A password is 4 characters long, consisting of 2 letters and 2 numbers. The password must begin and end with a letter. If numbers can be repeated but letters cannot, how many possibilities are there?

a. 65,000
b. 60,840
C 58,500
d. 52.650

i believe the answer is d.

hope it you! : d

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

the diver is 33 feet below the surface.
