What is the value of x to the nearest tenth?<br> Need help..

satela [25.4K]

Using the tangent rule:
Tangent(angle) = Opposite leg / Adjacent leg

We will use the 23 degree angle to solve for x.

Tangent(23) = X / 6

x = 6 * tangent(23)

x = 2.5

Define an exponential function, h(x), which passes through the points (1,16) and(5, 1296). Enter your answer in the form axb^xh(

Lerok [7]

Define an exponential function, h(x), which passes through the points (1,16) and

(5, 1296). Enter your answer in the form axb^x

the equation is of the form

$y=a(b)^x$

we have

point (1,16)

For x=1, y=16

substitute

$\begin{gathered} 16=a(b)^1 \\ 16=a\cdot b \end{gathered}$

isolate the variable a

$a=\frac{16}{b}$

Point (5,1296)

For x=5, y=1,296

substitute

$1,296=a(b)^5$

substitute equation 1 in equation 2

$1,296=(\frac{16}{b})\cdot b^5$

solve for b

$\begin{gathered} \frac{1296}{16}=b^4 \\ b^4=81 \\ b=3 \end{gathered}$

Find the value of a

a=16/3

therefore

the equation is

$y=\frac{16}{3}\cdot(3)^x$
