Answer:
7.5 miles
Step-by-step explanation:
Half of 5 equals 2.5. Bobby already walked 5 miles so you add the 2.5 since he walked another half of that distance. 5 + 2.5 = 7.5
We have to convert it to km/h




Your proportion should look something like this

After cross multiplication, you should end up with this equation

After dividing 4 on both sides, you should get that x=9
Answer:
f^-1 (x)=x^2-4x+1
Step-by-step explanation:
y=sqrt(x+3)+2
x=sqrt(y+3)+2
sqrt(y+3)=x-2
y+3=(x-2)^2
y+3=(x-2)(x-2)
y+3=x^2-2x-2x+4
y+3=x^2-4x+4
y=x^2-4x+4-3
y=x^2-4x+1
Answer:
Height of the tree is 78.11 feet.
Step-by-step explanation:
By applying the tangent rule in the right triangle formed,
Since, tanθ = 
tan(32)° = 
h = 125(tan32°)
h = 125(0.62487)
h = 78.109
≈ 78.11 ft
Height of the tree will be 78.11 feet.
