Which is the midpoint of the segment joining (12, 2) and (-5, – 7)?

Rainbow [258]

Answer:

$m(x, y)=(\frac{7}{2} , -\frac{5}{2} )$

Step-by-step explanation:

Midpoint of line segment is calculated as

$m(x, y)=(\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2} )$ -----------(1)

Here

$(x_1, y_1) = (12,2) \ \ and \ \ (x_2, y_2) = (-5, -7)$

Substituting values in equation (1)

$m(x, y)=(\frac{12-5}{2} , \frac{2-7}{2} )$

$m(x, y)=(\frac{7}{2} , -\frac{5}{2} )$

Calculate the surface area of the prism. Measurements are in centimetres

Nata [24]

Answer:

2804 cm²

Step-by-step explanation:

Total area comprises of 6 faces: 2 trapezoids and 4 rectangles

Trapezoid = 1/2*(14+32)*24 = 552 cm² each
Bottom = 17*32 = 544 cm²
Top = 14*17 = 238 cm²
Right side = 17*24 = 408 cm²
Left side = 17*√((24² + (32-14)²) = 17* √900 = 17*30 = 510 cm²

Total area:

552*2 + 544 + 238 + 408 + 510 = 2804 cm²
