The mass of the gold bar is = 13.896 kg.
To acheive this answer you have to multiply the area of the trapezium and the length of the bar. Hope this helped x :)
Answer:
f(x) > h(x) > g(x)
Step-by-step explanation:
For the average rate of change of a function between x = a and x = b,
Average rate of change =
From the table given,
Average rate of change of function 'f' between x = 1 and x = 3,
Average rate of change =
=
= 4
For the function 'g',
g(x) = 2x² - 18x
Average rate of change =
g(3) = 2(3)²- 18(3)
= 18 - 54
= -36
g(1) = 2(1)² - 18(1)
= 2 - 18
= -16
Therefore average rate of change =
= -10
From the graph attached,
Average rate of change of the graph between x = 1 and x = 3,
Average rate of change =
h(3) = 7.5 [Although the graph is not clear]
h(1) = 2
Average rate of change =
= 2.75
Therefore, order of rate of change (from greatest to the least) for the given functions will be,
f(x) > h(x) > g(x)
Answer:
y=15x+126
Step-by-step explanation:
the slope is
15 because -8-(-9) is 1 and 6-(-9) is 15 and y is over x so slope 15
To find y intercept start from -8,6 and add 15 to the y value every time you add one to the x value
you will add 8 times and you get 126 as the intercept
