Answer:

3.14

Step-by-step explanation:

First find the circumference of the circle:

$2\pi r$ = Circumference.

$2 * \pi * 6$ = $12\pi$

Find the ratio of the angle in relation to the entire circle:

$30^o$ is what we have. So:

$\frac{30^o}{360^o} = \frac{1}{12}$

Use the ratio and multiply the circumference to find the length:

$12\pi * \frac{1}{12}$ = $\pi$

Round answer to the hundredth:

$\pi = 3.14$

The end behaviour for the polynomial function h(x)=−x3+x4−2x+1 h ( x ) = - x 3 + x 4 - 2 x + 1 is: x→−[infinity], y→−[infinity]

Goryan [66]

Answer:

$\text{As } x \to \infty, y \to \infty,$and as x \to -\infty, y \to \infty$

Step-by-step explanation:

Given the polynomial function: $h(x)=-x^3+x^4-2x+1$

To examine its end behavior, we create a table of values that we can then examine.

$\left|\begin{array}{c|c}x&h(x)\\--&--\\-4&329\\-3&115\\-2&29\\-1&5\\0&1\\1&-1\\2&5\\3&49\\4&185\end{array}\right|$

From the table, we see a repeating pattern of positive values of h(x) with h(1)=-1 being an axis of symmetry.

Therefore, as:

$x \to \infty, h(x) \to \infty\\x \to -\infty, h(x) \to \infty$

Elmer sees a flying saucer. The radius of the flying saucer is 17 feet. What is the area of the flying saucer (use 3.14 for pi a

sergiy2304 [10]

Answer:

Area of the flying saucer = $907.46 ft^2$

Step-by-step explanation:

The Flying saucer is in the shape of a circle.

$Radius= 17 feet$

Area of the circular flying saucer= $\pi *r*r$

: $\pi =\frac{22}{7} =3.14$

Area= $3.14*17*17$

Area of the flying saucer $=3.14*289\\\\ =907.46 ft^2$

So, the area of the flying saucer is $907.46 ft^2$
