Answer:

the classmark of the class is 162.5

Step-by-step explanation:

The computation of the class mark is shown below:

Given that

160 - 165

So, the class mark of the class is

= (Upper limit + lower limit) ÷ 2

= (160 + 165) ÷ 2

= 162.5

Hence, the classmark of the class is 162.5

Which model represents the factors of 4x2 - 9?

lesya [120]

Answer:

The factors are $(2x-3)(2x+3)$

Step-by-step explanation:

Subtraction of perfect squares:

The factorization of the subtraction of perfect squares is given by:

$a^2 - b^2 = (a-b)(a+b)$

In this question:

$4x^2 - 9 = (2x)^2 - 3^2$

$(2x)^2 - 3^2 = (2x-3)(2x+3)$

The factors are $(2x-3)(2x+3)$

The function h(x)=1/x^2+1 is the result of the composition f(g(x)). If g(x) = x^2+1,what is f(x)? A f(x)=1/square root x B f(x)=

HACTEHA [7]

Answer:

Option B is correct

Step-by-step explanation:

Given: $h(x)=\frac{1}{x^2+1}$ is the result of the composition $f(g(x))$ .

Also, $g(x)=x^2+1$

To find: $f(x)$

Solution:

Take $f(x)=\frac{1}{x}$

Now check whether $h(x)$ is equal to $f(g(x))$ or not.

First find $f(g(x))$

$f(g(x))=f(x^2+1)=\frac{1}{x^2+1}$

Also, $h(x)=\frac{1}{x^2+1}$

Therefore,

$h(x)=f(g(x))$

So,

Option B is correct
