Ughhh...the limit formula...this should be thrown in the trash the minute you start doing derivatives :P
(-8-9(t+d)-(-8-9t))/(t+d-t)
(-8-9t-9d+8+9t)/d
-9d/d (which is -9 for any value of d as well as when d approaches zero)
-9
So the instantaneous velocity is regardless of t or delta t
Fiona and Pip win some money and share it in the ratio 6:1. Fiona gets £35 more than Pip. How much did they get altogether?
Let Pip get be x and fiona get be x+35
Ratio = 6:1
Answer:
Step-by-step explanation:
divide by 2 and square it
y+axSQUARED +bx+ c ----->(b/2)squared +d
2 ) add and subtract d to the equation
y = (axSQUARED +bx +d ) + c -d
factor the first part of the equation to match the vertex form and simplify
y= a(x-h)SQUARED + c- d
Y = a ( x - h SQUARED + k
