And could someone please help me with this one please

Answer:

C

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

here (h, k) = (5, 2), thus

y = a(x - 5)² + 2

To find a substitute (4, - 3) into the equation

- 3 = a + 2 ⇒ a = - 3 - 2 = - 5

y = - 5(x - 5)² + 2 ← in vertex form

Expand (x - 5)² and distribute by - 5

y = - 5(x² - 10x + 25) + 2

  = - 5x² + 50x - 125 + 2

  = - 5x² + 50x - 123 ← in standard form

Cone A has a radius of 12 inches and cone b has a radius of 30 inches. if the cones are similar and the volume of cone a is 48 f
fiasKO [112]

Answer:

750ft^3

Step-by-step explanation:

Given:

Volume of cone a=48ft^3

Radius of a=12 inches

Radius of b=30 inches

Volume of cone b=?

The linear state factor=ratio of the radio

=30/12

=2.5

Volume scale factors=linear state factor^3

=2.5^3

=15.625

Volume of Cone B= volume of Cone A × volume scale factor

=48 × 15.625

= 750 ft^3
