Answer:
The answer is below
Step-by-step explanation:
The equation of a linear function is given as:
y = mx + b;
where y, x are variables, m is the rate of change and b is the initial value of variable y.
A) Since there is B bacteria in the Petri dish at 12:00 midnight and the number of bacteria increases after midnight by 25 every hour. Let h represent the time in hours and T represent the total number of bacteria, therefore the equation is:
T = 25h + B
B) Given that B = 5, h = 6, hence:
T = 25(6) + 5 = 150 + 5 = 155 bacteria
C) The equation of the graph is:
T = 25h + 5
The graph was plotted using geogebra online graphing.
Hi, here is the solution...
Part B)
The Navy Pier Ferris has the circumference is 56% of the circumference of the first Ferris wheel.
The Navy Pier Ferris Circumference = 439.6 feet
Let's assume "x" be circumference of first Ferris wheel.
56% of x = 439.6
0.56 x = 439. 6 [56% = 0.56]
x = 439.6/0.56
x = 785.
Therefore, the circumference of the first Ferris wheel is 785.
It is diameter = 785/3.14 = 250 feet
So it is radius = 250/2 = 125 feet.
Part C)
The circumference = 785 feet
Speed = Distance/Time
Speed = 785/9
Speed = 87.2 feet per minute.
That's it. Hope you will understand the steps.
Thank you. :)
Suppose we have two points, A= (1,2) and B=(2,5)
We need to divide the line segment AB obtained by joining these 2 points, in a ratio 2:3,
Then, to find the coordinates of the point (x,y) which will divide the line segment AB (x1,y1) and (x2,y2) we will use the formula,
x=(mx1 + nx2)/(m+n)
y=(my1 + ny2)/(m+n)
Where m:n is the ratio in which it divides
Thus, coordinates will be x= (2*1 + 3*2)/(2+3)
Or x = 8/5
And y = (2*2 + 5*3)/(2+3) = 19/5
Thus the coordinates of the point are (8/5, 19/5) which divide the line in 2:3 formed by coordinates (1,2) and (2,5)
A number that can be expressed as a fraction with integer values in the numerator/denominator.
