What is the value of x and the length of segment DE?

aniked [119]

Answer:

x = 6.6; DE = 16.6

Step-by-step explanation:

Assume the diagram is like the figure below.

1. Calculate the value of x

In a right triangle, the altitude drawn from the right angle to the hypotenuse divides the triangle into two similar triangles.

Thus, ∆CDF ~ ∆FDE, and

$\begin{array}{rcl}\dfrac{CD}{DF} &=& \dfrac{FD}{DE}\\\\\dfrac{5}{9} &=& \dfrac{9}{2x + 3}\\\\5(2x + 3) & = &81\\10x + 15 & = & 81\\10x & = & 66\\x & = & \mathbf{6.6}\\\end{array}$

2. Calculate the length of DE

DE = 2x + 3 = 2(6.6) + 3 = 13.2 + 3 = 16.2

Write an equation for the graph below.

vampirchik [111]

Answer:

$f(x)= 3({2})^{x} - 3$

Step-by-step explanation:

Let the equation be of the form

$f(x)= a {b}^{x} + k$

be the equation, where k=-3 is the horizontal asymptote.

The equation now becomes:

$f(x)= a {b}^{x} - 3$ The curve passes through (0,0)

$0= a {b}^{0} - 3$

$0 = a - 3$

a=3

This implies that:

$f(x)= 3{b}^{x} - 3$

We again substitute (1,3)

$3=3{b}^{1} - 3$

$3b = 6$

$b = 2$

The required equation is

$f(x)= 3({2})^{x} - 3$
