4 0

Answer:

The answer to your question is dAB = \sqrt{8}

Step-by-step explanation:

Data

A (-6, 4)

B (-8, 6)

Process

To solve this problem, just use the formula of the distance between to points, substitute the values, simplify and get the answer.

dAB = \sqrt{(x2 - x1)^{2} + (y2 - y1)^{2}}

x1 = -6    y1 = 4    x2 = -8   y2 = 6

-Substitution

dAB = \sqrt{(-8 + 6)^{2} + (6 - 4)^{2}}

-Simplification

dAB = \sqrt{(-2)^{2} + (2)^{2}}

dAB = \sqrt{4 + 4}

-Result

dAB = \sqrt{8}

Answer:

1806 seats.

Step-by-step explanation:

From the question given above, the following data were obtained:

Row 1 = 24 seats

Row 2 = 27 seats

Row 3 = 30 seats

Total roll = 28

Total number of seat =?

From the above data, we can liken the roll to be in arithmetic progress.

Also, we are asked to determine the total number of seats in the theater.

Thus the sum of the sequence can be written as:

Roll 1 + Roll 2 + Roll 3 +... + Roll 28 i.e

24 + 27 + 30 +...

Thus, we can obtain obtained the total number of seats in the theater by applying the sum of arithmetic progress formula. This can be obtained as follow:

First term (a) = 24

Common difference (d) = 2nd term – 1st term

Common difference (d) = 27 – 24 = 3

Number of term (n) = 28

Sum of the 28th term (S₂₈) =?

Sₙ = n/2 [2a + (n –1)d]

S₂₈ = 28/2 [2×24 + (28 –1)3]

S₂₈ = 14 [48 + 27×3]

S₂₈ = 14 [48 + 81]

S₂₈ = 14 [129]

S₂₈ = 1806

Thus, the number of seats in the theater is 1806.

Solve the following question algebraically, show your work<br><br> 13 + w/7 &lt;-(fraction) = -18
evablogger [386]

Solve for w: by simplifying both sides of the equation, then isolating the variable.

w=-217

Work: 1.  Subtract 13 from both sides (w/7 = -18 - 13), 2.Simplify -18-13 to -31 (w/​7=-31), 3.Multiply both sides by 7 (w = -31 * 7), 4. Simplify 31*7 to 217 (w=-217)
