Answer: D
Step-by-step explanation:
If the equation is f(x) = 9x^2 -12, you can solve for the inverse by switching the x and y like this.
x = 9y^2-12.
Then you solve for y.
x = 9y^2-12.
x+12=9y^2
y^2=(x+12)/9
y=sqrt((x+12)/9)
y=sqrt((x+12))/3 which is D
If 8x300=2,400, then 8x320 would equal 2,560. Why? Because 8x20=160. 2,400+160=2,560.
Hope this helps! :)
Using the z-distribution, as we are working with a proportion, it is found that the margin of error for the 90% confidence interval is of 0.0524 = 5.24%.
<h3>What is a confidence interval of proportions?</h3>
A confidence interval of proportions is given by:

In which:
is the sample proportion.
The margin of error is given by:

In this problem, the critical value is given as z = 1.645, and since 26 out of 80 students said they would be willing to pay extra:

Then, the <em>margin of error</em> is of:

The area base when the trapezoid-based right prism has a volume of, 6cm,5 cm, and 1 cm should be 6.
Calculation of the area
Here we assume
a = 6
b = 5
c = 1
Now we know that
<h3>What is the area of the trapezoid-based right prism?</h3>


= 6
Hence, The area base when the trapezoid-based right prism has a volume of, 6cm,5 cm, and 1 cm should be 6.
