Answer:
19. D
20. A
Step-by-step explanation:
19. Tan= opp/adj
20. Sin= opp/hyp
2/5(x - 1) < 3/5(1 + x)
To find the solution, we can use the distributive property to simplify.
2/5x - 2/5 < 3/5 + 3/5x
Multiply all terms by 5.
2x - 2 < 3 + 3x
Subtract 2x from both sides.
-2 < 3 + x
Subtract 3 from both sides.
-5 < x
<h3><u>The value of x is greater than the value of -5.</u></h3>
Answer:
D. 3.5
Step-by-step explanation:
28 divided by 8 = 3.5
3 in the power of ten means "10^3."

How to solve exponents is to multiply the number as many times as it's exponent. So in this case you will have to multiply ten, three times.

Which would mean that....

The answer is 10^3.
Hope this helps.
