Write the standard equation of a circle with center (−9, −4) and radius calculator

Mathematics

The equation of a circle is (x-h)²+(y-k)²=r², (h,k) is the center of the circle, r is the radius.
in this case, if the radius is √5, the equation is (x+9)²+(y+4)²=5

(x+9)^2+(y+4)^2=0
Because the radius is not given.

Hello!

First you have to find the volume of the cube

To do this we use the equation a^3

a is a side length

24^3 = 13824

The maximum pyramid can have a maximum side length of 24 and a maximum height of 24 since that is what the cube measurements are

The equation for the volume of a square pyramid is

a^{2}  \frac{h}{3}

a is side length
h is height

put in 24 for the values

24^{2}  \frac{24}{3}

Square the 24

576 \frac{24}{3}

Divide

576 * 8 = 4608

The answer is B) 4608 cubic centimeters

Hope this helps!

What is the midpoint (-4,0) and (10,7)?
mestny [16]
We first use midpoint formula
X1+X2 divided by 2 we want x for midpoint.
Y1+Y2 divided by 2 we want Y for midpoint
10-4 divided by 2 =3
7-0 divided by 2 =7/2
therefore midpoint= (3;7/2)

Which of the following is a trinomial with a constant term? A. 4x4 + 2x2 - 2x B. -3 + 4x4 C. 2x2 - 5 + x D. 4x4 - 3x2 + x
castortr0y [4]
C. 2x² - 5 + x i<span>s a trinomial with a constant term
</span>That polynomial has three terms: (2x²<span>), (-5) and (x) 
Term (-5) </span><span>contains no </span>variable, so <span>this is a constant term.</span>

How can I use the golden ratio? Need this answer, stop putting false please.
natulia [17]

Hey, this is photography right?

Step 1: Evaluate the scene

Exactly how you use the golden ratio depends on the scene in front of you. Composition techniques are there to help you think about the scene instead of just pointing and shooting.

Step 2: Determine whether to use the golden ratio or the golden spiral (or even the Rule of Thirds)

Next, choose between the golden spiral and the phi grid. You can’t contort a straight object to fit inside a spiral, so if your scene has great leading lines, try the phi grid.

Step 3: Imagine the overlay and shoot

Imagining a complex spiral aligned over your photo can be tricky at first. If you simplify the concept, it’s a bit easier to manage.

First, check and see which grid overlays your camera has built-in by viewing the options in settings. If your camera has a phi grid or spiral option, turn that feature on. Most will have the Rule of Thirds. Even when that isn’t the composition guide you are using, it’s helpful to enable that feature.

Step 4: Edit

Picturing the phi grid or golden ratio spiral as you shoot is one thing, but what if you want that exact 1.618 magic number? Thankfully Photoshop  (and several other photo editors) have tools for that.

Hope this helped!
