Answer:

Step-by-step explanation:

it can be simplified to \frac{sec \theta}{cot\theta+tan\theta} =sin\theta  . if you multiply each side by the denominator, it becomes sec\theta=\frac{sin^2\theta}{cos\theta} + cos\theta since tan\theta=\frac{sin\theta}{cos\theta} and cotan is the reciprocal of that. Because sec\theta=\frac{1}{cos\theta} so multiplying each side gives 1=sin^2\theta+cos^2\theta, and sin^2\theta+cos^2\theta is equal to 1.

Answer:

1)28.8%

2)28.8%

3)43.6%

Step-by-step explanation:

1))Probability of wining both = Probability that first contract is won* Probability that second contract is won = 0.4 * 0.72 = 0.288 = 28.8%

2)Probability of losing = 1 - Probability of winning

Probability that they will lose both contracts = Probability that first contract is lost * Probability that second contract is lost = (1 - 40/100) * (1 - 54/100) = 0.276 = 27.6%

3)Probability that any one is won = 1 - both contracts are won - both contracts are lost = 1 - 0.276 - 0.288 = 0.436 = 43.6%

What is the equation of the line that passes through the point (6, 3) and has a slope of -2?
tekilochka [14]

We know the equation of a line is y=mx+b. We know the slope (m) is -2 and all we need is the intercept (b).

Since we know one point, we can plug in 6 for x and 3 for y (along with -2 for m) in our equation and then solve for b.

3= -2*6 + b

3= -12 + b

15 = b

Since we now know the intercept we can now write our equation:

y= -2x + 15
