Answer:
what happened to spinner b
Step-by-step explanation:
Answer: D
Step-by-step explanation:
I substituted in the value of x (2) to see if it gave me the value of y (1) because that’s the point it gave on g(x).
The only equation that worked was D.
1/2*2=1 then 1^2=1
Answer: 6 ways
there are 6 ways to move from one corner of a cube to the diagonally opposite corner in three moves
Step-by-step explanation:
Given that;
-It's restricted to three moves.
-It has to move from one diagonal to its opposite diagonal.
-it can only move through the edges.
Hence, in the first move.
We have three(3) different options that is three different possible moves that can lead us to the final destination.
The second move.
We have two (2) different possible moves each
The last move
We have just one(1) possible move.
To get the total possible ways, we will multiply the possible options for each move.
Move 1 = 3 options
Move 2 = 2 options each
Move 3 = 1 option each
3 × 2 × 1 = 6 ways
Answer:
A: 779 cm²
B: 1837 cm²
Step-by-step explanation:
For both problems, use the formula for surface area of a cylinder:
SA = 2πr² + 2πrh
2πr² is the two bases.
2πrh is the curved surface.
<u>PROBLEM A</u>
"the cylinder is 60 cm long" is h = 60.
If given diameter, you can find "r" by dividing it by 2. d = 2r
Given d = 4, then r = 2.
SA = 2πr² + 2πrh
SA = 2π2² + 2π2(60)
SA = 8π + 240π Add
SA = 248π Exact answer
SA ≈ 779.114978 Answer on calculator
SA ≈ 779 Rounded answer
Remember to include the units.
The surface area is about 779 cm².
<u>PROBLEM B</u>
"80 cm long" h = 80.
"circumference of 22 cm". C = 22. Remember C = 2πr. Find "r".
C = 2πr
22 = 2πr
11 = πr
r ≈ 11/π
SA = 2πr² + 2πrh
SA = 2π(11/π)² + 22(80) Substitute 2πr with the circumference.
SA ≈ 1837.030992 Answer on calculator
SA ≈ 1837 Rounded answer
Remember to include the units.
The surface area is about 1837 cm².
F(x) = (4x^2 - 36x) / (x-9)
0 = 4x * (x-9) / (x-9)
0 = 4x
x=0
hope this helps
