What is the following product? 3v2(5v6-7v3)

Mathematics

steposvetlana [31]3 years ago

Answer:

3v^2\left(5v^6-7v^3\right)=15v^8-21v^5

Step-by-step explanation:

Given the expression

3v^2\left(5v^6-7v^3\right)

Apply the distributive law

a\left(b-c\right)=ab-ac

a=3v^2,\:b=5v^6,\:c=7v^3

=3v^2\cdot \:5v^6-3v^2\cdot \:7v^3

=3\cdot \:5v^6v^2-3\cdot \:7v^3v^2

=15v^8-21v^5

Thus, we conclude that

3v^2\left(5v^6-7v^3\right)=15v^8-21v^5

Find the vertical asymptotes. 2x2 + 7x + 6 y = 3x2 + 10x - 8 * = [ [?], x=​
Llana [10]

Answer:

-\frac{77}{24}

Step-by-step explanation:

1. rewrite the equation in standard form: 4\cdot \frac{3}{2}\left(y-\left(-\frac{41}{24}\right)\right)=\left(x-\left(-\frac{3}{2}\right)\right)^2

2. find (h,k), the vertex. the vertex is \left(h,\:k\right)=\left(-\frac{3}{2},\:-\frac{41}{24}\right)

3. find the 'focal length' of the parabola - the focal length is the distance between the vertex and the focus. from the vertex we can see that the focal length, p, = 3/2

4. Parabola is symmetric around the y-axis and so the asymptote is a line parallel to the x-axis, a  distance p from the \left(-\frac{3}{2},\:-\frac{41}{24}\right) y coordinate which is at  -\frac{41}{24}\right). Set up the equation:

y=-\frac{41}{24}-p

5. substitute and solve:

y=-\frac{41}{24}-\frac{3}{2}

y = -\frac{77}{24}

hope this helps, ask me questions if you still don't understand.
