Point G is the centroid of the right △ABC with m∠C=90° and m∠B=30°. Find AG if CG=4 ft.

o-na [289]

Answer: $\text{Length of AG=}\frac{2\sqrt{63}}{3}$

Explanation:

Please follow the diagram in attachment.

As we know median from vertex C to hypotenuse is CM

$\therefore CM=\frac{1}{2}AB$

We are given length of CG=4

Median divide by centroid 2:1

CG:GM=2:1

Where, CG=4

$\therefore GM=2$ ft

Length of CM=4+2= 6 ft

$\therefore CM=\frac{1}{2}AB\Rightarrow AB=12$

In $\triangle ABC, \angle C=90^0$

Using trigonometry ratio identities

$AC=AB\sin 30^0\Rightarrow AC=6$ ft

$BC=AB\cos 30^0\Rightarrow BC=6\sqrt{3}$ ft

$CN=\frac{1}{2}BC\Rightarrow CN=3\sqrt{3}$ ft

In $\triangle CAN, \angle C=90^0$

Using pythagoreous theorem

$AN=\sqrt{6^2+(3\sqrt{3})^2\Rightarrow \sqrt{63}$

Length of AG=2/3 AN

$\text{Length of AG=}\frac{2\sqrt{63}}{3}$ ft

What is the greatest measure of length? A. 5,000 meters B. 6,000 centimeters C. 30,000 millimeters D. 1 kilometer

Bess [88]

Answer: A. 5,000 meters

Step-by-step explanation:

Starting with the smallest unit which is option C. There are 10 millimeters in one centimetre. Option c in centimeters is:

= 30,000 / 10

= 3,000 meters.

Option c is smaller than B and so is incorrect.

A meter is 100 centimeters. Option b in meters is;

= 6,000 / 100

= 60 meters

This is less than option A so is incorrect.

A kilometer is 1,000 meters so option A in meters is:

= 5,000 / 1,000

= 5 kilometers

This is higher than option d so option A is correct.

14 divided by 5 turned into a mixed number

Scrat [10]

14 divided by 5 is 2.8 and 2.8 you can change 2.8 to 28/10 simplify that to 14/5 and turn it to a mixed number you get 2 4/8

After having been on the air for more than a decade, Fox's American Idol seemed to be suffering from viewer fatigue. The average

ElenaW [278]

Answer:

a) In the first season, there were 25.450 million viewers.

b) In the fourth season, the number of viewers was 11.950 million.

Step-by-step explanation:

Hi there!

The average number of viewers in season t is given by the following function:

$f(t) = 32.744 e^{-0.252t}$

a) To obtain the average number of viewers in season 1, we have to evaluate the function at t = 1:

$f(1) = 32.744e^{-0.252 (1)} = 25.450$

In the first season, there were 25.450 million viewers.

b) Now we have to evaluate the function at t = 4:

$f(4) = 32.744e^{-0.252(4)} = 11.950$

In the fourth season, the number of viewers was 11.950 million.
