To solve this problem you must apply the proccedure shown below:

 1. You have that the ratio of the tangent function is:

 tan(angle)=opposite/adjacent

 2. Keeping this on mind, you have:

 tan(A)=12/5

 Therefore, the answer is: 

 tan(A)=12/5

Hello!

First you have to label the sides of the triangle

The hypotenuse is the longest side
The opposite side is the side opposite of the angle
The adjacent side is the third side

Find tangent you do opposite / adjacent

The opposite side is 12
The adjacent side is 5

Put in the numbers

The answer is D) 12/5

Hope this helps!

Which shows the correct substitution of the values a, b, and c from the equation 0 = – 3x2 – 2x + 6 into the quadratic formula?
AlexFokin [52]

An expression which shows the correct substitution of the values a, b, and c from the equation 0 = – 3x2 – 2x + 6 into the quadratic formula is: expression A. Therefore, the correct answer option is A.

<h3>What is a quadratic equation?</h3>

A quadratic equation can be defined as a mathematical expression (equation) that can be used to define and represent the relationship that exists between two or more variable on a graph. In Mathematics, the standard form of a quadratic equation is given by;

ax² + bx + c = 0

Mathematically, the quadratic formula is modeled or represented by this mathematical expression:

x = \frac{-b\; \pm \;\sqrt{b^2 - 4ac}}{2a}

From the information provided, we have the following values;

0 = -3x² - 2x + 6

Where:

a = -3

b = -2

c = 6

Substituting the values into the quadratic formula, we have;

x = \frac{-(-2)\; \pm \;\sqrt{(-2)^2 - 4(-3)(6)}}{2(-3)}\\\\x = \frac{2\; \pm \;\sqrt{4^2 - 4(-3)(6)}}{2(-3)}

At noise pollution cellular,plan A is $30.00 per month and $5.00 for every gigabyte of data . Plan B is $50.00 per month and $2.
Romashka-Z-Leto [24]
Let x be the number of gigabyte of data used.

Plan A:
Total cost = 30 + 5x

Plan B:
Total cost = 50 + 2x

Irfan will use between 5 to 8 gb of data per month.

When x = 5
Plan A = 30 + 5(5) = $55
When x = 8,
Plan A = 30 + 5(8) = $70

When x =5,
Plan B = 50 + 2(5) = $60
When x = 8,
Plan B = 50 + 2(8) = $68

He is probably better off using Plan A. Plan A is a cheaper option up to 7gb of data. He should only swap to Plan B if he consistently use 8gb or more data per month.

Answer:

-82, -83, -84

Step-by-step explanation:

Using a variable and corresponding expressions, we can set the sum of the consecutive integers equal to -249 and solve:

first integer: x

second integer: x + 1

third integer: x + 2

x + x + 1 + x + 2 = -249

Combine like terms: 3x + 3 = -249

Subtract 3 from both sides: 3x + 3 - 3 = -249 - 3  or 3x = -252

Divide both sides by 3: 3x/3 = -252/3

Solve for x: x = -84

first integer: -84

second integer: -84 + 1 = -83

third integer: -84 + 2 = -82
