Which choice shows the coordinates of C’ if the trapezoid is reflected across the y-axis?
suter [353]
A reflection through the axis and is given by the following transformation rule:
 (x, y) -------> (-x, y)
 We have the following point:
 C = (5, 3)
 Applying the transformation rule we have:
 (5, 3) -------> (-5, 3)
 Therefore, C' is given by:
 C '= (- 5, 3)
 Answer:
 (-5, 3)

Find the height and slant height of the cone. Round your answers to the nearest whole number.
Elan Coil [88]

Answer:

Height = 4 cm and slant height = 5 cm

Step-by-step explanation:

Given that,

The surface area of the cone, A = 75.4 cm²

Radius, r = 3 cm

The surface area of the cone is given by the formula as follows :

A=\pi r^2+\pi rl

Put all the values,

75.4=3.14\times 3^2+3.14\times 3\times l\\\\75.4=28.26+9.42l\\\\75.4-28.26=9.42l\\\\47.14=9.42l\\\\l=\dfrac{47.14}{9.42}\\\\l=5\ cm

Also,

l^2=r^2+h^2\\\\h=\sqrt{l^2-r^2}\\\\h=\sqrt{5^2-3^2}\\\\h=4\ cm

Hence, the height of the cone is 4 cm and the slant height is 5 cm.
