What is the zero of the function

olga_2 [115]

Answer:

$x=6$ (or 6)

Step-by-step explanation:

$f(x)=\frac{x^2+x-42}{x^2+3x-28}$

$0=\frac{x^2+x-42}{x^2+3x-28}$

$0=x^2+x-42$

$0=(x+7)(x-6)$

$x=-7$ or $x=6$

<u>Now check both solutions:</u>

$f(-7)=\frac{(-7)^2+(-7)-42}{(-7)^2+3(-7)-28}$

$f(-7)=\frac{49-7-42}{49-21-28}$

$f(-7)=\frac{42-42}{28-28}$

$f(-7)=\frac{0}{0}$

Therefore, $x\neq-7$ because there is a hole at $(-7,0)$ . The denominator, in addition, can never be 0, so the function is undefined for $x=-7$ .

$f(6)=\frac{(6)^2+(6)-42}{(6)^2+3(6)-28}$

$f(6)=\frac{36+6-42}{36+18-28}$

$f(6)=\frac{42-42}{54-28}$

$f(6)=\frac{0}{24}$

$f(6)=0$

Since $f(6)=0$ , then $x=6$ is the only zero of the function.

The dosage for a drug used to treat a male Siberian tiger that weighs 550 pounds is based on the tiger's weight in kilograms (kg

algol [13]

Answer:

227.2727 kilograms

Step-by-step explanation:

The tiger weight is 550 pounds, and we want to convert this value to kilograms, so we need to use the ratio between pounds and kilograms.

We know that 1 kilogram is equal to 2.2 pounds, so we can solve this problem using a rule of three:

1 kilogram is equal to 2.2 pounds,

X kilograms are equal to 550 pounds.

1/X = 2.2/500

X = 500/2.2 = 227.2727 kilograms

So the weight of the tiger in kilograms is 227.2727 kilograms.
