What is the inequality?

Mathematics
1 answer:
crimeas [40]3 years ago
6 0

Answer:

y\leq \frac{1}{2}x+2

Step-by-step explanation:

we know that

The solution of the inequality is the shaded area below the solid line (the inequality is of the form y\leq mx+b)

The y-intercept of the solid line is (0,2)

The x-intercept of the solid line is (-4,0)

The slope of the solid line is

m=(0-2)/(-4-0)=\frac{1}{2}

The equation of the solid line is y=\frac{1}{2}x+2

therefore

The linear inequality represented by the graph is

y\leq \frac{1}{2}x+2

White raven [17]

Answer:

40\ \text{inches}

Step-by-step explanation:

\theta = Angle = 5.7^{\circ}

Let the vertical distance be is y=4\ \text{inches}

horizontal distance be x

So, slope is the tangent of the angle between the vertical and horizontal

\dfrac{y}{x}=\tan\theta\\\Rightarrow \tan5.7^{\circ}=\dfrac{4}{x}\\\Rightarrow x=\dfrac{4}{\tan5.7^{\circ}}\\\Rightarrow x=40.07\approx 40\ \text{inches}

The horizontal distance for flared sides is 40\ \text{inches}.

A prescription calls for the following: Sodium citrate 5 g Tartar Emetic 0.015 g Cherry syrup ad 120 mL Using a balance with a s
ella [17]

Answer:

measure the volume of cherry syrup solution with Tartar Emetic = 22.5 mL

Hence, the correct quantity of tartar emetic to fill the prescription will be obtained

Step-by-step explanation:

Given:

Mass of Sodium citrate = 5 g

Mass of Tartar Emetic = 0.015 g = 15 mg

Volume of Cherry syrup ad 120 mL = 120 mL

sensitivity = 4 mg

Error = 5%

Now,

The smallest weight that can be measured = \frac{\textup{Sensitivity}}{\textup{Error}}\times100

or

The smallest weight that can be measured =  \frac{\textup{4}}{\textup{5}}\times100  = 80 mg

Now,

80 mg is dissolved in 120 mL of Cherry syrup according to prescription

( Thus,

1 mg is dissolved in \frac{120}{80}\ mL  of Cherry syrup according to prescription )

so to measure 15 mg of Tartar Emetic, measure the volume of cherry syrup

=   15\times\frac{120}{80}\ mL

= 22.5 mL

Hence, the correct quantity of tartar emetic to fill the prescription will be obtained
