Answer:
$37.85
Step-by-step explanation:
Here the price is $34.98 and there's an 8.2% tax on that. To obtain the after-tax amount due, multiply $34.98 by (1 + 0.082), or 1.082, obtaining:
1.082($34.98) = $37.85 (rounded to the nearest cent)
Answer:
The real perimeter is:

And the area would be:

Step-by-step explanation:
For this case we know one side of a square given 6mm.
We can begin calculating the perimeter for the scale figure with this formula:

The area for this case is given by:

And we know that the drawing has a scale of 1 mm : 7 km and if we convert the perimeter to km we got:

And the area would be:

Answer:
10/6
Step-by-step explanation:
Answer:
Number = 2
Step-by-step explanation:
Let the number be <em>x</em>.
According to the question,
- Number increased by 11 = x+11
- Multiplied by 2 is 26 : (x+11)*2 = 26
Equation will be,
Solving for x,
- 2x+22 = 26
- 2x = 26-22
- 2x = 4
- x = 4/2
- x = 2
Thus,the number is 2.
The functions are:
i)

ii)

.
We note that both Sin and Cos functions cannot produces values smaller than -1, or larger than 1.
In other words, the range of both these functions is [-1, 1].
Whatever expression A is, sin(A) and cos(A) are values in [-1, 1].
Assume

produced its maximal value, 1, then

makes this value 3.
Thus, the maximum value of g(x) is 3, as can be also seen in the graph.
Similarly, assume cos(x) produced 1, then 2cos(x) makes it 2. Thus, the greatest value of f(x) is 2.
Answer: max{f(x)}=2, max{g(x)}=3, so g has the largest maximal value.
