You are flying a kite at a constant height of 150 ft. The wind blows the kite horizontally to the left at a rate of 25 ft/min. At what rate is the length of the string changing when it is stretched out to 200 ft

The length of the string changing when it is stretched out to 200 ft at rate 16.535 ft/min

Step-by-step explanation:

Refer the attached figure

Height of kite = y = 150 feet

We are given that  The wind blows the kite horizontally to the left at a rate of 25 ft/min. i.e.

We are supposed to find At what rate is the length of the string changing when it is stretched out to 200 ft

z= 200

Using Pythagoras theorem :

Now to find the rate at which the length of the string changing when it is stretched out to 200 ft

Hence The length of the string changing when it is stretched out to 200 ft at rate 16.535 ft/min

step-by-step explanation:

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
