Answer:
Average rate of change = 2
Step-by-step explanation:
Find the average rate of change for f(x) = x^2 − 3x − 10 from x = −5 to x = 10.
f(-5) = (-5)^2 − 3(-5) − 10 = 25 + 15 - 10 = 30
f(10) = 10^2 − 3(10) − 10 = 100 - 30 - 10 = 60
Average rate of change:
f(10) - f(-5) 60 - 30 30
-------------------- = ------------------------------- = ----------------------- = 2
10 - (-5) 15 15
Answer:
Step-by-step explanation:
subtract 6-5.5 to get .5
and then divide .5/6 to get 0.0833
then multiply that quotient by 100 to get percentage
8.33% or 8.3% if you go to the nearest tenth
Answer: 473.85
Step-by-step explanation:
i found the multiplier which was( 100+35) / 100=1.35
351*1.35=473.85
According to the markings, BD = DC. From this fact
BD = DC
BD + DC = BC
18 + 18 = BC
BC = 36 <<<<<< Answer
