The variable m should equal -5
Answer:
A)
Step-by-step explanation:
the solution of a squared equation is
x = (-b ± sqrt(b² - 4ac)) / (2a)
in our case
a = 1
b = 8
c = 22
x = (-8 ± sqrt(64 - 88))/2 = (-8 ± sqrt(-24))/2 =
= (-8 ± sqrt(4×-6))/2 = (-8 ± 2×sqrt(-6))/2 =
= -4 ± sqrt(-6) = -4 ± i×sqrt(6)
Step-by-step explanation:
Pythagoras' theorem for the smallest one :
= 52
Pythagoras' theorem for the middle one :
= 
+ 
Pythagoras' theorem for the biggest one :
Using the formula before (for 
) it becomes :
16 + 8a = 52 + 36
16+8a = 88
8a = 88-16
8a = 72
a = 9
Verifying :
= 117
The biggest one :
True
answer:
2,558
step-by-step explanation:
the formula for the volume of a cone is v=πr²h/3
with that let us 'fill in' the formula-
v=π*9.6²*26.5/3
v=2,557.51
then since you've asked us to round the answer to the nearest whole number that would be 2,558
good luck :)
i hope this helps
brainliest would be highly appreciated
have a nice day!
