Answer:

$\sqrt{29}$

Step-by-step explanation:

Use the distance formula. $\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$

Plug in the coordinates into the equation. $\sqrt{(2-0)^{2}+(5-0)^{2}}$

Solve the distance formula. $\sqrt{(2)^{2}+(5)^{2}}$ --> $\sqrt{4+25}$ --> $\sqrt{29}$

Answer:

Use the formula for the distance between two points: d = √((x2 – x1)2 + (y2 – y12))

Step-by-step explanation:

d = √((5 – 0)2 + (2 – 0)2

d = √(25 + 4) = √(29) ≈ 5.385

What non-zero rational number must be placed in the square so that the simplified product of these two binomials is a binomial:

aleksandrvk [35]

The product would expand to

$(7t-10)(5t+x)=35t^2+7tx-50t-10x=35t^2+(7x-50)t-10x$

This is a trinomial, and the only way to make it a binomial is to cancel out a coefficient using our variable $x$ .

So, we can cancel either the linear term or the constant term.

In the first case, we require

$7x-50=0 \iff 7x=50 \iff x=\dfrac{50}{7}=\dfrac{49}{7}+\dfrac{1}{7}=7\dfrac{1}{7}$

In the second case, we require

$-10x=0\iff 10x=0 \iff x=0$

But $x$ must be a non-zero rational number, so this solution is not feasible.

The art teacher has 30 boxes of crayons with 16 cans in each box she gives the students 10 of the boxes to use explain how to fi

Mamont248 [21]

I'm going to assume you meant crayon instead of can:

First step is to find how many boxes she/he has left.

30 - 10 = 20

So the teacher has 20 boxes left;

Now, knowing that each box has 16 crayons, then we simply multiply the 20 by 16 to find the total number of crayons left over:

20 x 16 = 320

So the art teacher has 320 crayons left over.

Hope this helps!
