The height of the pole = 129.3 ft
sin 36° = height of pole/ hypotenuse
hypotenuse = 220 ft
the height of the pole = 220 sin 36° = 129.3 ≈ 129 ft
Hello,
2x^3+14x^2+6x+42=2x^2(x+7)+6(x+7)
=(x+7)(2x²+6)
=2(x+7)(x²+3) in IR.
or In C 2(x+7)(x-i√3)(x+i√3)
Answer:
160-128=32
Step-by-step explanation:
distribute what is in the parentheses
Answer:
128.67 ft
Step-by-step explanation:
Let the height of the tower be x feet.
In general, the derivative of a single term Ax^(n) is A n x^(n-1) .
And the derivative of a sum of many terms is the sum of the derivatives
of the individual terms.
Using these two rules, the derivative (with respect to 'x') of the expression
in the question is . . .
<em> Y' = -21x² - 16x + 6</em>
