Answer:

The answer has to be A

Step-by-step explanation:

The trees have nothing changed about them, so they can be considered to be the control. In additon, placebo is given as a control in medical trials, so it cannot be correct. And, the students have nothing changed in D, so the answer to this question has to be A, where the patients are given a new drug.

Answer:

D 20 *1.10 * 1.05

Step-by-step explanation:

We have 19.8 tons of wheat.  That is close to 20 tons

We increase by  9.8 percent. 9.8% is close to 10%

When we increase, that is 100% of what we had plus the increase, so we multiply by 100 +10% or 110%.  In decimal form that is 1.1

20 *1.10

Then the next year we increase by 5.1%.  That is close to 5%

We have 100% plus the 5% or 105%, which in decimal form is 1.05

We multiply what we had (20 *1.10) by 1.05

20 *1.10 * 1.05

This is the total amount we have

At which values of X does the function F(x) have a vertical asymptote check all apply F(x) =3/(x+2) (x-7)
finlep [7]

Answer:

When x = -2 or when x = 7

Step-by-step explanation:

x+2 is a factor in the denominator. If x = -2, the factor becomes zero.

x-7 is a factor in the denominator. If x = 7, the factor becomes zero.

We can't have zero as a factor in a denominator because division by zero is not defined. It doesn't have any meaning.
