Robert Duncan made a $1500 deposit to savings account paying 1.6 annual interest compounded semi annually if he kept the money o
Ahat [919]

Answer: $12

Step-by-step explanation:

The formula to calculate the compound interest , if the interest is compounded semi-annually :-

A=P[(1+\dfrac{r}{2})^{2t}-1]

, where P = Principal amount

r = rate of interest ( in decimal)

t= Time ( in years)

Given : P= $1500

r= 1.6 % =0.016

t= 6  months = \dfrac{1}{2} year  [∵ 1 year = 12 months]

Then, the interest earned by Robert in 6 months will be :-

A=1500[(1+\dfrac{0.016}{2})^{2\cdot\frac{1}{2}}-1]

A=1500[(1+0.008)^{1}-1]

A=1500[1.008-1]

A=1500[0.008]=12

Hence, Robert earned $12 as interest .

The graph shows the system y=2x+1 y=2x^2+1 Which ordered pairs are solutions of the system?
zhenek [66]
Hey!


To solve this problem, we would really have to graph both equations.

<em>OPEN THE FIRST IMAGE</em>

The first image I provided was the image of this equation graphed: <span>y=2x+1

<em>OPEN THE SECOND IMAGE</em>

The second image I provided was the image of this equation graphed: </span><span>y=2x^2+1


<em>PLEASE DO NOT LOOK AT THE THIRD IMAGE YET!</em>


The first image has two points. One at ( -0.5, 0 ) and the other at ( 0, 1 ).

The second image has only one point, which is at ( 0, 1 ).

<em>OPEN THE THIRD IMAGE</em>

Now, when both are combined we see that they intersect at two points, which are ( 0, 1 ) and ( 1, 3 ).

So, our answer is...

<em>The ordered pairs that are the solution to the system are</em>  </span><span>( 0,1 ) and ( 1,3 ).

Hope this helped!
