Answer:

\frac{3}{20}

Step-by-step explanation:

Well you can represent percentages as decimals, by dividing the percentage by 100. This gives us the fraction: \frac{15}{100}

We can simplify the fraction, by dividing both the numerator and denominator by 5

\frac{15}{100}=\frac{15\div5}{100\div5}=\frac{3}{20}

The surface area of a cube is 864 in.2. Find the volume of the cube
Sveta_85 [38]
As the cube has 6 faces the area of one face  will be 864 / 6 = 144 in^2

so each edge = 12 in  

Volume of cube = 12^3 =   1728 in^3

Solve using the quadratic formula. Show all work. Write each solution in simplest form. No decimals.
vagabundo [1.1K]

Answer:

A) -2 - i√3 , -2 + i√3

Step-by-step explanation:

Solve using quadratic formula

x² + 4x + 7 = 0

The Almighty Formula

= -b ± √b² - 4ac/2a

Where ax + bx² + c = 0

From the above question

a = 1, b = 4, c= 7

Hence,

-4 ± √4² - 4 × 1 × 7/2 × 1

-4 ± √16 - 28/2

=( -4 ± √-12)/2

Since

b² - 4ac < 0

We have two complex roots

Simplifying

( -4 ± √-12)/2

= -4/2 ± √-12/2

= -2 ± 2√3i/2

= -2 ± √3i

Therefore,

-2 - √3i , -2 + √3i

or

-2 - i√3 , -2 + i√3

Option A , is the correct answer

Identify the range of the function shown in the graph.
Vladimir [108]

Answer:

A

All real numbers

Step-by-step explanation:

Given in the question a graph

To find the range of graph

The range is the set of possible output values, which are shown on the y-axis.

We can see in the graph that for negative values of x it have positive values, zero and negative values of y.

The graph extends vertically from (-∞,∞), along the y axis. So the range of the function shown in the graph is (-∞,∞).  

Hence, it is concluded that range is All real numbers
