Step-by-step explanation:
that is totally simple.
the area of a parallelogram is
baseline × height
basically the same as for a rectangle, just that in this more general form the height is no longer the other side.
in our case here
18×13 = 234 cm²
The slope m of a line passing through points P(a, b) and Q(c, d) is found using the formula:
![m= \frac{b-d}{a-c}](https://tex.z-dn.net/?f=m%3D%20%5Cfrac%7Bb-d%7D%7Ba-c%7D%20)
.
Thus, the slope in A is
![m= \frac{12-2}{-4-(-10)}=\frac{10}{6}=\frac{5}{3}](https://tex.z-dn.net/?f=m%3D%20%5Cfrac%7B12-2%7D%7B-4-%28-10%29%7D%3D%5Cfrac%7B10%7D%7B6%7D%3D%5Cfrac%7B5%7D%7B3%7D)
.
The slope in B is
![m= \frac{-4-10}{6-18}=\frac{-14}{-12}=\frac{7}{6}](https://tex.z-dn.net/?f=m%3D%20%5Cfrac%7B-4-10%7D%7B6-18%7D%3D%5Cfrac%7B-14%7D%7B-12%7D%3D%5Cfrac%7B7%7D%7B6%7D)
.
Now, to compare 7/6 to 5/3, we can write the second fraction as 10/6.
So, the slope in A is larger than the slope in B.
Answer: A
Answer:
Contradictrion
Step-by-step explanation:
First write an equation. If the total is 289, then that goes one the right side of the =. Sociology textbooks will be x. If there were 65 less than x, it will be 65-x. Lets set it up:
x + 65 -x =289
Then combine like terms.
65 = 289
There are no values of x that make the equation true. The input is a contradiction.

Answer: Our Cost function is discontinuous at every integer after x>10.
Step-by-step explanation:
Since we have given that
For the first 10 minutes , the service charges = $0.30
Let the number of additional minute be 't'.
Amount charge for each additional minute = $0.05
Using the greatest integer function:
So, Cost C of a call in terms of time 't' minutes would be
![C=0.03+0.05\left \lceil t-10 \right \rceil](https://tex.z-dn.net/?f=C%3D0.03%2B0.05%5Cleft%20%5Clceil%20t-10%20%5Cright%20%5Crceil)
As we know that Greatest integer is discontinuous at every integer.
So, our Cost function is discontinuous at every integer after x>10.
