6. Identify the terms in the expression: <br> 9 + 11y – y2 + y3 – 4y4

Goshia [24]

Normally you will see these expressions in reverse order with descending powers of the variable.
-4y^4 + y^3 - y^2 + 11y + 9
So you start with the high order terms and end with a constant.

Given:

The table of data values.

To find:

What is the percentage of 10th grade students are in 2 clubs.

Solution:

From the given table it is clear that the number of 10th grade students are in 2 clubs is 12.

Total number of students in 10th grade is:

$125+12+15=152$

Now, the percentage of 10th grade students are in 2 clubs is:

$\text{Required percentage}=\dfrac{\text{Number of 10th grade students are in 2 clubs}}{\text{Total number of students in 10th grade}}\times 100$

$\text{Required percentage}=\dfrac{12}{152}\times 100$

$\text{Required percentage}=\dfrac{1200}{152}$

$\text{Required percentage}\approx 7.89\%$

Therefore, the percentage of 10th grade students are in 2 clubs is 7.89%.

To one-one functions g and h are defined as follows.

Andreyy89

Answer:

9
(x-8)/3
-1

Step-by-step explanation:

The inverse function for a set of ordered pairs can be found by swapping the x- and y-coordinates in each pair.

$g^{-1}(-1)=9\qquad\text{from the $g(x)$ ordered pair $(9, -1)$}$

The inverse of a function expressed algebraically can be found by swapping the x- and y-variables and solving for y.

$h^{-1}(x)\qquad\text{is found from }x=h(y)\\\\x=3y+8\\x-8=3y\\\\y=\dfrac{x-8}{3}\\\\\boxed{h^{-1}(x)=\dfrac{x-8}{3}}$

A function of its own inverse returns the original value:

$\boxed{\left(h\circ h^{-1}\right)(-1)=-1}$
