Hurry i’ll make brainliest some banks charge a fee on savings accounts that are left inactive for an extended period of time. the equation y = 5000(0.98)^x represents the value, y, of one account that was left inactive for a period of x years. what is the y intercept of this equation and what does it represent?
a) 0.98 the percent of money in the account initially
b) 0.98 the percent of money in the account after x years
c) 5000 the amount of money in the account initially
d) 5000 the amount of money in the account after x years

ddd

step-by-step explanation:

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
