the vertices of triangle PQR are P(-3, 8), Q(-6, -4), and R(1, 1). If you reflect triangle PQR across the x-axis, what will be t

otez555 [7]

Answer:

The coordinates of the vertices of the image will be:

P'=(-3,-8)

Q'=(-6,4)

R'=(1,-1)

Step-by-step explanation:

If you reflect a point P=(x,y) across the x-axis, the coordinates of the image will be P'=(x,-y), then:

P=(-3,8)=(xp,yp)→xp=-3, yp=8→P'=(xp,-yp)→P'=(-3,-8)

Q=(-6,-4)=(xq,yq)→xq=-6, yq=-4→Q'=(xq,-yq)=(-6,-(-4))→Q'=(-6,4)

R=(1,1)=(xr,yr)→xr=1, yr=1→R'=(xr,-yr)→R'=(1,-1)

Find the area of a regular polygon

Law Incorporation [45]

Answer: Area of the polygon is 43.31 cm^2 t

Step-by-step explanation:

The polygon show in the diagram is a hexagon. It has six sides, since it is a regular hexagon, all the six sides are equal.

From the information given, the apotherm = 5√3

The apotherm is the perpendicular distance from the center of one side of the polygon to the center of the polygon. To determine the area of the polygon,

Area of polygon

=area = a^2n ×tan 180/n

Area = (5√3)^2 tan(180/6)

Area = 5^2×(√3)^2 × tan30

Area = 25×3×0.5774

Area = 43.305

Approximately 43.31 cm^2 to the nearest tenth

A tile backsplash is being installed. The installation fee is $150.00. The tile is priced at $2.75 per square foot, x. which equ

nirvana33 [79]

Answer: y = 150 + 2.75x

Step-by-step explanation:

Since we are informed that the installation fee is $150.00 and that the tile is priced at $2.75 per square foot, x, the total cost, y, of the backsplash will be the addition of the fixed cost of $150.00 plus $2.75 multiplied by the number of square foot. This will be expressed as:

y = 150 + 2.75x

where,

x = number of square foot.
