Ok, well a square is basically two triangles, right? the 45 degree right triangle. if you consider the rules for a 45 degree right triangle, you get: x, x, 2sqrt(x)
plugging in 8, you get the diagonal to be 2sqrt(8) or 4sqrt(2)
Answer:
= 21.6216% decrease
Step-by-step explanation:
Calculate percentage change
from V1 = 29.6 to V2 = 23.2
(V2−V1)|V1|×100
=(23.2−29.6)|29.6|×100
=−6.429.6×100
=−0.216216×100
=−21.6216%change
=21.6216%decrease
Answer:
C
Step-by-step explanation:
SA=4*pi*r^2
SA=4*pi*2^2
SA=4*pi*4
SA=16*pi m^2
SA≈50.2654824574
SA≈50.3 m^2
Which is C

Answer:
y = - 2x + 18
Step-by-step explanation:
Step 1:
y = mx + b Slope Intercept Form
Step 2:
y = - 2x + b Input Slope Value
Step 3:
0 = - 2 ( 9 ) + b Input x and y values
Step 4:
0 = - 18 + b Multiply
Step 5:
b = 18 Add 18 on both sides
Answer:
y = - 2x + 18
Hope This Helps :)
