5 0

Answer:

D) f(x) = 5(4)ˣ

Explanation:

(x, y) = (2, 80)

Check by inserting x = 2

A) y = 4(x)⁵ = 4(2)⁵ = 128

B) y = 5(x)⁴ = 5(2)⁴ = 80  - passes

C) y = 4(5)ˣ = 4(5)² = 100

D) y = 5(4)ˣ = 5(4)² = 80 - passes

An exponential equation is in a(b)ˣ format, so only f(x) = 5(4)ˣ is an exponential equation which passes the point (2, 80)

Explain why an elevation less than -5 feet represents a distance from sea level greater than 5 feet. ​
Morgarella [4.7K]

The elevation represents a distance from the sea level greater than 5 feet,

because the original description specifies a distance greater than 5 feet

below sea level.

Reasons:

The elevation given as a distance is the height or distance above sea level.

In the above description, elevation is a vector, given that it has both

magnitude (distance) and direction (above sea level).

Distance is a scalar quantity, that has only a magnitude that specifies the

space covered during motion.

An elevation of less than -5 feet indicates that distance of the location

above sea level is less than -5 feet, which is the same as; the distance of

the location  below sea level is greater than 5 feet.

  • Less than -5 feet above sea level = Greater than 5 feet below sea level

Therefore;

  • An elevation of less than -5 feet represents a distance from (below) sea level greater than 5 feet

Please show steps when solving this.

\frac{240 inches}{1 minute}

We're going to change one unit at a time. Let's start with inches to feet. There are 12 inches in 1 foot. Divide 240 by 12 or multiply by 1/12.

\frac{240 inches}{1 minute} * \frac{1 foot}{12 inches}=\frac{20 feet}{1 minute}

Next, let's do the time using the same idea. Remember that there are 60 minutes in 1 hour.

\frac{20 feet}{1 minute} * \frac{60 minutes}{1 hour} = \frac{1200feet}{1hour}

Answer: 1200 feet per hour

Hope this helps!
