Figure ABCD is shown on the coordinate plane. Suppose a graphic designer wants to dilate the figure so that the resulting image has a smaller area than figure ABCD. Describe a way the designer can achieve this type of dilation.
Answers
Answer:
Step-by-step explanation:
If the dilated image is smaller than the original, then 0<k<1.
Meaning the scale factor is less than one, but greater than zero.
You would mulitply each coordinate by this scale factor - to obtain the coordinates of the dilated figure.
Let's choose [tex]\frac{1}2}[/tex].
In the original figure Point A = (-4,3) dilating by [tex]\frac{1}{2}[/tex] results in A' being (-2, 1.5). When you multiply each cooordinate (-4,3) by one half.
Applying the scale factor of one half to the other coordinates - yields these results.
Point B (4,3) becomes Point B' (2, 1.5)
Point C (-4,-4) becomes Point C' (-2,-2).
Point D (4, -4) becomes Point D' (2,-2)

The electricity consumption in a start-up company was 4 kwh per day. As the manpower increased, the consumption of electricity increased to 10 kwh per day. What is the percent of increase in the consumption of electricity at the start-up company?
Answers
Answer:
150%
Step-by-step explanation:
10-4 is 6, and that is how much it increased by. Now, you have to find what percentage is 6 out of 4. 6/4 is 1.5, so you would multiply 1.5 by 100 to make it into a percent. 1.5*100=150, so your answer is 150%.

A company has recently been hiring new employees. Today the company has 32% more employees than it did a year ago. If there are currently 29,700 employees, how many employees did the company have a year ago?
Answers
the company a year ago had "x" employees, which oddly enough is the 100%.
now, today they have 32% more than that, well, 100% + 32% = 132%, and we know that's 29,700 employees
[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} x & 100\\ 29700& 132 \end{array} \implies \cfrac{x}{29700}~~=~~\cfrac{100}{132} \\\\\\ \cfrac{ x }{ 29700 } ~~=~~ \cfrac{ 25 }{ 33 }\implies 33x=742500\implies x=\cfrac{742500}{33}\implies x=22500[/tex]
