Answer:
314 m²
Step-by-step explanation:
the surface area of a sphere (As) = 4×pi×r²
our radius r (half the diameter) here is 5m.
=>
As = 4×pi×5² = 4×3.14×25 = 100×3.14 = 314 m²
To answer this... you need to mirror the forgive already shown. Then show the mirror of that one.
Answer:
12 more
Step-by-step explanation:
y-5= 6+ (x+1)
5+6+1=12
Answer:
its a bit blurry i cant see
Step-by-step explanation:
Y + 4x < 8
y < -4x + 8
2 points that satisfy this are (0,8) and (2,0)....and those happen to be ur x and y intercepts (where the line crosses the x and y axis)
graph...so go ahead and plot ur x and y intercepts (0,8) and (2,0).....ur slope is - 4.....so start at ur y int (0,8) and go down 4 spaces, and to the right 1...plot that point, then go down 4 spaces and to the right 1, then plot that point...keep doing this and u will have ur line...u should have crossed the x axis at (0,2)......ur line will be a dashed line since the problem has no equal sign.... the shading will go below the line because it is less then.
y - 3 > = 1/2x
y > = 1/2x + 3
2 points that satisfy this are : (0,3) and (-6,0)...ur x and y intercepts
graph : plot ur intercepts (0,3) and (-6,0)....u have a slope of 1/2...so start at ur x intercept (-6,0) and go up 1 space, and to the right 2 spaces, plot that point...then go up 1 and to the right 2, plot that point...keep doing this and u will cross the y axis at (0,3)....this line will be a solid line....the shading will go above the line.
