X1 = -1
y1 = 4
point-slope form is y - 4 = 2(x+1)
Lets look at x^2+8x-3
the degree of the polynomial is the highest power of the exponent of the placeholders
x^2, power=2
8x, power=1
-3, power=0 (-3x^0=-3)
so if you had
x^89+x^8-8x-2^100
degree is 89 since that is highest power of the placeholders
The area of the triangle is 4.75.
You times 1.9 (the height) and 5 (the base) then divide the product by 2.
A = 1.9km x 5km / 2
The square root of 81/100
equals...
9/10
Good Luck! :)
