Answer:
Think about what number you got multiply 7 to get 28. Once you do, multiply the other numbers by that digit
Step-by-step explanation:
We know that
sin²x+cos²x=1
so
clear cos x
cos x=(+/-)√[1-sin²x]
in this problem
<span>Angle 0 is in quadrant 1 -----> cos o and sin o are positive
</span>sin o=2/5
cos x=√[1-(2/5)²]----> cos o=√[1-4/25]----> cos o=√[21/25]---> cos o=√21/5
the answer is
cos o=√21/5
Answer:
1. You first have to find the slope
2. Next, you have to find the y-intercept
3. Finally, you have to put it in y = mx + b form.
Step-by-step explanation:
The slope of 2 points is; 
The y-intercept is; 
y = mx + b
m is always the slope
b is always the starting point or y-intercept
3ab...when a = 2 and b = 3
(3)(2)(3) = 6(3) = 18
12z^2 - 7z -12/ 3z^2 + 2z - 8
= (4z+3) (3z -4)/ (z+2)(3z -4)
= (4z + 3) / (x+2)
Hope this helps
