There are 2 ways of measuring angle. It is either by radians or by degree. Radians is unitless or we just call it rad. A pi is equivalent to 180 degrees. A pi is equal to 3.14. So when we answer this we multiply 216 by pi/180 or 2pi/360. The answer is 3.7699 or 3.8 rad.

Ava deposited $14 in a savings account that earns 2.7% simple interest. What would the graph look like?
katen-ka-za [31]

Deposited amount = $14.

Rate of interest =  2.7%

In decimals 2.7 could be written by dividing 2.7 by 100, we get

0.027.

Interest earned each year = 2.7% of $14 = 0.027*14 = $0.378.

We can make a table to balance by after each year.

First year balance: First year interest + Deposited amount = 0.378 +14 = $14.378.

Second year balance: Second year interest + Deposited amount = 2*0.378 +14 = 0.756+ 14 = $14.756.

Third year balance: Third year interest + Deposited amount = 3*0.378 +14 = 1.134+ 14 = $15.134.

We get four coordinates to graph A(0,14), B(1, 14.378) , C(2, 14.756) and D(3, 15.134).

Plotting those coordinates of the points A, B, C and D on the graph.

Find the most general antiderivative of the function. (Check your answer by differentiation. Use C for the constant of the antid
Kisachek [45]

Answer:

35x - \frac{9x^2}{2} + C

Step-by-step explanation:

The antiderivative of the function is the same as the integral. To find the integral or antiderivative, reverse the process of differentiation method. Currently the function has degree 1. Through integration we increase the degree of each term by 1 and divide by the degree.

Thus 35 - 9x becomes 35x - \frac{9x^2}{2} + C. We add a constant C for any possible constant that was eliminated during differentiation.
