Nastasia [14]3 years ago
4 0

Answer:

C)   (-3, -1)

Step-by-step explanation:

y = 5/3x + 4

  When x = 0, y = 4

  When y = 0, x = -2.4

  graph the points: (0, 4) and (-2.4, 0)

y = -2/3x - 3

  When x = 0, y = -3

  When y = 0, x = -4.5

  graph the points: (0, -3) and (-4.5, 0)

The lines will cross at point: (-3, -1)

find sin(alpha-beta) if sin alpha =-5/13 with alpha between pi and 3pi/2; cos beta=2/5 with beta between 3pi/2 and 2pi
ludmilkaskok [199]
        sin(α) = ⁻⁵/₁₃
sin⁻¹[sin(α)] = sin⁻¹(⁻⁵/₁₃)
               α ≈ 1.1256π

          cos(β) = ²/₅
cos⁻¹[cos(β)] = cos⁻¹(²/₅)
                 β ≈ 1.6311π

sin(α - β) = sin(1.1256π - 1.6311π)
sin(α - β) = sin(-0.5055π)
sin(α - β) = -sin(0.5055π)
sin(α - β) = -sin(90.99)
sin(α - β) ≈ -0.116

Calculate the area of the shaded sector in the circle​
agasfer [191]

Answer:

Approximately, 6.283..

Step-by-step explanation:

First calculate the area of the whole circle

We have radius(r)=4 cm

Area of circle(a)=pir^2

=pi×(4)^2

=pi×16

=Approximately,50.265......

A cirlce has a total of 360 degrees

Therefore,we can conclude 360 degrees=50.265...

or,1 degree=50.265/360

1 degree=Approximately,0.139

Now,

Area for the shaded region = Area of 45 degree

=0.139×45=Approximately,6.283.....

Therefore,the area of the shaded region is approximately,6.283....
