Answer:
down
Step-by-step explanation:
Subtracting 1 from the y-coordinate moves a point down 1 unit. You know this because you know that the y-coordinate tells you the number of units the point is above the x-axis.
Every point on the graph of f(x) has coordinates (x, f(x)). If you subtract 1 from the y-coordinate, you have (x, f(x) -1) = (x, g(x)). The graph of this is a graph of f(x) that is 1 unit down from its original position.
Answer:
The height is 20 meters
Step-by-step explanation:
First set up the equation (Area)80=bh/2 then set up another equation, (height) h=4+2b (base). After this you can substitute h in the equation to end up with 80=(b(2b+4))/2 simplify it to get 80=b^2+2b then solve. The base is 8 meters, plug into the formula that we made before and you find the height is 20 meters.
We have the following diagram
First, we find the distance from Corey to the tree (x). We use the trigonometric tangent identity:
And solve for x:
So, x = 32.32 ft
Now Corey moves back to watch the very same tree at an elevation angle of 41°. The tree has the same height, we find y:
This is y = 92.03 ft
We can know the distance Corey step back by subtracting both distances:
Answer: 59.71 ft
Answer:
7.3%
Step-by-step explanation:
First you have to find out what 38 out of 41 is as a percentage
This is 92.68%
so now we have to do
100.00 - 92.68 this is 7.32
But you said round to the nearest tenth so it would actually be rounded down to 7.3%
