I don’t understand how to do this problem and get all the other answers, if you can help me that would be great!

Alecsey [184]

Answer:

Step-by-step explanation:

You can’t just substitute 0 for θ. 0 is a constant, not a variable.

secθ = -13/5

cosθ = 1/secθ = -5/13

sin²θ = 1 - cos²θ = 144/169

sinθ = -12/13

cscθ = 1/sinθ = -13/12

tanθ = sinθ/cosθ = 12/5

cotθ = 1/tanθ = 5/12

Solve this system of equations. x + y = -3 x - y = 1

Sindrei [870]

x + y = -3
-1 + (-2) = -3
-3 = -3

x - y = 1
-1 - (-2) = 1
-1 + 2 = 1
1 = 1

The population of the United States was about 280 million in 2000 and about 310 million in 2010. What was the annual rate of cha

JulsSmile [24]

To find the annual rate of chnge, we have to use the following formula

$\frac{P(2010)-P(2000)}{2010-2000}$

P(2010) represents the population in the year 2010 and P(2000) represents the population in the year 2000 .

Substituting the values, we will get

$\frac{310-280}{2010-2000} = \frac{30}{10} = 3 \ million \ per \ year$
