Basically, r=2t
A(r)=pir^2
sub 2t for r
A(2t)=pi(2t)^2
A(2t)=4pit²
A. A=4pit²
B. t=5
A=4pi5²
A=4pi25
A=100pi
A=314 square units
By analyzing the end behavior of the graphed function, we conclude that the graphed function is an exponential one.
<h3>
Which type of function is f(x)?</h3>
On the graph, we can see that as the independent variable (the one in the horizontal axis) tends to large negative values, the dependent variable (the one in the vertical axis) tends to zero.
And, as the independent variable increases in the positive domain, also does the dependent variable. So we have an increasing function
Finally, we can see that the range (set of the outputs) of the function is the set of values larger than zero.
These 3 are characteristics of exponential functions, so we conclude that the graphed function is an exponential one, thus the correct option is the first one.

#SPJ1
Line y = –x + 4 intersects the line y = 3x + 3., this is the right answer
Perimeter is the sum of all sides in the figure. Here, all six sides are equal in length so it would be:
p = 6 * side
p = 6 * 3.9
p = 23.4 cm
In short, Your Answer would be: 23.4 cm
Hope this helps!
Answer:
a = 5
Step-by-step explanation:
If it's easier for you, you can replace n(a) with y and put a as x.
Now the equation is y = 7x + 4.
It asks you to put in 39 as y.
39 = 7x + 4.
To solve this, the goal is to isolate the variable on one side. The first step I see is to subtract the 4 from both sides.
35 = 7x
Now divide both sides by 7 and we're done!
5 = x
