A circle has its center at (−2, 5) and a radius of 4 units. Find the equation of the circle using the Pythagorean Theorem.
Vesnalui [34]
The pythagorean theorem is only used for right triangles? however, you can find the equation with the info given. a circle is written as (x-h)^2+(y-k)^2=r^2. in this scenario, h=-2, k=5, and r=4.

Your final equation would be (x+2)^2+(y-5)^2=16

3x^2+42x+105=0 Find the solution<br><br>  <br>  <br> 0<br> 0
Nina [5.8K]

Step-by-step explanation:

I think we have to find the factors so

3x2 + 42x + 105

First we will multiply 105 by 3 = 315 then find factors of 315 which may add or subtract = 42

So 45 and 7

3x2 + 45x - 7x + 105

3x( x + 15) - 7(x - 15)

(3x - 7) and ( x - 15) are the factors

There is a problem please recheck the question

Given that S is the centroid of triangle MNO, find SQ.
DochEvi [55]

Answer:

First, we need to calculate for x. Since,

MP = PN

Thus,


3x-4 = x+4

2x = 8

x = 4


Next, we calculate for MS 

MS = 2x + 2 = 10


Since, MS = 2SQ

10 = 2SQ

Then,

SQ = 5 units


Therefore, the correct answer is B.

Write and simplify an expression to model the relationship expressed in the situation below.
spayn [35]
V(p) = x-n, where V(p) is the volume after the boxes have been together, x is the volume of the larger box, and n is the volume of the smaller box.
x = 15 cm x 25 cm x 20 cm = 7500 cubic centimeters (cm^3)
n = 10 cm x 10 cm x 10 cm = 1000 cm^3
V(p) = 7500 - 1000 = 6500 cm^3
So your answer is 6500 cubic centimeters.
