To graph the inequality:

Equation of the tangent to the curve at point (-1,1) is: y=2x+3

Given,

x=cos(t)+cos(2t)

y=sin(t)+sin(2t)

P(-1,1)

For the point(-1,1), the value of t satisfy the equations x=cos(t)+cos(2t) and y=sin(t)+sin(2t) is pi/2.

To find an equation of the tangent to the curve at the given point (x,y) where x=cos(t)+cos(2t) and y=sin(t)+sin(2t) and t= pi/2, we need to first find the slope of the tangent line at this point. To do this, we need to take the derivative of the x and y functions with respect to t:

dx/dt = -sin(t) + 2sin(2t)

dy/dt = cos(t) - 2cos(2t)

Now we can use this information to find the slope of the tangent line at the given point (x,y) where x=cos(t)+cos(2t) and y=sin(t)+sin(2t) and t= pi/2:

slope = dy/dx = (cos(t) - 2cos(2t)) / (-sin(t) + 2sin(2t)) evaluated at t = pi/2

slope = (cos(pi/2) - 2cos(2pi/2))/(-sin(pi/2) + 2sin(2pi/2)) = 0 - (-2)/0 + 0 = 2

Now, we can use this slope to find the equation of tangent using:

(y-y1)= m(x-x1)

=> y-1=2(x+1)

=>y=2x+3

Answer:

The slope is 1/2

Step-by-step explanation:

To find the slope of the line, put the equation in slope intercept form.

y= mx+b where m is the slope and b is the y intercept

4y -2x = -30

Add 2x to each side

4y -2x+2x = 2x-30

4y = 2x-30

Divide by 4

4y/4 = 2x/4 -30/4

y = 1/2x -15/2

The slope is 1/2

Answer:

0.5

Step-by-step explanation:

To find the slope of the line you have write this in slope intercept form.

That is,

Here,

m - Slope

c - y intercept

Now, to write this expression in slope intercept form, you have to make y the subject of this expression.

[tex] 4y - 2x = - 30[/tex]

Add 2x to both sides.

4y = 2x - 30

Now divide both sides by 4.

y = 2/4x - 30/4

Accordingly,

[tex]y = 0.5x - 7.5[/tex]

Slope of the line (m) = 0.5

Answer:  -2 1/2

Step-by-step explanation

if the equation is + but a number is negative, remember that +- = - which means 5/12 + (-2 11/12) = 5/12 - 2 11/12

2 11/12 is bigger than 5/12, so we'll switch it around and it'll become

2 11/12 - 5/12

2 11/12 - 5/12 = 2 6/12

Because 2 11/12 is originally a negative number, +- = -

which means the answer will be negative, so it is  -2 6/12.

but we're not done yet, we need to simplify it by dividing it with 6

so the final answer is -2 1/2

if it didn't make any sense at all heres an equation version :

5/12 + (-2 11/12)

= 5/12 - 2 11/12

= 2 11/12 - 5/12

= 2 6/12 (2 11/12 is originally negative so the ans will be negative)

= - 2 6/12 (divide by 6 to simplify)

= - 2 1/2

Write down the difference you found when subtracting the sum of the two angles from 180 degrees. This is the value of X.

Thus, all angles are equivalent to 60 degrees.

So, for a triangle, we know that Interior angle + neighbouring outside angle = 180°, 60° + x = 180°, and x = 180° - 60° = 120°.

Thus, a triangle's x value is 120°.

Answer: 61 cm.

Step-by-step explanation: The perimeter of any shape is the total distance of the exterior. This means that the sum of all side lengths of a shape is the perimeter. For a rectangle, the sum of both lengths and widths is the perimeter.

You can use the formula 2L+2W=P to solve this problem. 308 is P or the perimeter and 93 is L or the length. We can substitute these values and we get 2(93)+2(w)=308. We then subtract 2(93) or 186 from both sides to get 2W= 122. We then divide by two to get W or the width is equal to 61 cm.

The solution of the given system of equations is (-2, -2).

What is addition method?

Using the Addition Method to Solve Systems of Equations in Two Variables. The addition method, also known as the elimination method, is a third strategy for resolving linear equation systems. With this approach, we add two terms that share the same variable but have opposing coefficients, resulting in a sum of zero.

Consider, the given system of equations

-5x - 9y = 28             ..(1)

-4x + 5y = -2              ..(2)

Multiply equation (1) by 5 and multiply equation (2) by 9.

-25x - 45y = 140         ..(3)

-36x + 45y = -18          ..(4)

Adding equation (3) and (4), we get

     -25x - 45y = 140

+   -36x + 45y = -18

______________________

     -61x + 0  = 122

-61x = 122

   x = -2

Plug x = 2 in equation (1)

-5(-2) - 9y = 28

    10 - 9y = 28

           9y = -18

             y = -2

Hence, the solution of the given system of equations is (-2, -2).

The area of the hexagon is approximate, Area = (150 √3) m².

What is a formula of a hexagon?

A Regular hexagon has six sides and angles that are congruent and is made up of six equilateral triangles. The formula to find out the area of a regular hexagon is as given:

Area = (3√3 s²)/ 2

where 's' represents the length of a side of the regular hexagon.

A hexagon is a six-sided polygon. The area of a hexagon can be calculated using the formula:

Area = (3 * √3 * (side length)^2) / 2

In this case, the hexagon is 10m by 5m, so the side length of the hexagon is 10m. Plugging this into the formula, we get:

Area = (3 * √3 * (10m)^2) / 2

Area = (3 * √3 * 100m^2) / 2

Hence, the area of the hexagon is approximate:

The equation of the square coop is 4x = 20 and the length is 5yd .

What is equation ?

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

A mathematical statement known as an equation is made up of two expressions joined together by the equal sign. A formula would be 3x - 5 = 16, for instance. When this equation is solved, we discover that the value of the variable x is 7.

A mathematical expression with an equals sign is referred to as an equation. Algebra is widely used in equations. When performing calculations but unsure of the precise amount, algebra is used.
