If we have a negative exponent of a number, we can get rid of the minus and make the exponent positive by expressing the number as a fraction like “1/x^n”. (In other words, 1 divided by the number with the now-positive exponent).

So, this would be 1/3^2

And we know the square of 3 is 9, so our answer would be 1/9.

If a sentence is defined recursively by f(0)=3 and f(n+1) = f(n) +5 for n ? 0, then f(2) is A) 2 B) 3 C) 5 D) 8
VladimirAG [237]

The recursive formula f(n+1)=f(n)+5 means that the next term in the sequence is 5 more than the previous one.

So, we know that we start from f(0)=3, which means that the next term is

f(1) = f(0)+5 = 3+5 = 8

Similarly,

f(2) = f(1)+5 = 8+5 = 13

A study was conducted on the effects of long-term marriage (more than 10 years). Researchers gathered data from a random sample
Vanyuwa [196]

Answer:

We cannot infer a cause and effect relationship because the treatments imposed were not blocked correctly.

Step-by-step explanation:

The treatments given to the groups given in the question where not assigned proper treatments to establish proper randomized block design.

Thus, we can say the conclusion is that we can't truly infer a cause and effect relationship as the blocks were not properly done.

X^6 + y^6 = 1<br><br> What does:<br> y'' =
madreJ [45]
Before taking the derivatives of the function, simplify the equation first for smooth operation.

x^6 + y^6 = 1

Multiply the whole equation with an exponent of 1/6 for uniformity. This would get rid of the exponents of x and y. The product would be

x + y = 1^1/6
x + y = 1

Expressing in terms of x:

y = 1 - x

Now, we derive the equation:

y' = 0 -1 = -1
y" = 0
