Find the value of x and pls explain!!❤❤❤

Mathematics
1 answer:
AlexFokin [52]3 years ago

Answer:

x = 52 degrees.

Step-by-step explanation:

Here we make use of the fact that the interior angles of any triangle add up to 180 degrees.  Before this we must find an algebraic expression for interior angle RQS:  

Since angle RQS + x + 72 = 180 degrees, angle RQS is equal to 180 -72 - x, or 108 - x.

The sum of the three interior angles is then

108 - x + 90 + 34, or 232 - x degrees, and this sum must equal 180 degrees.

Then 232 - x = 180.  Solving for x, we get x = 52 degrees.

Identify the slope and the y intercept please
anyanavicka [17]

Answer:

m= 2 / 3  b= -2

Step-by-step explanation:

you have to look at the graph to find the y-intercept

then do this to find the slope

m =  

y2 - y1

x2 - x1

you plug in all the numbers to get

m=

<u>0+4</u>

3+3

(it would be 3 minus, negative 3 which looks like: 3- - 3 becomes 3+3)

m=

<u>4</u>

6

and simplified that would be

m= 2/3

Which equation represents a parabola that has a focus of (0, 0) and a directrix of y = 4?
Ray Of Light [21]

Answer:

x2=−8(y−2)

Step-by-step explanation:

Parabola is a locus of a point which moves at the same distance from a fixed point called the focus and a given line called the directrix.

Let P(x,y) be the moving point on the parabola with  

focus at S(h,k)= S(0,0)  

& directrix at y= 4

Now,  

|PS| = √(x-h)2 + (y-k)2

|PS| = √(x-0)2 + (y-0)2

|PS| = √ x2 + y2

Let ‘d’ be the distance of the moving point P(x,y) to directrix y- 4=0

  •   d= |ax +by + c|/ √a2 + b2
  •   d= |y-4|/ √0 + 1
  •   d= |y-4| units.

equation of parabola is:  

  • |PS| = d
  • √ x2 + y2 = |y-4|

Squaring on both sides, we get:  

  • x2 + y2 = (y-4)2
  • x2 + y2 = y2 -8y + 16
  • x2 = - 8y + 16
  • x2 = -8 ( y - 2)  

This is the required equation of the parabola with focus at (0,0) and directrix at y= 4.

Using simple mathematical operations, the missing values are as follows:

(B) Dijon Mustard: 18g

  • Increased by 20 = 360g

(C) Barbeque sauce: 70g

  • Increased by 5 = 350g
  • Increased by 20 = 1,400g

(D) Worcestershire sauce: 10.35g

  • Increased by 5 = 51.75g
  • Increased by 20 = 207g

(E) Kosher salt: 1.5g

  • Increased by 5 = 7.5g
  • Increased by 20 = 30g

(F) Ground black pepper: 2.3g

  • Increased by 5 = 11.5g
  • Increased by 20 = 46g

(G) Crushed red pepper: 1.15g

  • Increased by 5 = 5.75g
  • Increased by 20 = 23g

<h3>What do we mean by mathematical operations?</h3>
  • A mathematical "operation" is the process of calculating a value utilizing operands and a math operator.
  • There are predefined rules associated with the math operator's symbol that must be applied to the supplied operands or numbers.
  • The order of operations is a rule that outlines the proper steps to take when analyzing a mathematical equation.
  • We can recall the PEMDAS steps in the following order: Parentheses, Exponents, Multiplication, Division (from Left to Right), Addition, and Subtraction (from left to right).

So, we can calculate missing values as follows:

(B) Dijon Mustard: 18g

  • Increased by 20 = 18×20 = 360g

(C) Barbeque sauce: 70g

  • Increased by 5 = 70×5 = 350g
  • Increased by 20 = 70×20 = 1,400g

(D) Worcestershire sauce: 10.35g

  • Increased by 5 = 10.35×5 = 51.75g
  • Increased by 20 = 10.35×20 = 207g

(E) Kosher salt: 1.5g

  • Increased by 5 = 1.5×5 = 7.5g
  • Increased by 20 = 1.5×20 = 30g

(F) Ground black pepper: 2.3g

  • Increased by 5 = 2.3×5 = 11.5g
  • Increased by 20 = 2.3×20 = 46g

(G) Crushed red pepper: 1.15g

  • Increased by 5 = 1.15×5 = 5.75g
  • Increased by 20 = 1.15×20 = 23g

Therefore, using simple mathematical operations, the missing values are as follows:

(B) Dijon Mustard: 18g

  • Increased by 20 = 360g

(C) Barbeque sauce: 70g

  • Increased by 5 = 350g
  • Increased by 20 = 1,400g

(D) Worcestershire sauce: 10.35g

  • Increased by 5 = 51.75g
  • Increased by 20 = 207g

(E) Kosher salt: 1.5g

  • Increased by 5 = 7.5g
  • Increased by 20 = 30g

(F) Ground black pepper: 2.3g

  • Increased by 5 = 11.5g
  • Increased by 20 = 46g

(G) Crushed red pepper: 1.15g

  • Increased by 5 = 5.75g
  • Increased by 20 = 23g
