Answer:
Average rate of change = 20.2
Rate of change at the left endpoint : f' (5) = 4t = 20
Rate of change at the right endpoint : f' (5.1) = 4*5.1 = 20.4
Step-by-step explanation:
The average rate of change of the function
F(t) = 2t^2 - 1 , [ 5,5.1 ]
solution
= 
= [ 2 ( 26.01 - 25 ) / 0.1 ]
= 2.02 / 0.1 = 20.2
Rate of change at the left endpoint : f' (5) = 4t = 20
Rate of change at the right endpoint : f' (5.1) = 4*5.1 = 20.4
Answer:
we conclude that the 'bait and switch' technique is not a promotional tactic used by a seller.
Hence, 'a' is the correct option.
Step-by-step explanation:
From the given options, the 'bait and switch' technique is not a promotional tactic used by a seller.
'Bait and switch' is a deceptive sale practice using which the sells try to attract (bait) the customers by offering attractive prices on certain items, but when the customers tend to go to the shop to buy the items, they witness the unavailability of the goods, or find the prices go higher compared to what they had been offered.
Now, since the customers are already present at the shop, the sellers try to pressurize the customer so that they could buy something else.
Therefore, we conclude that the 'bait and switch' technique is not a promotional tactic used by a seller.
Hence, 'a' is the correct option.
Answer:

Answer:
It's yes
Step-by-step explanation:
7x-y=9
3x-y=5 (multiply by -1 both sides of the equation)
7x-y=9
-3x+y=-5 (now add both equations)
7x-3x-y+y=4
4x=4 (divide by 4 both sides of the equation)
x=1
y=3x-5=3×1-5=-2
y= -2
answer: x=1, y=-2
