Answer: there would be 52 yellow marbles

Step-by-step explanation:

Ok we know that there is 65 marbles in total? Right? So then we’d take 65 and think, what could we divide this by and start guessing and estimating numbers. (I guessed 5, one because it’s divisible by 65, two there is 5 times more yellow marbles than red marbles.) So 5 divided by 65 is 13. But, in order to find the amount of yellow marbles, we need to subtract the whole number by the amount of red marbles. (So 65-13 =?) if you subtract that you get 52 yellow marbles.  :)

How to find area of parallelogram with coordinates of verticles?
ExtremeBDS [4]
You find a parallelogram area by this formula:
A=b\cdot h
Where b is its base and h, its height.
You get b's value applying distance between two points formula.
If A and B points form the base:
A(x_1,y_1)\;\;\;\;B(x_2,y_2) \\  \\ 
d_{AB}= \sqrt{(x_1-x_2)^2+(y_1-y_2)^2} =b

And h is the perpendicular distance between both bases.

Simplify the following radicals. 1. √16 2. √17 3. √18 4. √19 5. √20
Pavel [41]

Answer:

Step-by-step explanation:

1) \sqrt{16}= \sqrt{4*4}=4\\\\\\2)  \sqrt{17}

This is the simplest form as 17 is a prime number.

3)  \sqrt{18}= \sqrt{2*3*3} = 3 \sqrt{2}\\\\\\4) \sqrt{19}

19 is a prime number. so it is the simplest form.

5)  \sqrt{20}= \sqrt{2*2*5}=2 \sqrt{5}

Which function has a vertex at the origin?
dlinn [17]

Answer:

  (d)  f(x) = -x²

Step-by-step explanation:

For the vertex of the quadratic function to be at the origin, both the x-term and the constant must be zero. That is, the function must be of the form ...

  f(x) = a(x -h)² +k . . . . . . . . . . vertex form; vertex at (h, k)

  f(x) = a(x -0)² +0 = ax² . . . . . vertex at the origin, (h, k) = (0, 0)

Of the offered answer choices, the only one with a vertex at the origin is ...

  f(x) = -x² . . . . . a=-1
