Answer:

The slope between points T (9, -3) and U (-4, 1) is \mathbf{-\frac{4}{13}}

Step-by-step explanation:

We need to find the slope between points T (9, -3) and U (-4, 1)

The formula used to find slope is: Slope=\frac{y_2-y_1}{x_2-x_1}\\

We are given: x_1=9,y_1=-3, x_2=-4, y_2=1

Putting values and finding slope:

Slope=\frac{y_2-y_1}{x_2-x_1}\\\\Slope=\frac{1-(-3)}{-4-9} \\Slope=\frac{1+3}{-4-9} \\Slope=\frac{4}{-13}\\Slope=-\frac{4}{13}

So, slope between points T (9, -3) and U (-4, 1) is \mathbf{-\frac{4}{13}}

The length of a rectangle is one unit less than three times its width. Identify the graph that represents the relationship betwe
malfutka [58]

Answer:

The fourth graph

Step-by-step explanation:

Let x = width

The length is one less than 3 times the width, so length = 3x - 1

So we have a rectangle with length, 3x - 1, and width, x

So the area = y = (3x-1)(x)

So our equation:

y = (3x - 1)*(x)

If we check the x-intercepts, we see that y = 0 when x = 0 and 1/3.  The only graph that has (0,0) and (1/3, 0) is the fourth graph, making that one our graph.

1. Graph the six terms of a finite series where a1 = 5 and r = 1.25.
rodikova [14]
For the answer to the question above, asking to g<span>raph the six terms of a finite series where a1 = 5 and r = 1.25.
I'll provide the answer with the solutions below.
</span>a1 = 5 
<span>a2 = 5*r = 5*(5/4) = 25/4 </span>
<span>a3 = 5*r² = 5*(5/4)² = 125/16 </span>
<span>a4 = 5*r³ = 5*(5/4)³ = 625/256 </span>
<span>a5 = 5*r⁴ = 5*(5/4)⁴ = 3125/1024
</span>I hope this helps

A circle with radius 5 has a sector with a central angle of 9/10 pi
Solnce55 [7]

Answer:

35.33

Step-by-step explanation:

The circle with radius 5 has a sector with a central angle of 9/10 pi.

The area of a sector is given as:

A_s = \frac{\alpha }{2\pi} * \pi r^2

where α = central angle of the sector in radians

r = radius of the circle

The area of the sector is therefore:

A_s = \frac{\frac{9 \pi}{10} }{2 \pi} * (3.14 * 5^2)\\ \\A_s = \frac{9}{20} * 78.5\\\\A_s = 35.33

The area of the sector is 35.33.
