Ok so I have math homework and I need so help ASAP I need to find the average of 35 40 12 16 25 and 10 so could someone plz plz

Answer: 23! Add your numbers, and divide that sum by the amount of numbers added to get average!

Step-by-step explanation:

The average is found by adding all numbers of the sample, and diving by the amount of numbers added. For example:

The average of 1, 2, and 3. You first add 1 + 2 + 3 to get 6.

You then divide 6 by the number of numbers added, being 3 (1, 2, and 3.).

6 / 3 = 2. The average of 1, 2, and 3 is 2.

In your case, you have 35, 40, 12, 16, 25, and 10.

First you add 35 + 40 + 12 + 16 + 25 + 10 to get 138.

Then you divide 138 by the amount of numbers you added: 6.

138 divided by 6 = 23 (138/6).

Hope this helps!

Add your numbers, and divide that sum by the amount of numbers added to get average!

Nina [5.8K]

Step-by-step explanation:

For a quadratic equation y = ax² + bx + c, the vertex (the maximum or minimum point) is at x = -b/(2a).

1) y = -0.5t² + 2t + 38

The maximum is at:

t = -2 / (2 × -0.5)

t = 2

The maximum height is:

y = -0.5(2)² + 2(2) + 38

y = 40

The coordinates of the vertex are (2, 40).  That means the missile reaches a maximum height of 40 km after 2 minutes.

2) y = -4.9t² + 12t + 1.6

The maximum is at:

t = -12 / (2 × -4.9)

t = 1.22

The maximum height is:

y = -4.9(1.22)² + 12(1.22) + 1.6

y = 8.95

The coordinates of the vertex are (1.22, 8.95).  That means the missile reaches a maximum height of 8.95 m after 1.22 seconds.

3) y = -0.04x² + 0.88x

The maximum is at:

x = -0.88 / (2 × -0.04)

x = 11

The maximum height is:

y = -0.04(11)² + 0.88(11)

y = 4.84

The maximum height of the tunnel is 4.84 meters.

The maximum width is when y = 0.

0 = -0.04x² + 0.88x

0 = -0.04x (x − 22)

x = 22

The maximum width is 22 feet.
