When the dilation is centered on the origin, you can multiply each of the individual coordinates by the scale factor.
All the coordinates are ±5 and the scale factor is 1/5. Multiplying those gives ±1. The only selection with all coordinates being ±1 is
.. Selection A.
You can check to see if the signs agree in detail. (They do.)
Answer:
Length = 12
Width = 6
Step-by-step explanation:
Width = 6 miles less than length;
L = L
W = L - 6
Area = 72 ft²
Area = Length * width
Area = (L * L-6)
Area = L² - 6L
-
L² - 6L = 72
L² - 6L - 72 = 0
L² - 12L + 6L - 72 = 0
L(L - 12) +6(L - 12) = 0
L = 12 or L = - 6
L cannot be negative
Width = L - 6
Width = 12 - 6 = 6
Hence,
Dimension of rectangle :
Length = 12
Width = 6
Answer:
radius r = 2.38732415 m
diameter d = 4.77464829 m
circumference C = 15 m
area A = 17.9049311 m2
Answer:
y=(2/3)x+1
Step-by-step explanation:
Slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.
To find the slope, we need two points. From the graph, we can see that (0,1) and (3,3) are valid points.
(0,1) is coincidentally also the y-intercept, so b=1.
The slope is (3-1)/(3-0)=2/3
The equation of the line is thus:
y=(2/3)x+1
There are a 100 cm in one meter so 6 m= 600 cm so 30 cm/ 600 cm = 1 cm/ 20cm or 0.05. Convert that into a percentage and you get 5%.
30cm is 5% of 6 m.
