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

Answer:
The chart shows a growth of 22-24 miles per gallon.
Step-by-step explanation:
I don’t know which one is correct.
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

Answer:
Neither triangle
Step-by-step explanation:
Define an irrational number that cannot be written as a fraction (denominator of 1 or 0 does are excluded).
Both triangles are good examples of common Pythagorean triples.
The Pythagorean theorem states that for any right triangle, the following is true:
[tex]a^2+b^2=c^2[/tex], where [tex]a[/tex] and [tex]b[/tex] are two legs of the triangle and [tex]c[/tex] is the hypotenuse.
Using this theorem we can solve for the hypotenuse of both triangles:
Triangle 1:
[tex]3^2+4^2=h^2,\\h^2=25,\\h=5\:\text{(rational)}[/tex]
Triangle 2:
[tex]0.5^2+1.2^2=h^2,\\h^2=1.69,\\h=1.3\:\text{(rational)}[/tex]

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:
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)

Q6. The diagram shows two similar solids, A and B.
Solid A has a volume of 80 cm.
(a)
Work out the volume of solid B.
Answer:
640cm³
Step-by-step explanation:
Length SF = ×2
Volume SF = ×2³ = ×8
Volume of B = 8 × 80 = 640cm³
The volume of the scale factor is 8. Then the volume of the solid B will be 640 cm³.
What is the volume?Volume is a measurement of three-dimensional space that is utilized. It is frequently mathematically quantified using SI-derived units or different imperial or US traditional units. The concept of length is linked to the notion of capacity.
The diagram shows two similar solids, A and B. Solid A has a volume of 80 cm³.
The scale factor is given as,
Scale factor = 8 / 4
Scale factor = 2
The scale factor of the volume is given as,
⇒ 2³
⇒ 8
Then the volume of the solid B will be given as,
Volume of B = 8 x 80
Volume of B = 640 cm³
The volume of the scale factor is 8. Then the volume of the solid B will be 640 cm³.

I WILL GIVE BRIANLIEST TO THE FIRST PERSON TO ANSWER 13,14,15 AND EXTRA POINTS
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!
