Drawing this square and then drawing in the four radii from the center of the cirble to each of the vertices of the square results in the construction of four triangular areas whose hypotenuse is 3 sqrt(2). Draw this to verify this statement. Note that the height of each such triangular area is (3 sqrt(2))/2.
So now we have the base and height of one of the triangular sections.
The area of a triangle is A = (1/2) (base) (height). Subst. the values discussed above, A = (1/2) (3 sqrt(2) ) (3/2) sqrt(2). Show that this boils down to A = 9/2.
You could also use the fact that the area of a square is (length of one side)^2, and then take (1/4) of this area to obtain the area of ONE triangular section. Doing the problem this way, we get (1/4) (3 sqrt(2) )^2. Thus,
A = (1/4) (9 * 2) = (9/2). Same answer as before.
Answer:
x^2+x+1
Step-by-step explanation:
(3x^2+4x−1)+(−2x^2−3x+2)
Combine like terms
3x^2-2x^2+4x-3x-1+2
x^2+x+1
Answer:
C
Step-by-step explanation:
X vertex = (0, - 3)
ax² + bx + c = y
0.x² + b.0 + c = - 3
c = - 3
Then:
The graphic of g(x) is the a one is negative, because the curve is below.
Then:
g(x) = - x² - 3

Answer:
T=3.3 HOURS AFTER THEY LEAVE THEY WILL BE 363 MILES APART
Step-by-step explanation:

The initial number was 3.915 and doubled to 7.830
Regression equation y = 3. 915(1. 106)x
7.830=3.915(1.106)D
we have to find the value of D.
This is the concept of algebra,
suppose the initial number was x, and the new number is 2x.
The constant rate of growth is r and time is D,
Then,
what is the function representing growth?
from our choices the equations that represents the information above will be:
7.830=3.915(1.106)D
and
7.830=3.915(2)D
Therefore
from both equations we see the initial number was 3.915 and doubled to 7.830
