Two triangles are said to be congruent when the have the same sides and the same angles. When a figure is dilated by a value, the size of that figure changes.
Therefore, when Triangle MNO is reflected across the y-axis and then dilated by a scale factor of 1.8 to form triangle MꞌꞌNꞌꞌOꞌꞌ, the two triangles are similar but not congruent.

Choose the point-slope form of the equation below that represents the line that passes through the point (−1, 6) and has a slope

IrinaVladis [17]

Answer:

The correct answer is option B.

Step-by-step explanation:

Two point form of the equation:

$(y-y_1)=\frac{y_2-y_1}{x_2-x_1}\times (x-x_1)$

$\frac{y_2-y_1}{x_2-x_1}=Slope=m$

$(y-y_1)=m\times (x-x_1)$

A line passing through the point (-1,6) with slope ,m = -3.

The equation of the line will be:

$y-6=(-3)(x-(-1))=(-3)(x+1)$

Hence, the correct answer is option B.

A construction worker is filling a container in the shape of a right circular cylinder with cement. the container has a base dia

kirza4 [7]

The volume of this container is 5990 feet³.

<h3>How to calculate the volume?</h3>

Volume of a cylinder = πr²h

π = 3.14

r = radius = 17.5/2 = 8.75

h = 24.5

The volume will be:

= πr²h

= 3.14 × 8.75² × 24.5

= 5990 ft³

Therefore, the volume of this container is 5990 feet³.
