In a famous story, a wise man in India requests a reward promised by his king. The wise man shows the king a chessboard having 6

4 squares. "Put 1 grain of rice on the first square, 2 grains on the second square, 4 on the third square, 8 on the fourth square, and so on, doubling the number of grains each time, until all 64 squares are filled with the right number of grains. That will be my reward." How many rice grains must be given in total ?

So you probably wonder how many grains it would take about (2^63 + 1 ) 2
18 x 10^18 grains of rice

You do remember the end of the story?

Find the slope of the line that passes through:<br> (-4,7) and (-6, -4)
Yuri [45]

Answer:

\frac{11}{2} or 5.5

Step-by-step explanation:

In order to find the slope of a line using two points on a graph, you must use

y_2-y_1/x_2-x_1

Pluging in the points (-4,7) and (-6, -4) to the formula you will get:

\frac{-4-7}{-6+4} =\frac{-11}{-2} =5.5

The equation for the line would be \frac{11}{2}x+29

Use the distance formula to find the perimeter. Round to the nearest tenth.
Ierofanga [76]

Answer:

37.6 units

Step-by-step explanation:

Perimeter = sum of all sides of the triangle

To find the sum, find the distance between each points.

✔️Distance between points (-7, 6) and (5, -4):

d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} =

= \sqrt{(5 - (-7))^2 + (-4 - 6)^2}

= \sqrt{(12)^2 + (-10)^2}

= \sqrt{144 + 100}

= \sqrt{244} = 15.6 units (nearest tenth)

✔️Distance between (-7, 6) and (-7, -4):

|6 -(-4)| = 10 units

✔️Distance between (-7, -4) and (5, -4)

|-7 - 5| = 12 units

✔️ Perimeter = 15.6 + 10 + 12 = 37.6 units

What is the positive angle less than 2π that is coterminal with 14π/6
Dahasolnce [82]

Coterminal angles are angles that are made by the positive x-axis of the coordinate plane. The positive angle that is less than 2π and is coterminal with 14π/6 is  1/3π.

<h3>What are coterminal angles?</h3>

Coterminal angles are angles that are made by the positive x-axis of the coordinate plane.

The angle that 14π/6 makes from the positive x-axis is 1/3π, which is equal to 60°.

Hence, the positive angle that is less than 2π and is coterminal with 14π/6 is  1/3π.
