Answer:
Grayson has to walk 1.7 miles across the field.
Step-by-step explanation:
We have drawn the diagram for your reference.
Given:
Grayson usually walks 1.5 miles west on the side walks
According to Diagram we can say;
CA = 1.5 miles
Also Given:
Grayson also walks 0.8 miles north on the sidewalks
So According to Diagram we can say;
BA =0.8 miles
Now we need to find number of miles Grayson have to walk across the field.
According to diagram we can say;
We have to find CA.
Assuming the diagram to be right angled triangle.
We can find CA using Pythagoras theorem.
Substituting the given values we get;
Taking square root on both side we get;
Hence Grayson has to walk 1.7 miles across the field.
The answer is 99.7 percent of chimpanzees
Wouldn't it be 2 since it goes into all them equally.
Answer:
a. U(a) = 20000·0.9^a
b. about -$957 dollars per year
c. 13 years
Step-by-step explanation:
a) The age values are sequential, but the differences between "v" values are not constant. We suspect an exponential function. When we examine the ratios of adjacent table values, we find they are all 0.9, so the exponential function will be ...
U = (initial value)·(0.9^(age))
U(a) = 20000·0.9^a
__
b) The average rate of change for the one year between age 7 and age 8 will be U(8) -U(7). A calculator evaluates that difference as -$956.59, about -$957.
__
c) The car value drops by almost half in 6 years, so will drop by almost half of that in another 6 years. The car's age will be 12 or 13 years. A graph shows the age to be just over 13 years when the value is predicted to be $5000.
_____
A graphing calculator was used to evaluate the function and find the time associated with the given value. (See attached.) This is the "work" that was done to answer the questions.
The time to decrease to 1/4 of the original value can be found by solving ...
5000 = 25000·0.9^a
The solution is ...
a = log(.25)/log(0.9) ≈ 13.158 . . . . as found on the graph
