Answer:

Step-by-step explanation:

when the two angles are added they are equal to 180 degree. (corresponding angles property)

x+8+3X+2=180

4X+10=180

4X=170

X=44.25 DEGREES

Question 1:

For this case we have that by definition, if a and b are two parallel lines, then the corresponding angles are congruent, that is, we can write 3x + 2 and x + 8 as supplementary angles:

(3x + 2) + (x + 8) = 180\\3x + 2 + x + 8 = 180\\4x + 10 = 180\\4x = 180-10\\4x = 170\\x = \frac {170} {4}\\x = 42.5

We look for the value of the angles:

3 (42.5) + 2 = 129.5\ degrees\\42.5 + 8 = 50.5 \ degrees

ANswer:

x = 42.5\\3 (42.5) + 2 = 129.5\ degrees\\42.5 + 8 = 50.5 \ degrees

Question 2:

For this case we have that by definition, the equation of a line of the slope-intersection form is given by:

y = mx + b

Where:

m: It's the slope

b: It is the cutoff point with the y axis

Now, in the equation y = 2x + 3

m = 2\\b = 3

By definition, if two lines are parallel, their slopes are equal. Also, if two lines are perpendicular, then the product of their slopes is -1.

So:

The slope of a line parallel to the given line is:

m = 3

The slope of a line perpendicular to the given line is:

3 * m = -1\\m = - \frac {1} {3}

ANswer:

3\\- \frac {1} {3}

<h3>Answer:</h3>
  • 6 large prints
  • 12 small prints
<h3>Step-by-step explanation:</h3>

<em>Numerical Reasoning</em>

Consider a set of prints that consists of 2 small prints and one large print (that is, twice as many small prints as large). The value of that set will be ...

... 2×$20 +45 = $85

To have revenue of at least $510, the studio must sell ...

... $510/$85 = 6

sets of prints. That is, the studio needs to sell at least 6 large prints and 12 small ones.

_____

<em>With an equation</em>

Let x represent the number of large prints the studio needs to sell. Then 2x will represent the number of small prints. Total sales will be ...

... 20·2x +45·x ≥ 510

... 85x ≥ 510

... x ≥ 510/85

... x ≥ 6

The studio needs to sell at least 6 large prints and 12 small prints.

Use logarithmic differentiation to find dy/dx
liq [111]

Answer:

dy/dx  =  (x^2 - 3)^sin x [2x sin x/ (x^2 - 3) + cos x ln(x^2 - 3)]

Step-by-step explanation:

y = (x^2 - 3)^sinx

ln y = ln  (x^2 - 3)^sinx

ln y = sin x * ln (x^2 - 3)

1/y * dy/dx  =   sin x * {1 / (x^2 - 3)} * 2x + ln(x^2 - 3) * cos x

1/y dy/dx =  2x sin x/ (x^2 - 3) + cos x ln(x^2 - 3)

dy/dx  =   [2x sin x/ (x^2 - 3) + cos x ln(x^2 - 3)] * y

dy/dx  =  (x^2 - 3)^sin x [2x sin x/ (x^2 - 3) + cos x ln(x^2 - 3)]

What is the measure of PSQ in degrees? Angle PSR measures 99°.
11111nata11111 [884]

we know that

Step 1

Find the value of x

m∠PSR=99°

m∠PSR=(3x+18)+(9x-27)°

so

99 =(3x+18)+(9x-27) \\ 99=12x-9\\ 12x=108\\ x=9degrees

Step 2

Find the value of m∠PSQ

m∠PSQ=(3x+18)

m∠PSQ=(3*9+18)

m∠PSQ=45°

therefore

the answer is the option

C) 45 degrees
