Step-by-step explanation:
the answer is D: Both 3 and 4
Answer:
Step-by-step explanation:
During the first year, ABC's stock price starts at $100 and increases by 100%. This means that the amount by which the stock increased would be
100/100 × 100 = $100
The new price of the stock would be 100 + 100 = $200
During the second year, its stock price goes down 25% from its price at the end of the first year. This means that the amount by which the stock reduced is
25/100 × 200 = 0.25 × 200 = $50
Therefore, the price of the stock, in dollars, at the end of the second year is
200 - 50 = $150
Answer:
111.65
Step-by-step explanation:
$15.25 x 3 = $45.75
$32.95 x 2 = $65.9
Total: $111.65
Sec^2 x - 1 = tan^2x
Proof:
Sec^2x = 1+ tan^2x
1/cos^2x = 1 + sin^2x/cos^2x
<span>1/cos^2x - sin^2x/cos^2x = 1
</span>Using common denominator:
(1-sin^2x)/cos^2x = 1
sin^2x + cos^2 x = 1
cos^2 x = 1 - sin^2x
Substituting :
cos^2x/<span>cos^2x = 1
</span>1 = 1
Left hand side = right hand side
