Answer:
<em>y = </em>
<em> x + 1 </em>
Step-by-step explanation:
If AB ⊥ CD , then ( 
) ( 
) = - 1
y = - 
x + 3
y - ( - 4) = ( x - 7) ⇔ <em>y = </em><em> x + 1 </em>
Answer:
The correct answer is second option option
9¹/⁸ ˣ
Step-by-step explanation:
<u>Points to remember</u>
<u>Identities</u>
ᵃ√x = = x¹/ᵃ
√x = x¹/²
(xᵃ)ᵇ = xᵃᵇ
<u>To find the correct option</u>
It s given that,
(⁴√9)¹/² ˣ
By using the above identities we can write,
(⁴√9)¹/²ˣ = (9¹/⁴)¹/²ˣ [ since ⁴√9 = 9¹/⁴]
= 9⁽¹/⁴ * ¹/²⁾ ˣ
= 9¹/⁸ ˣ
Therefore the correct answer is second option option
9¹/⁸ ˣ
If 5 in and 8 in are legs:
hypotenuse = √(5²+8²) = √89 ≈ 9.4 in.
If 5 in is the leg and 8 in is the hypotenuse:
other leg = √(8²-5²) = √39 ≈ 6.2 in.
<span>The difference between the two possible lengths of the third side =
9.4 - 6.2 = 3.2 in.</span>
