1. The height of the tide in a small beach town is measured along a seawall. Water levels oscillate
between 7 feet at low tide and 15 feet at high tide. On a particular day, low tide occurred at 7:30 AM and
high tide occurred at 1:00 PM.
Write a cosine function of the form f(t) = A cos(Bt) + C, where A, B, and C are real numbers, that
models the water level, o), in feet above or below the average sea level, as a function of the time
measured in 7 hours since 7:30 AM

the area of a triangle is determined by the formula: base x height * 1/2

you'll need to assign a base to the triangle. based on the vertices given, the simplest base would be the line segment from (-2,1) to (2,1). the distance between any two numbers is found by just subtracting them. here, you should subtract the x values to find the distance of this side.

2 - (-2) = 4.

so the distance (aka the length of the base) is 4. the height of the triangle is the distance between the base and the highest point on the triangle which is (3,4). we should subtract the y values this time to find the height/distance.

4 - 1 = 3

so the height is 3.

base = 4

height = 3

hope this if needed hmu

birmudah triangle is scaelenn

c would have to be right.
