Answer:

  16x +8h

Step-by-step explanation:

Use the given function arguments and simplify.

  \dfrac{f(x+h)-f(x)}{h}=\dfrac{8(x+h)^2-8x^2}{h}=\dfrac{8(x^2+2hx+h^2)-8x^2}{h}\\\\=\dfrac{8x^2 +16xh+8h^2-8x^2}{h}=\dfrac{16xh+8h^2}{h}=\boxed{16x +8h}

Solve for x in the given interval.<br><br> sec x= -2√3/3, for π/2 ≤x≤π
drek231 [11]

Answer:

b. x=\frac{5\pi}{6}

Step-by-step explanation:

The given function is

\sec x=-\frac{2\sqrt{3} }{3},\:\:for\:\:\frac{\pi}{2}\le x \le \pi

Recall that the reciprocal of the cosine ratio is the secant ratio.

This implies that;

\frac{1}{\cos x}=-\frac{2\sqrt{3} }{3}

\Rightarrow \cos x=-\frac{3}{2\sqrt{3} }

\Rightarrow \cos x=-\frac{\sqrt{3}}{2}

We take the inverse cosine of both sides to obtain;

x=\cos^{-1}(-\frac{\sqrt{3}}{2})

x=\frac{5\pi}{6}

What is the value of x in the equation 1.5(x + 4) - 3=4.5(x-2)
anyanavicka [17]
Hi there!

The Eqn. is :-

1.5 (x + 4) - 3 = 4.5 (x - 2)

1.5x + 6 - 3 = 4.5x - 9

Combining the like terms :-

1.5x - 4.5x = - 9 - 6 + 3

- 3x = - 15 + 3

- 3x = - 12

x = \dfrac {- 12}{- 3}

x = 4

Hence, the required answer is → x = 4

~ Hope it helps!
