Let sin(2x)-sin(x)=0, where 0 ≤ x < 2pi. What are the possible solutions for x?
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)
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

A math teacher said that 18 out of 25 students passed the test. What percent of the students did NOT pass the test?
Answer:
28% of the class didn't pass the test.
Step-by-step explanation:
25 - 18 = 7
7/25 = 0.28 or 28%
Thus, 28% of the class didn't pass the test.
Which is the same as 0.25?
Answer:
[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

Kate has 48 softballs. She wants to divide them evenly among b softball bags. Which expression represents how many softballs she should put into each bag?
Answer:
Softballs = (48/b)
Step-by-step explanation:
Given that,
Total number of softballs = 48
She wants to divide them evenly among b softball bags.
We need to find an expression that represents how many softballs she should put into each bag.
As it is dividing among b softball, it means we divide 48 and b. So,
[tex]s=\dfrac{48}{b}[/tex]
Hence, the required expression is (48/b).

Complete the solution of the equation. Find the
value of y when x equals 15.
-3x - y = -51
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
⇒ - 3(15) - y = -51
⇒ - 15 - y =-51
⇒ -15+ 51 = y
⇒ y = 36

Maria's Grocery Store buys grapefruit at a cost
of 5 for a dollar. They sell them at a price of 5
for three dollars. How many must they sell in
order to make a profit of ten dollars?
Answer: 25 grapefruits
Step-by-step explanation:
They buy grapefruit at a price of 5 per dollar. This means that the price per grapefruit is:
= 1 / 5
= $0.20 per grapefruit.
They then sell at a price of 5 per $3. The selling price per grapefruit is:
= 3 / 5
= $0.60
The profit per grapefruit is:
= 0.60 - 0.20
= $0.40
In order to make a profit of $10, they should sell:
= 10 / 0.4
= 25 grapefruits
