Answer:

10.6

Step-by-step explanation:

A simple sketch of the question would give a right angled triangle. So that we can easily apply the Pythagoras theorem to determine the length of the cable required.

Let the length of the cable required be represented by x.

/Hyp/^{2} = /Adj 1/^{2} + /Adj 2/^{2}

x^{2} = 8^{2} + 7^{2}

   = 64 + 49

x^{2} = 113

x = \sqrt{113}

  = 10.63

x = 10.6

The length of the cable required is 10.6 in feet.

Can someone answer this please?
SOVA2 [1]
We can break this complicated looking shape into two more familiar ones, an icosoles triangle and a rectangle. Using the area of a triangle formula (base*height)/ 2, we get (3*6)/2=18/2= 9. Next, we multiply 8 by 16 to solve for the rectangle and get 128. We add 9 and 128 to get 137.

Your answer is 137.

Which of the following rational functions is graphed below?
lidiya [134]

Vertical asymptote:

A vertical asymptote is a value of x for which the function is not defined, that is, it is a point which is outside the domain of a function;

In a graphic, these vertical asymptotes are given by dashed vertical lines.

An example is a value of x for which the denominator of the function is 0.

In this graphic:

Dashed vertical lines at: x = -3, x = 7, thus, for x - (-3) = x+3 and x - 7 the denominator is zero.

Thus, the function graphed is:

F(x) = \frac{1}{(x+3)(x-7)}

And the correct answer is given by option C.

Please help, due soon. Find the length of each arc. Use exact answer
Anna007 [38]

Answer:

C

Step-by-step explanation:

The arc length is calculated as

arc = circumference of circle × fraction of circle

     = 2πr × \frac{285}{360}

    = 2π × 18 × \frac{19}{24}

    = 36π × \frac{19}{24} ( cancel 36 and 24 by 12 )

    = 3π × \frac{19}{2}

    = \frac{57\pi }{2} → C
