Which equation is y = 6x2 + 12x – 10 rewritten in vertex form?
kykrilka [37]
Y = 6 x² + 12 x - 10= 6 ( x² + 2 x ) - 10 = 6 ( ( x² + 2 x + 1 ) - 1 ) - 10=
6 ( x + 1 )² - 6 - 10 = 6 ( x + 1 )² - 16 ( vertex form)

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.
