You have $1000 to invest in two different accounts. In order to save the money you need for college, you need to average 6.6 per

Aleks04 [339]

Answer:

a) $500 + $525 = $ 1,025

b) $420 + $642 = $ 1,062

c) $210 + $856 = $ 1,066

d) $840 + $214 = $ 1,056

Step-by-step explanation:

Compound Interest Equation

A = P(1 + r/n)^nt

Where:

A = Accrued Amount (principal + interest)

P = Principal Amount

I = Interest Amount

R = Annual Nominal Interest Rate in percent

r = Annual Nominal Interest Rate as a decimal

r = R/100

t = Time Involved in years, 0.5 years is calculated as 6 months, etc.

n = number of compounding periods per unit t; at the END of each period

Compound Interest Formulas and Calculations:

Calculate Accrued Amount (Principal + Interest)

A = P(1 + r/n)^nt

Calculate Principal Amount, solve for P

P = A / (1 + r/n)^nt

Calculate rate of interest in decimal, solve for r

r = n[(A/P)^1/nt - 1]

Calculate rate of interest in percent

R = r * 100

Calculate time, solve for t

t = ln(A/P) / n[ln(1 + r/n)] = [ ln(A) - ln(P) ] / n[ln(1 + r/n)]

The midpoint of line segment AB is (-2,1). If the coordinates of B are (0,2) what are the coordinates of A?

Whitepunk [10]

The required coordinate of A will be at (-4, 0)

When a point bisects a line, it cuts the line into two equal parts and the point on that line is known as its midpoint. The expression for calculating the midpoint of a line is expressed as;

$M(X, Y)= [{ \frac{x_2+x_1}{2} , \frac{y_2+y_1}{2} ]$ where:

$X =\frac{x_2+x_1}{2} \\Y=\frac{y_2+y_1}{2}$

From the question, we are given the following coordinate points

$X=-2\\x_1=0\\$

Get x₂;

$X =\frac{x_2+x_1}{2}\\-2 =\frac{x_2+0}{2}\\2 \times -2=x_2+0\\-4=x_2\\ Swap\\x_2=-4\\$

Get y₂;

$Y =\frac{y_2+y_1}{2}\\1 =\frac{y_2+2}{2}\\2 \times 1=y_2+2\\2=y_2+2\\y_2=2-2\\y_2=0$

Hence the coordinate of A will be (-4, 0)

Find the value of x: 7x + 15 = 38

borishaifa [10]

Answer:

23/7

Step-by-step explanation:

7x + 15 = 38

subtract 15 from both sides : 7x+15-15=38-15

7x=23

divide both sides by 7: 7x/7 = 23/7

x=23/7

1. For each expression, use the distributive property to write an equivalent expression.

slavikrds [6]

Answer:

a. 4x+8

c. 8x+12

d. 6x+6y+6z

b. 6x+8x

Step-by-step explanation:

The distributive property means that the term on the outside of the parentheses can be multiplied by each term on the inside. Take question C for example. You have to multiply 4 by 2x to get 8x, but also multiply 4 by 3 to get 12. These two terms are then connected by the addition as seen within the parentheses, which gives you 8x+12.
