Here's is a graph of that function. The 2 is the amplitude of the graph. Meaning the difference from top to bottom is 2, 3-1 is 2
The +1 moves the whole graph up one unit and the minus pi shifts the whole graph left by a length of pi.
Whatever you intended to type before the 'x' . . . " -1.2 " or " - 1/2 " . . .
that's the slope of the line represented by the equation.
A line perpendicular to it has a slope with the negative reciprocal of this one.
So the perpendicular line would be
y = 0.8333 x (negative reciprocal of -1.2) + any number
or
y = 2 x (negative reciprocal of - 1/2) + any number
Answer:
2. 2N
3. -4N
4. 4N
5. 7N
Step-by-step explanation:
7, 13, 19 and 25 have a common difference: 6.
6 added to 7 gives us 13; 6 added to 13 gives us 19, and so on.
Explicit formula: a(n) = 7 + 6(n-1), where 7 is the first term and n is the counter (1, 2, 3, ...).
The first term is 7 (given). This corresponds to n=1.
The second term is a(2) = 7 + 6(2-1), or 7 + 6, or 13. This corresponds to n = 2.
and so on.
Answer:
There are 1084 pupils in that school.
Step-by-step explanation:
If there are 542 girls and boys then you would have to double 542 to get the total number of people. So, there are 1084 people in that school.
Hope this helps!
