after 6 months, $1.78 simple interest was earned on an investment of $890. what was the annual interest rate
umka21 [38]
First you have to double the simple interest to get the amount earned in 1 year. That gives $3.56 earned and a total balance of $893.56
r = (1/t)(A/P - 1)  t=time, A=amount of money with interest, P=amount invested
r = (1/1)((893.56/890) - 1) = 0.004
r = 0.004
 now convert to a decimal to get .04 = 4%

(2c^{-5})^{3} simplify ​
andrew-mc [135]

Answer:

Step-by-step explanation:

If this is

(2c^{-5})^3 then you distribute the 3 to both terms inside the parenthesis (the 2 and the c^-5).  2 cubed is 8.  The rule for the power to power is that you multiply the powers together to get -15.  So the final simplification is

8^{-15}

Please help. I’ll mark you as brainliest if correct!
chubhunter [2.5K]

Answer:

\boxed{\sf \ \ \ f^{-1}(x)=1+\sqrt{x} \ \ \ }

Step-by-step explanation:

the minimum of f is for x = 1 and f(1)=0

f is decreasing for x<=1 and increasing for x>=1

so the domain is [1;+\infty[

f^{-1}(f(x))=x =f^{-1}((x-1)^2)\\\\f(f^{-1}(x))=x=(f^{-1}(x)-1)^2

x>=1 so x is positive and we can take the square root

so f^{-1}(x)=1+\sqrt{x}
