4 0

Step-by-step explanation:

Use the sine and cosine trig functions

21) cos(52)=13/x

x=13/cos(52)

x=21.1

22) sin(75)=6/x

x=6/sin(75)

x=6.2

Which is an equation of a line parallel to -2/3x + 1/5y = 4
IrinaVladis [17]

Answer:

y = 3.3x + 20

Step-by-step explanation:

-2/3x +1/5y = 4   y = mx + b

-2/3x + 1/5y = 4

-2/3                -2/3

1/5y = 2/3 + 4

1/5  / 2/3 = 3.3

1/5 / 4 = 20

y = 3.3x + 20

Please Help Me Asap I Need Units Too
Lina20 [59]

Hello and Good Morning/Afternoon

<u>Let's take this problem step by step</u>:

<u>To find the rate of change is essentially like finding a line's slope</u>:

 ⇒ the <em>x-values</em> are the <em>number of sodas</em>

 ⇒ the<em> y-values </em>are the <em>total costs</em>

<em>               ⇒ choose</em> two sets of coordinates and find the slope

<u>Let's put that into action</u>

  • Choose any two points

        ⇒ (24, 18)

        ⇒ (28, 21)

  • Calculate Slope

        Rate_.of_.change = \frac{21-18}{28-24} =\frac{3}{4}

<u>Since the rate of change is total cost over number of sodas</u>

 ⇒ <em>unit is '</em>total cost/number of sodas'

<u>Answer: 3/4 total cost/number of sodas</u>

<u></u>

Hope that helps!

The solutions for the quadratic equation are given as follows:

x = -1, x = 7/5

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

A quadratic function is given according to the following rule:

y = ax^2 + bx + c

The solutions are:

  • x_1 = \frac{-b + \sqrt{\Delta}}{2a}
  • x_2 = \frac{-b - \sqrt{\Delta}}{2a}

In which:

\Delta = b^2 - 4ac

For this problem, the equation is:

5x² - 2x - 7 = 0.

Hence the coefficients are a = 5, b = -2 and c = -7, and then the solutions are found as follows:

  • \Delta = (-2)^2 - 4(5)(7) = 144
  • x_1 = \frac{2 + \sqrt{144}}{10} = \frac{7}{5}
  • x_2 = \frac{2 - \sqrt{144}}{10} = -1

The solutions are:

x = -1, x = 7/5
