A person places $127 in an investment account earning an annual rate of 4.2%, compounded continuously. Using the formula V = P e r t V=Pe rt , where V is the value of the account in t years, P is the principal initially invested, e is the base of a natural logarithm, and r is the rate of interest, determine the amount of money, to the nearest cent, in the account after 16 years.
Answers
Answer: $248.68
Step-by-step explanation:
Given
Money compounded according to
[tex]\Rightarrow V=Pe^{rt}\\[/tex]
Here, P=$127
r=4.2%
t=16 years
[tex]\Rightarrow V=127e^{0.042\times 16}\\\\\Rightarrow V=127e^{0.672}=127\times 1.958\\\\\Rightarrow V=\$248.68[/tex]
Value after 16 years is $248.68
Answer: 248.69
Step-by-step explanation:
r= 4.2%
=0.042

Which graph best represents the equation y = -2x + 5?
Answers
Answer:
B) The top right choice.
Step-by-step explanation:
The graph of the equation y = - 2x + 5 is shown in figure.
Option 2 is true.
What is Equation of line?The equation of line in point-slope form passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The equation is,
⇒ y = - 2x + 5
Now,
Since, The equation is,
⇒ y = - 2x + 5
By comparing of the slope - intercept form of the equation of line,
y = mx + b we get;
⇒ Slope = - 2
And, The y - intercept = 5
So, The graph of the equation is passes through the point (0, 5) with slope - 2.

You and a friend are racing each other to swim 500 meters. You complete 50 meters in 45 seconds. Your friend completes 150 meters in 2 minutes. Who won the race and by how much?? no links
Answers
Answer:
your friend by 50 seconds
Step-by-step explanation:
150 divided by 3 equals to 50 so you would also divide 120 minutes by 3 to get 40
You: 50 meters per 45 seconds
Friend: 50 meters in 40 seconds
50 times 10 equals 500 meters so we will multiply both number of seconds by 10
You:45*10=450
Friend: 40*10=400
450>400 so the friend swims the fastest
450-400= is 50 seconds
So the friend swims the fastest by 50 seconds

Which table of values represents a line with a slope of 4/3
Answers
Answer:
c
Step-by-step explanation:
have a good day :D
to find the slope you take two points and add the y values and divide it by the x values
so you take the points (0,-2) and (3,2)
the y values are -2and2
2+2=4
the x values are 0 and 3
0+3=0
4/3=4/3 so that table does represent an equation with a slope of 4/3

Step-by-step explanation:
Given

Required
How long she waits in Wellington
From the question:
She takes the 10 30 from Christchurch
So:
[tex]Christchurch\ Depart = 10\ 30[/tex]
This implies that:
She has to wait until Wellington arrives at 11 15
So:
[tex]Wellington\ Arrives= 11\ 15[/tex]
So, the wait time is:
[tex]Wait\ time = Wellington\ Arrives - Christchurch\ depart[/tex]
[tex]Wait\ time = 11: 15 - 10: 30[/tex]
[tex]Wait\ time = 1:45\ hr[/tex]
