Weird that the only choices are given as integrals with respect to

. (Integration along the

axis would be way easier, but whatever)
The fourth option should do it.
Answer:
45
Step-by-step explanation:
98+37=135
180-135=45
The two circle designs are missing, so i have attached it.
Answer:
Options A & B are true.
Step-by-step explanation:
Congruent circles are basically identical. This means that they have the same radius and diameter but different centres.
Now, from the attached image, we see that the smallest circle in diogo's design has diameter of 2 units & radius of 1 unit while the one in Elena's design also has exactly the same measurement. Thus, we can conclude the smallest circle in diogo's design which is the first one is congruent to the smallest circle in the second design for Elena.
So option A is correct.
Looking carefully at both designs, we can observe that one is concentric while the other is eccentric. However, all the similar sized circles have the same radius & diameter. Thus, we can still say that both designs are congruent. So option B is correct.
In transformations, a translation is when all the points in a an object are made to move up or down in a state straight line in that same direction. However, the objects shape and size remains the exactly the same.
In this case, it's not so because the circle changed from concentric circles to eccentric circles. So this option C is not correct.
Answer:
1/8 of a minute
Step-by-step explanation:
Let the total time be t.
=> 1/2 x t = 1/16
=> t = 2/16
=> t = 1/8 of a minute
Answer:
4.13=4.130
If there is a 0 at the end of a decimal then you can drop it.
