Express 630 grams as a percentage of 1 kilogram

Mathematics

63%

To express as a percentage divide 630 g by 1 Kg and multiply by 100%

note that 1 Kg = 1000 g ( units must be the same)

\frac{630}{1000} × 100% = 63%

Let f (x)=1/x and g (x)=x^2+5x. A. Find (f×g)(x). B. Find the domain and range of (f×g)(x).
Ira Lisetskai [31]

we are given

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

g(x)=x^2+5x

(A)

(f×g)(x)=f(x)*g(x)

now, we can plug it

(fXg)(x)=\frac{1}{x} (x^2+5x)

we can simplify it

(fXg)(x)=\frac{1}{x} (x(x+5))

(fXg)(x)=x+5

(B)

Domain:

Firstly, we will find domain  of f(x) , g(x) and (fxg)(x)

and then we can find common domain

Domain of f(x):

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

we know that f(x) is undefined at x=0

so, domain will be

(-\infty,0)∪(0,\infty)

Domain of g(x):

g(x)=x^2+5x

Since, it is polynomial

so, it is defined for all real values of x

now, we can find common domain

so, domain will be

(-\infty,0)∪(0,\infty)..............Answer

Range:

Firstly, we will find range of f(x) , g(x) and (fxg)(x)

and then we can find common range

Range of f(x):

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

we know that range is all possible values of y for which x is defined

since, horizontal asymptote will be at y=0

so, range is

(-\infty,0)∪(0,\infty)

Range of g(x):

g(x)=x^2+5x

Since, it is quadratic equation

so, its range will be

[-6.25,\infty)

now, we can find common range

so, range will be

(-6.25,0)∪(0,\infty).............Answer

How do you solve this please help
Andrews [41]
I’m pretty sure it’s 18
That square don’t in the corner is 90.
To find x you have to divide 2x
2x/2 = 90/2
X = 18
