[When you are dividing or multiplying, the number of significant digits in the answer depends on the part of the question with the least significant digits. For example, There are 2.3 miles left for me to walk. but I can only do 1.54 miles. In the answer I will put two significant digits because the least was 2.3 which has 2 significant digits.]
#1 The answer is 4.821. but since the least # of significant digit is 1.5 which has 2. SO the Ans would be 4.8 mm^2.
#2 Ans is 2.7404 but the correct answer would be 3. because 5 has least value of significant digit. But why is 3? Because the number after 2 is greater than 7.
I hope that helps!

Answer : option B
This graph shows the solutions to the inequalities
system of inequalities y>3x+14 and y<3x+2
the system of inequalities have solutions only when the shaded part satisfies the given inequalities
We are given with the graph of inequalities . The given inequalities have 'and' in between.
so we look at the graph where both inequalities intersects
From the graph we can see that there is no intersection part of both shaded portions
So , we conclude that there is no solution.
Answer:
Option D)
Step-by-step explanation:
Given:
x= {2,3,4}
y={49,343,2401}
Points with coordinates (x,log(y)) are required to be plotted
Finding (x,log(y)):
log(y)= {log(49),log(343),log(2401)}
Log(49)=1.69020
log(343)=2.53529
log(2401)=3.38039
Now the transformed data set will be written in coordinates form:
(2,1.690),(3,2.535),(4,3.380)
Which is option D !
