It is just the multiplication of vectors. We'll multiply corresponding pairs together. The general formula for the pairs of (

;

) and (

;

) is

= (-6)*(-3)+4*6=18+24=42
Y=-3/4x+2, thats the slope intercept form
F (x+h)-f (x)/h

Answer:
Find the post height first. 3/5= 0.8, so the shadow is 80% of the height of the object. Multiply 80% by 27 to get 21.6
The tree is 21.6 meters tall.
Step-by-step explanation:
We are asked in the problem to determine the simplest form of the number 45/60. The greatest common factor of the two numbers is 15. Hence, we divide each number by 15, that is 45 over 15 is equal to 3 and 60 over 15 is equal to 4. Hence the answer is 3/4.
