Step-by-step explanation:
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
Answers
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

Answer:
y = -4x - 11
Step-by-step explanation:
slope intercept form:
y = mx + b
Find y-intercept with slope of -4 and passes through point (-3, 1):
y = mx + b
1 = -4(-3) + b
1 = 12 + b
b = -11 <======== y-intercept
Equation using the given slope of -4 and y-intercept above:
y = mx + b
y = -4x - 11

Using proportions, we have that:
6. From the last pool, 46.43% of voters were for the candidate.
7. Janie makes the triple amount of Jenny.
8. The balance has increased by 3.02% during the year, not 3%.
9. The statement that 10% of the students in the class are men with blond hair is correct.
10. There is a intersection between the percentages of Democrats and of union members, hence we can not affirm that the sets are independent and that 18% of the voters are Democrats who are union members.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
For item 6, we have that:
A 40% increase is represented by 1.4x.The resulting percentage is of 65%.Hence:
1.4x = 65
x = 65/1.4
x = 46.43%.
From the last pool, 46.43% of voters were for the candidate.
For item 7, we have that 200% more than a measure is given by:
x + 2x = 3x.
As the measure by itself is of 100%, hence:
Janie makes the triple amount of Jenny.
For item 8, we have that:
The 1% increase on the first semester is represented by 1.01.The 2% increase on the second semester is represented by 1.02.Hence the yearly increase is given by:
1.01 x 1.02 = 1.0302 = 3.02%.
The balance has increased by 3.02% during the year, not 3%, because the 2% increase on the second semester is over the 1% increase in the first semester, hence the coefficients are multiplied.
For item 9, we have that:
50% of the students are men.Of the men(50%), 20% have blond hair.Hence:
0.2 x 0.5 = 0.1.
The statement that 10% of the students in the class are men with blond hair is correct.
For item 10, we have that:
45% of the voters are Democrats.40% of the voters are union members.There is a intersection between the percentages of Democrats and of union members, hence we can not affirm that the sets are independent and that 18% of the voters are Democrats who are union members.

What is the image point of (7,-5)(7,−5) after a translation right 3 units and down 1 unit?
Answers
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).

Write a linear equation with a rate of change of -5 and initial value at (0, 4)
Answers
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
