Percent decrease : (original number - new number) / original number)...x 100
(13.00 - 7.50) / 13.00 = 5.5/13 = 0.42....x 100 = 42% decrease
This is a geometric progression pattern with the common ratio of negative 0.5.
The next three would be -0.5, followed by 0.25, followed by -0.125
Answer:
Step-by-step explanation:
<h3>Part A</h3>
<u>Solve the equation:</u>
- 6x² + 48x + 120 = 0
- x² + 8x + 20 = 0
- x² + 8x + 16 + 4 = 0
- (x + 4)² + 4 = 0
- (x + 4)² = - 4
The left side is positive and right side is negative so no solution
<h3>Part B</h3>
There is no intercession with the x-axis, the graph of the function is entirely above the x-axis.
It means the diver won't reach the bottom of the lake
46% is equal to 14/25
14/25 is equal to 46/100 (multiply 14/25 times 4/4) and that is 46%
