The distance covered by the hiker if he traveled a horizontal distance of 120 ft at and angle of 6° will be given by:
cos θ=adjacent/hypotenuse
let the hypotenuse be h, adjacent =120 ft, θ=6°, thus plugging in the values we shall have:
cos 6=120/h
h=120/cos 6
h=120.661 ft
Answer: 120.661 ft

What is the percent change of $15.60 to $11.70?
Rashid [163]

Answer:

percentage change=25% .

Step-by-step explanation:

Given : $15.60 to $11.70    .

To find:  What is the percent change .

Solution: We have given that   $15.60 to $11.70  .

Change = final value - initial value .

Change   = $15.60 - $11.70  

                   =$3.9

percentage change = \frac{change}{original value}*100

                                =   \frac{3.9}{15.60}*100

                                =   \frac{390}{1560}*100.

On dividing both number by 3

percentage change=\frac{130}{520}*100.

percentage change=\frac{1}{4}*100.

percentage change=25% .

Therefore, percentage change=25% .

Answer:

a² + b² = 68

a3 + b3 = 520

Step-by-step explanation:

Given :

a + b = 10 (1)

ab = 16 (2)

A. Find a² + b²

(a + b)² = a² + 2ab + b² (3)

Substitutite the values of (1) and (2) into (3)

(10)² = a² + 2(16) + b²

100 = a² + 32 + b²

Subtract 32 from both sides

100 - 32 = a² + b²

a² + b² = 68

B. a^3 + b^3

(a + b)^3 = a^3 + b^3 + 3ab(a + b)

(10)^3 = a^3 + b^3 + 3*16(10)

1000 = a^3 + b^3 + 480

a^3 + b^3 = 1000 - 480

a3 + b3 = 520
