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:432
Step-by-step explanation: 12·3=x
36·12=x
x=432
A.
add 12 to both sides the divide 8 by both sides and there is the answer to x
First find the slope of the equation you are given
5x-4y=10
-4y=-5x+10
y=5/4x+10
So your slope is 5/4
Parallel lines have the same slope so the slope of line q is 5/4
Now use the point-slope formula to find the equation
y-(-7)=5/4(x-12)
y+7=5/4x-60/4
y+7=5/4x-15
y=5/4x-8
Line q’s equation is y=5/4x-8
Undoubtedly this will be represented by a LINEAR FUNCTION
The function mentioned is:
P(x) = 10 + 0.75 x
where P(x) is the Function Pricing
x refers to the miles
This function is classified as Linear Function (f(x) = ax + b and is represented by a line
