Answer:
$14,030.48
Step-by-step explanation:
We can use the following formula to solve:
[tex]A=P(1-r)^t[/tex]
P = principal value
r = rate (decimal)
t = time (years)
First, lets change 7.3% into a decimal:
7.3% -> [tex]\frac{7.3}{100}[/tex] -> 0.073
Next, plug in the values:
[tex]A=19,000(1-0.073)^4[/tex]
[tex]A=14,030.48[/tex]
The value will be $14,030.48

Name at least one way that the ocean impacts each of Earth’s four major systems. How does the ocean keep west coast cities cool during the summer?
Answer:
The ocean influences weather and climate by storing solar radiation, distributing heat and moisture around the globe, and driving weather systems.
One way that the world’s ocean affects weather and climate is by playing an important role in keeping our planet warm. The majority of radiation from the sun is absorbed by the ocean, particularly in tropical waters around the equator, where the ocean acts like a massive, heat-retaining solar panel. Land areas also absorb some sunlight, and the atmosphere helps to retain heat that would otherwise quickly radiate into space after sunset.
The ocean doesn't just store solar radiation; it also helps to distribute heat around the globe. When water molecules are heated, they exchange freely with the air in a process called evaporation. Ocean water is constantly evaporating, increasing the temperature and humidity of the surrounding air to form rain and storms that are then carried by trade winds. In fact, almost all rain that falls on land starts off in the ocean. The tropics are particularly rainy because heat absorption, and thus ocean evaporation, is highest in this area.
Outside of Earth’s equatorial areas, weather patterns are driven largely by ocean currents. Currents are movements of ocean water in a continuous flow, created largely by surface winds but also partly by temperature and salinity gradients, Earth’s rotation, and tides. Major current systems typically flow clockwise in the northern hemisphere and counterclockwise in the southern hemisphere, in circular patterns that often trace the coastlines.
Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth’s surface. Without currents in the ocean, regional temperatures would be more extreme—super hot at the equator and frigid toward the poles—and much less of Earth’s land would be habitable.

The ocean impacts Earth's four major systems in several ways. Here are some examples:
How ocean impacts the earth?Geosphere: The ocean is closely connected to the geosphere, as it plays a significant role in shaping the Earth's surface. Waves and currents erode coastlines and move sediment around, while underwater volcanic activity can create new landmasses and alter ocean chemistry.
Atmosphere: The ocean is an important component of the Earth's climate system, with ocean currents and temperatures influencing weather patterns and regulating the Earth's temperature. The ocean also absorbs carbon dioxide from the atmosphere, which helps to mitigate the effects of climate change.
Biosphere: The ocean supports a vast array of life, from microscopic plankton to massive whales. Marine ecosystems are interconnected with terrestrial ecosystems, with many species relying on the ocean for food and habitat.
Hydrosphere: The ocean is the largest component of the Earth's hydrosphere, and plays a critical role in the water cycle. Ocean currents and evaporation drive the movement of water around the planet, while the ocean stores vast amounts of water that can be released into the atmosphere through evaporation.
As for how the ocean keeps west coast cities cool during the summer, this is due to a phenomenon called coastal upwelling. As warm air rises over the land, it creates a low-pressure zone that draws in cool, moist air from the ocean.
This cool air can then be pushed inland by the sea breeze, providing relief from the summer heat. Additionally, the cold water that is brought to the surface during upwelling helps to cool the air near the coast.

Question 1: The water level in a tank can be modeled by the function h(t)=4cos(+)+10, where t is the number of hours
since the water level is at its maximum height, h. How many hours pass between two consecutive times when
the water in the tank is at its maximum height?

Question 2: Point B has coordinates (3, -4) and lies on the circle whose equation is x + y = 25. If an angle is drawn in
standard position with its terminal ray extending through point B, what is the sine of the angle?
Your answer...
Answer:
Question 1: The hours that will pass between two consecutive times, when the water is at its maximum height is π hours
Question 2: Sin of the angle is -0.8
Step-by-step explanation:
Question 1: Here we have h(t) = 4·cos(t) + 10
The maximum water level can be found by differentiating h(t) and equating the result to zero as follows;
[tex]\frac{\mathrm{d} h(t)}{\mathrm{d} t} = \frac{\mathrm{d} \left (4cos(t) + 10 \right )}{\mathrm{d} t} = 0[/tex]
[tex]\frac{\mathrm{d} h(t)}{\mathrm{d} t} = - 4 \times sin(t) = 0[/tex]
∴ sin(t) = 0
t = 0, π, 2π
Therefore, the hours that will pass between two consecutive times, when the water is at its maximum height = π hours.
Question 2:
B = (3, -4)
Equation of circle = x² + y² = 25
Here we have
Distance moved along x coordinate = 3
Distance moved along y coordinate = -4
Therefore, we have;
[tex]Tan \theta = \frac{Distance \ moved \ along \ y \ coordinate}{Distance \ moved \ along \ x \ coordinate} = \frac{-4}{3}[/tex]
[tex]\therefore \theta = Tan^{-1}(\frac{-4}{3}) = -53.13^{\circ}[/tex]
Sinθ = sin(-53.13) = -0.799≈ -0.8.

