Answer:
(D)Multiply the previous value by 2
Step-by-step explanation:
From the given table, we observe that the negative power of 2 reduces by 1 at each step.
Therefore, as the exponents increase, we multiply the previous value by 2 to obtain the next value.
The correct option is D.
She made a mistake when she subtracted x1 from x2.
Step-by-step explanation:
Step 1 :
a)
The formula used by Lorena to calculate the slope between 2 points is correct
So the statement given in option 1 is not the reason for her mistake
Step 2:
b)
She has taken the fourth and fifth point and correctly used the x and y co ordinates to calculate the slope
Hence the statement in second option is not true
Step 3:
c)
While calculating the slope the denominator is -2 - (-4) . This gives 2 as the answer. But she has made a mistake in this subtraction giving -6 as the answer.
Hence she has made a mistake in subtracting x1 from x2 and this statement is true
Step 4:
d)
She has not made any mistake in subtracting y1 from y2. Hence this statement is not true
To answer this, write a system of equations and use one to solve the other.
b + 2c = 2000 or b = 2000 - 2c (substitute this in for b in the 2nd equation)
2b + 3c = 3300
2 (2000 - 2c) + 3c = 3300
4000 - 4c + 3c = 3300
4000 -c = 3300
-c = -700
c = 700 calories
He burned 700 calories per hour canoeing and 600 calories per hour playing basketball (2000 - 2 x 700).
