In a science-fiction story, a spaceship travels 3 times faster each minute than it traveled during the minute before. If the shi
JulijaS [17]

The expression is:

speed(minutes)=3\frac{km}{h} ^{minutes} \\\\speed(15minutes)=(3^{15})\frac{km}{4} =14348907\frac{km}{g}

Why?

From the statement we know that the spaceship travels 3 times faster each minute that it traveled during the minute before, it can be expressed using an exponential function, its base will be the starting speed (during the first minute).

The expression will be:

speed(minutes)=(3^{minutes})\frac{km}{h} \\\\speed(15minutes)=(3^{15})\frac{km}{h}=14348907\frac{km}{h}

Have a nice day!

Which of the given values is a solution to the equation 8c+3=−40c−10?
solniwko [45]

Answer:

\boxed{\bold{C \ = \ \frac{-13}{48}  \ or \ -0.27083333333}}

Explanation:

8c + 3 = −40c − 10

[ Step 1: Add 40c to both sides ]

8c + 3 + 40c = −40c − 10 + 40c

48c + 3 = −10

[ Step 2: Subtract 3 from both sides ]

48c + 3 − 3 = −10 − 3

48c = −13

[ Step 3: Divide both sides by 48 ]

48c / 48 = −13 / 48

C = -13 / 48 or -0.27083333333
