The Area of a square at right is 72 square units Find the value of X, <br>Did I do this right?
Assoli18 [71]
Yes, your work is correct.

The diagram does illustrate x²+6x+9=72.  This is also represented by

(x+3)² = 72

We can take the square root of both sides:
\sqrt{(x+3)^2}=\sqrt{72}&#10;\\&#10;\\x+3=\pm 6 \sqrt2&#10;\\&#10;\\x+3-3=\pm 6 \sqrt{2} -3&#10;\\&#10;\\x=-3\pm 6\sqrt{2}

When we evaluate this, the answers are x = -11.5 or x = 5.5.

The table shows the value of an account x years after the account was opened. Based on the exponential regression model, which i
lana66690 [7]

Answer:

Correct choice is B

Step-by-step explanation:

The exponential regression model can be written as exponential function

y=a\cdot b^x.

Then

5,000=a\cdot b^0=a,\\ \\5,510=a\cdot b^2\Rightarrow 5,510=5,000\cdot b^2,\\ \\b^2=\dfrac{5,510}{5,000}=\dfrac{551}{500}\Rightarrow b\approx 1.05.

Thus,

y=5,000\cdot (1.05)^x.

When x=12, you get

y(12)=5,000\cdot (1.05)^{12}\approx \$8,980.
