Answer:

Step-by-step explanation:

You have to understand two things about this question.

f(x) is a relative of y. So maybe it would help you if you wrote y = 2x^2
The second thing you have to understand is when you see a number used instead of the x, that number goes into every x on the right.

f(-3) = 2(-3)^2

f(-3) = 2 * 9

f(-3) = 18

Remember that (-3) ^2 = -3 * - 3 = 9 a positive.

Answer:

$x^{\frac{1}{2}}$

Step-by-step explanation:

we have

$(x^{\frac{1}{6}})^{3}$

Applying the rule power

$(b^{n})^{m}=b^{n*m}$

$(x^{\frac{1}{6}})^{3}=(x^{\frac{1}{6}*3})=x^{\frac{3}{6}}$

Simplify

Ty has 5 goats and 19 carrots. He gives each goat the same number of carrots, and he uses as many carrots as he can. How many ca

velikii [3]

Each goat gets 3 carrots.

After giving 3 carrots to each of the goat, 4 carrots are left with Ty in total.

Step-by-step explanation:

Here, the total number of carrots = 19

The total number of goats = 5

So, in the given condition:

19 is the DIVIDEND

5 is the DIVISOR

Now, dividing 19 by 5, we get:

19 = 5 x 3 + 4

Here, 3 = Quotient

4 = Remainder

So, by the given equation. we can say that:

Each goat gets 3 carrots.

After giving 3 carrots to each of the goat, 4 carrots are left with Ty in total.
