Answer:
5.19%
Step-by-step explanation:
The amount of an account (A) earning simple interest rate r for time t on principal P is ...
A = P(1 +rt)
Filling in the given values and solving for r gives ...
6000 = 5500(1 +r(21/12))
12/11 = 1 + r(7/4) . . . . . . . . . . divide by 5500, simplify fractions
1/11 = r(7/4) . . . . . . . . subtract 1
4/77 = r . . . . . . . . . . . multiply by 4/7
r ≈ 0.051948 ≈ 5.19%
You will be earning about 5.19% annual simple interest.

Answer:
3.16 or -3.16
Step-by-step explanation:
Add 10 and take the square root.
x^2 = 10
x = ±√10 ≈ ±3.16
x is 3.16 or -3.16
Answer:
Step-by-step explanation:
Recall the trigonometric identity .
Therefore, given , rewrite the left side of the equation:
Subtract from both sides:
Factor out from both terms on the left:
We now have two cases:
Since the problem stipulates that is in the interval , we have:
Recall that square brackets mean inclusive and parentheses mean exclusive. Therefore, .
Answer:
y = 36/5
Step-by-step explanation:
The formula for direct variation is
y = kx where k is a constant
We know y =12 and x= 5
12 = k*5
12/5 = k
The formula is
y = 12/5 x
Now find y = when x=3
y = 12/5 *3
y = 36/5
Answer:
4
Step-by-step explanation:
First let’s write out the info:
<u>X Y</u>
5 10
2 ?
Five is to ten as two is to what? Well let’s find out.
Five times TWO is ten, so logically, we multiply two times two.
<em>2x2=4</em>
The answer is 4
I hope this helps! :D
pls give thx and brainliest if I’m right ;)
