Answer:

C. ,. A.

Step-by-step explanation:

1°)to find the symmetry, you have to find the maximum/minimum point, so this point here is the (4,-1).

2°) here, you only have to see if the value of y (in the point of symmetry) is the maximum, oder the minimum.( minimum in this case)

il63 [147K]

Answer:

The width of the banner is 4 inch and the length of the banner is 28 inch

Step-by-step explanation:

Given

Length is seven times its width

Let the width be "X", then length would be 7X

The banner is of rectangular shape.

Its area is 112 square inches

$X* 7X = 112\\7X^2 = 112\\X^2 = 16\\X = 4$

Hence, the width of the banner is 4 inch and the length of the banner is 4*7 i.2 28 inch

valina [46]

Answer:

Option A. 11.15 in³

Step-by-step explanation:

The question is as following:

A snow cone is a tasty treat with flavored ice and a spherical bubble gum ball at the bottom. The radius of the cone is 1.75 inches, and its height is 3.5 inches. If the diameter of the bubble gum ball is 0.5 inches, what is the closest approximation of the volume of the cone that can be filled with flavored ice?

A.) 11.15 in³

B.) 11.22 in³

C.) 0.07 in³

D.) 33.67 in³

=========================================

Solution:

Volume of the cone = π r² h/3

Vcone = 3.14 * (1.75in)² * 3.5in/3

Vcone = 3.14 * 3.0625 in² * 1.167

Vcone = 11.22 in³

Volume of the gum ball = 4/3 * π * r³

Vball = 4/3 * 3.14 * (0.5in/2)³

Vball = 4/3 * 3.14 * (0.25in)³

Vball = 4/3 * 3.14 * 0.015625 in³

Vball = 0.065 in³

11.22 in³ - 0.065 in³ = 11.155 in³

The answer is option A. 11.15 in³
