Answer:
I believe it is C) They both involve writing a rate.
hope this helps
Step-by-step explanation:
<span>For this case we have the following equation:</span>
<span> (x + 2) 2 + y2 = 10</span>
<span> We must remember that the standard equation of the circle is given by:</span>
<span> (x - h) 2 + (y - k) 2 = r2</span>
<span> Where r is the radius.</span>
<span> Therefore, in the given equation the radius is:</span>
<span> r ^ 2 = 10</span>
<span> Clearing we have:</span>
<span> R = root (10)</span>
<span> Answer:</span>
<span> The length of the radius of the circle is:</span>
<span><span> √ (10)</span></span>
Answer:
$1545.65.
Step-by-step explanation:
We have been given that Victor has a credit card with an APR of 13.66%, compounded monthly. He currently owes a balance of $1,349.34.
To solve our given problem we will use compound interest formula.
, where,
A = Final amount after t years,
P = Principal amount,
r = Interest rate in decimal form,
n = Number of times interest is compounded per year,
t = Time in years.
Let us convert our given interest rate in decimal form. 
Upon substituting our given values in compound interest formula we will get,
≈ $
Therefore, Victor will owe an amount of $1545.65 after one year.
Answer:
Some k's that will work:
1/2
1/3
1/4
(There are infinitely many answers.)
Step-by-step explanation:
Obviously 5 won't work because 25<5 is not true.
What about a negative? -5?
25<-5 is not true.
How about 1/3? 1/9<1/3 is true so 1/3 works.
Note: Think of a number between 0 and 1.
1/4<1/2 is true and (1/2)^2=1/4.
1/16<1/4 is true and (1/4)^2=1/16.
You can solve k^2<k.
Subtract k on both sides.
k^2-k<0
Factor.
k(k-1)<0.
So k^2-k is a parabola with x-intercepts (k-intercepts) at k=0 and k=1.
The parabola is open up so any number between 0 and 1 will satisfy k^2<k since between 0 and 1 the parabola is less than y=0 ( the x-axis).
