Answer:
Given Exponential Function is :

We have check which graph represent given Exponential Function,
let, 
Put x = 0, we get

y = 5 × 1 - 1 = 4
One of the passing through point = ( 0 , 4 )
Now, Put y = 0, we get






x = -1.465
Another passing through point is ( -1.465 , 0 )
So, Clearly No Given Option in attached is correct.
Correct Graph is attached.
Answer:
wheres the question. that's just a topic
Step-by-step explanation:
We know that if (h,k) is the center of any circle and whose radius is = r then its equation is :

Given, the equation of circle

By comparing, we will get,
h = -2
k = 3
So, center of the circle is ( -2,3)

Answer:
diameter = 2.5 feet
Step-by-step explanation:
Circumference of a circle is given as C = πd
Circumference of the tree trunk = 7.85 ft
π = 3.14
Diameter of the tree trunk = d
Thus:
7.85 = 3.14*d
Divide both sides by 3.14
7.85/3.14 = 3.14*d/3.14
2.5 = d
d = 2.5 ft
