6 0

Answer:

cscα=√2

Step-by-step explanation:

Problem: If sinα-cosα=θ find cscα

Solution:

sinα-cosα=θ

sinα=cosα

sinα=sin(90-α)

If α<90, then:

α=90-α

2α=90

α=45°

sin(45°)

1/sin(45°)

csc(45°)

√2

Therefore, cscα=√2 if sinα-cosα=θ

I need help on this please
tresset_1 [31]

Answer:

The y-intercept is (0, 8)

The x-intercepts are (2, 0) and (4, 0)

The axis of symmetry is a vertical line at x = 3

The vertex is (3, -1)

The graph has a minimum value -1 at x = 3

The domain is {x: x ∈ R} ⇒ (-∞, ∞)

The range is {y: y ≥ -1} ⇒ [-1, ∞)

Step-by-step explanation:

By using the given figure

The figure represents a parabola (the graph of a quadratic function

∵ The parabola intersects the y-axis at point (0, 8)

∴ The y-intercept is (0, 8)

∵ The parabola intersects the x-axis at point (2, 0) and (4, 0)

∴ The x-intercepts are (2, 0) and (4, 0)

∵ The axis of symmetry of the parabola is a vertical line that passes

  through the vertex of it

∵ The x-coordinate of the vertex point is 3

∴ The axis of symmetry is a vertical line at x = 3

∵ The vertex of the parabola is the lowest point on the graph

∵ The lowest point is (3, -1)

∴ The vertex is (3, -1)

∵ The vertex point of the graph is the lowest

∴ The graph has a minimum value -1 at x = 3

∵ The domain is all values of x belong to the parabola

∵ x could be any real number

∴ The domain is {x: x ∈ R} ⇒ (-∞, ∞)

∵ The range is all the values of y from the lowest point

∵ The y-coordinate of the lowest point is -1

∴ The range is {y: y ≥ -1} ⇒ [-1, ∞)

Find the slope of the line through each pair of points (-3, 1), (-17, 2)​
dem82 [27]

To help solve this, we need to use the slope formula.

(y2 - y1) / (x2 - x1). We get these values by picking two points on a line.

We will use points (-3, 1) and (-17, 2).

y1 = 1

y2 = 2

x1 = -3

x2 = -17

Let's plug these into our formula.

(2) - (1) / (-17) - (-3) = 1 / - 14

The slope is 1 / -14
