The answer is 21 which comes from 7 * 3.

Draw the four points in a complex plane. From the drawing you can see that the lenght is 4i - (-3i) = 4i + 3i = 7i, and the width is 1 - (-2) = 1 + 2 = 3.

So, the area is 7 * 3 = 21.

In ABC, the sum of the measures of Angle A and angle B is 47°. What is the measure of Angle C ?

puteri [66]

Answer:

∠ C = 133°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180° , that is

∠ A + ∠ B + ∠ C = 180° ( substitute A + B = 47° )

47° + ∠ C = 180° ( subtract 47° from both sides )

∠ C = 133°

gtnhenbr [62]

Answer:

$Domain\ =\ \{x: 9,10,11....16\}$

$Range\ =\ \{y:290, 315,340.....465\}$

Step-by-step explanation:

Given

$y = 25x + 65$

Required

Determine the range and domain when x = 9 to 16

The domain is the set of

$Domain\ =\ \{x: 9,10,11....16\}$

Solving for the range;

When x = 9

$y = 25 * 9 + 65$

$y = 225 + 65$

$y = 290$

When x = 10

$y = 25 * 10 + 65$

$y = 250 + 65$

$y = 315$

When x = 11

$y = 25 * 11 + 65$

$y = 275 + 65$

$y = 340$

You continue till you get to x = 16

---

--

-

When x = 16

$y = 25 * 16 + 65$

$y = 400 + 65$

$y = 465$

Hence; the range is

$Range\ =\ \{y:290, 315,340.....465\}$
