Answer:
Step-by-step explanation:
Slope m = rise / run = ( - ) / ( - )
<em>1).</em> (-4,3)
(4, - 1)
m = (-1 - 3) / (4 + 4) = <em>- 1/2</em>
<em>2).</em> (-1, 1)
(2, - 5)
m = (- 5 - 1) / (2 + 1) = <em>- 2</em>
<em>3).</em> (6, 4)
(5, 4)
m = (4 - 4) / (5 - 6) = <em>0</em> (graph is horizontal line)
<em>4).</em> (1, 4)
(4, 1)
m = (1 - 4) / (4 - 1) = <em>- 1</em>
<em>5).</em> - 3/4
<em>6).</em> 4/3
<u><em>Now is your turn. You can do it!!!</em></u>
<em>7).</em> (1, 1)
(2, 2)
m = ____
<em>8).</em> ( __ , __ )
( __ , __ )
m = _____
<em>9).</em> (0, 2)
(0, 4)
m = (4 - 2) / <u><em>(0 - 0)</em></u> = undefine slope or <em>no slope</em> (graph is vertical line)
<em>10).</em>
Answer:
264 cm^2
Step-by-step explanation:
Area of a trapezoid = 1/2 (b1+b2) *h
The area of the large trapezoid
b1 = 14 b2 = 25 h = 10+12 = 22
A = 1/2 (14+25) *22 = 429 cm^2
The area of the unshaded trapezoid
b1 = 8 b2 = 25 h = 10
A = 1/2 (8+25) *10 = 165 cm^2
To find the area of the shaded region, take the area of the large trapezoid and subtract the unshaded trapezoid
429 - 165 =264 cm^2
Answer:
d = m / v.
Step-by-step explanation:
The density is a measure of the specific weight of a substance or object.
This is, the mass per unit of volume. Then, the average density is the ratio of the mass of a body to the volume it occupies in space:
The equation for density is:
being m the total mass in the volume, and V the volume.
the transformation (x, y) → (x, y- 4) , means the x-coordinate remains unchanged, while the y-coordinate has 4 subtracted from it, for example
the points on the diagram
A(1, 5 ) → A'(1, 5 - 4) → A'(1, 1)
B(4, 5) →B'(4, 5 - 4) → B'(4, 1)
C(4, 3) → C'(4, 3 - 4) → C'(4, - 1)
D(2, 2) → D'(2, 2- 4) → D'(2, - 2)
