Circumcenter, Incenter, Orthocenter vs Centroid. Circumcenter: circumcenter is the point of intersection of three perpendicular bisectors of a triangle. Circumcenter is the center of the circumcircle, which is a circle passing through all three vertices of a triangle.
Answer:
4,784ft^2
Step-by-step explanation:
Well in this case we will just use the square and triangle area formulas instead of the pyramid surface area formula.
So if the base is a square then the area is 32*32 which is 1,024.
Now for the trangle, the area of a triangle b*h/2.
So b*h is 47*32 which is 1,504.
So 1,504/2 is 752.
So 752 is the area of 1 triangle and we have 4 so 5*752 is 3,760.
So 3,760 + 1,024 is 4,784.
So the total SA if the pyramid is 4,784ft^3.
Answer:
7.2 cm
Step-by-step explanation:
For the similar triangles, the ratio of the length of the bottom side to the right side is the same:
bottom/right = (x cm)/(6 cm) = (12 cm)/(10 cm)
x cm = (6 cm)(12/10) = 7.2 cm
_____
Technically, x = <em>7.2</em>, not <em>7.2 cm</em>.
Answer:
.05
Step-by-step explanation:
The exponential growth formula is y = ab^x, where b=rate of growth, a=initial value, x=time interval.
Our equation is
P(t) = 18(1.05)^t
We are multiplying our 18 by 1.05 every day--that means t's increasing, and it's growth. Anything lower than 1 (like .95) means decay, and anything over means growth.
1.05 - 1 = .05
<u>So every day the number grows by a factor of .05.</u>
