A:
1) Use difference of squares:
2) Use difference of squares:
B:
1) Factor out common terms in the first two terms, then in the last two terms.
Factor out the common term y-1
C:
1) Collect like terms
2) Simplify.
D:
a3 – a2 – ab + a + b – 1
= a3 – a2 – ab + b + a – 1
= a2 (a – 1) – b (a – 1) + 1 (a – 1)
= (a – 1) (a2 – b + 1)
Answer:
3(x32+12)
Step-by-step explanation:
Answer:
y = 1/2sin(x) - 2
Step-by-step explanation:
Since 2 is subtracted from the end of the function, the graph will be shifted down 2 units. The parent function y = sin(x) goes through the origin, (0, 0); this means the y-intercept of this graph will be at (0, -2).
Additionally, since the function has been stretched horizontally, we know it has been multiplied by a fraction. This means it must be y = 1/2sin(x) - 2.
Equals to. As 0.60 could also be written as 0.6 or 0.600 ( the difference would be the amount of decimals but the value is the same )
Angle 1
=180-62.8
=117.2
Angle 2
=180-117.2
=62.8
