ANSWER
D. 25 feet
EXPLANATION
The height of the wall,h, the taut wire and the distance from the base of the pole to the point on the ground, formed a right triangle.
According to the Pythagoras Theorem, the sum of the length of the squares of the two shorter legs equals the square of the hypotenuse.
Let the hypotenuse ( the length of the ) taught wire be,l.
Then





Let, snake catches the mouse in t hours. Till then mouse is travelling from
( t + 1.5 ) hours.
Distance, travelled by mouse in t hours is,
.
To catch the mouse snake had to travel the same distance d in t hours.
So,

Therefore, snake will catch mouse in 1.5 hours.
By the process of elimination, it is already not the last 2, so it is 50/50 chance to get it correct, but if you know how to add, you can figure out that 1 million per year in 5 years means that it is 12 million + 5 million, which is equal to 17 million and not 14,500,000. This brings it down only to 500,000$ salary increase per year
Answer:
see the explanation
Step-by-step explanation:
we know that
The y-intercept is the value of the function when the value of x is equal to zero. Also is called the initial value of the function
I will analyze two cases
Part 1) we have

so
For x=0
substitute

therefore
The y-intercept is the point (0,0)
Part 2) we have

so
For x=0
substitute

therefore
The y-intercept is the point (0,-1)
