Answer:

\frac{20}{29}

Step-by-step explanation:

Equation of unit circle is:

x^2 + y^2 = 1

Plug y = \frac{-21}{29} in above equation.

x^2 + \bigg( \frac{-21}{29}\bigg)^2 = 1\\\\x^2 +  \frac{441}{841} = 1\\\\x^2   = 1-\frac{441}{841}\\\\x^2   = \frac{841-441}{841}\\\\x^2   = \frac{400}{841}\\\\x  =\pm\sqrt{ \frac{400}{841}}\\\\x  =\pm\frac{20}{29}\\\\

Since, point P is in the fourth quadrant.

Therefore, x - coordinate should be positive.

\huge \red {\boxed {\therefore x  =\frac{20}{29}}} \\\\

Which system of linear inequalities Is represented by this graphed solution?
SashulF [63]

Answer:

y ≥ 3x - 1

y < -\frac{1}{2}x+2

Step-by-step explanation:

Let the equation of the solid line passing through (x', y') given in graph is,

y = mx + b

Here m = slope of the line

b = y-intercept

Slope of the solid line =

                                 m = \frac{3}{1}

                                 m = 3

y - intercept 'b' = -1

Therefore, equation of the line will be,

y = 3x - 1

Since, shaded (blue) area is above the line, inequality that will represent the solution area will be,

y ≥ 3x - 1

For the dotted line,

Slope of the line (m) = \frac{\text{Rise}}{\text{Run}}

                                  = \frac{-2}{4}

                                  = -\frac{1}{2}

y-intercept (b) = 2

Equation of the dotted line → y = -\frac{1}{2}x+2

Since, shaded (grey color) area is below the dotted line,

Inequality representing the solution area will be,

y < -\frac{1}{2}x+2

The figure is the net for a rectangular prism.
oksano4ka [1.4K]

Answer:

SA=544\ cm^2

Step-by-step explanation:

we know that

The surface area of a rectangular prism is equal to the area of its six rectangular faces

using the net

The surface area is equal to

SA=2[(16)(6)]+2[(16)(8)]+2[(8)(6)]

SA=192+256+96

SA=544\ cm^2

Why does your monthly payment go up if you reduce your down payment
charle [14.2K]

Answer:

When you buy expensive items with a loan, you often need to make a down payment to cover a portion of the purchase price. That initial payment is often critical for getting approved, and it can affect your borrowing costs throughout the life of your loan. As a result, it’s wise to understand how down payments work so you can choose the right down payment amount.
