Anyone here able to lend a helping hand?

Answer:

Step-by-step explanation:

1). Vertical intercept of the graph = Point at which the graph intersects the y-axis.

Therefore, vertical intercept is y = 1000.

In this situation vertical intercept means the initial dose of the drug taken = 1000 mg.

2). From the graph attached, point (x, y) represents,

x = Time 't' or duration

y = concentration of the drug after time 't'

Point (0, 1000) represents concentration = 1000 mg of the drug after t = 0 hour

Similarly, (1, 750) represents concentration = 750 mg after t = 1 hour

Therefore, fraction of drug remained = $\frac{750}{1000}$

= $\frac{3}{4}$

3). Let the equation, representing the concentration of the drug and time is,

$y=a(b)^t$

Here, a = Initial amount of the drug (at t = 0 hours)

= 1000 mg

At (t = 1 hours), concentration of the drug = 750 mg

$y=1000(b)^t$

$750=1000(b)^1$

$b=\frac{750}{1000}$

$b=\frac{3}{4}$

Therefore, equation will be,

$y=1000(\frac{3}{4})^t$

Find the three angles of a triangle if the sum of the first angle and twice the second equals the third and, and if four times t

Anna71 [15]

Answer:

First Angle = 45°

Second Angle = 30°

Third Angle = 105°

Step-by-step explanation:

First angle + 2(Second angle ) = Third Angle

4(second angle) = Third Angle + 15°

or, Third angle = 4(second angle) - 15° ...(1)

⇒First angle + 2(Second angle ) = 4(second angle) - 15°

or, First angle = 2(second angle) - 15° ... (2)

Now by ANGLE SUM PROPERTY of a triangle:

First angle+ Second angle + Third Angle = 180°

Now, putting the values of (1) , (2) in above expression,

{2(Second angle) - 15° } + Second angle +{ 4(second angle) - 15°} = 180°

is the required equation.

or, 7(Second angle) - 30° = 180°

or, 7(Second angle) = 30° + 180° = 210°

⇒ Second angle = 210°/ 7 = 30°

Now, First angle = 2(second angle) - 15°

= (2 x 30°) - 15° = 45°

and, Third angle = 4(second angle) - 15°

= 4 x 30° - 15° = 120 - 15° = 105°
