Westkost [7]3 years ago
5 0

Answer:

(4 + 5i)(2 - 7i) = 8 - 28i + 10i + 35

= 43 - 18i

4 + 5i(2 - 7i) = 4 + 10i + 35

= 39 + 10i

Find the rate of change between (-3,6) (0,-3)
marin [14]
<h3>The rate of change between (-3,6) (0,-3) is -3</h3>

<em><u>Solution:</u></em>

Given that,

We have to find the rate of change between (-3,6) (0,-3)

<em><u>The rate of change is given as:</u></em>

Rate\ of\ change = \frac{y_2-y_1}{x_2-x_1}

From given,

(x_1, y_1) = (-3, 6)\\\\(x_2, y_2) = (0, -3)

<em><u>Substituting the values we get,</u></em>

Rate\ of\ change = \frac{-3-6}{0+3}\\\\Rate\ of\ change = \frac{-9}{3}\\\\Rate\ of\ change = -3

Thus rate of change is -3

nalin [4]

Answer: Option C

Step-by-step explanation:

In group(1), the risk is= 5/2000 x 100

                          = 0.25

In group(2), the risk is= 5/1000 x 100

                         = 0.5

The sample relative risk is= 0.25/0.5

                                          = 0.5

So, option C is correct.

The equation $x + {y = 2 can be rewritten in a form that reveals the y-intercept of the graph of the equatior
SSSSS [86.1K]

Answer:

y = \frac{2}{z} - \frac{x}{z}

Step-by-step explanation:

Given

x + zy = 2

Required

Rewrite to show y-intercept

We have: x + zy = 2

Subtract x from both sides

zy = 2-x

Divide both sides by z

y = \frac{2}{z} - \frac{x}{z}

<em>The y intercet is: </em>\frac{2}{z}<em></em>
