5. To figure this out you must find when y = 0
-16t^2 = -200
t^2 = 12.5
Square root
t = 3.54 C
6.
Axis of symetry = -.5 (always a vertical line down vertex)
Vertex = (-.5, -6.5) (the minimum of the graph)
B
7. To find maximum height you must find the vertex
The maximum height is 549 feet after 5.75 seconds
C
9. Solve for X
x^2 = 1
Square root
X = plus or minus 1
A
Answer:
The answer to your question is:
m = length of the smaller bed = 17 ft
l = length of the larger bed = 25 ft
Step-by-step explanation:
Data
A1 + A2 = 914
A1 - A2 = 336
A1 = l²
A2 = m²
Process
l² + m² = 914
l² - m² = 336
l² = 336 + m²
(336 + m²) + m² = 914
336 + 2m² = 914
2m² = 914 - 336
2m² = 578
m² = 578 / 2
m² = 289
m = 17 ft
l² = 336 + 289
l² = 625
l = 25 ft
after 4 weeks:
.3*4= 1.2 saved
then it is doubled
1.2*2 = 2.40
8 weeks
he will have saved for 4 more weeks ( week 5 6 7 8)
4 * .3 = 1.2 saved
2.4 + 1.2 = 3.6 saved
then it is doubled
3.6 * 2 =7.20
he will have saved for 4 more weeks ( week 9, 10, 11, 12)
4 * .3 = 1.2 saved
7.2+ 1.20=8.40
then it is doubled
8.4*2 = 16.8
He will have 16.80 after 12 weeks
