Given f(x) =x-7 and g(x) =x2 find g(f(4))

8090 [49]

Answer: g(f(4))=9

Step-by-step explanation:

To find g(f(4)), you first find f(4). Then, you plug it into g(x).

f(4)=4-7 [subtract]

f(4)=-3

Now, we know f(4) into g(x).

g(f(4))=(-3)² [exponent]

g(f(4))=9

Now, we know that g(f(4))=9.

Factor the polynomial: – x3 - 4x2 - 5x

Alinara [238K]

Answer:

$-x3-4x2-5x=-x(x^2+4x+5)$

Step-by-step explanation:

we are given the polynomial as

$-x3-4x2-5x$

here we can see that the GCF of $-x^3$ , $-4x^2$ and $-5x$ is

$-x$

Hence we take it outside the bracket

$-x(x^2+4x+5)$

The polynomial within the bracket $x^2+4x+5$ can not be factorized further , hence this would be our final answer.

It takes Max 5.5 minutes to do 60 pull ups which includes a break in between. It takes him 8 minutes to do 120 pull ups which in

Ivahew [28]

Answer: 648 pull-ups

Step-by-step explanation:

Given

Max take 5.5 minutes to do 60 Pull-ups with a break in between

Similarly, it took 8 minutes for 120 pull-ups

Suppose the time taken for a single pull-up and break is x and y minutes

So, it can be written

$\Rightarrow 60x+y=5.5\quad \ldots(i)\\\Rightarrow 120x+y=8\quad \ldots(ii)\\\\\text{Solve (i) and (ii) we get}\\\\x=\dfrac{2.5}{60}\ min \ or\ \ 2.5\ s\\\\y=3\ min$

Now, suppose max perform at this rate, and the total pull-ups are P in 30 minutes

$\therefore P\times \dfrac{2.5}{60}+3=30\\\\\Rightarrow P\times \dfrac{2.5}{60}=27\\\\\Rightarrow P=648\ \text{Pull-ups}$
