Simplify the expression. (0.4x10^-6)(0.7x10^-2)

Mathematics
1 answer:

Answer:

2.8 ·  10^(-9)

Step-by-step explanation:

I'd suggest you do this problem through two separate multiplications:

First, 0.4·0.7 = 0.28, or 2.8 · 10^(-1)

Second, 10^(-6) · 10^(-2) = 10^(-8), and so the final result is

2.8 · 10^(-1) · 10(-8)  =  2.8 ·  10^(-9)

Please note:  negative exponents (such as -9, above) should be enclosed in parentheses for added clarity.

Pls help :Find the missing side or angle.<br> Round to the nearest tenth.
Nitella [24]

Answer:

C° = 71.6056

Step-by-step explanation:

Law of Cosines: c² = a² + b² - 2abcosC°

Step 1: Plug in known variables

29² = 30² + 15² - 2(30)(15)cosC°

Step 2: Evaluate

841 = 900 + 225 - 900cosC°

-59 = 225 - 900cosC°

-284 = -900cosC°

71/225 = cosC°

cos⁻¹(71/225) = C°

C° = 71.6056

And we have our answer!
