QUICK !! <br> What is the image point of (2,-7) after a translation right 4 units and up 3 units ?

Paul [167]

Answer:

(6, - 4)

Step-by-step explanation:

A translation of 4 units right is equivalent to adding 4 to the x- coordinate

A translation of 3 units up is equivalent to adding 3 to the y- coordinate

(x, y) → (x + 4, y + 3) ← translation rule

Hence

(2, - 7) → (2 + 4, - 7 + 3) → (6, - 4)

An oval track is made by erecting semicircles on each end of a 46 m by 92 m rectangle. Find the length of the track and

Alexxandr [17]

Answer:

$Length\,\, of\,\, the\,\, track=420.44\,m\\\\Area\,\,covered \,\,by\,\, the\,\, track=5893.06\,m^2$

Step-by-step explanation:

Length of the Track:

Perimeter of the rectangle + Circumference of the two semicircle

Perimeter of the rectangle= $2(Length+Width)$

$Length=92\,m\\Width=46\,m$

Perimeter of the rectangle:

$=2(92+46)\\\\=2(138)\\\\=276\,m$

Circumference of Two Semicircle with same radius:

$r=\dfrac{46}{2} =23\,m$

$Circumference=2\times \pi \times r\\\\$

$=2\times 3.14\times 23\\\\=6.28 \times 23\\\\=144.44\,m$

Total Length of the track is :

$=276+144.44\\\\=420.44\,m$

Area Covered by the track is :

Area of the two semicircle + Area of the rectangle

$=(\pi \times r^2) + (Length\times Width)\\\\=(3.14\times (23\times 23 ))+(92\times 46)\\\\=1661.06 +4232\\\\=5893.06\,m^2$
