Step-by-step explanation:
u have to count it
Answer:
yd^2
Step-by-step explanation:
Formula: ![A = \frac{pq}{2}](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7Bpq%7D%7B2%7D)
p = 7.5 + 7.5 = 15
q = 13 + 13 = 26
![A = \frac{26*15}{2}](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7B26%2A15%7D%7B2%7D)
A = 195
We have the following vectors:
u = (a, b)
v = (c, d)
We observe that the vectors form an angle of 90 degrees.
Therefore, the product u.v is equal to zero.
We have then:
u.v = (a, b). (c, d) = 0
u.v = ac + bd = 0
ac = -bd
Answer:
B) ac = -bd
Answer:
vertical stretch by factor of 10
Step-by-step explanation:
vertical stretch by factor of 10
Given :
Xanthe and Sarah together raised $302 .
If Xanthe raised $102 more than Sarah .
To Find :
The amount raised by Sarah .
Solution :
Let , amount raise by Sarah is x .
So , by the relation given , price raised by Xanthe is 102 + x .
Now , sum of their amount raised is :
![x+(x+102)=302\\\\2x=302-102\\\\x=\$100](https://tex.z-dn.net/?f=x%2B%28x%2B102%29%3D302%5C%5C%5C%5C2x%3D302-102%5C%5C%5C%5Cx%3D%5C%24100)
Therefore , the amount raised by Sarah is $100 .
Hence , this is the required solution .
