Answer:
x = 240°, x = 300°
Step-by-step explanation:
Using the identity
sin x = 
= 
= - 
, then
x = 
( ) = 60° ← related acute angle
Since sin x < 0 then x is in 3rd / 4th quadrants
x = 180° + 60° = 240°
x = 360° - 60° = 300°
Answer:
The slope is zero. Since both coordinates have the y-value of -1, they are on the same line on the graph and form a horizontal line with a slope of zero. (a straight horizontal line)
Step-by-step explanation:
use the formula
(y2-y1)/(x2-x1)
to calculate the slope using 2 points
so where (x1,y1) (x2,y2) can be subsituted
so putting it in the formula ...
(-1-(-1))/(7-10)=
0/-3=0
Answer: What you should do is 27 tens divided by three tens.
Step-by-step explanation:
This is because imagine it was 27 divide by 3. That will be 9 so then you just multiply that by one thousand
Answer: See explanation
Step-by-step explanation:
You didn't give the options relating to the question.
To solve this first, you need to know that we have to note that (+) × (-) = (-). Therefore, 1.25+(-0.75) will be thesame as writing 1.25 - 0.75. This will then be:
= 1.25 - 0.75
= 0.50
Answer:
15/28 simplified to 5/8 (credit to other answer.)
Step-by-step explanation:
Multiply the top numbers 3*5 which equals 15 and then multiply the bottom numbers 4 and 7 for 28. Put 15 over 28.
