3 0

Answer:

c= 17

Step-by-step explanation:

c² = a² + b²

c= ?

a = 8

b= 15

c² = (8)² + (15)²

c² = 64 + 225

c² = 289

\sqrt{c ^{2} }  =  \sqrt{289}  \\  \\ c = 17

the rectangle shown has an area of 105 square inches. the width is x+ 16 inches and the length is x. find the dimensions of the
Brums [2.3K]

Answer:

Length = 5

Width = 21

Step-by-step explanation:

(x)(x + 16) = 105

x^2 + 16x = 105

x^2 + 16x - 105 = 0

(x - 5) x ( x + 21) = 0

x - 10 = 0

x = 5

x + 21 = 0

x = -21

Now that we have the zeroes.

We have to find the most viable one to put in.

Using -21 would not make sense, so we will use 5.

Plug it in:

x = 5

(5) (5 + 16) = 105

5 ( 21) = 105

A system of inequalities is shown.
Doss [256]

The system of inequalities which is represented in the graph shown (see attachment) is:

  1. y ≥ x² -2x -3
  2. y ≤ x +3

<h3>What is an inequality?</h3>

An inequality can be defined as a mathematical relation that compares two (2) or more integers and variables in an equation based on any of the following:

  • Less than (<).
  • Greater than (>).
  • Less than or equal to (≤).
  • Greater than or equal to (≥).

<h3>What is a graph?</h3>

A graph can be defined as a type of chart that's commonly used to graphically represent data on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis.

By critically observing the graph which models the system of inequalities shown, we can infer and logically deduce the following points:

  • Both boundary lines on the cartesian coordinate are solid. Thus, the inequalities will both have the "equal to" sign.
  • The shading occurred above the quadratic boundary line. Thus, the inequalities below the linear boundary line is given by y ≥ x² + and y ≤ x +

In conclusion, we can infer and logically deduce that the system of inequalities which is represented in the graph shown (see attachment) is:

  1. y ≥ x² -2x -3
  2. y ≤ x +3

What is the volume of this sphere, rounded to the nearest WHOLE<br> NUMBER?
Alenkinab [10]

Answer:

B

Step-by-step explanation:

V = (4/3) pi r^3

V = 1.333 * 3.14 * 11^3

11^3 = 1331

V = 1.333 * 3.14 * 1331

V = 5572
