Answer:
So 0.71 and 54 represent the same level of precision.
Step-by-step explanation:
Precision is how many significant figures have been measured. This is the number of digits in between the first and last non-zero digit.
In this case what we have:
1265.12 = 6 sig figs
0.71 = 2 sig figs
24.5 = 3 sig figs
54 = 2 sig figs
So 0.71 and 54 represent the same level of precision.
This is answer of your question and i hope you get the idea.
Answer:
-5
Step-by-step explanation:
y=-2/3-5x
Rewriting the equation in the form y = mx+b where m is the slope and b is the y intercept
y = -5x -2/3
The slope is -5 and the y intercept is -2/3
Answer:
x = 6.5
Step-by-step explanation:
5(x−2)+3x−4= 38
5 times x, 5 times -2 =
5x - 10 + 3x - 4 = 38
Combine like terms
5x + 3x = 8x
8x - 10 - 4 = 38
Add 10
8x -10 +10 -4 = 38 +10 =
8x -4 = 48
Add 4
8x -4 +4 = 48 +4
8x = 52
Divide by 8
8x/8 = 52/8 =
x = 6.5
Answer: y(t) = 600(0.921)^t
Step-by-step explanation:
Given:
Percentage yearly reduction = 7.9%
Initial mass m = 600 mg
time in years = t
An exponential function with yearly decay rate to determine the final mass of the substance is given as:
y(t) = m(f)^t
y(t) = final mass in milligram
m = 600
f = final mass fraction = 1 - 0.079 = 0.921
f = 0.921
Therefore, the exponential function is given as;
y(t) = 600(0.921)^t
