suppose the depth of the tide in a certain harbor can be modeled by y = 20 + 5 cos (pi/6 t), where y is the water depth in feet and t is the time in hours. Consider a day in which t = 0 represents 12:00 midnight. For that day, when are high tide and low tide and what is depth of each
Answer:
- high tide occurs at 12 noon and 12 midnight
- Low tide occurs at 6 a.m and 6 p.m
- maximum depth value = 20 ft
- Minimum depth value = 15 ft
Step-by-step explanation:
The depth is modelled as;
y = 20 + 5 cos (πt/6)
We are told that t = 0 represents 12:00 midnight.
This is high tide because at t = 0, the cos function will be at it's maximum value of 1 since cos 0 = 1.
Max depth value is;
y = 20 + 5(0)
y = 20 ft
Minimum depth value will be the low tide and it will be when the cos function is equal to -1.
Thus;
y = 20 + 5(-1)
y = 15 ft
Since t represents number of hours and since at 12 midnight, t = 0, thus; high tide will occur again at;
12 noon
Also, let's check for low tide.
Let's try t = 6 which means 6 a.m
Thus;
y = 20 + 5 cos (π(6)/6)
y = 20 + 5 cos π
Cos π has a value of -1
Thus;
y = 20 + 5(-1)
y = 20 - 5
y = 15 ft
Thus;
Low tide occurs at 6 a.m and 6 p.m

What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Given the equation y = -2x - 3. Using the table of values:
When x = -1; y = -2(-1) - 3 = 0
When x = 0; y = -2(0) - 3 = -3
When x = 2; y = -2(2) - 3 = -7

Round each number to the specified place value.
81.23 (whole number-ones)
13.567 (tenths)
Answer:
81
13.6
Step-by-step explanation:
When rounding 81.23 to the ones place, look at the following spot, the tenths place, to determine whether to round up or down. If the value is 4 or less, round down. If the value is 5 or greater, round up. 2 is less than 4, so round 81.23 to 81.
Since we're looking to round 13.567 to the nearest tenth, look at the value of the number in the hundreths spot. Repeat the same process as above. 6 is greater than 4, so round 13.567 to 13.6.

Write a linear equation with a rate of change of -5 and initial value at (0, 4)
Answer:
Initial Value: 25, Rate of change -5.
Step-by-step explanation:
First. Lets find the rate of change.
y2-y1/x2-x1 = m
We have A(1,20) B(3,10)
10-20/3-1=-5
m=-5(Rate of change)
Now let's find the initial value using slope-point form.
y-y₁=m(x-x₁)
y-20=-5(x-1)
=-5x+5+20
=-5x+25
The initial value is the value of y when the value of x is equal to 0. (Also the Y-Intercept)
Initial Value = -5(0)+25
=25

What is the image point of (7,-5)(7,−5) after a translation right 3 units and down 1 unit?
Answer:
The translated image point would then be (10, -6) (10, -6)
Step-by-step explanation:
The image point of (7,-5)(7,−5) after a translation right 3 units and down 1 unit is (4,-6)(4,−6)
What is translation?A translation is a type of transformation that takes each point in a figure and slides it the same distance in the same direction.
Now the given points are,
(7,-5)(7,−5)
So, when the image points translates right 3 units there is change in x coordinate. Thus,
(7,-5)(7,−5)
= (7-3,-5) (7-3,−5)
= (4,-5)(4,−5)
and, when the image points translates down 1 unit there is change in y coordinate. Thus,
(4,-5)(4,−5)
= (4,-5-1)(4,−5-1)
= (4,-6)(4,−6)
Thus, the image point of (7,-5)(7,−5) after a translation right 3 units and down 1 unit is (4,-6)(4,−6).

Example 3: The following data was collected by a taxi driver who was interested in how much fuel he used on different journeys. Length of journey 100 250 150 180 220 (miles) 300 Fuel Used (liters) 24 59 44 50 59 97 Estimate how much fuel would be needed for a 200-mile journey.
Answer:
For a 200 mile journey, 55.5 liters of fuel
is needed
Step-by-step explanation:
Here, we want to estimate the fuel needed for a 200 mile journey
we can use this by having an average
By adding all and dividing by 6
Mathematically, that will be;
(24 + 59 + 44 + 50 + 59 + 97)/6
= 55.5
The reason for this is because if we added all the lengths and divide by 6, what we get is 200
Thus, if we added the liters of fuel used per each and divide by 6, we can have an estimate for a 200-mile journey

Find the length of the missing side
Answer:
52
Step-by-step explanation:
To solve, use the Pythagorean Theorem, which says c² = a² + b². Enter 20 as a and 48 as b and square them both. This will give you 400 for a, and 2304 as b. Add them to get 2704. So, c² = 2704. Find the square root of this to get 52. So, the third side is 52 in length.
