Shaun's savings can be modeled by the regression equation y = 6x^2 + 75x+200. Which of the following is the best prediction for
1 answer:
Answer:
D
Step-by-step explanation:
The equation given gives y in terms of x, where y is Shaun's savings and x is the number of months.
<em>We want to know the amount he will save in 25 months, so we can plug in x = 25 into the equation and get a value of y, that is the amount he will save. So:</em>
D is the correct answer.

Answer:
Step-by-step explanation:
So we have the equation:
And we want to solve for x. In other words, we want to isolate the x-variable.
So, add 2y to both sides of the equation.
On the left, the 2y cancel. Simplify the right:
And we're done!
We know in these kind of triangles that have a 90 degrees angle, we can do:
so the first question:
and then:
so , when you want to rationalize , usually you must multiply the irrational factor as 1:
so , now multiply:
in the next question,we know negative numbers in radical don't have any solution so 2 is correct,
