A scatter plot is generally used when displaying data from two variables that may or may not be directly related, and when neither of the variables is under the direct control of the researcher. The primary function is to illustrate a correlation.
cos θ = Adjacent/ hypotenuse
cosθ= 5/13
a²+b²= c²
a² + 5² = 13²
a² = 13² - 5²
a² = 144
a=√144
a= 12
<u>a</u> is the opposite = 12
<u>b</u> is the Adjacent = 5
<u>c</u> is the hypotenuse = 13
a) tan θ= opposite/Adjacent
tan θ = 12/5
b) sin θ= opposite/ hypotenuse
sinθ= 12/13
C) sec θ= hypotenuse / Adjacent
sec θ= 13/5
d) cscθ= hypotenuse /opposite
cscθ= 13/12
e) cotθ=Adjacent/ opposite
cotθ= 5/12
Begin by multiplying everything by 3 to get rid of the fraction. That gives us

. The rule is when you divide by a negative, the direction of the sign changes, so we will end up with

. Because there is a line under the inequality sign, the circle is closed. So your choices are the second, fourth, and sixth.
Answer:

Step-by-step explanation:
Step 1:

Step 2:
Then multiply both by 1000

It cant be simplifyed further so its in simplest form
Answer:
2x-106
Step-by-step explanation:
-7(x+10)+9(x-4)
Expand parentheses:
-7x-70+9x-36
Combine like terms:
2x-106
Hope this helps!
