Answer:
- there are 4 complex solutions
- 3 real zeros and 2 complex zeros
Step-by-step explanation:
1. Descarte's rule of signs tells you there are 0 positive real roots and 0 or 2 negative real roots. (for positive x, signs are ++++ so have no changes; for negative x, signs are ++-+, so have 2 changes.) A graph shows no real roots.
2. There are 3 sign changes in the given polynomial, so 3 or 1 positive real roots. When the sign of x is changed, there are 2 sign changes, so 0 or 2 negative real roots. A graph shows 2 negative and one positive real root (for a total of 3), so the remaining 2 roots are complex.
You would use the tangent first, because the opposite of 40 would be x and the adjacent would be 30ft

solve for "x"
when taking the sine, make sure your calculator is in Degree mode, since the angle is in degrees, not radians
Answer:
B.) 6x² + 7x + 2
Step-by-step explanation:
(3x + 2) ( 2x + 1)
6x² + 3x + 4x + 2
<u>6x² + 7x + 2</u>
Answer:
The Greatest Common Factor, the GCF, is the biggest ("greatest") number that will divide into (that is, the largest number that is a factor of) both 2940 and 3150. On the other hand, the Least Common Multiple, the LCM, is the smallest ("least") number that both 2940 and 3150 will divide into.
Have a good day
