The period is equal to 2pi/n, where n is the coefficient of t. In this case pi/2. Therefore the period in this example is 4. Frequency is equal to 1/period. Hence the frequency for this problem is 1/4
Gerry folded 3/8 of the pile of shirts. Molly folded 1/8 of the pile of shirts. What is the fraction of shirts they folded all together?
Solve like an equation,
You need x by itself.
Since x is on the denominator, multiply both sides by x to clear the fraction.
Tan 12 = 10/x
x Tan12 = 10
Divide both sides by Tan12
x = 10/(Tan12)
x = 47
A. A square is a special type of parallelogram, so every square is a parallelogram. A. is true.
B. Every parallelogram has two sets of opposite sides parallel, but not all angles are right angles. Only some parallelograms are rectangles, not all. B. is false.
C. A parallelogram with 4 congruent sides is a rhombus. A rhombus is a special type of parallelogram, so every rhombus is a parallelogram. C. is true.
D. A rectangle is a special type of parallelogram, so every rectangle is a parallelogram. D. is true.
