In most approximate way it can never be the area of the circle (Accurate area)
This is why because after creating base lines of each triangle it forms an inscribed polygon .
- Some little spaces left over each side or b_n
So
h is already approaching to r
- and b_1+b_2..b_n is approaching to the perimeter i.e 2πr
Option B
Answer:
vertex = (- 7, - 87)
Step-by-step explanation:
given a parabola in standard form : ax² + bx + c : a ≠ 0
Then the x- coordinate of the vertex is
= - 
p² + 14p - 38 is in standard form
with a = 1, b = 14, c = - 38, hence
= - 
= -7
substitute x = - 7 into the equation for corresponding value of y
y = (- 7)² + 14(- 7) - 38 = 49 - 98 - 38 - - 87
vertex = (- 7, - 87)
Answer:
37 m^2
Step-by-step explanation:
The shape can be broken down into a rectangle (on the top), two triangles (at the side) and another big rectangle (centre)
Area of one triangle
= 1/2*base*height
= 1/2*4*1
=2 m^2
Area of 2 triangles= 4m^2
Area of the small rectangle
= Length*breadth
= 1*3
= 3 m^2
Area of large rectangle in the same way
= 4*8
= 32m^2
Total area
= Sum of all the sub-areas
= 32+3+2
=37 meters^2
Answer:
x = 59/7, y = -15/7
Step-by-step explanation:
4x= 2y + 38;
2 - 3y=x
We can substitute for x in the first equation since the second equation is solved for x
4(2-3y) = 2y+38
Distribute
8 - 12y = 2y+38
Add 12y to each side
8-12y+12y = 2y+12y+38
8 = 14y+38
Subtract 38 from each side
-30 = 14y
Divide by 14
-30/14 = y
-15/7 = y
Now solve for x
2 - 3y = x
2 - 3*-15/7 = x
2 +45/7 = x
14/7 + 45/7 = x
59/7 =x
Solution :
The term 'literacy rate' provides the ability of a person who is from a definite age group can read or write.
a). 
does not determine the rate at which the variable explains another, but it explains the amount the amount of variability in one of the variables as explained by the other variable.
b). The slope given provides an expected improvement but it cannot guarantee the improvement. The value may be less or it could be more also.
The regression model provides the prediction and not the actual values.
