Answer:
(B) y=2x^2
Step-by-step explanation:
(1/2) and (1/4) make the graph wider
2 makes it narrower
Answer:
no solutions
Step-by-step explanation:
−2a + 2a + 7 = 8
Combine like terms
7 = 8
This is never true so there are no solutions
Answer:
Step-by-step explanation:
Subset of A = { {} , {a} , {b}, {a.b} }
Answer: 4 1/6 = 6/25
5 5/6 = 6/35
1 5/6= 6/11
Step-by-step explanation:
Answer:
∠Q = 53.13 degrees
Step-by-step explanation:
Given that ∆PQR, ∠P = 90degrees , this means that the triangle is a right angled triangle
Hence using the notation
SOH CAH TOA
where S is sine, C is cosine, T is tangent and O, A and H represents the size of the opposite, adjacent and hypotenuse sides
Considering ∠Q and the given sides
PR=16cm is the opposite side,
PQ= 12 cm is the adjacent side hence we use TOA
Tan Q = 16/12 =
Q = Arc tan 16/12
= 53.13 degrees
