Degree 2 = quadratic
Degree 3 = cubic
Degree 4 = quartic
Degree 5 = quintic
-2x^2 ( -5x^2 + 4x^3 ) = 10x^4 - 8x^5 = -8x^5 + 10x^4
The legs = 14 units
The area is the product of the legs / 2.....so....the area is
[ 14 * 14 ] / 2 = 196 / 2 = 98 units^2
2x^2 -3x + 2 = 0
a = 2, b = -3, c = 2
x = ( -(-3) ±√[ (-3)^2 - 4(2) (2) ] ) / [2*2 ]
x = ( 3 ±√ [ 9 - 16 ] ) / 4
x = ( 3 ± i√ 7 ) / 4
Correct choice, NSS !!!
Each leg is 14√2 / √2 = 14 units
Their are 39.37 inches in a meter....there are 12 inches in a foot
So....the number of feet in a meter is 39.37 / 12 ≈ 3.28 ft in a meter
So 5.92 m x [ 3.28 ] ≈ 19.42 ft
And since 3ft = 1 yard, we can divide the first result by 3 to get the number of yards in 5.92m =
19.42 / 3 ≈ 6.47 yards
Label the vertices as {A, B,C,D,E,F,G,and H}
So, we want all the sets that consist of choosing any 3 of the 8 without regard to order...
So
C (8,3) = 56 triangles
This is a right triangle.....the circumcenter will be at the midpoint of the hypotenuse
The endpoints of the hypotenuse are (-1, -1) and (5, 1)
So the midpoint - and circumcenter - is [ ( 5 - 1) / 2 , (1 - 1 ) / 2 ] = ( 2 , 0)
26 / 40 = 13 /20
Multiply numerator/ denominator by 5
[ 13 ^ 5 ] / [ 20 * 5 ] =
65 / 100 =
65%
3x^2 - 15x + k
The x coordinate of the vertex is 15 / [ 2*3] = 15 / 6 = 5/2
So....we want to solve this for k
3 (5/2)^2 - 15 (5/2) + k = 1
75/4 - 75/2 + k = 1
-75/4 + k = 1
k = 1 + 75/4 = 79/4
