Ket [755]3 years ago

Answer:

3\sqrt{5}

Step-by-step explanation:

View the distance as a hypotenuse of a triangle ΔABC (∠C = 90°).

Use Pythagorean theorem:

AB = y1 - y2 = 9 - 6 = 3

AC = x1 - x2 = 4 - (-2) = 6

Now calculate BC which is also the distance needed:

BC^{2} =AC^{2} +AB^{2}

BC^{2} = 6^{2} + 3^{2} = 45

BC = \sqrt{45} = \sqrt{3 * 3 * 5} (BC > 0)

BC = 3\sqrt{5}

Sav [38]

The total profit received for all mobile phone manufacturers for all carriers was 1.54 billion

Step-by-step explanation:

Given,

Profit received = 32%

Total profit received = $4.8 billion

Amount of profit received for mobiles = 32% of total profit

Amount received = \frac{32}{100}*4.8

Amount received = \frac{153.6}{100}

Amount received = 1.536 billion

Rounding off

Amount received = 1.54 billion

The total profit received for all mobile phone manufacturers for all carriers was 1.54 billion

Write the equation of the line from the given information. slope 1/2, through (4,-3)
wariber [46]

Answer:

y+3 = 1/2 (x-4)

Step-by-step explanation:

We can write the equation in point slope form

y-y1 = m(x-x1)

The slope is m and the point is (x1,y1)

y - -3 = 1/2(x -4)

y+3 = 1/2 (x-4)
