1. According to the given graph it is possible to define A - amplitude and B - frequency of this function, then to substitute them to its equation.
2. A=5 (max. and min. values for vertical); B=2 (two periods in the length 2π).
3. answer: y=5sin2x.
Answer:
800 in²
Step-by-step explanation:
Applying,
TSA (A) = Area of the base+ Lateral area of the
A = lw+1/2ps................ Equation 1
Where l = lenght of the base, w = width of the base, p = perimeter of the base, s = slight height of the base.
But,
p = 2(l+w)............. Equation 2
Substitute equation 2 into equation 1
A = lw+1/2[2(l+w)s)
A = lw+s(l+w)............. Equation 3
From the question,
Given: l = 16 in, w = 16 in, s = 17 in
Substitute these values into equation 3
A = (16×16)+17(16+16)
A = 256+544
A = 800 in²
Answer: d) 12 ft
Step-by-step explanation:
Let x be the width of the room , the the length of the room will be 2x.
We consider the shape of room is rectangle.
We know that the area of rectangle is given by :-
, where l is length and w is width.
Given : Area of the room is 288 square feet
Since, width cannot be negative, so the width of the room = 12 feet.

Answer:
In early production, first calcium cyanamide was converted into dicyandiamide, which was heated above its melting temperature to produce melamine. Today most industrial manufacturers use urea in the following reaction to produce melamine: 6 (NH2)2CO → C3H6N6 + 6 NH3 + 3 CO.
