Answer:

$8u+ 17 = 17 \\ 8u = 17 - 17 \\ 8u = 0\\ u = \frac{0}{8} \\ \boxed{u = 0}$

<h3><u>u=0</u> is the right answer.</h3>

You would try to isolate u first. to do this, subtract 17 from each side. you should have 8u=0. then, divide 8 from each side. you should have u=0.

The ratio of sugar to flour in the recipe is 1 to

Sveta_85 [38]

Answer:

10 flour

Step-by-step explanation:

1:2

5:x all you have to do is multiply by 2, sense the ratio is 1:2, flour will always be 2 times greater than sugar. so the answer is 5 x 2 =10

Given an undirected graph G= (V, E) determined by the adjacency matrix as follows:

lara [203]

The degree of a vertex is defined as the number of edges that touch the vertex. The (i, j)-th entry of the adjacency matrix tells you whether vertex i touches vertex j (1 if yes, 0 if no). Then the degree of vertex i is equal to the sum of the i-th row in the adjacency matrix.

• vertex 1 : degree = 0 + 1 + 0 + 0 + 1 = 2

• vertex 2 : degree = 1 + 0 + 1 + 1 + 1 = 4

• vertex 3 : degree = 0 + 1 + 0 + 1 + 0 = 2

• vertex 4 : degree = 0 + 1 + 1 + 0 + 1 = 3

• vertex 5 : degree = 1 + 1 + 0 + 1 + 0 = 3

So, the correct answer is A. 2.

An oil refinery is located on the north bank of a straight river that is 2 km wide. A pipeline is to be constructed from the ref

Mazyrski [523]

Answer:

7.85 km

Step-by-step explanation:

Let x represent the distance from the refinery to point P. Then the distance under the river from point P to the storage tanks is ...

√(2² +(9 -x)²) = √(x² -18x +85)

In units of $200,000, the cost of the pipeline will be ...

c = x + 2√(x² -18x +85)

The derivative with respect to x is ...

dc/dx = 1 +(2x -18)/√(x² -18x +85)

When we set this to zero, we can get the equation ...

√(x² -18x +85) +(2x -18) = 0

And this can be rewritten as ...

3x^2 -54x +239 = 0

which has solution

x = 9 -(2/3)√3 ≈ 7.8453

Point P should be located about 7.85 km from the refinery.

_____

It is interesting to note that the angle the pipe makes with the riverbank is given by arccos(1/2), where the 1/2 is the ratio of overland to under-river costs. That angle is 60°, so the distance along the riverbank from the storage facility to point P is 2cot(60°) = (2/3)√3 ≈ 1.1547 km. You will recognize this as the value subtracted from 9 km in the solution above.

This "angle solution" is the generic solution to this sort of problem where the route costs are different and part of the route is along the edge of the higher-cost path.
