1) The scale factor is 0.25 is true.
Step-by-step explanation:
Step 1:
The first figure is dilated to form the second figure. The shape is a rhombus.
It is given that the side length of the first figure is 5.8 and the side length of the second figure is 1.45.
Step 2:
To calculate the scale factor, we divide the measurement after scaling by the same measurement before scaling. In this case, it is the side length of the rhombus.
The scale factor 
So the scale factor is 0.25. This is the first option.
Quadratic functions are second-order equations of the form y=ax^2+bx+c. Their graphs form parabolas. The defining characteristic of a quadratic is that the acceleration of the outputs is a constant.

Answer: B) -1/2</h3>
Explanation: Parallel lines have the same slopes, but different y intercepts.
<span>It is estimated that 5000 live bacteria existed in the sample before treatment. After each day oftreatment, 40% of the sample remains alive. Which best describes the graph of the function thatrepresents the number of live bacteria after x days of treatment? f(x) = 5000(0.4)x, with a horizontal asymptote of y = 0 f(x) = 5000(0.6)x ...</span><span>

Perimeter is 2 x length + 2 x width
We can write that as...
P=2L+2W
We also know the length and perimeter so we substitute and solve like this
90=2 x 27 + 2W
90=54+2W
90-54=54-54+2W (property of subtraction equality)
36=2W
Divide by 2 (property of division equality)
W=18
Thus, the width of the rectangle is 18 cm
