Which one is it?? (btw the negative answer isn't right.)

Semmy [17]

Answer:

Step-by-step explanation:

Rule: a Minus power always goes to the opposite place to where it is. If it is in the denominator, it goes to the numerator. If it is the numerator, it goes to the denominator. The minus power does not affect the sign of the expression.

So you are right. The minus power does not give a minus answer.

$\dfrac{y^{-2}}{3y^4}=\dfrac{1}{3y^2y^4}=\dfrac{1}{3y^{(2 + 4)}} = \dfrac{1}{3y^6}$

Answer: A

Write the nth term of the following sequence in terms of the first term of the sequence. PLEASE HELP DUE IN 6 DAYS!!!!!!!

nalin [4]

Answer:

a + 4(n-1)

Step-by-step explanation:

The first term is a+4, the second term is a+8, the third term is a+12, etc.

A common theme that we can notice is that we add 4 for each term. For example, the second term (t₂) equals t₁+4, the third term equals t₂+4 (as a+4+4 = a+8), and so on. Another way of writing this is that we multiply 4 by (term number - 1) and add that to a. We can write this as

4 * (n-1) + a

The diameter of the cone is 6 inches. It’s height is 4 inches. What is its slant height?

Kisachek [45]

Answer:

5 inches

Step-by-step explanation:

As the height is perpendicular to the base, the radius and the height form a right angle, creating a right triangle where the slant height is the hypotenuse, thus:

$(height)^2+(radius)^2=(slant\:height)^2$

$4^2+(6/2)^2=(slant\:height)^2$

$16+9=(slant\:height)^2$

$25=(slant\: height)^2$

$5=slant\: height$

In conclusion, the slant height of the cone is 5 inches. See below for a visual.
