Step-by-step explanation:
1)
Prime factors of 1225 : 5x5x7x7
Prime factors of 1024: 2x2x2x2x2x2x2x2x2x2
2)
We know that
Applying radical rule:
So,
3)
It can be written as:
Evaluating we get
4)
Put value of x, y and z in equation and solve:
So,
5)
We know (-a)^n = (a)^n when n is even and (-a)^n = (-a)^n when n is odd
So,
Answer: It should equal this ,-2+49÷(-7)=-9 !
Step-by-step explanation:
answer: y= 2x^2+2x-4
steps:
y= (2x+4)(x-1)
*FOIL method* y= (2x^2-2x+4x-4)
*simplify* y= 2x^2+2x-4
For this case we have the following equation:
sin (40o) = b / 20
Clearing b we have:
20 * sin (40o) = b
Therefore, the length of the AC segment is given by:
b = 12.9
Answer:
the length of AC is:
b = 12.9
