Answer:
Step-by-step explanation:
Write the sum of the terms in descending order.
Answer:
< 15, - 21 >
Step-by-step explanation:
Multiply each of the components of the vectors by the scalar quantity, then add corresponding components of each vector.
9u + 2v
= 9 < 3, - 1 > + 2 < - 6, - 6 >
= < 27, - 9 > + < - 12, - 12 >
= < 27 - 12, - 9 - 12 >
= < 15, - 21 >
V(barn) = 25×43×87 + 2×43:2×87
= 93525 + 3741
= 97266 ft³
Answer: x = -1 and x = 0.
Justification:
The solution of f(x) = g(x) are those values of x for which the output of f(x) is equal to the output of g(x).
The table shows that the output for f(0) is 0 and the output of g(0) is also 0.
So, 0 is one solution of the equation.
Also, the table shows that the output for f(-1) is - 1/2, as well as the output of g(-1) is - 1/2. So, -1 is other solution of the equation.
Therefore, this equation has two solutions x = - 1 and x = 0.
