sin^2 a/2 - sin a/2 + 1/4 = 0
Answer:
a = 60° or π/3
Step-by-step explanation:
Given :-
sin² a/2 - sin a/2 + 1/4
To find :-
a
Solving :-
sin² a/2 - sin a/2 + 1/4 = (sin a/2 - 1/2)² = 0
sin a/2 - 1/2 = 0
sin a/2 = 1/2
a/2 = 30°

39 - 12w =7- 16w
iIl give a brainliest
Answer:
w=-8
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
39−12w=7−16w
39+−12w=7+−16w
−12w+39=−16w+7
Step 2: Add 16w to both sides.
−12w+39+16w=−16w+7+16w
4w+39=7
Step 3: Subtract 39 from both sides.
4w+39−39=7−39
4w=−32
Step 4: Divide both sides by 4.
4w/4=-32/4

do you agree with Craig explain why or why not
The dot on the number line, that Craig says shows a value of one third
is halfway between 0 and one half which is one quarter therefore;
The number line indicates 1/4 rather than 1/3How can the values on the number line be found?A possible number line obtained from a similar question posted on a

From the attached drawing, we have, that the half-way marking between
1 and 0 is 2/3, and the half way between 0 and 2/3 is 1/3. However, half
between 0, and 1 is 1/2
Therefore, the half-way marking should be 1/2 rather than 2/3

Which numbers complete the blanks when solving the equation cos(x+2pi)= -(square root of 2/2) over the interval [0, 2pi]?
Answer:
1, 0
Step-by-step explanation:
Let [tex]\cos (x+2\pi) = -\frac{\sqrt{2}}{2}[/tex]. From Trigonometry we remember the following identity:
[tex]\cos (a+b) = \cos a \cdot \cos b - \sin a \cdot \sin b[/tex] (Eq. 1)
Where [tex]a[/tex] and [tex]b[/tex] are angles measured in radians.
Then, we proceed to expand the given expression:
[tex]\cos x \cdot \cos 2\pi - \sin x \cdot \sin 2\pi = -\frac{\sqrt{2}}{2}[/tex]
[tex]\cos x \cdot 1 - \sin x \cdot 0 = -\frac{\sqrt{2}}{2}[/tex]
[tex]\cos x = -\frac{\sqrt{2}}{2}[/tex]
Therefore, correct answer is "1, 0".

Seventy-five students randomly selected from the junior class at a high school were given a survey asking how much time they spent studying for a math test. Assume the population is normally distributed. The population is The sample is.
Population is like superset of sample. The population and sample for this case are:
Population is: The junior class' students of the considered high schoolSample is: Those 75 randomly selected students.What is the difference between population and sample?The difference between population and sample is that sample is taken from the population.
Why do we do sampling?We do sampling so that we don't have to work on entire population of items but only on that sample in a way that we can predict information about population.
Most of the times, it isn't possible in real world to work on entire populations. Samples come out for rescue by assumptions that they will have some properties of the population pertained in them.
Thus, the sample should be taken out such that it includes data of the population as much as it can in unbiased way so as to imitate population.
For this case, we have:
75 students were randomly selected from the junior class at a high school.
Since 75 students were selected from junior class, thus:
the population was: The junior class' students of that high schooland, the sample was: Those 75 randomly selected students.Learn more about sampling here:

Hello people ~
factorise: x^2 + 15x + 26
Answer:
(x +13)(x + 2)
Step-by-step explanation:
Sum = 15
Product = 26
Factors = 2 , 13
When we add the factors , we get 15 ( 13 +2 = 15)
When we multiply 2 and 13, we get 26 (13*2 = 26)
x² + 15x + 26 = x² + 13x +2x + 26
=x(x + 13) + 2(x + 13)
= (x +13)(x + 2)
So far as to attempt this question we can do either it by factorisation method by creating factors OR by splitting middle term method.
[tex]\mapsto\sf{ {x}^{2} + 15x + 26}[/tex]
Splitting middle term 15x in terms of 13x and 2x gives their sum to 15x and their product is equal to 26.
[tex]\mapsto\sf{ {x}^{2} + 13x + 2x + 26 = 0}[/tex]
[tex]\mapsto\sf{x(x + 13) + 2(x + 13)} = 0[/tex]
[tex]\mapsto\sf{(x + 2)(x + 13) = 0}[/tex]
CASE 1:
[tex]\mapsto\sf{x + 2 = 0}[/tex]
CASE 2:
[tex]\mapsto\sf{x + 13 = 0}[/tex]
Thus,
[tex]\sf{ \therefore \: ( {x}^{2} + 15x + 26) = (x + 2)(x + 13)}[/tex]
