Let sin(2x)-sin(x)=0, where 0 ≤ x < 2pi. What are the possible solutions for x?
Answers
Step-by-step explanation:
sin2x - sinx = 0
2sinxcosx - sinx = 0
(Double Angle Formula)
sinx(2cosx - 1) = 0
Either sinx = 0 or cosx = 1/2.
When sinx = 0,
x = 0 or x = π.
When cosx = 1/2,
x = π/3 or x = 5π/3.
Hence the solutions are
x = 0, x = π/3, x = π or x = 5π/3.

Evaluate the function. g(x) = 3x^2 – 2x + 5 Find f(2)
Answers
Answer:
13
Step-by-step explanation:
Replace X with 2
Evaluate the function. g(x) = 3x^2 – 2x + 5 Find f(2)
g(x) = 3(2)^2 – 2(2) + 5
Next conduct PEMDAS
Exponents are first so solve 2^2 which is 2 x 2 = 4
g(x) = 3(4) – 2(2) + 5
Next step is multiplication multiply 3 x 4 and 2x2
g(x) = 12 – 4 + 5
conduct adding and subtracting left from right
g(x) = 13

Complete the solution of the equation. Find the
value of y when x equals 15.
-3x - y = -51
Answers
Answer:
The solution of the equation y = 36
Step-by-step explanation:
Explanation:-
Given equation -3x-y =-51
Given that x =15 in equation -3x-y=-51

[tex]\frac{25}{100}[/tex]
Step-by-step explanation:
Hey there !!!!!
to find the correct answer to this question you just divide :
the options are 25/10 , 2/5 , 10 / 25 and 25/100
so, you divide each one of them :
25/10 = 25 ÷ 10
2/5 = 2 ÷ 5
10/25 = 10÷25
25/100 = 25÷100
if you divide each one of them:
25 ÷ 10 = 2.5
2 ÷ 5 = 0.4
10÷25 = 0.4
25÷100 = 0.25
therefore:
25/100 is the answer

The sum of two numbers is 10. Their difference is 6. What are the two numbers?
Answers
Answer: 8 and 2
Step-by-step explanation:
this is simple, since we only have 10 numbers to work with. i just kept experimenting with numbers until i got one that had a difference of 6. no strategy, just brain power. hope this helps! xoxo
Answer:
So negatove numbers are gonna be impossible becuase we know that the highest we can go is -10+20=10 but it’ll give a whole different difference when subtracted.
And it can’t be greater then 10 becuase if you do add them it won’t be 10
SO it has to be between 1-10
So what equals 10?
5/5
2/8
8/2
6/4
4/6
3/7
7/3
Now 5 and 5 is out cause if subtracted its 0
2/8 and 8/2 works, if added you get 10 but when subtracked the way for 8/2 from left to write it’ll give 6 which is the only one which will give.
final answer the two numbers are 8 and 2

The ratio of males to females at a party is 3 : 5
There are 12 more females than males.
How many people are at the party?
Answers
Answer:
48
Step-by-step explanation:
Given ratio of males to females at a party is 3 : 5.
Let the numbers of males and females be 3x and 5x respectively.
According to the given description:
No of females = No of males + 13
Therefore,
5x = 3x + 12
5x - 3x = 12
2x = 12
x = 12/2
x = 6
No of people at the party
= 3x + 5x
= 8x
= 8*6
= 48
