Determine whether the graph is that of a function by using the vertical-line test. If it is, use the graph to find (a) its domai
Ilia_Sergeevich [38]

Answer:

Following are the solution to this question:

Explanation:

If the draw a line perpendicular with y-axis thru the diagonal line check but it meets only one curved point, therefore the curve indicates a function not otherwise.  They draw a vertical line perpendicular to the y-axis there, it just intersects one more chart point, which is why a graph is a feature:

In point a:

\to Domain= [-\pi ,\pi ]\\\\\to Range = [-1,1]

In point b:

Its y-axis length cut also by understanding the benefits of y-interception and the x-axis length gives the x-intercept.  

\to y-intercept = 1\\\\\to x-intercept = \frac{\pi}{2} ,- \frac{\pi}{2} \\\\

In point C:

Every graph is y-axis symmetric because the left side of the column as well as the middle side of the graph is about the same.

The label on a bottle of medicine reads​ "Each 5 mL teaspoonful contains​ glucose, 1.87​ g; levulose, 1.87​ g; and phosphoric​ a
Alexandra [31]

(a) 43.6 mg; (b) 520 mg

(a) <em>Mass of phosphoric acid (PA) in a dose </em>

Mass of PA = 2 tsp × (21.8 mg PA/1 tsp) = 43.6 mg PA

(b) <em>Mass of PA in the bottle </em>

<em>Step 1</em>. Convert <em>ounces to millilitres </em>

Volume = 4 oz × (30 mL/1 oz) = 120 mL

<em>Step 2.</em> Calculate the mass of PA

Mass of PA = 120 mL × (21.8 mg PA/5 mL) ≈ 520 mg PA

A compound contains nitrogen and a metal. This compound goes through a combustion reaction such that compound X is produced from
tia_tia [17]

Answer:

The correct answer is: X is nitrogen dioxide, and Y is a metal oxide

Explanation:

Combustion of compound of containing nitrogen and metal will give nitrogen  dioxide and metal oxide as product. During combustion reaction a compound reacts with oxygen in order to yield oxides of elements present in the compound.

The general equation is given as:

4M_3N_x+7xO_2\rightarrow 4xNO_2+6M_2O_x

Hence, the correct answer is :X is nitrogen dioxide, and Y is a metal oxide.
