Answer:
Step-by-step explanation:
The function that could model this periodic phenomenon will be of the form
The tide varies between 3ft and 9ft, which means its amplitude 
is
and its midline 
is
.
Furthermore, since at 
the tide is at its lowest ( 3 feet ), we know that the trigonometric function we must use is 
.
The period of the full cycle is 14 hours, which means
giving us
With all of the values of the variables in place, the function modeling the situation now becomes
Answer:
One piece of fabric: 10 x 6, or 60.
If one triangle is 15, she can cut 4 triangles from each piece of fabric.
If she has 24 pieces of fabric, she can cut 4 x 24, or 96 triangle patches.
Let me know if this helps!
Answer:
yes it is parallel because the alternate interior angles are equal
C^2=a^2+b^2 we are given the hypotenuse of 19 units and one leg of 8 units so:
19^2=8^2+b^2
361=64+b^2
b^2=297
b=√297
b≈17.2 to the nearest tenth
18 buses would depart in an hour.
