Answer:
The tree is approximately 22.707 meters tall.
Step-by-step explanation:
The geometric diagram of the problem is included below as attachment. The height of the tree is found by means of trigonometric functions:
Where:
- Elevation angle, measured in sexagesimal degrees.
- Height of the tree, measured in meters.
- Length of the tree shadow, measured in meters.
The height of the tree is cleared in the equation:
If and , the height is:
The tree is approximately 22.707 meters tall.
This is an exponential decay function of the form:
y=ab^x, In this case:
y=15000(0.8^t) so for t=3
y=15000(0.8^3)
y=$7680

Answer:
All real numbers
Step-by-step explanation:
Here, we want to get the domain
The domain refers to the possible x values of the function
As we can see, the plot extends thoroughout the entirety of the graph
This extends from positive infinity to negative infinity
This means that the domain is all real
numbers
Let us assume the common ratio to be = x
then
4x + 13x = 85
17x = 85
x = 85/17
= 5
Then
The ratio will be = 4 * 5:13 * 5
= 20:65
So the ration in which the number 85 can be separated is 20:65. i hope the procedure is clear enough for you to understand. You can always use this method for solving similar problems without taking any help from outside. Only be careful while calculating.
