Identify a sequence of transformations that maps triangle ABC onto triangle A"B"C" in the image below.
Murljashka [212]

Answer:

The correct option is B.

Step-by-step explanation:

It is given that triangle A"B"C" is the image of triangle ABC after transformation.

From the given figure it is noticed that the point C lies on positive y-axis and point C" lies on negative x-axis.

It means the figure is rotated either counterclockwise 90° or clockwise 270°. The rotation rule is

(x,y)\rightarrow (-y,x)

The corresponding sides of image A"B"C" are smaller than the preimage ABC.  

k=\frac{A"B"}{AB}=\frac{3}{6}=\frac{1}{2}

Since k<0, therefore the transformation shows the reduction. The dilation rule is

(x,y)\rightarrow (-\frac{1}{2}y,\frac{1}{2}x)

A(-3,0)\rightarrow (-\frac{1}{2}(0),\frac{1}{2}(-3))\rightarrow (0,-1.5)

B(3,0)\rightarrow (-\frac{1}{2}(0),\frac{1}{2}(3))\rightarrow (0,1.5)

C(0,5.2)\rightarrow (-\frac{1}{2}(5.2),\frac{1}{2}(0))\rightarrow (-2.6,0)

Option B is correct.

sasho [114]

Answer:

98

The answer is 98 because since the farmer's market sold 35% of its produce and has 280 peaches remaining you have to turn 35% into a decimal which is 0.35 then multiply that times 280 and get 98.

Answer:

Measure of ∠B = 51°.

Step-by-step explanation:

The sum of the measures of any triangle will always add up to 180°.  Also the sum of two supplementary angles, or angles that are side by side on a straight line, will also add up to 180°.  In order to find the measure of ∠B, you need to first find the measure of ∠C.  ∠C is supplementary to the angle of 113°, so we can find ∠C: 180 - 113 = 57°.  Now that we know ∠A and ∠C, we can solve for ∠B:  180 = 72 + 57 + ∠B or 180 = 129 + ∠B, subtracting 129 from both sides, we get ∠B = 51°.
