Answer:
y = -
Step-by-step explanation:
Given y varies inversely with x then the equation relating them is
y = ← k is the constant of variation
To find k use the condition y = 7 when x = - 4, then
7 = ( multiply both sides by - 4 )
- 28 = k
y = ← equation of variation
When x = 5 , then
y = = -
Answer:
Hector's kite is 61.84 feet from the ground.
Step-by-step explanation:
The angle of elevation of the kite is 42°15’30” when converted to decimals, it is ≅
Let the height of the kite to the horizontal of angle of elevation be represented as x. Applying the trigonometric function to the sketch of Hector's kite,
Sin θ =
Sin =
⇒ x = 86 x Sin
= 86 x 0.6725
= 57.835
x ≅ 57.84 feet
The height of Hector's kite from the ground = x + 4
= 57.84 + 4
= 61.84 feet
