The quantity a varies directly with b and c and inversely with dThe quantity d is tripledWhich of the following must be true for

EastWind [94]

Answer:

We have the next relation:

A = (b*d)/c

because we have direct variation with b and d, but inversely variation with c.

Now, if we have 3d instead of d, we have:

A' = (b*(3d))/c

now, we want A' = A. If b,c, and d are the same in both equations, we have that:

3bd/c = b*d/c

this will only be true if b or/and d are equal to 0.

If d remains unchanged, and we can play with the other two variables we have:

3b'd/c' = bd/c

3b'/c' = b/c

from this we can took that: if c' = c, then b' = b/3, and if b = b', then c' = 3c.

Of course, there are other infinitely large possible combinations that are also a solution for this problem where neither b' = b or c' = c

Answer:

Step-by-step explanation:

1. a). Hypotenuse² = (Leg 1)² + (Leg 2)²

h² = 10² + 24²

h = √676

h = 26

(b). Hypotenuse² = (Leg 1)² + (Leg 2)²

(25)² = (15)² + (leg 2)²

Leg 2 = √(625 - 225)

= √400

= 20

(c). Hypotenuse² = (Leg 1)² + (Leg 2)²

h² = 4² + 6²

h = √(16 + 36)

h = √52

h = 2√13

(d). Hypotenuse² = (Leg 1)² + (Leg 2)²

(14)² = (Leg 1)² + 7²

Leg 1 = √(196 - 49)

= √147

= 7√3

2). Hypotenuse² = (Leg 1)² + (Leg 2)²

Leg 1 = leg 2 = 7 units [Since, triangle is an isosceles triangle]

h² = 7² + 7²

h = √98

h = 7√2

Option (1) is the correct option.

3). Hypotenuse² = (Leg 1)² + (Leg 2)²

(26)² = (Leg 1)² + (10)²

Leg 1 = √(676 - 100) = 24

Area of a right triangle = $\frac{1}{2}(\text{Leg 1})(\text{Leg 2})$

= $\frac{1}{2}(24)(10)$

= 120 square units

Option (3) is the correct option.
