The surface area is
A1=7.5*1.5*2=22.5 ft2 top and bottom view
A2=3*1.5*2=9 ft2 laterals view
A3=(7.5*1.5+2.5*1.5)*2=30 ft2 front and rear view
At=22.5+9+30=61.5 ft2
the answer is 61.5 ft2
Multiplying 5 to the first fraction we get 15/25+1/25=16/25
You use explicit funtion to find a particular number in the list without needing to write all the list down.
For example, the first range of number has a constant difference of 5. Its explicit funtion would be: x(n)=3+(n-1)*5 (with x is the number you need to find, n is the number's position in the range)
Basically, a explicit funtion in that problem has the form:
x(n)=f+(n-1)*d
with:
x= the number needed to find
n= the number's position
f = the first number in the range
d = the distance
Good luck!
For graphing, the desmos graphing calculator is a big help :))
Step-by-step explanation:
5.
g(x)=-2x+1
let y=2x+1
Interchanging role of x & y
x=2y+1
y=½x-½
g-¹(x)=½(x-1)
not
equal to f(x)=-x+1
<u>Given function are not function of each other</u> .
6.
g(x)=-x
let
y=-x
Interchanging role of x & y
x=-y
y=-x
g-¹(x)=-x
not
equal to f(x)=3+⅓x
<u>Given function are not function of each other .</u>
