Answer:
b
Step-by-step explanation:
<span>y = 2x + 20. The answer is A. Explanation: Vlad spends a known amount of time on his history homework (20). On top of it, he also spends an unknown amount of time on solving a number of math problems (x). Each problem takes two minutes to solve, so the amount of time that he spends solving math problems is 2*x or 2x. In total (y), Vlad spends 20 + 2x amount of time on his homework. So y = 2x + 20, where y is clearly greater or equal to 20 and x is greater or equal to 0.</span>
Answer:
Yes, the graph makes it appear as if sales increased three folds.
Step-by-step explanation:
The graph presented by the advertising company is misleading, as it attempts to exaggerate the effect of its advert on sales. This can be attributed to the scale which is isn't uniform.
Last year sale was about 137000 and it grew to 150000 as a result of advertisement.
But from the bar chart, it seems there was three times increase in sales.
Answer:
g(x) = x² - 3
Step-by-step explanation:
A quadratic function has been given as,
f(x) = x²
If the function f is translated by 'h' unit down over the y-axis, the new function obtained by the translation is,
g(x) = x² - h
From the graph attached, h = 3 units (shift of 3 units downwards)
Therefore, g(x) = x² - 3 will be the translated version of f(x).
A. total power usage PS4 in a week = 8.8 watts x 21 hrs/day x 7 days/week
= (1293.6 watt.hr/week) / (1 kW/1000w)
= 1.29 KW hr/ week
b. carbon emission = 2.1lb/KW
= 1.29 KW x 2.1lb/KW
= 2.71 lb
