Answer:
A four mile ride would cost $10
Step-by-step explanation:
Let T be the total ride cost
Let M be the amount of miles driven
T = 1.75M + 3
You can now sub in any distance in miles into the equation, but for this instance lets sub in 4 miles
T = 1.75*(4) + 3
T = 7 + 3
T = 10
Therefore, a four mile ride would cost 10 dollars
Answer:
2 seconds
Step-by-step explanation:
The formula h = -16t^2 +vt +s gives the vertical height (in feet) at time t (in seconds) for an object with an initial vertical velocity (in ft/s) of v and an initial height (in ft) of s. The problem statement tells us the ball's initial velocity is v=34 and the initial height is s=4.
Then the equation is ...
h = -16t^2 +34t +4
We want to find the value of t when h=8. There will be two solutions, one when the ball is going up, and the other when the ball is coming down. We are interested in the second solution.
8 = -16t^2 +34t +4
16t^2 -34t +4 = 0 . . . . . subtract the right side of the equation to put it into standard form
(16t -2)(t -2) = 0 . . . . . . factor the equation
Solutions are values of t that make the factors zero:
t = 2/16 or t = 2
It takes 2 seconds for the ball to come down to meet Mike's head.

Answer: ![y^2-100.](https://tex.z-dn.net/?f=y%5E2-100.)
Step-by-step explanation:
if we have a square with sides 'y' units,
then, its breadth = length = y
If we add 10 to one side it will become (y+10) (longer one) and subtract 10 from another, then it will become (y-10) (shorter one).
Area of rectangle = breadth x length
So, area of rectangle ![= (y+10)(y-10)](https://tex.z-dn.net/?f=%3D%20%28y%2B10%29%28y-10%29)
![= y^2-10^2=y^2-100\ \ \ \ \ [(a-b)(a+b)=a^2-b^2]](https://tex.z-dn.net/?f=%3D%20y%5E2-10%5E2%3Dy%5E2-100%5C%20%5C%20%5C%20%5C%20%5C%20%5B%28a-b%29%28a%2Bb%29%3Da%5E2-b%5E2%5D)
Hence, the new area as a polynomial = ![y^2-100.](https://tex.z-dn.net/?f=y%5E2-100.)
