Answer:
29
Step-by-step explanation:
(1.2 x 10-4) + (2.4 x 10-3)
Simplify
1.2 x 10- 4 = 8
2.4 x 10- 3 = 21
Add both sums to get 29!
SCIENTIFIC NOTATION
2.9 x 10 to the 1st power
Move the decimal over to make a number less than ten, so that makes 2.9 and 10 to the 1st because you moved the decimal once! Hope this is better
7.5 i believe. not very good at math tho lol
Answer: cos²(θ) + sin(θ)sin(e)
<u>Step-by-step explanation:</u>
sin (90° - θ)cos(Ф) - sin(180° + θ) sin(e)
Note the following identities:
sin (90° - θ) = cos(x)
sin (180° + θ) = -sin(x)
Substitute those identities into the expression:
cos(x)cos(x) - -sin(x)sin(e)
= cos²(x) + sin(x)sin(e)
