If you put $1,000 in a savings account that pays 5% interest compounded continuously, how much money will you have in your accou
ivann1987 [24]
Given:
Principal = 1,000
rate = 5%
term = 10 years

The continuous compound formula is: A = Pe^rt

e is a function in the calculator. However, if you are doing manual computation the value of e is 2.7183 (Napier's number)

A = 1,000 (2.7183)^0.05*10
A = 1,000 (2.7183)^0.5
A = 1,000 (1.6487)
A = 1,648.70

The money you will have in your account in 10 years will amount to 1,648.70.

Emily has some $5 bills and $10 bills she has 15 bills she has $120 how many $5 bills does she have​
Alexxx [7]

Step-by-step explanation:

Let F = The number of $5 bills and T = the number of $10 bills.  She has 15 bills total, so:

 

F+T = 15                

T = 15-F

 

She has $120 total:

 

$120 = ($5)*F + ($10)*T

$120 = $5*F + ($10)*(15-F)         [Substitute 15-F in place of T]

120 = 5F + 150 - 10F

-30 = -5F

 

6 = F

 

Check:

T= 15-F = 15=6 = 9

 

$120 = ($5)*6 + ($10)*9

$120 = $30 + $90

$120 = $120

REY [17]

The true statement about the graph of the function f(x) = x3 - 2x2 + 4x – 8 is (B) The function has 1 real zero that occurs 1 time.

<h3>How to determine the true statement</h3>

The function of f(x) is represented as:

f(x)=x^3-2x^2+4x-8

Differentiate the function f(x)

f'(x)=3x^2-4x+4

Calculate the minimum value using:

x = -\frac b{2a}

So, we have:

x = -\frac {-4}{2*3}

x = \frac {2}{3}

Substitute 2/3 in f'(x)

f'(2/3)=3*(2/3)^2-4(2/3)+4

f'(2/3)=\frac 83

The value of f'(2/3) is greater than 0.

This means that the function f(x) has 1 real zero, and it occurs once at point (2,0)

Hence, the true statement is (b)
