Assume that a 30-month CD purchased for $2500pays simple interest at an annual rate of 5.5%. How much total interest does it ear
otez555 [7]

Answer:

Interest earned: 343.75

Balance at maturity: 2843.75

Step-by-step explanation:

simple interest formula

P(1+it)

interest earned:

(interest earned is the ending balance minus the beginning balance)

2500(1+.055*(30/12))-2500= 343.75

Balance at maturity

2500(1+.055*(30/12))= 2843.75

(another way to solve this part is to just add 343.75 (the interest earned) to the beginning balance)

Find the vertices and foci of the hyperbola with equation quantity x plus 5 squared divided by 36 minus the quantity of y plus 1
Sphinxa [80]

Answer:

Vertices: (1,-1), (-11, -1); Foci: (-15, -1), (5, -1)

Step-by-step explanation:

Center at (-5,-1) because of the plus 5 added to the x and the plus 1 added to the y.

a(squared)=36 which means a=6 and a=distance from center to vertices so add and subtract 6 from the x coordinate since this is a horizontal hyperbola, which is (1,-1), (-11,-1). From there you dont need to find the focus since there is only one option for this;

Vertices: (1,-1), (-11, -1); Foci: (-15, -1), (5, -1)

Find the coordinates of the intersection of the diagonals of parallelogram WXYZ with the following vertices: W (-1, 7), X (8, 7)
Nataliya [291]
The intersection of the diagonals of a parallelogram is always the midpoint of each of the diagonals, which means all we have to do is grab two opposite vertices and average their coordinates. 

<span>Let's use W and Y. </span>

<span>(-1 + 6)/2 = 2.5 </span>
<span>(7 + -2)/2 = 2.5 </span>

<span>So our point is (2.5,2.5) </span>

<span>We could also use X and Z. </span>
<span>(8 + -3)/2 = 2.5 </span>
<span>(7 + -2)/2 = 2.5 </span>

<span>Again, we get (2.5,2.5)</span>
