Answers

Answer 1
Answer:

Answer:

x and x+4

Step-by-step explanation:

since area is product of length and breadth for a rectangle . if we factorise the area given , take x as common the other expression comes out to be x+4 . hence dimensions are x and x+4

^the answer above is wrong. The answer is 9.

10x = 90
Divide both sides by 10, and you get, x = 9.

To check:
Plug in 9 for x in the diagram above.
6(9) + 4(9)
54 + 36
=90, which is given as a clue on the left side.

A hyperbola is represented using the equation (x-1)^2/4-(y+2)^2/16=1. What are the slopes of the asymptotes?

Answers

Answer:

the slope of the asymptotes are: 2 and -2

Step-by-step explanation:

As we know the hyperbola equation is:

((x-h)^2)/(b^2)-((y-k)^2)/(a^2)=1

Given the hyperbola equation:

((x-1)^(2) )/(4) - ((y+2)^(2) )/(16) = 1

We have  a=2 and b=4, h=1 and k=-2

and the asymptote equation of a translate hyperbola with equation is:

y=\pm(b)/(a)(x-h)+k

We substitute this values to get:

y=\pm(4)/(2)(x-1) -2  

<=> y = 2x -4 or y = -2x

so the slope of the asymptotes are: 2 and -2

Answer:

m=2

b=-4
