1 answer:
Answer:
<u>80 gallons</u> of water will the dishwasher use to wash 10 loads of dishes.
Step-by-step explanation:
Given:
The dishwasher uses 32 gallons of water to wash 4 loads of dishes.
Now, to find the gallons of water to wash 10 loads of dishes.
So, dishwasher for 4 loads of dishes use 32 gallons of water.
1 load of dishes need =
Thus, 10 loads of dishes need =
Therefore, 80 gallons of water dishwasher use to wash 10 loads of dishes.

Answer:
-12
Step-by-step explanation:
Let b = -1 and a = -3
The average rate of change =
f(b) = f(-1) = 3(-1)^2 - 5 = 3 - 5 = -2
f(a) = f(-3) = 3(-3)^2 - 5 =27 - 5 = 22
f(b) - f(a) = -2 - 22 = -24
b - a = -1 + 3 = 2
= -24/2 = -12
Answer:
We have the equation
Then, the augmented matrix of the system is
We exchange rows 1 and 4 and rows 2 and 3 and obtain the matrix:
This matrix is in echelon form. Then, now we apply backward substitution:
1.
2.
3.
4.
Then the system has unique solution that is and this imply that the vectors
are linear independent.
