Find the exact value of Cosine (alpha + beta) given sin Alpha = two-fifths for Alpha in Quadrant II and Cosine Beta = one-third for Beta in Quadrant IV.

Answers

The exact value of cos (α + β) is (4√2-21) / 15.

What is angle?

An angle is the formed when two straight lines meet at one point, it is denoted by θ.

Given that,

Sin α = 2/5, and α is in second quadrant,

cos β = 1/3 , and β is in fourth quadrant

Since, α is in second quadrant, the value of cos α will be negative.

The value of cos α, by right angle triangle property,

cos α = -√21 / 5  

Since, β is in the fourth quadrant, the value of  sin β will be negative.

The value of sin β  = -  2√2 / 3

Cos (α + β) = cos α.cos β - sin α. sin β

Substitute the values here,

Cos (α + β) = (-√21 / 5)  . 1/3 - 2/5. ( -  2√2 / 3)

                   = -21/15 + 4√2/15

                   =  (4√2-21) / 15

The value of cos (α + β) is (4√2-21) / 15.

1 - Rewrite

b = 75 + 15n; b = 130

2 - Plug in and get n alone

130 = 75 + 15n

- 75  -75

55 = 15n ←↓ Divide both sides by 15

Write the equation of a line that is
parallel to y = 0.5x + 6 and
passes through the point (6, -2).​

Answers

Answer:

[tex]y=0.5x-5[/tex]

Step-by-step explanation:

Since the equation is parallel, this means that the slope remains the same which is 0.5.

The remaining thing to do is to find b or y-intercept. To do that, the point (6,-2) and the slope of 0.5 will be used.

[tex]-2=0.5(6)+b[/tex]

When solving for b, it will equal to -5.

Therefore the new equation that is parallel is [tex]y=0.5x-5[/tex]

The equation of a line parallel to y = 0.5x + 6 and passes through the point (6, -2) is y = 0.5x + 1.

What are lines and their slopes?

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

We know lines parallel to each other have the same slope.

The given line can be written as y = 0.5x + 6.

Therefore, The required line also has a slope of 0.5 passing through the point (6, -2).​

- 2 = 0.5×6 + b.

- 2 = - 3 + b.

b = 1.

So, y = 0.5x + 1.
