In which quadrant is the number –14 – 5i located on the complex plane?

answer:   $5.10

step-by-step explanation:

change 15% into a decimal >   0.15

multiply 0.15 and 33.99

33.99 x 0.15 = 5.0985

in this situation were the answer is in money my teacher would make me round so the answer would be 5.10 so i would say the answer is $5.10

i hope this : )

the first triangle is larger

step-by-step explanation:

(1/2)(8)(10)=40

(1/2)(5)(13)=32.5

answer:

it is true, because the cosine function has a period of 2π

step-by-step explanation:

since, the period of the cos function is 360° ( or 2π radians ), it holds the property of:

taking as , is equal to  

the equation is true!

note: the cos function is even function

hence, the equation is true, because the cosine function has a period of 2π, not because the cosine function is odd, which it is
