How would you set up this problem to find the height of the sail using reciprocal functions?

AVprozaik [17]

Remark

I'm not sure I know what you mean, but I will answer trying to interpret it so it fits the description of the question.

Step One: Set up the equation. The normal way of solving this would be to use the Cos function.

Cos(theta) = Adjacent / hypotenuse = x/8 Multiply both sides by 8

8*cos(theta) = x Theta = 35

8*cos(35) = x This is about as simple a way as is possible.

6.553 = the height of the sale.

Step Three: try using the reciprocal

1 / cos(35)= hypotenuse / adjacent

1/0.8191 = 8/x cross multiply

x = 0.8191 * 8

x = 6.553

Graph: y - 3 = 1/2 (x + 2)

11Alexandr11 [23.1K]

Answer:

Slope: $\frac{1}{2}$

Y-intercept: (0,4)

Step-by-step explanation:

Put the equation into y = mx + b form, which is y = $\frac{1}{2}$ +4. Then create a table.

X: -2, -1, 0, 1, 2

Y: 3, $\frac{7}{2}$ , 4, $\frac{9}{2}$ , 5

What is the equation of the axis of symmetry of this parabola? y=-5(x+4)^2+3

Ede4ka [16]

Answer:

$x=-4$

Step-by-step explanation:

Given the equation of parabola

$y=-5(x+4)^2+3$

This is the vertex form of the parabola equation. Hence, the vertex of the parabola is at point $(-4,3)$

This parabole goes downwards in y-direction (the leading coefficient -5 is negative)

<u>The axis of symmetry</u> of parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.

Thus, the equation of the axis of symmetry is

$x=-4$
