What conjecture can you make about the sum of the first 22 positive even numbers?
alekssr [168]

Answer:

A.) The sum of the product of the number of terms and the number of terms plus one.

Step-by-step explanation:

So, we have the sum of the first 22 positive even numbers:

S = 2 + 4+ 6 + ... + 44

We know the sum of such sequence is given by the (sum of the first number (2) and the last number (44)) multiplied by the number of terms (11).

S = (2 + 44) * 11 = 46 * 11 = 506

Answer A tells us it should be the sum of the number of terms (22) by the number of terms plus one (22 + 1 = 23).

S = 22 * 23 = 506

That's confirmed.

Answer B would give 22 * 21 = 462, so it's not right

Answer C would give 22 * 2 = 44, obviously not right

Answer D would give 22 * 22 = 484, close but not right.

Can someone solve this please?
Hunter-Best [27]

Answer:

3.16 units

Step-by-step explanation:

The distance between the points P1 (6, 8) and P2 (7, 5)) can be solved by using the distance formula given as d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}.

Let,

(6, 8) = (x_1, y_1)

(7, 5) = (x_2, y_2)

Plug these values into the distance formula.

Thus:

d = \sqrt{(7 - 6)^2 + (5 - 8)^2}

d = \sqrt{(1)^2 + (-3)^2}

d = \sqrt{1 + 9}

d = \sqrt{10} =

d = 3.16 (nearest tenth)

Distance between the two points in the graph is approximately 3.16 units
