The exponential functions change is represented by decay and the percentage rate of decrease is 1.00619%.
Step-by-step explanation:
Step 1:
To determine if the function represents growth or decay, we substitute values to x.
If the values increase with an increase of x, it represents growth.
If the values decrease with an increase of x, it represents decay.
Step 2:
If 
If 
So as x increases the value of y decreases, so it represents decay.
Step 3:
The percentage rate of change is determined by dividing the difference of two consecutive values by the first value.
The percentage rate of change 
Substituting the values, we get
The percentage rate of change 
.
As the values of y decrease with an increase in x, it is the percent decrease per unit.

Step-by-step explanation:
Answer:
49+112=161
Step-by-step explanation:
first find the base b^2 which is 7^2 which is 49, then find one of the side then * 4 which is 7*8/2*4=112, add them together gets 161. Done!
Answer:
x = 9
Step-by-step explanation:
What we have here is a bisected angle. What this means is that an angle is being cut in half to create multiple angles. In this case angle E has been bisected. Since that is the case, angles 1 and 2 are equivalent to each other. Now that we know this we can solve for x.
Equation:
x + 8 = 2x - 1
8 = x - 1
9 = x
Answer:
80°
Step-by-step explanation:
In the ratio 
, the largest value corresponds to the largest angle. The sum of the ratio is 
.
The sum of angles in a triangle is 180°. Then 
is given by
