Answer:
the equation for the line would be x= 4
Step-by-step explanation:
vertical lines means that only the x axis will be crossed by the line
this means that if you have a point of a vertical line, you can take the x value in it to determine the equation
Answer:
3 30303/125000
Step-by-step explanation:
Divide the expression for the area by the length 6x ( width = area/length)
this gives the width :-
= 2x^2 + 3x - 4 Answer
Answer:
y=9 when x=24
Step-by-step explanation:
We know that
<span>the sphere is divided into two hemispheres
</span><span>the two hemispheres are equals
</span><span>
if </span><span>Tran computes the amount of paint needed to cover the sphere
</span><span>therefore
</span>Tran computes the amount of paint needed to cover <span>both hemispheres.
</span>
the answer is
Tran found the minimum amount of paint needed to cover both hemispheres.
[surface area of sphere]=4*pi*r²
[surface area of each hemisphere]=2*pi*r²
circumference=18.84 cm------> 2*pi*r------> r=18.84/(2*pi)------> 3cm
[surface area of each hemisphere]=2*pi*3²---------> 56.52 cm²
surface area of sphere=2*56.52=113.04 cm²
