First you need to know that slope-intercept form is written as y=mx+b

b= y-intercept and m= slope

I'll first start with line number one.

First, you can see that line number one crossed the y-intercept at 2.

So far we have y=mx+2

Next to find slope either do Y2-Y1/X2-X1 or M = Rise/Run

I'll do rise/run. I picked two points. (I provided a picture) An I went up 1 and went to the right 2. Giving you a slope of 1/2. If I add this to my my slope-intercept form I would get y=mx+b. Which is D.

Just do that for the rest of them.

But, here is the Code: DGBH

Let me know if anything is incorrect!

HELP!!!! thank you in advance!!

Question writer: it's customary to keep the degree sign off of the variable names in trig.

sin y = s/8

tan y = s/t

tan y = sin y / cos y

cos y = sin y / tan y

cos y = (s/8) / (s/t) = (s/8) × (t/s) = t/8

Answer: cos y = t/8, third choice

Which number line represents the solution set for the inequality-1/2x>_4

Vesna [10]

Answer:

Step-by-step explanation:

Firstly, we solve for x

-x ≥ 2 * 4

-x ≥ 8

Multiply both sides by -1

x ≤ -8

So we look at the inequality represented by this;

We can see that the correct inequality is option B;

Evaluate the integral Find the volume of material remaining in a hemisphere of radius 2 after a cylindrical hole ofradius 1 is d

algol13

You want to find the volume inside the hemisphere $x^2+y^2+z^2=4$ (i.e. inside the sphere but above the plane $z=0$ ) and outside the cylinder $x^2+y^2=1$ . Call this region $R$ .

In cylindrical coordinates, we have

$\displaystyle\iiint_R\mathrm dV=\int_0^{2\pi}\int_1^2\int_0^{\sqrt{4-r^2}}r\,\mathrm dz\,\mathrm dr\,\mathrm d\theta$

$\displaystyle=2\pi\int_1^2 r\sqrt{4-r^2}\,\mathrm dr$

$\displaystyle=-\pi\int_3^0\sqrt u\,\mathrm du$

(where $u=4-r^2$ )

$\displaystyle=\pi\int_0^3\sqrt u\,\mathrm du$

$=\dfrac{2\pi}3u^{3/2}\bigg|_0^3=2\sqrt3\,\pi$

What is the estimate of 212,514+396,705

Evgesh-ka [11]

Change 212,514 into 215,000.

Change 396,705 into 400,000.

--------

Estimate:

215,000 + 400,000 = 615,000

Therefore:

212,514 + 396,705 ≈ 615,000

A cone has a 4 radius and a 8 height what is the volume

Marta_Voda [28]

Hey there! I'm happy to help!

To find the volume of a cone, you multiply the base by the height and then divide by three.

First, we need to find the base. A cone has a circle for the base. To find the area of a circle, we square the radius and multiply it by pi (we will use 3.14).

4²=16

16×3.14= 50.24

Now, we multiply our base by the height.

50.24×8=401.92

Finally, we divide by three.

401.92÷3≈133.973 (to nearest thousandth)

Therefore, the volume of the cone is about 133.973 units cubed. If you were to use exact pi, it would be more like 134 because of all those decimals after pi!

Now you can find the volume of cones!

I hope that this helps! Have a wonderful day!
