Most of the information's required for solving the question is already given in the question.
Height of the building that casts a shadow of 20 m = 32 m
Then
Height of the man that casts a shadow of 1.2 m = (32/20) * 1.2 meter
= 3.2 * 1.2 meter
= 3.84 meter
So the actual height of the person casting a shadow of 1.2 meter is 3.84 meters. I hope that the procedure used for solving the problem is easy enough for you to understand. You can definitely use this method in future for solving problems of similar type without requiring any additional help from outside.
Given equation is y=2x which change to y=2x-3 . Now we need to check following which transformations, the equation y=2x changes to y=2x-3 .
Because of -3 with the given function y=2x, the graph shifts to 3 units down. So the transformation is 3 units downwards. If -3 is inside the function that is y=2(x-3), in that case the equation shifts to 3 units right. But since here we have -3 with the function not inside the function, so the equation shifts to 3 units downwards and that's the required transformation .
Answer:
20
Step-by-step explanation:
We are told in the question that
John scored a mean of 19 points in his first 3 basketball games
His total points for his first 3 games = Number of games × Mean of those games
= 3 × 19
His total points for his first 3 games = 57 points
We aslo told that in his fourth game, he scores 23 points.
His average score for all four basketball games is calculated as:
(57 points + 23 points) ÷ 4 games
= 80 points ÷ 4 games
= 20
His Average for the four games = 20
