The code is given below:

number_of_days = 30

amount_after_30days = 0.01 * (2 ** number_of_days)

If a scalene triangle has its measures 4 m, 11 m and 8 m, find the largest angle.

soldier1979 [14.2K]

Answer:

129.8 approximately

Step-by-step explanation:

So this sounds like a problem for the Law of Cosines. The largest angle is always opposite the largest side in a triangle.

So 11 is the largest side so the angle opposite to it is what we are trying to find. Let's call that angle, X.

My math is case sensitive.

X is the angle opposite to the side x.

Law of cosines formula is:

$x^2=a^2+b^2-2ab \cos(X)$

So we are looking for X.

We know x=11, a=4, and b=8 (it didn't matter if you called b=4 and a=8).

$11^2=4^2+8^2-2(4)(8)\cos(X)$

$121=16+64-64\cos(X)$

$121=80-64\cos(X)$

Subtract 80 on both sides:

$121-80=-64\cos(X)$

$41=-64\cos(X)$

Divide both sides by -64:

$\frac{41}{-64}=\cos(X)$

Now do the inverse of cosine of both sides or just arccos( )

[these are same thing]

$\arccos(\frac{-41}{64})=X$

Time for the calculator:

X=129.8 approximately

Diana invested $3000 in a savings account for 3 years. She earned $450 in interest over that time period. What interest rate did

matrenka [14]

If I=P*r*t, we can input 450 in for I, 3000 in for the principal (P, or the starting rate), and 3 for t=time because there were three years, resulting in 450=9000*r. Next, we can divide both sides by 9000 to get 0.05 or 5% as our answer.

The lowest temperature ever recorded in North America was -63°C. The lowest temperature ever recorded in South America was –32.8

Snowcat [4.5K]

9514 1404 393

Answer:

warmer by 30.2 degrees

Step-by-step explanation:

It might help to think of these values plotted on a number line. Both temperatures will be left of zero, with -63°C being farther to the left (colder).

The difference can be found by subtracting the colder temperature from the warmer one:

-32.8 -(-63) = -32.8 +63 = 63 -32.8 = 30.2 . . . degrees

The South America temperature -32.8°C is 30.2° warmer than the North America temperature.
