Answer:
h(3b)=12b+4
another answer
h(3b)=4(3b+1)
Step-by-step explanation:
h(x)=4x+4
h(3b)=4(3b)+4
h(3b)=12b+4
if need to simplify..then:
h(3b)=4(3b+1)
Step-by-step explanation:
in isoscles triangles two angles and lengths are equal .
two sides equal 3.5
so both of the angles are 55°
the sum of the angles in a triangle is 180°, so
x = 180° - 55° - 55°
x = 70° (Ans)
Answer:
A=πr^2
Step-by-step explanation:
A=Area
r=Radius
Answer:
88 centimeters is the diameter of the cilinder
Step-by-step explanation:
The pressure on both ends of the lift must be the same. Assuming the piston is cilindrical, its area will be A=π*r² where r is half the diameter
Since pressure P=F/A And P1=P2
F1=2000kg.g
A1=π*r²
F2=25kg.g
A2=π*0.05²
2000/(π*r²)=25/(π*0.05²)
and we solve for A1
r²=2000*0.05²/25

r=
20*0.05/5=0.44m or 44cm
This is the radius, meaning that the diameter will be twice this number
