Find all constants α such that the vectors (α, 4) and (α, 5) are parallel.

Mathematics
1 answer:
Anna [14]3 years ago
7 0

Answer:

\alpha_{2} = \frac{5}{4}\cdot \alpha_{1}, for all \alpha_{1} \in \mathbb{R}

Step-by-step explanation:

Vectors are parallel to each other if:

\vec u = \beta \cdot \vec v

(\alpha_{2}, 5) = (\beta\cdot \alpha_{1}, \beta \cdot 4)

The value of \beta is:

\beta = \frac{5}{4}

Then, the following relationship is found:

\alpha_{2} = \frac{5}{4}\cdot \alpha_{1}, for all \alpha_{1} \in \mathbb{R}

Which algebraic expression represents "one-third of the number s, plus t"?
TiliK225 [7]

Answer:

A) s/3 +t

Step-by-step explanation:

To represent 1/3 of a number, we can simply divide this number by 3, meaning if s is the number, 1/3 of s would be s/3. Now to add t all we have to do is + t, making our answer s/3 + t

A pond at a hotel holds 4,290 gallons of water.
Kisachek [45]

Answer:

55 hours

Step-by-step explanation:

Write the problem as an equation.

4290-78x=0

Where 'x' is each hour the pond is being drained.

Then, solve.

4290=78x        Add 78x to each side of the equation

55=x                 Divide both sides by 78

The volume of a cylinder is 1.54 litre. If the height is 20 cm ​
11111nata11111 [884]

Answer:

Radius = 4.95 cm

Step-by-step explanation:

I am assuming you need the radius of the base of the cylinder.

Volume = 1.54 * 1000 = 1540 cm^3

Volume = πr^2h so:

1540 =  π*r^2*20

r^2 = 1540/20 π = 24.510

r = 4.95 cm.
