Answer:

Solution:-

(106)³ - (94)³

(100+6)³ - (90 + 4)³

(100 + 6)³ = (100)³ + 3 × (100)² × 6 + 3 × 100 × (6²) + (6)³ [By using the identity (x+y)³ = x³+3x²y+3xy²+y³]

= 1191016

(90 + 4)³ = (90)³ + 3 × (90)² × 4 + 3 × 90 × (4)² + (4)³ [By using the same identity] = 830584

1191016 - 830584

= 360432 Answer.

Answer: A. 241 feet

Step-by-step explanation:

The figure shows two rectangular triangles.

These triangles are similar since they have two identical angles:

the first angle is 90 degrees;

the second angle is equal because the law of reflection states that the angle of incidence is equal to the angle of reflection.

The law of reflection states that the angle of incidence is equal to the angle of REFLECTION.

Let's make the proportion:

$\dfrac{4}{273} =\dfrac{5}{x} \\\\x=\dfrac{273 \cdot 5}{4} =341.25 \: (feet)\\$

It takes a minimum of 100 feet for a parachute to open and safely land without injury, so:

341.25 - 100 = 241.25 (feet)

241.25 ≈ 241 (feet)
