A Japanese garden has a circular koi pond in the middle that has a radius of 3 feet. A rectangle with length of 16 feet and widt

Mariulka [41]

Answer:

first, find the area of the circle cut.

r= 3 feet

π=3.14

area of a circle= πr²= 3.14×3×3= 28.26 sq.feet

Now, find the area of the rectangle and subtract it by the area of the circle.

area of rectangle = l×b

length of the rectangle= 16 feet

breadth/width of the rectangular garden= 14 feet

area= 16×14= 224 sq. feet

now, area of the garden surrounding the koi pond= 224-28.26

=195.74 sq. feet

A ball is thrown in the air from a ledge. Its height in feet is represented by

Genrish500 [490]

check the picture below.

$\bf \stackrel{f(x)}{0}=-16(x^2-6x-7)\implies 0=x^2-6x-7 \\\\\\ 0=(x-7)(x+1)\implies x= \begin{cases} \boxed{7}\\ -1 \end{cases}$

it cannot be -1, because is a seconds amount after moving.

The function. In the graph is f(x) =

Tanya [424]

Answer:

$x^3-2x^2-5x+6$

Step-by-step explanation:

We have been given a graph of the function f(x).

Now we need to use that graph to find the equation of the graph and match with the correct choice from the give choices:

$x^4-2x^2+5x+6$

$x^3-2x^2-5x+6$

$x^3-2x^2+5x+6$

$-x^4-2x^2+5x+6$

We see that graph has end points in opposite direction then the degree of polynomial must be ODD.

Available degrees are 3 and 4. Degree 3 is odd so it is choice B or C.

Only $x^3-2x^2-5x+6$ satisfies the given points from graph.

Hence correct choice is $x^3-2x^2-5x+6$ .
