Answer:

Q(3\,min) = 0.349\,pd

Step-by-step explanation:

The expression for the salt in the barrel is:

Q(t) = 6\cdot (1-e^{-0.02\cdot t})

The quantity of salt in the barrel after 3 minutes is:

Q(3\,min) = 6\cdot [1-e^{-0.02\cdot (3\,min)}]

Q(3\,min) = 0.349\,pd

A volleyball reaches its maximum of 13 feet, 3 seconds after it is served. What quadratic formula could model the height of the
Katena32 [7]

Answer:

H=-(t-3)^2+13

Step-by-step explanation:

The path covered by the volleyball will be a downward parabola with the vertex being the highest point of the ball.

A general form of a downward parabola is given as:

y=-a(x-h)^2+k

Where (h,k) is the vertex of the parabola and 'a' is a constant.

Now, let 'h' be the vertical height and 't' be the time taken.

So, the equation would be of the form:

H=-a(t-h)^2+k

Now, as per question:

h = 2 seconds, k = 13 feet.

H=-a(t-3)^2+13

Now, taking a = 1. So, the formula that can be used is:

H=-(t-3)^2+13

What is X:<br> 3x−22=44<br> 5/6 = 10/2x−3
Rom4ik [11]

Answer:

x = 22

x = 4,6

Step-by-step explanation:

3x - 22 = 44

3x = 44 + 22

3x = 66

x = 66/3

x = 22

5/6 = 10/2x - 3

5/6 + 3 = 10/2x

5/6 + 18/6 = 10/2x

23/6 = 10/2x

23/6 * 2 = 10x

46 = 10x

x = 46/10

x = 4,6

5x + 1 = 6x - x<br> I need help on this problem may you help
schepotkina [342]

Answer:

Step 1: Simplify both sides of the equation.

5x+1=6x−x

5x+1=6x+−x

5x+1=(6x+−x)(Combine Like Terms)

5x+1=5x

5x+1=5x

Step 2: Subtract 5x from both sides.

5x+1−5x=5x−5x

1=0

Step 3: Subtract 1 from both sides.

1−1=0−1

0=−1

Answer:

There are no solutions.
