Answer:

The answer is

-  \frac{5}{2}  \\

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

m =  \frac{ y_2 - y _ 1}{x_ 2 - x_ 1}  \\

From the question the points are

(5.3) and(7,-2)

The slope

m =  \frac{ - 2 - 3}{7 - 5}  =  \frac{ - 5}{2}  =  -  \frac{5}{2}  \\

We have the final answer as

-  \frac{5}{2}  \\

Hope this helps you

Answer:

-2.5

Step-by-step explanation:

Slope (m) =  

ΔY

ΔX

=  

-5

2

= -2.5

θ =  

arctan( ΔY ) + 360°

ΔX

= 291.80140948635°

ΔX = 7 – 5 = 2

ΔY = -2 – 3 = -5

Distance (d) = √ΔX2 + ΔY2 = √29 = 5.3851648071345

Equation of the line:

y = -2.5x + 15.5

or

y =  

- 5 x

2

+  31

2

When x=0, y = 15.5

When y=0, x = 6.2

A stained glass window is going to be installed in a semi-circular opening, which is above a 30 inch wide door. If the stained g
xenn [34]
The answer is <span>$494.55</span>

Let's first imagine a circle and calculate its area and then reduce it in half for the area of a semi-circle. Since this opening is above <span>a 30-inch wide door, the circle will have a diameter of 30 inches.
The area of the circle (A) is:
A = </span>π · r²
where:
π = 3.14
r - radius: r = diameter ÷ 2 = 30 ÷ 2 = 15 inches

So, the area of the circle is:
A = π · r² = 3.14 · 15² = 706.5 inches²

The area of the semicircle is half of the area of the circle:
A1 = A ÷ 2 = 706.5 ÷ 2 = 353.25 inches²

Since  the stained glass window costs $1.40 <span>per square inch, for 353.25 square inches it will cost $494.55:
353.25 square inches * 1.40 $/square inch = $494.55</span>

Juli2301 [7.4K]

Answer:

12

Step-by-step explanation:

Length of a circle = circumference = 2πr = 24π

                                            Radius (r) = 24π/2π

                                                             = 12cm
