cos θ = 13/85, tan θ = 84/13, sec θ = 85/13, csc θ = 85/84

Step-by-step explanation:

θ in 1st quadrant, all the coordinates are positive

sin θ = 84/85 (for the right angle triangle ABC, A is the right angle and a the hypotenuse, b and c are legs. )

a = 85

b = 84

c = √85² - 84² = 13

cos θ = 13/85, tan θ = 84/13, sec θ = 85/13, csc θ = 85/84

Are the ratios 2:3 and 4:6 equivalent? Explain your answer. PLSS HELP ME

MrMuchimi

Answer: Yes

Step-by-step explanation:

2:3 is the same as (2/3) and 4:6 is the same as (4/6). (4/6) can be reduced by dividing both sides by 1/22: (4/6)*(1/2)/(1/2) = 2/3, They are the same.

In MODE, (second line), fix the number of decimal places to be 2. Then the slope and the y-intercept values of the LinReg line w

olasank [31]

The equation of line is y = 92x - 182631. The slope is 92 and the y-intercept is - 182631. And the health expenditure in 2010 will be 2289.

<h3>What is the equation of a line passing through two points?</h3>

Suppose the given points are (x₁, y₁) and (x₂, y₂), then the equation of the straight line joining both two points is given by

$\rm (y - y_1) = \left [ \dfrac{y_2 - y_1}{x_2 - x_1} \right ] (x -x_1)$

In MODE, (second line), fix the number of decimal places to be 2.

Then the slope and the y-intercept values of the Lin Reg line will round to the nearest hundredth.

(x₁, y₁) → (1997, 1093)

(x₂, y₂) → (2002, 1553)

Then we have

y – 1093 = [(1553 – 1093) / (2002 – 1997)] (x – 1997)

y – 1093 = [460 / 5] (x – 1997)

y – 1093 = 92 (x – 1997)

y = 92x – 182631

If x = 2010, then the value of y will be

y = 92 × 2010 – 182631

y = 184920 – 192631

y = 2289

(2ab+9a-4) - (ab+2)

skad [1K]

Answer:

$\boxed{\bold{ab+9a-6}}$

Step-by-step explanation:

Remove parenthesis: (a) = a

$\bold{2ab+9a-4-\left(ab+2\right)}$

$\bold{-\left(ab+2\right): \ -ab-2}$

$\bold{2ab+9a-4-ab-2}$

Simplify $\bold{2ab+9a-4-ab-2}$

$\bold{ab+9a-6}$

Mia had 5000 In the bank. She keeps the money in the bank for 4 years at 5% interest. How much interest did she earn?

viktelen [127]

Simple interest formula:
Interest = P*R*N

P = principle amount
R = interest rate (in decimal)
N = number of time periods (in years)

Interest = 5000*0.05*4 = $1000

Can somebody please tell me what 1 1/3+(−5/6) is??

Dafna11 [192]

Answer:

1/2

Step-by-step explanation:

Hi there !

1 1/3 + (-5/6) =

= (1*3+1)/3 - 5/6

= ²⁾4/3 - 5/6

= 8/6 - 5/6

= (8 - 5)/6

= 3/6

= 1/2

Good luck !
