Answer:
Distance: 25 miles
Step-by-step explanation:
we have distances between cities as follows:
From Portland to Tacoma: 120 miles
from Portland to Seattle: 145 miles
120+x=145 ⇒ x = 145 - 120 = 25 miles
from Tacoma to Seattle : 25 miles (according graph)
Answer: Yes.
Step-by-step explanation:
It forms an obtuse triangle.
180 degrees of the triage

We are decreasing so, we first of find 68% of 225
= 68 / 100 * 225 = 17/ 25 * 225 That is using 4 into 68 and 100
17/5 * 45 Using 5 into 25 and 225.
17 * 9 = 153.
Since we are decreasing then we are going to subtract this result from 225.
If we were increasing we would have added.
= 225 - 153 = 72.
That's our answer. Cheeers.
The expression 1.5 x 1.09^t models the housing costs, in thousands of dollars, for summer term t years since Chinedu applied to his college.
Now In general we have the following rule for exponential functions:
Here we have two cases for b:
Case 1: if b<1 , we call it as exponential decay.
Case 2: if b>1 , we call it as exponential growth.
Now let us compare our equation with this general form,
1.5 x 1.09^t
Here b is 1.09, which is greater than 1.
So here we can say that the housing cost is increasing exponentially by a factor or 1.09.
