Subtract -3/6 hr
Answer:
6.32 years
Step-by-step explanation:
To get the time taken to triple the amount invested, we must first establish the compound interest formula. When a principal amount P is invested for a time n at a rate r percent, the amount A after n years may be expressed as
A = P (1 + r)^n
Hence if $1,225 is to triple, the amount will be
= $1,225 *3
= $3,675
The time n for this to happen may be computed through the equation
$3,675 = $1,225 ( 1 + 0.19)^n
3 = 1.19^n
take the log of both sides
log 3 = log 1.19^n
using the law of logarithms that log a^b = b log a
n log 1.19 = log 3
n = log 3 / log 1.19
n = 6.32 years
Answer:
B.) 5, -1
Step-by-step explanation:
Formula:
ax^2+bx=c
Shift the equation and set it equal to 0 by subtracting c.
ax^2+bx+c=0
So, in this case:
x^2-4x=5
Shift the equation:
x^2-4x-5=0
a= 1
b= -4
c= -5
Now, to figure out the zeros of an equation like this:
You need to find two numbers that multiply to c (-5), but also add to b (-4).
These numbers are 5 and -1
So, the zeros of the equation are 5 and -1.

Answer:
Step-by-step explanation:
Given
Slope of line = -4
Point = (-3,1)
Required
Point slope equation of line
To get the equation of line, we make use of the following slope formula
Where m = -4 and 
So; becomes
Multiply both sides by x + 3
Hence, the point slope form of the line is
