Step-by-step explanation:

The question missing attachment (incomplete)

But the question said how far up does the ladder reach on the building?

See the attachment

Let the tita be 60° and the height of the building be 50 meters

Now

Opposite/hypotenuse = sin(tita)

50/x = sin60°

Cross multiply to find x

x = 50/sin(60°)

x= 50/0.8660

x=57.7 meters

olganol [36]
We calculate for the taxable income by subtracting the tax free allowance from the gross income.

          Taxable income = Gross income - tax free allowanc
           Taxable income = (£12,000 - <span>£6,475)
                                    = </span><span>£5,525

Hence, the taxable income is equal to </span><span>£5,525.

Net income: 
This would be equal to the gross income minus the amount of taxes to be paid.
 
                 Net income = Gross income - amount of tax to be paid
                 Net income = (</span><span>£12,000) - (0.20)($5,525)
                 Net income = $10,895

Therefore,

Find an n-degree polynomial function with real coefficients satisfying the given condition.
kolezko [41]

In all cases, if f has real coefficients, then any complex roots occur in conjugate pairs, so if a+bi is a root, then so is a-bi. Also, by the fundamental theorem of algebra, if r_1,\ldots,r_n are roots to f, then for some constant a\in\mathbb R,

f(x)=a(x-r_1)\cdots(x-r_n)

1. If n=3 and f(3)=f(2i)=0, then

f(x)=a(x-3)(x-2i)(x+2i)=ax^3-3ax^2+4ax-12a

Given that f(-1)=50, we have

f(-1)=a(-1-3)(-1-2i)(-1+2i)=-20a=50\implies a=-\dfrac52

\implies\boxed{f(x)=-\dfrac52x^3+\dfrac{15}2x^2-10x+30}

2.

f(x)=a(x-4)(x-(-5+2i))(x-(-5-2i))=a x^3 + 6 a x^2 - 11 a x - 116 a

With f(2)=-636, we have

f(2)=a(2-4)(2+5-2i)(2+5+2i)=-106a=-636\implies a=6

\implies\boxed{f(x)=6x^3+36x^2-66x-696}

The rest are done in the same exact way.
