Hope this helps
Answer:
Use this formula for these kinda things.
Step-by-step explanation:
Remember The z is the hypathonous, it means the biggest side.
where Z is going to be C
put this all together
put it into calculator, means 373=
therfore take the square root, it will be
which it will be 19.31
Answer:
5.625
as a mixed number = 5 and 5/8
Step-by-step explanation:
I'll go over part A.
What's happening is that we are plugging some unknown number x into the function, and getting -1 as the result. The function rule is 3*x-7 which translates to "multiply the input number by 3, then subtract off 7"
Notice how multiplication comes first and then we subtract. This is following the order of operations PEMDAS (some books may call it BEDMAS depending on your region). The M for multiplication comes before the S for subtraction.
To isolate x, we follow the order of operations in reverse. We undo the "subtract off 7" then we undo the "multiply by 3"
So this is how it all works out
f(x) = 3x-7
-1 = 3x-7 .... replace f(x) with -1
3x-7 = -1
3x-7+7 = -1+7 ... add 7 to both sides to undo the "-7"
3x = 6
3x/3 = 6/3 ... divide both sides by 3 to undo the "multiplication"
x = 2
Therefore, if the input is 2, then output is -1
------------------------------------------------------------
Let's plug x = 2 into the function and see what happens
f(x) = 3x-7
f(2) = 3*2-7 .... replace x with 2
f(2) = 6-7 .... multiply
f(2) = -1 .... subtract
The input x = 2 leads to the output -1
So this confirms that x = 2 is the proper answer for part A
Total surface area:
D.)2940pie ft2 (9236.28)
lateral surface area:
3581.4
1st -you times the answer choices by pie
2nd- you follow the cylinder lateral surface area formula= L= circumference times the height
circumference is : pie time radius squared
3rd- you follow the the total surface area formula= S=2B+ L
B=pie times radius squared
L=lateral surface area
4th- the answer you got for total surface area.
find the answer choice that has your answer.
