "what number" as x in this case. (Or any number/symbol you choose.)
So our simple equation looks something like this:
[tex]24= x *\frac{3}{4}[/tex]
So, to find out what the "what number" would be we'd flip the fraction around/find the reciprocal and multiply 24 by it. That gives us "x" or the number we're missing.
So: [tex]24 * \frac{4}{3} = x[/tex]
Doing the simple math we get:
[tex]24 * \frac{4}{3} = 32[/tex].
32 is your answer.

is palpatine the strongest sith
Answer:
One may think that he is the most powerful Sith Lord, and on some levels this is correct, but that title falls to another, even more powerful Sith Lord. That is Jar Jar Binks. He possesses the power to wipe out entire universes without blinking an eye. Jar Jar is an entity that was here before the universe was created. He made God. He even made Shaggy in his image so that he could have a set of eyes on Earth. He needed a right hand man to corrupt humanity at its source. Some might say that Jar Jar is the true form of evil, but I refute that claim with an argument of my own. Jar Jar Binks may have destroyed countless lives, but he did so in order to keep the balance of the universe, and for that, I thank him. All hail Jar Jar.

Point A is located at (-2,-2). Plot all of the points 3 units away that have the same y-coordinate as point A.
Answer:
Points are ( 1, -2) , (-5, -2)
Step-by-step explanation:
the given point is A ( -2, -2)
If we fix the y coordinate , then we can change only x coordinate
As we want point 3 unit away
So, add 3 and subtract 3 from x coordinate to find the resultant point
If we add 3 to x coordinate , we get
-2 + 3 = 1
So the point be ( 1, -2)
If we subtract 3 to x coordinate , we get
-2 - 3 = -5
So the point be ( -5, -2)

Solve 18- m=6
Answer:
m = 12
Step-by-step explanation:
Given
18 - m = 6 ( subtract 18 from both sides )
- m = - 12 ( multiply both sides by - 1 )
m = 12
For which value of m is start fraction 4 over 16 end frction equals start fraction m over 24 end fraction a proportion? A. m = 6 B. m = 8 C. m = 12 D. m = 14
Answer:
A. M=6
Step-by-step explanation:
Basically, this question is asking you to find m if 4/16 = m/24.
First, 4/16 can be simplified to 1/4. This will make it easier to solve.
You now have 1/4 = m/24.
Multiply both sides by 24 to get 24/4 = m.
Simplify to get m = 6.
