Answer:
See below (along with unit circle attached)
Step-by-step explanation:
It really helps to use the unit circle! I've attached it below for your convenience. Keep in mind that a point on the unit circle is defined by where is measured in radians.
Answer:
Step-by-step explanation:
The given expression is:
We multiply by the reciprocal of the second fraction:
We cancel out the common factors to get;
, where and
We simplify to get:
Answer:
(2x - 5) • (x + 3)
Step-by-step explanation:
Step-1 : Multiply the coefficient of the first term by the constant 2 • -15 = -30
Step-2 : Find two factors of -30 whose sum equals the coefficient of the middle term, which is 1 .
-30 + 1 = -29
-15 + 2 = -13
-10 + 3 = -7
-6 + 5 = -1
-5 + 6 = 1 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -5 and 6
2x2 - 5x + 6x - 15
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (2x-5)
Add up the last 2 terms, pulling out common factors :
3 • (2x-5)
Step-5 : Add up the four terms of step 4 :
(x+3) • (2x-5)
Which is the desired factorization
Final result :
(2x - 5) • (x + 3)
When rounding a number, the digit of the number can be increased up to 1, but the digit won't be decreased. So, it is possible to round a five digit number into six digit number. But to increase the number digit, the number should be rounded up. To be rounded up, a number should have value 5 or more.
