Answer:
6.81s
Step-by-step explanation:
First you must know that the velocity of the body is zero at the maximum height.
v =dy/dx
v= -32x+218
Since v = 0
-32x+218 =0
32x =218
x= 218/32
x = 6.81s
Hence the rocket reaches its maximum height after 6.81s
Answer:
5
Step-by-step explanation:
each daughter has 2 sisters and 2 brothers but each son had 1 brother and 3 sisters
3(4 - 2x) + 3x 12 + 3x 12 + 6x 12 - 3x 12 - 9x
12 - 6x + 3 • 12 + 3 • 12 + 6 • 12 - 3 • 12 - 9x
12 - 6x + 36 + 36 + 72 - 26 - 9x
-9x - 6x + 12 + 36 + 36 + 72 - 26
-15x + 156 - 26
-15x + 130
Answer:
600
Step-by-step explanation:
this is because it is in the hundreds place so it has 6 hundres or in other words 600
The relative frequency of students who are not seniors at this high school will be 82.96%.
<h3>How to find how much percent 'a' is of 'b'?</h3>
Suppose a number is 'a'
Suppose another number is 'b'
We want to know how much percent of 'b' is 'a'.
Then, it is calculated as:
P = a/b × 100
A local high school has 1,203 students with 367 freshmen, 382 sophomores, 249 juniors, and 205 seniors.
Then the relative frequency of students who are not seniors at this high school will be
P = 998/1203 × 100
P = 0.82959 × 100
P = 82.959%
P ≈ 82.96%
