P=44+66+88/2=198/2=99
With Heron formula:
S=root 99*(99-44)(99-66)(99-88)=root 99*55*33*11=root 1976535= 1405.8929.....=1405.9

To find the distance between her home and her latest position:

According to the question, the diagram is,

Consider the right triangle,

AB=120 km

BC=50 km

To find AC:

Using Pythagoras theorem,

$\begin{gathered} AC^2=AB^2+BC^2_{} \\ =120^2+50^2 \\ =14400+2500 \\ =16900 \\ =130\text{ km} \end{gathered}$

Hence, the distance between the new position and her home is 130 km.

first question what is the starting point?Exponential equation for the black bird: g(x) = 2^x-8 + 1King Pig is located at (11,9)

goblinko [34]

Given the exponential function:

$g(x)=2^{x-8}+1$

The starting point is found when x = 0.

So, let's substitute x by 0.

$\begin{gathered} g(0)=2^{0-8}+1 \\ g(0)=2^{-8}+1 \\ g(0)=0.0039+1 \\ g(0)=1.004 \end{gathered}$

Answer: The starting point is (0, 1.004).

You deposit $3000 in an account earning 4% interest compounded continuously. How much will you have in

V125BC [204]

Answer: $3,664.21

Formula: $A=Pe^{rt}$

P = principle/original amount = $3000
r = rate of interest = 4% = 0.04
t = time period (in years) = 5
A = the new amount
e = Euler's number ≈ 2.718...

Substitute in the values:

$A=(3000)e^{(0.04)(5)} =(3000)e^{0.2} =(3000)(1.2214)=3664.208$

<u>Approximately $3,664.21</u>
