Answer:
"changes the period to pi"
Step-by-step explanation:
f(t) = Sin(t),
Here, t is the period, by definition.
Multiply t by a number that is GREATER THAN 1, makes the period shorter and compressed.
Multiplying t by a number that is between 0 and 1 makes the period expanded.
For the first, if we multiply the period by a, the period becomes 
Since the problem tells us to multiply by 2, we know the period becomes compressed and becomes :

Third answer choice is right.
It is equal because every 2000 pounds is 1 ton and 18000lb divided by 2000 equals 9.
3M^2 + 11MN + 6N^2 = 3M^2 + 2MN + 9MN + 6N^2
= M(3M + 2N) + 3N(3M + 2N) = (3M + 2N)(M + 3N)
Answer: 3M^2 + 11MN + 6N^2 = (3M + 2N)(M + 3N)
Answer:
the answer is 55
Step-by-step explanation:
(28+82)/2
Answer:
141
Step-by-step explanation:
Area of a trapezium =
(a + b)
h = height
a and b = upper and and lower lengths
Area of a trapezium =
(10 + 16)
=
× 26
= 117
Area of a triangle =
× base × height
=
× 6 × 8
=
× 48
= 24
Total area = Sum of the areas of both the shapes
= 117 + 24
= 141
