Answer: x = -3 + √3 or x = -3 - √3
The explicit rule for the sequence in simplified form is y = 30000(2)^n
<h3>How to write the exponential function</h3>
The standard exponential equation is expressed as:
y = ab^n
Given the following parameters
a is the initial values = 30,000
If the amount doubles each year then b = 2
Substitute the parameters
y = 30000(2)^n
Hence the explicit rule for the sequence in simplified form is y = 30000(2)^n

Answer:
The volume is 81 m³.
Step-by-step explanation:
This is the right rectangular prism which dimensions are:
W = 3 m , L = 4.5 m , H = 6 m
The volume of the prism:
V = W * L * H
V = 3 m * 4.5 m * 6 m = 81 m³
Answer:
cos(63)=y/15
tan(27)=y/x
sin(63)=x/15
Step-by-step explanation:
You need to memorize the definitions of all the trig functions. Then these types of problems will be easy for you. OK?
Width = w, length =l
l-4=w
2w+2l=perimeter=72
Substituting l-4 for 2, we get 2(l-4)+2l=72 and 2l-8+2l=72. After that, we get 4l-8=72 and 4l=80, getting l=20. Since l-4=w, w=16
