A: 112
b: 3 seconds
c: f(3) = 256
d: 7 seconds
Answer:
6.7 seconds
Step-by-step explanation:
Let's calculate the maximum height covered by the object
Max height= U²Sin²tita/2g
Where g is acceleration due to gravity
Max height= 40²(sin90)²/(2*9.81)
Max height= 1600/19.62
Max height=81.55 m
Total max height= 30+81.55
Total max height= 111.55 m
Time t it will take to travel from the max height at acceleration of 4.9 m/s²
S= ut + ½at²
u= 0 at Mac height
S= 111.5 m
111.5 = ½(4.9)t²
223/4.9= t²
45.5= t²
6.745 seconds= t
6.7 seconds= t
Answer:
14.2%
Step-by-step explanation:
1. Find the new cost for Stock A:
2000x0.88=1760
2. Find the new cost for Stock B:
5720x0.85=4862
3. Find total sum of the original stocks:
2000+5720=7720
4. Find total sum of the new stocks:
1760+4862=6622
5. Find the decrease:
7720(1-x)=6622
Solve for x
x=14.2

Answer:
64.428
Step-by-step explanation:
well to find the mean we add all of the numbers up and then divide it by the amount of numbers in the sequence
so if we add all of the numbers up it will give us
451
then if we divide that by the number of numbers in the sequence which is 7 then that will leave us with
around 65 or exactly it would be
64.428
