Doris put $4000 in a 2 year cd paying 6% interest, compounding monthly. after 2 years, she withdrew all her money. what was the amount of the withdraw?

Answers

For the answer to the question above asking what was the amount of the withdraw if Doris put $4000 in a 2-year cd paying 6% interest, compounding monthly. after 2 years, she withdrew all her money?

First year Interest: I(1) = 4000[(1.005)^12 - 1] = 246.71 = penalty for early withdrawal
Value after two years: P(2) = 4000(1.005)^24 = 4508.64

Value after 2 years with penalty: V = 4000(1.005^24 - 1.005^12 + 1) = $4261.93

Answer:

Value after two years: P(2) = 4000(1.005)^24 = **** 4508.64 ***

Which equation represents a line parallel to the x-axis1) x=5
2) y=10
3) x=1/3y
4) y=5x+17

Answers

paralell lines have same slope

paralell to x axis means slope of x axis=slope of line
slopt of x axis=rise/run, rise=0, run=infinity, so slope=0

y=mx+b
m=slope
if m=0,
y=0x+b
y=b

therefor the answer is an equation that is y=constant where there is no x

answer is 2) y=10

Using the coordinates of two points (84, 80) and (74, 65), determine the slope of the line of best fit.a. The slope of the line is 1.5.
b. The slope of the line is 15.
c. The slope of the line is -10.
d. The slope of the line is -15

Answers

Answer:

a.the slope of the line is 1.5

Step-by-step explanation:

Hello

if two points of a line are known(P1 and P2), it is possible to find the slope of the line, the slope of a line is given by:

$slope=(y_(2)-y_(1))/(x_(2)-x_(1)) \nm=(y_(2)-y_(1))/(x_(2)-x_(1))\n$

$P1=(x_(1) ,y_(1)) \nP2=(x_(2) ,y_(2))$

Step 1

define

$P1=(84,80) , x_(1)=84 ,y_(1)=80\nP2=(74,65) , x_(2)=74 ,y_(2)=65$

Step 2

put the values into the equation

$m=(y_(2)-y_(1))/(x_(2)-x_(1))\nm=(65-80 )/(74-84)\nm=(-15)/(-10)\n m=(15)/(10)=(3)/(2)=1.5$

the slope=1.5

I hope it helps, have a great day

the slope of the line is 1.5

A square has a side of 6.25 feet. What is the area in square feet? Round to the correct significant digits.

Answers

The solution to this question is 39.0625.

This is because you will need to multiply the width by height. As this is in square feet it will be irrespective of which two sides we choose.

The calculation that will need to be done is the following :

6.25ft X 6.25ft which will equal 39.0625.

6.25 has three significant digits so rounding 39.0625 off to three significant digits is 39.1 square feet

Find the area of a sector with a central angle of 32° and a radius of 8.5 millimeters. Round to the nearest tenth.

Answers

You use the formula:
