Answer: 3.2x = 12.8
Step-by-step explanation: Lets have x equal each box that weighs 3.2 pounds.
The expression: 3.2x = 12.8 represents that each box, x of candies will weigh 3.2 pounds and the total weight of the candies will equal 12.8 pounds of candy.
Additional: There are 4 boxes of candy, 12.8 divided by 3.2 = 4
Answer:
Step-by-step explanation:
8q=30+3q
5q=30
q=6
The given data is
t, h: 0 2 4 6 8 10
r(t), L/h: 8.6 7.9 6.8 6.4 5.7 5.3
The lower and upper estimates for the total amount that leaked may be computed as the Left and Right Riemann sums.
The shape of the graph of r versus will determine which of the two sums yields an upper or lower sum.
The plot of the graph is shown below.
The Left Riemann sum is
Sl = 2*(8.6+7.9+6.8+6.4+5.7) = 70.8 L
The Right Riemann sum is
Sr = 2*(7.9+6.8+6.4+5.7+5.3) = 64.2 L
Answer:
The lower estimate for oil leakage is 64.2 L
The upper estimate for oil leakage is 70.8 L
Answer:
Choice A: stretched horoxontally by a factor of 2 and translated up by 3 units
Explanation:
The original graph is:
y = log(x)
The modified one is:
y = log(2x) + 3
We can note that 2 changes occured:
1- A 3 has beed added to the whole gaph. This means that the curve has been moved (translated) upwards by 3 units
2- The x inside the log is miltiplied by 2. This means that the graph is stretched horizontally by the factor added (2).
Combining these two, we will find that the correct choice is A
Hope this helps :)
