Answer:

2V130 , 8V2

Step-by-step explanation:

If these are cahetus

x^2=14^2+18^2=196+324=520

x=V520=2V130

if 18 is not a cathetus  then

18^2=x^2+14^2

x^2=18^2-14^2

x^2=324-196=128

x=V128

x=8V2

What ones are functions and which are not pls help
Fantom [35]
Functions: the chart with number values, the dot graph, and the middle graph on the right

Not functions: the top graph on the left with the vertical line, the graph with the circle, and the bottom right graph

Any graph that doesn’t pass the vertical line test is not a function. You can do this by starting at the top of the graph and drawing a line straight down through what you are testing. If you pass through the line or circle more than once it is not a function.
If you look at the number values if the x value repeats more than once it is not a function.

Please help me with this explain!!!!!

Given:
Cylinder: radius = 8 yd; height = 4 yd
Surface Area = 2 π r h + 2 π r²
SA = 2 * 3.14 * 8 yd * 4yd + 2 * 3.14 * (8yd)²
SA = 200.96 yd² + 401.92 yd²
SA = 602.88 yd²
Volume = π r² h
V = 3.14 * (8yd)² * 4yd
V = 803.84 yd³

Dimension is cut in half. radius = 4yds ; height = 2yds
S.A = 2 * 3.14 * 4yd * 2yd + 2 * 3.14 * (4yd)²
S.A = 50.24 yd² + 100.48 yd²
SA = 150.72 yd²
V = 3.14 * (4yd)² * 2yd
V = 100.48 yd³

SA =
602.88 yd² - 150.72yd² = 452.16 yd²
V =
803.84 yd³ - 100.48 yd³ = 703.36 yd³
