How do you do this???
Given tan Ф = 4/5, find all other trig functions.
let : y = Opponent side, x= Adjecent side
and r= hypotenuse
tan = 4/5
y/x = 4/5 => y =4, x=5
so, r = √4²+5²=√16+25=√41
sin = y/r = 4/ √41
cos = x/r = 5/√41
tan = y/x = 4/5
csc = r/y = √41 /4
sec = r/x = √41 /5
cot = x/y = 5/4
What is the area of the blue sector?
I need help please
Answer:
3.3 units²
Step-by-step explanation:
Hi there!
[tex]\frac{Angle(sector)}{360} = \frac{Area (sector)}{Area (circle)}[/tex]
Angle of the sector: 15 degrees
Area of the sector: solving for
Area of the circle: ?
1) Determine the area of the circle
[tex]A=\pi r^2[/tex] where r is the radius
Plug in the radius (5)
[tex]A=\pi (5)^2\\A=25\pi[/tex]
Therefore, the area of the circle is 25π units².
2) Plug all information into sector formula
[tex]\frac{Angle(sector)}{360} = \frac{Area (sector)}{Area (circle)}\\\frac{15}{360} = \frac{Area (sector)}{25\pi }[/tex]
Multiply both sides by 25π
[tex]\frac{15}{360} *25\pi = Area(sector)\\\frac{15}{360} *25\pi = Area(sector)\\3.3=Area(sector)[/tex]
Therefore, the area of the sector is approximately 3.3 units².
I hope this helps!

Answer:
a) (x < -3) ∪ (-1 < x)
b) all real numbers
c) x ≤ 1
d) no solution
Step-by-step explanation:
An absolute value inequality of the form |f(x)| ? a resolves to two inequalities:
±f(x) ? a
where ? is some comparison symbol.
__
a) |x +2| > 1
resolves to the inequalities ...
x + 2 > 1 ⇒ x > -1
and the other inequality this resolves to is ...
-(x +2) > 1
-x -2 > 1
-x > 3
x < -3
Then the solution is the union of the disjoint solution spaces:
(x < -3) ∪ (-1 < x)
__
b) |2(x -1)| ≥ 0
2(x -1) ≥ 0 ⇒ x ≥ 1
and the other inequality this resolves to is ...
-2(x -1) ≥ 0
x -1 ≤ 0 . . . . . divide by -2
x ≤ 1
The union of these solutions is ...
x ∈ all real numbers
__
c) 9x -4 ≤ 6 -x
10x ≤ 10 . . . . . . add x+4 to both sides
x ≤ 1 . . . . . . . . . divide by 10
__
d) No solution. (An absolute value cannot be negative.)
__
The attachment shows the solutions plotted against a number line.
_____
Additional comment
When the inequality is of the form ...
|f(x)| < a
it can be written as the compound inequality ...
-a < f(x) < a
If the comparison is > instead of <, using the same "expansion" results in an inconsistency:
-a > f(x) > a . . . . . . never true for a > 0
If you ignore that technicality (which your teacher may not understand), you can do the solution in the same way you would for the other inequality symbol(s). Just remember the result should be the union of the two disjoint solution spaces.
Using (a) as an example:
-1 > x+2 > 1 . . . . . to solve this, we subtract 2 everywhere
-3 > x > -1 ⇒ the solution is (-3>x) ∪ (x>-1)

Malik randomly picked two different numbers from 1 to 9. The first one was odd. What is the probability that Malik picked a second odd number given that the first number was odd?
Answer:
The probability that the second number is odd is 50%.
Step-by-step explanation:
Given that Malik randomly picked two different numbers from 1 to 9, and the first one was odd, to determine what is the probability that Malik picked a second odd number given that the first number was odd, the following calculation must be performed:
Odd numbers = 1 - 3 - 5 - 7 - 9 = 5 odd numbers
Even numbers = 2 - 4 - 6 - 8 = 4 even numbers
4/8 = 0.5 x 100 = 50%
Therefore, if from 1 to 9 an odd number was obtained, 8 numbers remain, of which 4 are odd. Therefore, the probability that the second number is odd is 50%.
Answer:
The answer for plato is 2/9
Step-by-step explanation:
What is the probability that the sum of the two numbers Malik picks is less than 5, given that the first number is odd and less than 5?

Answer:
Hello! answers:
Question 13: 12
Question 14: 18
Question 15: 15
Hope that helps!
For question 13 I found the answer by doing 6 ÷ 2 and 6 ÷ 2 = 3 so I know that 4 will be enlarged by 3 so 4 × 3 = 12 so 12 is the answer for 13
For question 14 I found the answer by using 1 of the sides so I did 24 ÷ 16 and 24 ÷ 16 = 1.5 and 1.5 × 12 = 18 so the answer is 18
For question 15 I did the same thing!
25 ÷ 20 = 1.25 and 1.25 × 12 = 15 so 15 is the answer Hope that helps!

A) a=80
b=100
B) a=60
b=120
C) a=70
b=110
D) a=72
b= 108
Please help thank you
Answer:
Your right the answer is B a=60 , b=120
A ratio of 1:2 just means one value is twice that of the other.
Answer:
B (a=60, b=120)
Step-by-step explanation:
1. m∠AOB = 180°
2. Since the ratio of a to b is 1:2, set the measure of a as x, and the measure of b as 2x.
3. a+b = 180, so x+2x = 180, 3x = 180, x = 60
4. x = a, so if x=60, then a = 60
5. if b=2x, then b = 2a, which is 2*60 = 120

A spinner has A-H on it.
What is the probability of spinning a vowel and rolling an even number on a standard dice?
NO LINKS
a
1/3
b
3/4
c
1/8
d
5/40
Answer: 1/8
Step-by-step explanation:
1) A B C D E F G H -> The probability of spinning a vowel is 2/8.
2) 1 2 3 4 5 6 -> The probability of rolling an even number on a standard dice is 3/6.
3. To find the probability of spinning a vowel and rolling an even number on a standard dice, we just have to multiply both of the probabilities:
2/8 * 3/6 = 6/48.
4. Simplify 6/48 and you get -> 1/8.
