The table shows the percent of adults who used computers from 1984

Mathematics
1 answer:
MrMuchimi3 years ago
7 0

Answer:

3.1 (nearest tenth)

Step-by-step explanation:

Year (independent variable) = x

Percent of adults (dependent variable) = y

Rate of change is given as = \frac{y_2 - y_1}{x_2 - x_1}.

Let,

(1989, 20) = (x_1, y_1)

(2007, 76) = (x_2, y_2)

Plug in the values into the equation

Rate of change = \frac{76 - 20}{2007 - 1989}

Rate of change = \frac{56}{18} = 3.1 (nearest tenth)

Write the slope-intercept form of the given line. Include your work in your final answer. Type your answer in the box provided o
kolbaska11 [484]
Answer: y = x -1

reasoning: the slope is 1 because the rise/run = 1/1, which simplifies to 1.
                 the y intercept is -1 because the line passes through the y axis at -1.

hope this helps!

1. Michael invests $2000 in an annuity that offers an interest rate of 4% compounded quarterly for 5 years. What is the value of
Amanda [17]
1. The formula for annual compound interest, including principal sum, is:

A = P (1 + r/n)ⁿˣ

Where:

A = the future value = ?
P = the principal investment amount = $2000
r = interest rate = 4%
n = the number of times that interest is compounded per year = 4
x = the number of years = 5

Calculations:

A = 2000 (1 + 0.04/4)²⁰

A = 2000 (1 + 0.01)²⁰

A = 2000 (1.01)²⁰

A = 2000 ₓ 1.22

A = $2440.38 


2. The formula for annual compound interest, including principal sum, is:

A = P (1 + r/n)ⁿˣ

Where:

A = the future value = ?
P = the principal investment amount = $50
r = interest rate = 48%
n = the number of times that interest is compounded per year = 12
x = the number of years = 2

Calculations:

A = 50 (1 + 0.48/12)²⁴

A = 50 (1 + 0.04)²⁴

A = 50 (1.04)²⁴

A = 50 ₓ 2.56

A = $128.16


3. The formula for annual compound interest, including principal sum, is:

A = P (1 + r/n)ⁿˣ

Where:

A = the future value = ?
P = the principal investment amount = $50
r = interest rate = 4%
n = the number of times that interest is compounded per year = 12
x = the number of years = 3

Calculations:

A = 50 (1 + 0.04/12)³⁶

A = 50 (1 + 0.003)³⁶

A = 50 (1.003)³⁶

A = 50 ₓ 1.12

A = $56.36

The equation of the graphed line is 2x – y = –6.<br><br><br> What is the x-intercept of the graph?
Bas_tet [7]
U can either look at ur graph...and where the line crosses the x axis is ur x intercept...which is (-3,0)

OR

take ur equation and sub in 0 for y, and solve for x, ur x intercept.
2x - y = -6
2x - 0 = -6
2x = -6
x = -6/2
x = -3.....so ur x intercept is (-3,0)
