Answer:
she invested 6600 at 3% and 3400 at 2.5%
Step-by-step explanation:
Simple interest = amount deposited x time x interest rate
Let the amount deposited in in the account bearing 3% interest by represented with a
Let the amount deposited in in the account bearing 2.5% interest by represented with (10,000 - a)
a x 0.03 + (10,000 - a) x 0.025 = 283
0.03a + 250 - 0,025a = 283
collect like terms
0.03a - 0.025a = 283 - 250
0.005a = 33
a = 6600
the amount deposited in the 2.5% account = 1000 - 6600 = 3400
|-3| This means the absolute value of -3 which is +3. Anytime you see ANY number in these vertical bars, that means you need to change the number within to a positive value. If this |3| was positive, it would still be +3.
Hope this helps!
Answer:
a
Step-by-step explanation:
The inverse function of f(x) is
and the domain is x > 6
<h3>How to determine the inverse function?</h3>
The function is given as:
f(x) = x^2 + 6
Rewrite as:
y = x^2 + 6
Swap x and y
x = y^2 + 6
Subtract 6 from both sides
y^2 = x - 6
Take the square root
![y = \sqrt{x - 6}](https://tex.z-dn.net/?f=y%20%3D%20%5Csqrt%7Bx%20-%206%7D)
Rewrite as:
![f^{-1}(x) = \sqrt{x - 6}](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%20%3D%20%5Csqrt%7Bx%20-%206%7D)
Hence, the inverse function of f(x) is
and the domain is x > 6
