The distance between the points:
d =  \sqrt{( x_{2} - x_{1} ) ^{2} +(y _{2}-y _{1}) ^{2}   }  \\ d(CD) =  \sqrt{(7-1) ^{2}+(10-2) ^{2}  } = \\ = \sqrt{6 ^{2} +8 ^{2} }= \sqrt{100}=10
Answer:
A ) Square root of the quantity of 10 minus 2 all squared plus 7 minus 1 all squared.

A - f(2x) <br> B - 1/2f(x) <br> C - f(1/2x) <br> D - 2f(x)
Ulleksa [173]

Answer:

A: f(2x)

Step-by-step explanation:

In this case it can be seen that the x values are being affected by this transformation. This means that we should look for points on f and g with the same y value but different x values. However in this case it is hard to pinpoint easy coordinates to work with. This is where process of elimination can help. We know it cant be B or C because if the dilation ratio is outside the function, the y values would be affected. That leaves it to A or D. We can see that g has shrunk from the original function. Shrinking along the x-values can be notated by the reciprocal of the factor of shrinking. In this case it looks like it shrunk down to half of the originals size. If we take the reciprocal of a half we get 2. Therefore if we plug that in we get:

f(2x)

the area of the rectangle 56cm. the length is 2cm more than x and the with is 5cm less than twice x. solve for x. round the near
sattari [20]
(x+2)(2x-5)=56

2x^2-5x+4x-10=56

2x^2-x-10=56

2x^2-x-66=0

2x^2-12x+11x-66=0

2x(x-6)+11(x-6)=0

(2x+11)(x-6)=0, since x is a measurement x>0 so:

x=6cm
