[Calc 1] An explanation on how to best solve this. I've been stuck trying to use chain rule

Answer:

  G'(y) = 4y^7(y+4)/(y+2)^5

Step-by-step explanation:

Work it a piece at a time.

Define z = y^2/(y+2). Then your derivative is found from the power rule as ...

  G = z^4

  G' = 4z^3·z'

Now, define z = u/v. Then your derivative is found using the quotient rule:

  z' = (vu' -uv')/v^2 = ((y+2)(2y) -(y^2)(1))/(y+2)^2

Putting this together we have ...

  G'(y)=4\left(\dfrac{y^2}{y+2}\right)^3\cdot\dfrac{y^2+4y}{(y+2)^2}\\\\\boxed{G'(y)=\dfrac{4y^8+16y^7}{(y+2)^5}}

What the questions are asking help ASAP please
Rudiy27

Answer:

Step-by-step explanation:

A scalar is a constant value that is multiplied throughout a matrix.

e.g.

In number 1 the set up would look like this

3 * \left[\begin{array}{ccc}3&-1&5\\2&1&-4\\-6&3&2\end{array}\right]

To solve this, you must distribute the 3 to each value within the matrix

The solution to #1 would be

M = \left[\begin{array}{ccc}9&-3&15\\6&3&-12\\-18&9&6\end{array}\right]

SAT scores are distributed with a mean of 1,500 and a standard deviation of 300. You are interested in estimating the average SA
kotegsom [21]

Answer:

I should use at least 304 students

Step-by-step explanation:

Margin error (E) = t × sd/√n

E = 40

sd = 300

confidence level (C) = 98% = 0.98

significance level = 1 - C = 1 - 0.98 = 0.02 = 2%

t-value corresponding to 2% significance level and infinity degree of freedom is 2.326

n = (t×sd/E)^2 = (2.326×300/40)^2 = 17.445^2 = 304 (to the nearest integer)

Which is the equation of the line with a slope of 9 that goes through the point (1, 10.6)?
natta225 [31]

Answer:

y=9x+1.6

Step-by-step explanation:

  • y-10.6=9(x-1)
  • y-10.6=9x-9

bring the 10.6 over by adding it to both sides

  • y= 9x + 1.6
