Can someone help me with ratios?

Ratios can be described in different ways, if you were given a fraction such as 2/4 then we would put in 3 ways like 2/4, 2:4, and 2 to 4. So basically in any rule with fractions or anything else like that you'd have to explain it in 3 ways like my example shows.

Hopefully this helped. :)

Reduce ratio 49:21 to lowest form

mafiozo [28]

$\bf 49:21\implies \cfrac{49}{21}\implies \cfrac{7\cdot 7}{3\cdot 7}\implies \cfrac{7}{3}\cdot \cfrac{7}{7}\implies \cfrac{7}{3}\cdot 1\implies \cfrac{7}{3}\implies 7:3$

Match each operation involving f(x) and g(x) to its answer

eimsori [14]

Answer:

(g-f) (-1)= sqrt(15)

(f/g)(-1)= 0

(g+f)(2)=sqrt(3)-3

(g*f)(2)=-3*sqrt(3)

Step-by-step explanation:

We have to eval the expressions given in the point indicated.

Lets start by the first equation

(g-f)(-1)= g(-1) - f(-1)= $\sqrt{11-4*(-1)} - 1 +(-1)^{2}$ = $\sqrt{15}$

Now, lest continue with the others

(f/g)(-1)= f(-1)/g(-1)= (1-1)/sqrt(15)=0

(g+f)(2)=g(2)+f(2)=sqrt(3)-3

(g*f)(2)=g(2)*f(2)=sqrt(3)*(-3)=-3sqrt(3)
