Answers

The measure of the trigonometric relations is tan θ = -1 when the reference angle θ = 315°

What is Reference Angle?

Every angle is measured from the positive part of the x-axis to its terminal line (the line that determines the end of the angle) traveling counterclockwise. For angles in the first quadrant, i.e., angles less than or equal to 90 degrees, the reference angle is equal to the original angle.

The reference angle is always positive

0° to 90°: reference angle = angle

90° to 180°: reference angle = 180° - angle

180° to 270°: reference angle = angle - 180°

270° to 360°: reference angle = 360° - angle

Given data ,

Let the reference angle be represented as R

Now , the value of R is R = 315°

And , the measure of angle θ = 7π/4

The reference angle θ = 315°

So , the value of tan ( 315 )° = -1

Hence , the trigonometric value tan ( 7π/4 ) = -1

[tex]x=80^{\circ},\\y=80^{\circ}[/tex]

Step-by-step explanation:

The measure of an angle formed by a secant and a tangent outside of a circle is half of the absolute difference between the two arcs it forms. Therefore, we have the following equation:

[tex]m\angle A=\frac{\widehat{BC}-\widehat{BD}}{2}[/tex]

Substituting given values, we get:

[tex]20=\frac{120-x}{2},\\40=120-x,\\x=\boxed{80^{\circ}}[/tex]

Since there are 360 degrees in a circle, we can write the following equation, using [tex]x[/tex], to solve for [tex]\widehat{DC}[/tex]:

[tex]x+\widehat{DC}+120=360,\\80+\widehat{DC}+120=360,\\\widehat{DC}=\boxed{160^{\circ}}[/tex]

The value of the angle formed by a chord and a tangent is half the measure of the arc it forms. Therefore,

[tex]y=\frac{\widehat{DC}}{2}=\frac{160}{2}=\boxed{80^{\circ}}[/tex]

This inserts an equation placeholder where you can type your equation. Select the equation you want to add. Choose the down arrow and select Save as New Equation....
If you need the pi sign just look up a copy and paste version of it.

But you type it how you write it other then that .

What are the coordinates of the turning point of the parabola whose equation is y=-x^2+4x+1

PLEASEEE ANSWERRRRRR

Answers

Answer:

The maximum of the parabola lands at (2,5).

The coordinates of the turning point of the parabola whose equation is y=-x²+4x+1 are (2, 5)

What is Coordinate system?

A coordinate system is a system that uses one or more numbers, or coordinates, to uniquely determine the position of the points.

The equation of Parabola is y=-x²+4x+1

The turning point (vertex) is the point where the derivative is equal to zero.

y=-x²+4x+1

Differentiate the equation

dy/dx=-2x+4

Now equate dy/dx with zero

dy/dx=0

-2x+4=0

-2x=-4

x=2

Now put x value in the equation

y=-(2)²+4(2)+1

y=-4+8+1

y=5

Hence the coordinates of the turning point of the parabola whose equation is y=-x²+4x+1 are (2, 5)

Solve for x: 2(x + 4) + 6 = 12x - 8

Answers

Answer:

x = 2.2

Step-by-step explanation:

2(x+4)+6 = 12x-8

Use distribution property

2x+8+6 = 12x-8

Combine like terms

2x+14 = 12x-8

Subtract 14 from both sides

2x = 12x-22

Subtract 12x from both sides

-10x = -22

Divide both sides by negative 10

x = 2.2 or x = 11/5 in fractions.
