A
Step-by-step explanation:
To translate a graph right you -3 from x. To translate a graph up you +4.
Answer:
5' 6" = 66 inches
6 feet = 72 inches
shadow to actual height ratio = 72 / 66 = 1.0909...
If the tree casts a 20 foot shadow then its height equals
20 / 1.09090909 = 18.33 feet = 18 feet 4 inches
Step-by-step explanation:
Answer: F
Step-by-step explanation:
1+2+...+n = n*(n+1)/2 for all natural numbers n.
Left-hand-side = (5+1)+(5+2)+...+(5+10)=5*10+10*(10+1)/2=50+55=105
Right-hand-side = (4)+(4+1)+...+(4+9)=4*10+9*(9+1)/2=40+45=85
105≠85
The equation is false
Answer:
see explanation
Step-by-step explanation:
The statements tells us that w is inversely proportional to v and the equation relating them is
v = 
← k is the constant of proportion
To find k use the condition v = 9, w = 5, that is
9 = 
( multiply both sides by 5 )
45 = k
v = 
← equation of proportion
When w = 4 , then
v = 
= 11.25
