Answer:
It's a direct variation, as the ratio between x and y is constant
Answer:
A) 5x²(x^8-16)
B) 5x²(x^4-4)(x^4+4)
Step-by-step explanation:
A) 5x² Is the greatest common factor.
5x²(x^8-16)
B) After taking out the greatest common factor, what’s left can easily be factored.
5x²(x^4-4)(x^4+4)
Answer:
a) (C∪P)-B
b) (U-B)∩(U-C)∩(U-P)
c) B∩C∩P
d) P-(B∪C)
e) (B∪C)-P
Step-by-step explanation:
We can use three operations between sets:
- Union: X∪Y is the set of elements that belong to X or belong to Y
- Intersection: X∩Y is the set of elements that belong to X and belong to Y
- Difference: X-Y is the set of elements that belong to X and NOT belong to Y.
The sets we can use in each part are U,B,C and P
a) A customer that likes corn dogs belongs to C, and a customer that likes pizza belongs to P, then a customer who likes corn dogs or pizza belongs to C∪P. The customers from this problem do not like burgers, so they don't belong to B. From this, the required set is (C∪P)-B
b) The customers do not like burgers, so they do not belong to B. However, they visit the restaurant so they belong to U. Thus, the customers belong to U-B. Similarly, because the customers do not like corn dogs and do not like pizza, they belong to U-C and U-P. Then the set of customers is (U-B)∩(U-C)∩(U-P).
c) The customers are in B, C and P so they belong to B∩C∩P.
d) The customers belong to P (they like pizza) but they do not belong to (B∪C), thus they belong to P-(B∪C)
e) The customers belong to B∪C but they do not belong to P, so the required set is (B∪C)-P.
Answer:
angle BCD = 108
Step-by-step explanation:
opposite angles in a cyclic quadrilateral add to 180
so angle BDC is 180 - 72 = 108
what are the angles 32 and 114 there for??
5 x (6-3) + 10/ (8-3)
5 x (3) + 10/ (5)
15+2
17
