Ok so, here goes:
simple interest: r- rate, A- amount in the end, t- time, P- principal
<span>r = (1/t)(A/P - 1)
</span>Putting in our numbers
r = (1/4)((21236/5309) - 1) = 0.75
r = 0.75
Converting r decimal to R a percentage
R = 0.75 * 100 = 75%/year
The interest rate required to get a total amount, principal plus interest, of $21,236.00 from simple interest on a principal of $5,309.00 over 4 years is 75% per year.
Answer:
The only function that has only one zero at -6 is f(x) = (x + 6)(x + 6)
Step-by-step explanation:
We have a function:
f(x)=(x+6)(x+6)
This function is also equal to f(x)=(x+6)^2
This is the square of the binomial. It has only one zero
f(x)=(x+6)^2 = 0
If we take square root we get:
√(x+6)^2 = 0
x+6 =0
x= -6
The only function that has only one zero at -6 is f(x) = (x + 6)(x + 6)....

Answer:
2/5 =0.4
Step-by-step explanation:
Decimals are one of the method of representation of fractions in which there is power of 10 in the denominator of the fraction. They are 10,100,1000,10,000 ,100,0000 and so
Example = 1/10 = 0.1
1/100 = 0.01
1/1000 = 0.001
In 2/5 we have to make the denominator 10
since in denominator there is five , can be made 10 by multiplying it by 2
2/2 = 1 and 1* x = x , hence if we multiply numerator and denominator by 2 it won't change the fraction.
2/5×2/2=2×2/5×2=4/10=0.4
Thus, 2/5 =0.4 in decimal form.
Yep, no question, message me if u have a question :)
