Yes, because if you divide 4 and 3 by 2, you get 2 and 1.5
Answer:
f(3) = 6
Step-by-step explanation:
If f(1)=10, then f(1+1)=f(1)-2
f (2) = 10 - 2 = 8
Therefore f(3) = f(2) - 2 = 8 - 2 = 6
38 feet
In the first example the tree was 30 feet but the shadow was 10 feet taller due to the angle of the sun. Assume a 38 foot tree if right there with the same angle of the sun on it, then the shadow will also be 10 feet taller , 48 feet.
Answer:
a. 18 ft
b 12 ft
c 44 inches
Step-by-step explanation:
We can use proportions to solve part a. Put the inches on the diagram on top and the feet in real life on the bottom
4 inches 24 inches
---------------- = --------------
3 ft x ft
Using cross products
4x = 3 *24
Divide each side by 4
4x/4 = 3* 24/4
x = 3 * 6
x = 18 ft
We can use proportions to solve part b. Put the inches on the diagram on top and the feet in real life on the bottom
b) 4 inches 16 inches
---------------- = --------------
3 ft x ft
Using cross products
4x = 3 *16
Divide each side by 4
4x/4 = 3* 16/4
x = 3 * 4
x = 12 ft
We can use proportions to solve part c. Put the inches on the diagram on top and the feet in real life on the bottom
b) 4 inches y inches
---------------- = --------------
3 ft 33 ft
Using cross products
4*33 = 3 *y
Divide each side by 3
4*33/3 = 3* y/3
4*11 =y
44 =y
44 inches =y
