a
7
because 4a + 7 - 7
35 - 7
equals 4a
28
and 4a/4
28/4
equals a
7
C. f(x) = – 2 cos 6x + 1
Start by determining the amplitude. Since we've deduced the amplitude is 2, the equation can include either a positive or negative 2 (since amplitude measures absolute value).
Next is the period. The equation for period P is P = (2pi)/b. If P is pi/3, then
pi/3 = (2pi)/b. Thus your b value should be 6.
Finally, the midline would be given by + 1 since adding a unit shifts the function upwards. This means that instead of the highest y value being 2 and the lowest -2, instead you'd have values of 3 and -1.
(3 – 1)/2 = 1 (midpoint theory).
Answer:
A) Leg
Step-by-step explanation:
In a right triangle, the side that is opposite of the right angle is the hypotenuse. It is also the longest side of the triangle.
Since side 'a' makes up a right angle and it's a shorter piece, it is a leg of the triangle.
Hope this helps.
