e is a special number, so you would need to use a calculator to solve this.

a) replace t in the equation with 5 ( 2005 - 2000 = 5 years)

A = 16.6e^0.0457*5 = 20.86 million Round to nearest tenth = 20.9 million.

b) replace A with 23.3 and solve for t:

23.3 = 16.6e^0.0457*t

Divide both sides by 16.6:

1.4036 = e^0.0457t

Take the natural logarithm of both sides:

0.0457t = LN(1.4036)

Divide both sides by 0.457:

t = LN(1.4036)/0.0457

t = 7.419 years, rounded to nearest tenth = 7.4 years.

Gimme the radius circumference and area<br> plsss i beg
Gala2k [10]

Answer:

radius = 5.75 units

circumference = 36.11 units

Area = 103.81625 square units

Step-by-step explanation:

Radius = 11.5 / 2 = 5.75

Circumference = 11.5 x 3.14 = 36.11

Area = 5.75 x 5.75 x 3.14 =

33.0625 x 3.14 =

103.81625 units square

This is all if pi = 3.14

Hope that helps!

Translate the sentence into an equation using n to represent the unknown number. Then solve the equation for n.
Ulleksa [173]
Let the unknown number be "n",

This number is sutracted from 46. So, 46 less n.
That is (46 - n).
The result to this is -21.
∴The equation would be;

46 - n = -21.
Now solve for n.
46-n=-21
46 + 21 =n
∴n=67

6. Write the inequality using interval notation for the graph.
makkiz [27]

Answer:

C

Step-by-step explanation:

C is the correct answer because it represents exactly what the graph shows with the bold lines.

As you can see in the graph, there is no interception between 7 and 12. Therfore, the answer can't be B(because it represents the area between the two numbers).

A isn't the correct answer either because it represents a dot, which is obviously not the case here since there is no dot.

I can't explain why C isn't the right answer, but I hope that explanation that I gave is enough for you to understand ;)

(If you have any questions about the way I solved it, don't hesitate to ask me in the comments, and if you find my answer helpful - consider marking it Brainliest ÷) )
