The graph shows the amount of a medicine min milligrams, remaining in a patient's body hours after receiving an injection . The

aksik [14]

An exponential function is a function defined by y = ab^x, where a represents the initial value, and b represents the rate

<h3>(a) The factor at which the medicine decreased, in 1.5 hour</h3>

From the graph, we have the following ordered pairs

(x,y) = (0,270) and (1.5,80)

Given that:

$y = ab^x$

At point (0,270), we have:

$ab^0=270$

$a= 270$

At point (1.5,80), we have:

$ab^{1.5} = 80$

Substitute 270 for a

$270b^{1.5} = 80$

Divide both sides by 270

$b^{1.5} = 0.2963$

Take 1.5th root of both sides

$b =0.44$

Hence, the medicine decrease in the hour and half at a factor of 0.44

<h3>(b) The factor at which the medicine decreased in the first half hour, and the first hour</h3>

In (a), we have:

The decay factor (b) to be 0.44

This represents the factor at which the medicine decreased throughout.

Hence, the medicine decrease in the first half hour, and the first hour at a factor of 0.44

<h3>(c) The exponential equation</h3>

In (a), we have:

$a= 270$

$b = 0.44$

So, the exponential equation is:

$y =270 * 0.44^x$

In terms of m and h, we have:

$m =270 * 0.44^h$

Hence, the equation relating m to h is $m =270 * 0.44^h$

M(6, 7) is the midpoint of RS. The coordinates of 5 are (8,9). What are the coordinates of R?

Marta_Voda [28]

Answer:

R=(4,5)

Step-by-step explanation:

M={x1+x2/2,y1+y2/2}

(6,7)={8+x2/2,9+y2/2}

Equating the x coordinates and y coordinates

6=8+x2/2

12=8+x2

x2=12-8=4

7=9+y2/2

14=9+y2

y2=14-9=5

Identify the property used in each step of solving the inequality 3x-2>-4.

WARRIOR [948]

Addition property of equality

Division property of equality

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

<em><u>Given inequality is:</u></em>

3x - 2 > 4

$\mathrm{Add\:}2\mathrm{\:to\:both\:sides}$

Here, Addition property of equality is used

When the same amount is added to both sides of an inequality, then the inequality is still true

3x - 2 + 2 > 4 + 2

3x > 6

$\mathrm{Divide\:both\:sides\:by\:}3$

Here, Division property of equality is used

When we divide both sides of an equation by the same nonzero number, the sides remain equal.

$\frac{3x}{3}>\frac{6}{3}\\\\x > 2$

Thus the property used in each step of solving the inequality is found
