Answer:

Step-by-step explanation:

$f(t)=2(0.4)^t$

f(-2) → put t = -2 to the equation of the function:

$f(-2)=2(0.4)^{-2}=2\left(\dfrac{4}{10}\right)^{-2}=2\left(\dfrac{2}{5}\right)^{-2}$

Use $a^{-n}=\left(\dfrac{1}{a}\right)^n$

$f(-2)=2\left(\dfrac{5}{2}\right)^2=2\left(\dfrac{25}{4}\right)=\dfrac{25}{2}=12.5$

WILL GIVE BRAINLIEST<br><br> how to to convert numbers from stranded form to scientific notation

kaheart [24]

Hello there!

Soo..to convert a number from standard notation to scientific notation you first have to write a decimal point in the number so that there is only one digit to the left of the decimal point. Sooo for example if u had 240,000 you would put the decimal after the 2 (2.40000)

Hope this helped and have a great day!!

Goodluck (:
