What is the area of the sail?

Mathematics

Area = 30 meters ^2

Area of a triangle is found by multiplying both sides and then dividing that answer by 2.

So 6 times 10 is 60, and 60 divided by 2 is 30.

In a right triangle, the acute angles have the relationship sin (2x+4)=cos(46).
Elis [28]

The required value of the acute angle x in a  right angle triangle is 20. Option A is correct.

Given that
In a right triangle, the acute angles have a relationship,

sin (2x+4) = cos(46)

To determine the value of x

<h3>What are trigonometric equations?</h3>

These are the equation that contains trigonometric operators such as sin, cos.. etc.. In algebraic operation.

sin (2x+4) = cos(46)  - - - - - -(1)

Since,
cos(46) = cos (90 - 44)
cos(46) = sin (44)

put it in equation 1

sin (2x+4) = sin (44)
2x + 4 = 44
2x = 44 - 4
2x = 40
x = 20

Thus, the required value of the acute angle x in a  right angle triangle is 20. Option A is correct.

Pls help! I'm confused. Can you explain this if you can.
alexdok [17]

Answer:

From a <u>table</u>, for an ordered pair (0, y), <em>y</em> will not be <u>zero</u>. From a <u>graph</u>, the y-intercept will not be <u>zero</u>.  From an equation, it will have the form, y = mx + b where b is <u>≠ 0</u>.

Step-by-step explanation:

  • From a <u>table</u>, for an ordered pair (0, y), <em>y</em> will not be <u>zero</u>. If there is not a constant rate of change in the data displayed in a table, then the table represents a nonlinear nonproportional relationship.
  • From a <u>graph</u>, the y-intercept will not be <u>zero</u>. This means that it doesn't contain or go through the origin.  
  • From an equation, it will have the form, y = mx + b where b is <u>≠ 0.</u> (not equal to zero). If an equation is not a linear equation, it represents a nonproportional relationship. A <u>linear equation</u> of the form y = mx + b may represent either a <em>proportional</em> (b = 0) or <em>nonproportional</em> (b ≠ 0) relationship.  Therefore, when b ≠ 0, the relationship between <em>x</em> and <em>y</em> is <u>nonproportional</u>.

Anybody know the right answer?
Murljashka [212]
Y = -1 is a horizontal line going through "-1" on the y axis

Note that the point (1,2) is exactly 3 units of distance above the line y = -1

When we reflect across this line, the point (1,2) will just move straight down to exactly 3 units of space below the line y = -1.  Since we are not shifting left or right, the x coordinate of our original point will not change.  The y coordinate of our original point will now need to be reduced by 6(3 units down to get to the line of reflection and then 3 more down to get to the image location)   

The coordinates of the image point will be (1, -4)
Now we need to do the same process with (1, -4) being reflected across y=1

Note (1,-4) is 5 units of distance below the line y = 1 , so we need to reflect the point upward so that the image point is located exactly 5 units of distance above the line y = 1  Again, the x coordinate does not change, and our final image coordinates are (1, 6)

I guess more simply stated, if you're just looking for the number in the green box it would be " 1 " .. Reflecting points across horizontal lines only result in changes of the "y" coordinate since there is no shift left or right.

The sides of a rectangle are 6.3 cm and 4.8cm, each correct to 1 decimal place.
Effectus [21]
Error= 0.1/2, 0.05

4.8 + 0.05 = 4.85
6.3 + 0.05 = 6.35

4.85 x 6.35 = 30.7975 cm (when rounded, gives 30.80 cm).

A certain drink is made by adding 4 parts water to 2.5 part drink mix. What percent of the mixture is water? Omit % sign in your
Maru [420]

The mixture contains 61.5% of water.

<u>Step-by-step explanation:</u>

Total parts = 4+ 2.5 = 6.5

Parts of water =4

parts of drink = 2.5

Percent of water in the mixture = 4 × 100/ 6.5

                                                     = 400/6.5

                                                      = 61.53%

It is rounded to the nearest tenth as 61.5%.