What expression is equivalent to x^6-9
Answer:
x^6-9 = x^-3 = 1/x^2
Step-by-step explanation:
Hi! I'm happy to help!
To solve this, we need to simplify this expression as much as possible. We see that in the exponent, we have the expression 6-9, which we can substitute for -3.
[tex]x^{6-9}[/tex]
[tex]x^{-3}[/tex]
To further simplify, we need to find out what [tex]x^{-3}[/tex] is. Whenever using a negative exponent, follow this equation.
[tex]x^{-y}[/tex]=[tex]\frac{1}{x^{y} }[/tex]
Using this, we can turn [tex]x^{-3}[/tex], into [tex]\frac{1}{x^{3}}[/tex]. Since we do no know what x is, we cannot simplify any further.

Two negative integers are 5 units apart on the number line, and their product is 126. What is the sum of the two integers?
–23
–5
9
14
Answer:
-23
Step-by-step explanation:
-23 is the answer
The sum of the two integers if they are 5 units apart on the number line, and their product is 126 is -23
System of equationsSystem of equations are equations that contain unknown variables with more than 1 equation.
Let the required integers be x and y.
If two negative integers are 5 units apart on the number line, then;
x - y = 5
x = 5 + y
If their product is 126, hence:
x y = 126
Substitute
5+y(y) = 126
5y + y^2 = 126
y^2 + 5y - 126 = 0
Factorize
y^2 + 14y - 9y - 126 = 0
y(y + 14) - 9(y + 14) = 0
y = 9 and - 14
Since the integers are negative, hence;
x = 5 + y
x = 5 - 14
x = -9
Sum = -14 + (-9)
sum = -23
Hence the sum of the two integers is -23

When a force of 30 N acts on a certain object the acceleration of the object is 5m/s2 if the force is changed to 54 N what will be the acceleration of the object
Answer:
The correct answer is 9 m per [tex]second^{2}[/tex]
Step-by-step explanation:
Force is defined by mass of an object times it's acceleration.
Let the mass of the object be m kilograms.
When a force of 30 N acts on a certain object the acceleration of the object is 5 m per [tex]second^{2}[/tex]
∴ 30 = m × 5
⇒ m = 6.
If the force is changed to 54 N, let the acceleration of the object be x m per [tex]second^{2}[/tex].
∴ 54 = m × x
⇒ x = [tex]\frac{54}{6}[/tex] = 9
Thus when the force is 54 N, the acceleration of the object is 9 m per [tex]second^{2}[/tex].

What does 9(3-2x)=2(10-8x) equal to
Answer:
x=72 x = 7 2
Step-by-step explanation:
Answer:
x=7/2
Step-by-step explanation:
First, distribute the 9 on the left side
9(3-2x)=2(10-8x)
(9*3)+(9*-2x)= 2(10-8x)
27-18x= 2(10-8x)
Next, distribute the 2 on the right side
27-18x=(2*10)+(2*-8x)
27-18x=20-16x
Now, move all the numbers to one side of the equation, and the variables to the other.
27-18x=20-16x
Add 18x to both sides
27-18x+18x=20-16x+18x
27=20+2x
Subtract 20 from both sides
27-20=20-20+2x
7=2x
Now all the variables are on one side, and the numbers are on the other. x is still not by itself. It is being multiplied by 2. To undo this, divide both sides by 2
7/2=2x/2
7/2=x

7-11 mini-mart started a promotion where you can buy a refillable 40 oz. Soda for a one-time price $6.00, then fill the cup for $0.79 per year for a year or you can buy their filled disposable 32 oz. Soda cup for $1.69. How many sodas do you need to buy to make it work buying the refillable cup?
Answer:
7 cups of soda
Step-by-step explanation:
If we call the number of cups you buy by "x", we have that the price for the refillable cup P1 is:
P1 = 6 + 0.79*x
And the price for the other option is:
P2 = 1.69*x
To find how many sodas do you need to buy to make it work buying the refillable cup, you just need to equate the two prices and find the value of x:
P1 = P2
6 + 0.79*x = 1.69*x
0.9*x = 6
x = 6/0.9 = 6.6667 cups
So, you need to buy at least 7 cups of soda to make the refillable cup worth it.

A band sold out a concert with 4,200 seats. A random sample of 120 ticket buyers is surveyed, and 28 buyers made their purchase on the first day tickets were being sold. How many of the 4,200 tickets are likely to have been purchased on the first day?
Answer: 980 tickets
Step-by-step explanation:
A band sold out a concert that has 4,200 seats. A random sample of 120 ticket buyers was surveyed, and 28 buyers were found to have made their purchase on the first day the tickets were being sold. This means (28/120) = 7/30 of the 120 ticket were purchased on the first day.
To get the number of first day tickets purchased when 4,200 tickets are likely to have been purchased will be the fraction gotten multiplied by 4200. This will be:
= 7/30 × 4200
= 29400/30
= 980 tickets
