A - Area
V - Volume
A = 4piR^2
V = 1.33piR^3

With the info given, 289 = 4piR^2, making R = 4.8
Plug this into the volume formula, and you'll get 1.33*pi*(4.8^3), which equates to 463.3 cubic centimeters.

The vertex of this parabola is at (-3, -1). When the y-value is 0, the x-value is 4. What is the coefficient of the squared term

defon

Answer:

$\frac{1}{49}$

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) = (- 3, - 1), thus

y = a(x + 3)² - 1

To find a substitute (4, 0) into the equation

0 = 49a - 1 ( add 1 to both sides )

49a = 1 ( divide both sides by 49 )

a = $\frac{1}{49}$

y = $\frac{1}{49}$ (x + 3)² - 1

coefficient of the x² term is $\frac{1}{49}$

A display number cube measures 20 inches on a side. The sides are numbered 1-6. The odd numbered sides are covered in blue fabri

Masja [62]

There are six sides or faces of a cube, each measuring 20 inches. If even numbered sides are covered with red fabric, then a total of 60 inches of red fabric was used. This is based from 3 even numbered sides multiplied to 20 inches as a measurement of each side.
