You can substitute a number in for x and compare the answer choices (not the most efficient way but it's how I would do it). Let's just say x = 5. Then the expression would equal 0.25819889. Substitute 5 in for x is the answer choices and see which one is the same.
A) simplified is 0.004 repeating
B) simplified is 0.25819889
C) simplified is 0.12
D) simplified is 1.341640786
We can see that B is the right answer
To find which orders pairs fit into the inequality simply substitute the variables, x & y.
A:3*8+4*(-3)>=12, yep! 12>=12
B: 3*(-5)+4*2>=12, Nope! -7 is not >= 12
C:Yep! 20>=12
D: Yep! 17>=12
The answer is either c or d. I would go with answer c though. sorry if it is wrong
Answer:
r = 9/sin Ф or r = 9 csc Ф
Step-by-step explanation:
The polar form is represented as:
x = r cos Ф and
y = r sin Ф
We are given:
y = 9
Putting value in y = r sin Ф
9 = r sin Ф
=> r = 9/sin Ф
1/sin Ф = csc Ф
or, r = 9 csc Ф
Answer:
It depends on how much sun the place receives, how much it is shaded. temperature in the area. Do you have solar panels, electric heat, gas? All these factors determine utility cost.
