150m - 100m + 47.750 = 50.500- 200m​
coldgirl [10]

Answer:

m=11÷600

Step-by-step explanation:

150m-100m+47.750=50.5000-200m

collect the like terms

-50m+47.75=50.5-200m

move variable to the left side and change its sign

-50m+200m+47.75=50.5

Move constant to the right side and change its sign

50m+200m=50.5-47.75

collect the like terms(again)

150m=50.5-47.75

subtract the numbers

150m=2.75

divied both sides of the equation by 150

m=11÷600

solution

m=11÷600

alternative form

m=0.0183

Please help, it's urgent!
Aneli [31]

For this case we have to, by defining properties of powers and roots the following is fulfilled:

\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}

We must rewrite the following expression:

\sqrt [3] {8 ^ {\frac {1} {4} x}}

Applying the property listed we have:

\sqrt [3] {8 ^ {\frac {1} {4} x}} = 8 ^ {\frac{\frac {1} {4} x} {3} }= 8 ^ {\frac {1} {4 * 3} x} = 8 ^ {\frac {1} {12} x}

Using the property again we have to:

8 ^ {\frac {1} {12} x} = \sqrt [12] {8 ^ x}

Thus, the correct option is option C

Answer:

Option C

Polygon ABCD is dilated by a scale factor of 2 with the center of dilation at the origin to create polygon A′B′C′D′. If the endp
liq [111]

Answer:

A'B' = 34 units

Step-by-step explanation:

Since the dilatation is centred at the origin , then multiply the coordinates by 2

A' = (2(0), 2(- 7) = (0, - 14 )

B' = (2(8), 2(8) = (16, 16)

Calculate the length using the distance formula

d = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2    }

with (x₁, y₁ ) = A'(0, - 14) and (x₂, y₂ ) = B'(16, 16)

d = \sqrt{(16-0)^2+(16+14)^2}

   = \sqrt{16^2+30^2}

   = \sqrt{256+900}

   = \sqrt{1156}

   = 34
