4sinθ – 1 = - 3 for 0<θ< 360

Mathematics
1 answer:
EastWind [94]3 years ago
7 0

Answer:

\theta = 210^\circ or \theta = 330^\circ

Step-by-step explanation:

4 \sin \theta - 1 = -3

4 \sin \theta = -2

\sin \theta = \dfrac{-2}{4}

\sin \theta = -0.5

For sin θ = 0.5, the reference angle is θ = 30 deg.

\sin 30^\circ = 0.5

\theta = 210^\circ or \theta = 330^\circ

Slope -8 and y intercept 7
max2010maxim [7]

Answer:

The equation of Line is  y = - 8x + 7      

Step-by-step explanation:

Given as :

The slop of line is - 8

And The y intercept is 7

As the equation of line is y = mx + c

For y intercept , x = 0

So, With y intercept and slop ,

7 = (-8)× (0)+ c

Or, c = 7

So the equation of line is

y = mx + c

I.e  y = ( - 8 ) x + 7

Hence The equation of Line is  y = - 8x + 7       Answer

What is the volume, in cubic meters, if the prism below?
Fiesta28 [93]
<h3>Answer:   1848 cubic meters</h3>

=================================================================

Explanation:

Imagine rotating the figure so that the triangular face is flat on the ground. This makes the triangular faces to be the floor and ceiling of this room.

The floor is a triangle with base 24 meters and height 7 meters. The floor area is base*height/2 = 24*7/2 = 84 square meters.

Multiply this floor area with the height of the room (22 m) to get the volume of the room.

volume = (floor area)*(height) = 84*22 = 1848 cubic meters
