Answer:

209.96

Step-by-step explanation:

we know that the circumference of the circle is equal to

C = $\pi D$

we have

$D = 64 ft$

substitute would be

$C = \pi (64) = 64\pi ft$

assume that $\pi = 3.14$

64 $64\pi = 64 * 3.14 = 200.96 ft$

Joan makes a base salary of $275 per week and a commission of 4% of sales over $1000. If she sells $1250 of merchandise this wee

Lerok [7]

Joan makes $275/week.

In addition to $275, she also makes 4 percent on sales over $1000.

So, 1250 - 1000 = 250.

Then 250(0.04) = 10.

Let t = amount of her paycheck for the week.

t = $275 + $10

t = $285

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.
