Answer:

Fred.

Started hang gliding at a height of 700 ft and descends 15 feet every seconds

Gene

Started hang gliding at a height of 575 ft and descends 10 feet every seconds

Step-by-step explanation:

The function that models Fred's hang gliding is $f(x)=-15x+700$

The initial value is 700 feet. This Fred was 700 feet above see level before he starts descending.

The rate of descent is -15 ft/s. This means Fred descends 15 feet in one second.

From the table the initial height is 575 ft. This means Gene was 575 feet above sea-level at the beginning of the hang gliding.

The rate of descent is $\frac{565-575}{1-0} =-10$ ft/s.

This means that in every seconds, Gene descends 10 feet.

How are comparisons between negative numbers different than comparisons between positive numbers?

lara [203]

On a number line, numbers always increase to the right and decrease to the left. Numbers to the right are greater than numbers to the left and numbers to the left are less than numbers to the right.

The perimeter of a rectangle is 24. If the length is 5 times the width, what is the area?

KATRIN_1 [288]

Answer: Area is 20

Step-by-step explanation:

Perimeter of a rectangle is 24

Let the length be x

Let the breadth be Y

Length is 5times the breadth

I.e

X=5y

Formula for perimeter of a rectangle is

2(length + breadth)

= 2(x+y)

Substitute for x=5y

2(5y+y)=24

2(6y)=24

6y=24/2

6y=12

Y=12/6

Y=2

Breadth = 2

Since length =5y

Length=5(2)

Length = 10

Area of a rectangle = length × breadth

Area= 10×2

Area = 20

Area of the rectangle is 20

Find the limit of the function by using direct substitution. limit as x approaches one of quantity x squared plus three x minus

ivann1987 [24]

Answer:

Limit = -1

Step-by-step explanation:

We are given the following function:

$x^2 + 3x -1$

We are to calculate the limit of this function as x approaches zero.

For that, we will use direct substitution method and substitute the x with 0 in the given function to calculate its limit as follows:

$x ^ 2 + 3 x - 1$

$( 0 ) ^ 2 + 3 ( 0 ) - 1 = - 1$

Therefore, the limit is -1.
