If 2000 is placed into a bank account that pays 3% compound interest per year how much will be in the account after 2 years
Answer:
Account Balance = Principal x (1 + interest rate (decimal)) number of years, compounded annually.
Step-by-step explanation:
This is based on the information provided: 2121.80 (1.03)2 = 2000 So, on your initial deposit of 2000, you can collect 121.80 in interest after two years.

Parallelogram PQRS has diagonals that are perpendicular. Based on that, which statement is most correct?
A- Parallelogram PQRS is also a rectangle
B- Parallelogram PQRS is also a rhombus.
C- Parallelogram PQRS is neither a rectangle nor a rhombus.
D- Parallelogram PQRS is both a rectangle and a rhombus, so it is a square.
Answer:
B- Parallelogram PQRS is also a rhombus.
Step-by-step explanation:
Given
Parallelogram PQRS with perpendicular diagonals
Required
Which of the option is true
(a) PQRS can be a rectangle
A rectangle do not have perpendicular diagonals.
Hence, (a) is false
If (a) is false, then (d) is also false
(b) PQRS can a rhombus
The diagonals of a rhombus are not perpendicular.
So (b) is true
No need to check for (c), since only option is true
Answer:
B- Parallelogram PQRS is also a rhombus.

Jesse collects data on his math scores on the last 12 tests and the number of hours he spent completing his math homework assignments and studying in the week before every test. He creates a scatter plot to show the data. The regression line shown on the graph best models the data on the scatter plot.
Based on the given model, how many hours in the week before the test does Jesse need to study to get a score of 90 on the test? Round your answer to the nearest hour.
Answer:
24 hoursStep-by-step explanation:
Using the two points on the regression line, let's find its equation.
Points:
(0, 30) and (8, 50)The slope:
(50 - 30)/8 = 2.5The y-intercept is
30The equation:
y = 2.5x + 30Solve for x if y = 90
90 = 2.5x + 302.5x = 60x = 60/2.5x = 24The answer is 24 hours

Find the area of a regular hexagon with an apothem length of 12.1 and a side length of 14
Answer:
area = 520 units²
Step-by-step explanation:
divide the hexagon into 6 equal triangles.
each triangle has a base of 14 and a height of 12.1 so:
the area of one triangles = 1/2BH = 1/2(14)(12.1) = 86.8 units ²
86.8 x 6 triangles = 520.8 units²

Could someone help me find an equation ❤️
Answer:
-(2/3)x+4
Step-by-step explanation:
For the slope you do rise over run, since the graph intercepts the y-axis at 4 and goes down to 0 the rise is -4 and from the same point the graph "runs" 6 the rise/run is -4/6 which can be simplified to -2/3. For the y-intercept you simply find where the graph touches the y-intercept and add (or subtract if the number is negative) that to the end of the equation.
Write the standard equation of the circle if the center is (-1,2), and a point on the circle is (2,6).
Plzzzzz helpppp me
Answer:
(x + 1)² + (y - 2)² = 25Step-by-step explanation:
The center is given:
(-1, 2)Find the radius, the distance from the center to a point (2, 6)
r² = (2 - (-1))² + (6 - 2)² = 3² + 4² = 25r = √25 = 5Use circle formula:
(x - h)² + (y - k)² = r²(x - (-1))² + (y - 2)² = 5²(x + 1)² + (y - 2)² = 25A rectangle has an area of 235.2m squared. One of the sides is 2.8m in length. work out the perimeter of the rectangle, please?
Answer:
P = 173.6 mSteps:
given:
A = 235.2 m²
S1 = 2.8 m
S2 = A/S1
S2 = 235.2/2.8
S2 = 84 m
P = 2(S1+S2)
P = 2(2.8+84)
P = 2 × 86.8
P = 173.6 m

A washer and a dryer cost $726 combined. The washer costs $76 more than the dryer. What is the cost of the dryer?
Answer:Cost of dryer=$325
Step-by-step explanation:
Let the dryer be represented as x
and the washer be x+76
such that the price of both can be written as
dryer + washer=$726
x + x+76=726
2x+76=726
2x=726-76
2x=650
x=650/2=325
Cost of dryer =x=$325

$1,036 3
$1,084 7
$1,120 10
B.

$1,004.80 4
$1,009.60 8
$1,013.20 11
D.
Balance Due Number of Months
$1,005 5
$1,007 7
$1,012 12
Answer:
The answer is B
Step-by-step explanation:
Given: Cory owes $1,000 to his bank. During the time of his loan, he is charged a real of 12% simple annual interest
To find: If he does not make any payments on his loan, draw table showing the relationship between the amount he owes and the number of months
Solution:
Loan amount P = $ 1000
Rate of interest R = 12 % per annum
SI = P * R * T /100
one month T = (1/12) Years
Interest per month = 1000 * 12 * (1/12) /100 = $ 10
Hence interest chaarges $ 10 per month
Cory owes to bank the loan amount and interest
Cory owes = 1000 + 10 n
where n is the number of months
Month Amount
0 1000
1 1010
2 1020
3 1030
4 1040
5 1050
6 1060
7 1070
8 1080
9 1090

A circle has a diameter of 18. The sector has a central angle of 30 degrees. What is the area of the sector?
Answer:
21.21
Step-by-step explanation:
Area of a circle is A = π r^2
Variables:
r = 18/2 = 9
θ = 30 deg
Find the area:
A = π r^2
A = π 9^2
A = 254.47
Find the area of the sector:
θ/360 * A
= 30/360 * 254.47
= 21.21
The average human reaction time from eye to finger is 0.16 second. How is this expressed as a fraction?
Answer:
4/25 seconds
Step-by-step explanation:
the second (0.16) is in two decimal places, so divide 16 by 100
[tex]\frac{16}{100}[/tex]
to express in the simplest form, divide the numerator and the denominator by 4
= [tex]\frac{4}{25}[/tex]

Find the intercept and slope in the graph, and find the aquation for the function.
Answer:
Slope = 3
y intercept = -8
y = 3x - 8
Step-by-step explanation:
From the table shown, we can make use of the coordinate points
(0, -8) and (1, -5)
Slope m = y2-y1/x2-x1
m = -5-(-8)/1-0
m = -5+8/1-0
m = 3/1
m = 3
Slope = 3
The standard form of an equation is y = mx+b
b is the y intercept
Substitute m = 3 and (0, -8) into y = mx+b
-8 = 3(0) + b
-8 = b
b = -8
Hence y intercept is -8
Get the required equation
Recall that y = mx+b
y = 3x + (-8)
y = 3x - 8
This gives the required equation
