Answer:
The zeros are x=1, x=-6
Step-by-step explanation:
f(x) =x^2+5x-6
Factor: What two numbers multiply to -6 and add to 5
-1 *6 = -6
-1 +6 = 5
f(x) = (x-1) (x+6)
Using the zero product property
0 = (x-1) (x+6)
x-1 =0 x+6=0
x=1 x=-6
The zeros are x=1, x=-6
Answer:
32%
Step-by-step explanation:
165/125=1.32
percent change would be 32% because when you add 32 to 100 then divide by 100, you will get the 1.32. and 1.32 is the change in 125 and 165. you would multiply 125 by 1.32 to get 165.
cos(a - b) - cos(a + b) = 2sin(a)sin(b)
[cos(a)cos(b) + sin(a)sin(b)] - [cos(a)cos(b) - sin(a)sin(b)] = 2sin(a)sin(b)
[cos(a)cos(b) - cos(a)cos(b)] + [sin(a)sin(b) + sin(a)sin(b)] = 2sin(a)sin(b)
2sin(a)sin(b) = 2sin(a)sin(b)
For number 4 subtract 32.56 - 29.40 and the answer should be 3.16.
