In Shadow Bay in July, high tide is at 1:30 pm. The water level is 4 feet at high tide and 0 feet at low tide. Assuming the next

high tide is exactly 12 hours later and the height of the water can be modeled by a cosine curve, find an equation for Shadow Bay's water level in July as a function of time (t).
f(t) = 2 cos pi over 6 t + 1
f(t) = 2 cos pi over 6 t + 2
f(t) = 4 cos pi over 2 t + 1
f(t) = 4 cos pi over 2 t + 2

Holly and Tamar completed the work in the table to determine if a triangle with side lengths of 40, 42, and 58 is a right triang
julia-pushkina [17]

Answer:

B. Tamar is correct.

Step-by-step explanation:

A triangle can be proven as a right angle triangle if  it follows Pythagoras theorem. The pythagoras theorem can be use to know if a triangle is right angled triangle. Therefore, pythagoras theorem is expressed as

c² = a² + b²

where

c = hypotenuse sides

a and b can be any of the opposite or adjacent sides.

The hypotenuse side is the longest side so the triangle with length side of 40, 42 and 58 will have the hypotenuse as 58 . The other sides will be the opposite and adjacent sides

c² = a² + b²

58² = 40 ² + 42²

3364 = 1600 + 1764

3364 = 3364

Therefore, it obeys Pythagoras principle. Tamar's work is correct . The triangle is a right angled triangle.

A local deli sells 4-inch sub sandwiches for $2.95. It has decided to sell a “family sub” that is 50 inches long. How much shoul
lilavasa [31]
You take 50/4 which equals 12.5

so now you say “well one sub is 2.95”
take that and multiply it by 12

12 x 2.95 = 35.4

then you take 2.95 and divide it by 2 that is 1.48

so now you take 35.4 + 1.48

the cost should be 36.88
