Answer:

8 percent

Step-by-step explanation:

You have to put the biggest number first, then subtract 65.00 and 60.00. You would get 5, then divide 5 and the original number (60.00). You would get 0.0833333333. Move the decimal two spots to the right. You would get 8 percent. Hope this helps!

If f(x) = kx^3+ x^2 − kx + 2, find a number k such that the graph of f contains the point (k, -10)

Elina [12.6K]

If we write $k$ where we see $x$ in the equation and set the result equal to $-10$ , we get the result.

$f(k)=k(k)^3+k^2-k(k)+2$
$=k^4+k^2-k^2+2$
$=k^4+2=-10$
$k^4=-12$
$k_{1}=\sqrt[4]{3}(-1-i)$
$k_{2}=\sqrt[4]{3}(-1+i)$
$k_{3}=\sqrt[4]{3}(1-i)$
$k_{4}=\sqrt[4]{3}(1+i)$

Find the equivalent expression to 5^6 5^11/5^5 5^6/5^1 5^1/5^16 5^11/5^-5

pashok25 [27]

Answer:

$5^{11}/5^5$

Step-by-step explanation:

$5^{11}/5^5=5^6$

$5^6/5^1=5^5$

$5^1/5^{16}=5^{-15}$

$5^{11}/5^{-5}=5^{16}$

You put $939 into an investment at 6% for 6 years. What will be the balance at the end of 6 years

Alecsey [184]

We will use a Future Value Formula:

FV=PV(1 + i)ⁿ

$939 is our Present Value (PV)

.06 (6%) will be substitued for i (interest)

6 years will be substituated for "n" (numbers of periods)

FV = $939 (1 + .06) ^6

FV = 1331.989446 or rounded to <u>1331.99 balance at the end of 6 years</u>
