Answer:
Explanatory Variable
Step-by-step explanation:
The variable that we can change is called the Explanatory variable.
The response variable dependent upon the explanatory variable, as we change the value of the explanatory variable the value of the response variable is also gets changed.
The number of years smoking a cigarette is in our control so it is an explanatory variable.
and, the impact of the number of years smoking a cigarette is directly on lung capacity, so it is Response variable.
Answer:
D
Step-by-step explanation:
So we have the equation:
And we want to solve for x.
We can solve it by completing the square.
First, subtract 58 from both sides:
Divide the b term by 2 and square it:
So, add 9 to both sides:
On the left, the perfect square trinomial pattern. Add on the right. So:
Take the square root of both sides:
The square root of -49 is 7i:
Add 3 to both sides:
So, our answer is D.
And we're done!
Answer:
The degree of a polynomial is the largest exponent on one of its variables (for a single variable), or the largest sum of exponents on variables in a single term (for multiple variables).
Step-by-step explanation:
ere, the term with the largest exponent is , so the degree of the whole polynomial is 6.
