Answer:

132 degrees

Step-by-step explanation:

1. Find the third angle of the triangle

All the degrees in a triangle up to 180, so subtract 73 and 59 from 180.

180 - 73 - 59 = 48

48 degrees is the measure of the third angle

2. To find the ?, you must know that a straight line has an angle of 180 degrees. Therefore, 180 = 48 + ?

Subtract to get the answer: 132 degrees

If 6 teenagers can drink 6 ice cream sodas in 2 minutes. how many ice cream sodas can the same 6 teenagers drink in 2 hours

san4es73 [151]

Not sure if I’m correct, but 360 because I’m 1 minute they can drink 3 ice cream sodas, so multiply 3 by 60, the 60 is supposed to be 60 minutes, once you get that amount that you multiplied (180) add it again (180+180) the total should be your answer.

What are the sine cosine and tangent of theta=7pi/4 radians

FrozenT [24]

Answer:

see explanation

Step-by-step explanation:

$\frac{7\pi }{4}$ is in the fourth quadrant

Where sin and tan are < 0 , cos > 0

The related acute angle is 2π - $\frac{7\pi }{4}$ = $\frac{\pi }{4}$

Hence

sin([ $\frac{7\pi }{4}$ ) = - sin( $\frac{\pi }{4}$ ) = - $\frac{1}{\sqrt{2} }$ = - $\frac{\sqrt{2} }{2}$

cos( $\frac{7\pi }{4}$ ) = cos( $\frac{\pi }{4}$ ) = $\frac{\sqrt{2} }{2}$

tan( $\frac{7\pi }{4}$ = - tan( $\frac{\pi }{4}$ = - 1

After an antibiotic tablet is taken, the concentration of the antibiotic in the bloodstream is modelled by the function C(t)=8(e

Alexxx [7]

Answer:

the maximum concentration of the antibiotic during the first 12 hours is 1.185 $\mu g/mL$ at t= 2 hours.

Step-by-step explanation:

We are given the following information:

After an antibiotic tablet is taken, the concentration of the antibiotic in the bloodstream is modeled by the function where the time t is measured in hours and C is measured in $\mu g/mL$

$C(t) = 8(e^{(-0.4t)}-e^{(-0.6t)})$

Thus, we are given the time interval [0,12] for t.

We can apply the first derivative test, to know the absolute maximum value because we have a closed interval for t.
The first derivative test focusing on a particular point. If the function switches or changes from increasing to decreasing at the point, then the function will achieve a highest value at that point.

First, we differentiate C(t) with respect to t, to get,

$\frac{d(C(t))}{dt} = 8(-0.4e^{(-0.4t)}+ 0.6e^{(-0.6t)})$

Equating the first derivative to zero, we get,

$\frac{d(C(t))}{dt} = 0\\\\8(-0.4e^{(-0.4t)}+ 0.6e^{(-0.6t)}) = 0$

Solving, we get,

$8(-0.4e^{(-0.4t)}+ 0.6e^{(-0.6t)}) = 0\\\displaystyle\frac{e^{-0.4}}{e^{-0.6}} = \frac{0.6}{0.4}\\\\e^{0.2t} = 1.5\\\\t = \frac{ln(1.5)}{0.2}\\\\t \approx 2$
