1 point The height of the tide of the ocean is measured along a cliff. The water
level oscillates between 1 foot at low tide and 7feet at high tide. Low tide
occurs at 8 a. m. and high tide is at 2 p. m. at t = 0, the water level is at 1 foot.
Write a function where t is in the number of days. *
-3cos(180t) + 4
-3 sin(180t) + 2
-3cos(90t) + 4
O
-3sin(90t) + 2

the answer to this question is 3/19

step-by-step explanation:

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
