Spain = 140
Italy = 40
France = 60
U.S.A = 120
total = 18,000,000

Spain : 140/360 = 39%.....0.39(18,000,000) = 7,020,000
Italy : 40/360 = 11%....0.11(18,000,000) = 1,980,000
France : 60/360 = 17%....0.17(18,000,000) = 3,060,000
U.S.A : 120/360 = 33%...0.33(18,000,000) = 5,940,000

Which is the graph of f(x) = StartRoot x EndRoot?
Bingel [31]

The equation of the graph of f(x) = \sqrt x is (d) on a coordinate plane, an absolute value graph starts at (0, 0) and goes up through (4, 2).

The equation of the graph is represented as:

  • f(x) = \sqrt x

See attachment for the graph of f(x) = \sqrt x

From the attached graph, the curve passes through points (0,0) and (4,2).

Hence, the equation of the graph of f(x) = \sqrt x is (d)

May anyone help me i have no idea
shtirl [24]

Answer:

No.  GCF = 2

2(x^2 - 5x + 10)

2(x^2 - 5x + 10)       (\dfrac{-5}{2})^2=(-2.5)^2 =6.25

2[x^2 - 5x+6.25-6.25 + 10]

2[(x^2 - 5x+6.25)-6.25 + 10]

2[(x - 2.5)^2-6.25+ 10]

2[(x - 2.5)^2+3.75]

2(x - 2.5)^2+7.5
