Standard Equation for trig function: y = A cos (B (x - H))+ K
*Here, we are just dealing with A (amplitude) and B (period)
Period = 2π/ b
8 = 2π/ b
Solve for b: 2π/8 or π/4
Equation: y = 2 cos (π/4 (x))
First, set the coordinate points on a graph, and joint them to form a graph
By looking at the graph we can see that:
width : 3
length: 6
Area of a rectangle : Length x width : 6 x 3 = 18
Answer:
9, -3
Step-by-step explanation:
Divide the long leg by the square root of 3 to find the short leg. Double that figure to find the hypotenuse.
$55-$35=20
$20 divide by $0.25=80 miles.
therefore denise can drive the car for 1day 80 miles to stay within her budget
