In the figure below, if sin x= 5/13, what are cos x and tan x? PLZ HELP FOR THE LOVE OF GOD AND WHTS GOOD IN THE WORLD HELPPP

Sunny_sXe [5.5K]

Answer:

Step-by-step explanation:

cos²x = 1-sin²x = 1-(5/13)² = 144/169

cosx = √(144/169) = 12/13

tanx = sinx/cosx = (5/13)/(12/13) = (5/13)×(13/12) = 5/12

How to evaluate and simplify

Kobotan [32]

Answer:

depends.

Step-by-step explanation:

Evaluating a question depends on the question given. To simplify an answer, you need to find the simplest answer, this process also depends on what question you're given, for example, if you simplify 4/8 (four eighths), it would be 1/2 (one half).

The image of the car park showing the 2 angles is attached.

Answer:

Their lines are parallel.

Step-by-step explanation:

From the attached image, we can see that ∠1 and ∠2 form a pair of alternate exterior angles. Thus; ∠1 = ∠2.

Now since they are congruent, it means that their lines will be parallel.

Thus, we can conclude that their lines are parallel.

The number of camera phones shipped globally can be modeled by the function y = 1.28e 1.31x where x is the number of years since

OlgaM077 [116]

Answer: 895 phones

Step-by-step explanation:

Given that :

The function : y = 1.28e^1.31x ; is used to model the number of camera phones shipped since 1997

y = number of camera phones ; x = number of years since 1997

The number of camera phones shipped in the year 2002 can be obtained thus ;

x = 2002 - 1997 = 5 years

y = 1.28e^(1.31 * 5)

y = 1.28e^6.55

y = 1.28(699.24417)

y = 895.03254

y = 895 phones

Which equation represents the line that passes through (–6, 7) and (–3, 6)? y = –y equals negative startfraction one-third endfr

egoroff_w [7]

The equation represents the line that passes through (–6, 7) and (–3, 6) $\rm y=\dfrac{-1}{3}x+5$ .

<h3>What is the slope of the equation?</h3>

For all lines in slope y-intercept form, it would be very simple to just find the answer by finding yourself the slope and y-intercept of the line in question.

The slope of the line is;

$\rm m = \dfrac{y_2-y_1}{x_2-x_1}\\\\m =\dfrac{7-6}{-6-(-3)}\\\\m = \dfrac{1}{-3}$
