If sin A = .5 and cos A = .866 then what is tan A to the nearest thousandth

Answers

Answer 1

Answer: Somewhere in a table of trig-function definitions that you have somewhere,
it mentions that

tan(a) = sin(a) / cos(a).

So it must follow that

tan(A) = (0.500) / (0.866) = 0.577 (rounded)

We can do this by inputting -2 as x in this equation. This would get us f(x) = 3(-2)-4 = -6-4 = 10. The answer is -10. Hope this helps!

Endpoints of major axis at (0,6) and (0,-6) endpoints of minor axis at (-3,0) and (3,0)

Answers

we can see that the center is (0,0)

and from commments we know tat it is ellipse

since major axis is y direction ( and center (0,0)), it is a vertical ellipse
in form
$(x^(2))/(b^(2)) + (y^(2))/(a^(2)) =1$

where a is the distance from the center to major axis end
b is distance of minor axis
and a>b always for ellipse

from (0,0) to (0,6) is 6 units, major axis
from (0,0) to (3,0) is 3 units, minor axis

$(x^(2))/(3^(2)) + (y^(2))/(6^(2)) =1$

Give the slope and y-intercept ofthe line.
slope = [?], y-intercept = [ ]
Enter the number that belongs in the green box.
Enter

Answers

Answer:

Slope = 2, y-intercept = 3

Step-by-step explanation:

I will be calculating the slope of the line using these two points: (-1, 1) and (0, 3)

Slope = $(rise)/(run)$

= $(3-1)/(0-(-1))$

= $(3-1)/(0+1)$

= 2

Based on the graph, the y-intercept is 3.

What will be the linear equation for the shown table?

Answers

Answer:

y=2x+5

Step-by-step explanation:

To find a linear equation you must find the slope and y intercept to create an equation in y=mx+b form (slope-intercept form)

So slope is = y2-y1 / x2-x1 [2 and 1 are subscripts] so 11-7/3-1 so m=4/2 = 2

Slope = 2, now find b

So using y = mx + b, substitute what you know so 7 = 2(1) + b so b=7-2 = 5

Put it all together y = 2x + 5

11. Quadrilateral GHJK is similar toquadrilateral RSTU. If GH = JK = 10,
HJ = KG = 14, and RS = TU = 16, what is
the scale factor of quadrilateral GHJK to
quadrilateral RSTU?

Answers

Answer: the scale factor is 1.6

Step-by-step explanation:

The attached photo shows Quadrilateral GHJK and Quadrilateral RSTU. Since they are similar quadrilaterals,

KG/UR = JG/TS = GH/RS = KJ/UT

10/16 = 14/TS

10TS = 16×14 = 224

TS = UR = 224/10 = 22.4

The scale factor is

16/10 = 22.4/12 = 1.6
