Answer:

R(7a, 0 )

Step-by-step explanation:

R is on the vertical line RQ so will have the same x- coordinate as Q

R is on the horizontal line OR so will have the same y- coordinate as O

Thus coordinates of R = (7a, 0 )

In a dog show, there will be a gold and silver medal awarded.There are 6 finalists. In how many ways can the 2 medals be awarded

Mandarinka [93]

Answer:

Step-by-step explanation:

Given: There are six finalists and two medals. That is it asks for the possibilities of 6 finalists taking two at a time. Say, for example the first and third finalist or the second and the sixth finalist and so on. The number of possibilities is given by $^nP_r$

$^nP_r = \frac{n!}{(n - r)!}$

So the number of possibilities of 6 finalists taken two at a time is $^6P_2$

$\implies \frac{6!}{(6 - 2)!} = \frac{6!}{4!} \hspace{15mm} [n! = n \times (n-1) \times (n - 2) \times . . . 2 \times 1]$

$\implies \frac{6 \times 5 \times 4 \times \times 3 \times 2 \times 1}{4 \times 3 \times 2 \times 1} = 6 \times 5 = 30$

Suppose xy=−2 and dy/dt=−4. Find dx/dt when x=−1.

Nikitich [7]

Answer:

-2

Step-by-step explanation:

Dividing the given equation by x, we find y to be ...

y = -2/x

Then ...

dy/dx = 2/x^2

and ...

dy/dt = (2/x^2)dx/dt

dx/dt = (x^2/2)dy/dt

When dy/dt = -4 and x=-1, this is ...

dx/dt = (-1)^2/2(-4) = (1/2)(-4)

dx/dt = -2
