Note that
sin(x + y) = sin(x) cos(y) + cos(x) sin(y).

Therefore by setting x = π/2 and y = π/7, obtain
sin(π/2 + π/7) = sin(π/2)*cos(π/7) + cos(π/2)*sin(π/7)

The right side is what we want to evaluate.  It is equal to
sin(π/2 + π/7) = sin (9/14)π

Answer:  sin( \frac{9 \pi }{14})

The equation and table shows were two boys pay for gym fees compare the rate of change and initial value for each function
Olegator [25]

The equation is an illustration of a linear function

The rate of change is 10 and the initial value is 25

<h3>How to determine the rate of change and the initial value</h3>

The equation is given as:

C = 25 + 10m

A linear equation is represented as:

y = b +  mx

Where:

  • b represents the initial value
  • m represents the rate

By comparison:

b = 25

m = 10

Hence, the rate of change is 10 and the initial value is 25

Help! Stuck on this one!
gtnhenbr [62]

so we know that each m&m weighs about 2g.

the next line says to write a direct variation equation.

(definition: mathematical relationship between two variables that can be expressed by an equation in which one variable is equal to a constant times the other)

we then make the equation ( w=xm), then we use that equation to figure out the next line, which is to find the amount of m&ms that would fit in a bag of 1000.

(my head cant really process part a cause of a recent headache, so sorry if its wrong)

the answer to part b would be 500, which you can provide evidence based off of your part a equation.

Line L passes through the point (-1, 1) and is PARALLEL to the line shown here. An equation of line L is
Pachacha [2.7K]
The problem cannot be fully solved because you did provide the line on which the line is parallel/ but i can give you the steps on how to solve it. first solve the slope of the parallel line by
m = ( y2 - y1 ) / ( x2 - x1 )
then the slope of that line is equal to slope of line passing pooint ( -1 , 1)
then solve the y intercept of the line using
y = mx + b
where b is the y intercept
then you will have the equation of the line
