You should place 4 red beads and 10 yellow beads into the container. This satisfies both, the ratio and the amount of beads in each container

What does the dashed line represent in a parabola

Nataly_w [17]

If the inequality symbol is ≤ or ≥ , then the region includes the parabola, so it should be graphed with a solid line. Otherwise, if the inequality symbol is < or > , the parabola should be drawn with a dotted line to indicate that the region does not include its boundary. Example: Graph the quadratic inequality.

One factor of 2x^2-32y^2 is

Sergeeva-Olga [200]

Factor the following:
2 x^2 - 32 y^2
Factor 2 out of 2 x^2 - 32 y^2:
2 (x^2 - 16 y^2)
x^2 - 16 y^2 = x^2 - (4 y)^2:
2 (x^2 - (4 y)^2)
Factor the difference of two squares. x^2 - (4 y)^2 = (x - 4 y) (x + 4 y):
Answer: 2 (x - 4 y) (x + 4 y)

Use the arc length formula to find the length of the curve y = 2 − x2 , 0 ≤ x ≤ 1. Check your answer by noting that the curve is

Lina20 [59]

By using the arc length formula, we will see that the length of the curve is L = 1.48

<h3>How to use the arc length formula?</h3>

Here we have the curve:

y = 2 - x^2 with 0 ≤ x ≤ 1

And we want to find the length of the curve.

The arc length formula for a curve y in the interval [x₁, x₂] is given by:

$L =\int\limits^{x_2}_{x_1} {\sqrt{1 + \frac{dy}{dx}^2} } } \, dx$

For our curve, we have:

dy/dx = -2x

And the interval is [0, 1]

Replacing that we get:

$L =\int\limits^{1}_{0} {\sqrt{1 + (-2x)^2} } } \, dx\\\\L \int\limits^{1}_{0} {\sqrt{1 + 4x^2} } } \, dx\\$

This integral is not trivial, using a table you can see that this is equal to:

$L = (\frac{Arsinh(2x)}{4} + \frac{x*\sqrt{4x^2 + 1} }{2})$

evaluated from x = 1 to x = 0, when we do that, we will get:

$L = \frac{Arsinh(2) + 2*\sqrt{5} }{4} = 1.48$

That is the length of the curve.

Help please!!!!!!!!!!

Scorpion4ik [409]

Answer:

H. 1/9.

Step-by-step explanation:

The area of a circle is calculated by solving for π $r^2$ .

The smallest circle has an area of π $1^2$ = π * 1 = π.

The middle ring will then have an area of π $2^2$ - π = π * 4 - π = 4π - π = 3π.

The largest ring will then have an area of π $3^{2}$ - π $2^{2}$ = 9π - 4π = 5π.

5π + 3π + π = 9π

So, the probability of hitting the innermost circle will be π / 9π = 1 / 9.

Your answer is H. 1/9.

Hope this helps!

Find the slope of the line. Describe how one variable changes in relation to the other. How did you find this?

zlopas [31]

Answer: B. -2/3 the amount of water decreases every 3 minutes!

Step-by-step explanation:

B because it starts with 14 gallons with 0 minutes and the slope goes go down 2 and run 3 so therefore, the answer is B because from 14 gallons and 0 minutes it goes to 3 minutes 12 gallons and 6 minutes and 10 gallons so it decreases 2 gallons everything 3 minutes!
