Junior is looking into buying a new car he has $2000 for a down payment and he wants to pay $250 per month. for Ford mustang has the following equation for a special deal Y equals 275X +2500 and a dodge charger has a special deal of Y equals 250 X +1500. which deal would work better for him? explain your answer.
Answer:
Step-by-step explanation:
First, we need to calculate the cost of each car after 60 months.
For the Ford Mustang:
Y = 275X + 2500
Y = 275 * 60 + 2500
Y = 16500
For the Dodge Charger:
Y = 250X + 1500
Y = 250 * 60 + 1500
Y = 15000
Next, we can compare the total cost of each car to determine which is the better deal.
In this case, the Dodge Charger is the better deal as it costs $1500 less than the Ford Mustang over the course of 60 months.
It's important to keep in mind that these calculations are based on the assumption that Junior will only make the minimum payments of $250 per month. If he decides to make larger payments or pay off the car early, the total cost of each car will be different.
Additionally, there may be other factors, such as the reliability and maintenance costs of each car, insurance costs, fuel efficiency, and driving experience, that should also be considered before making a decision. Junior should research and weigh all these factors before making a final decision.
In conclusion, the calculation of the cost of each car after 60 months is just one aspect of the decision-making process when buying a car. Junior should consider all relevant factors and weigh the pros and cons of each option before making a final decision.

Write an equation that represents the relationship between the distance the car
has traveled in miles, d, and the amount of gas left in the tank in gallons, x.
Answer: The relationship between the distance a car has traveled in miles, d, and the amount of gas left in the tank in gallons, x, can be represented by the equation:
d = r * m
where r is the fuel efficiency of the car in miles per gallon and m is the amount of gas consumed in gallons.
Since x is the amount of gas left in the tank, we can write:
x = m_0 - m
where m_0 is the initial amount of gas in the tank.
Combining the two equations, we get:
d = r * (m_0 - x)
This equation represents the relationship between the distance the car has traveled in miles, d, and the amount of gas left in the tank in gallons, x.

Can 0 degree and 90 degree form a pair of complementary non adjacent
A 0 degree and 90 degree can form a pair of complementary angles, but 90 degree and an angle that is not adjacent cannot form a pair of complementary angles.
In mathematics, complementary angles are two angles whose sum is 90 degrees. So, if one angle is 0 degrees, the other angle would have to be 90 degrees in order for them to be complementary. However, if one angle is 90 degrees, it cannot form a pair of complementary angles with an angle that is not adjacent (i.e. next to it).
To understand why, consider a straight line, which is equivalent to 180 degrees. If one angle is 90 degrees, it takes up half of the line, leaving the other half for the other angle.
If the other angle is not adjacent, it would have to be placed somewhere on the other half of the line, which is already taken up by the 90 degree angle. Therefore, the two angles cannot add up to 90 degrees and cannot be complementary.

The area of a circle is 49π m². What is the circumference, in meters? Express your answer in terms of
�
π.
Answer: 14π
Step-by-step explanation:
The area of a circle can be expressed as πr^2. In this case, the area is given as 49π m², so we can write:
πr^2 = 49π
Dividing both sides by π, we get:
r^2 = 49
Taking the square root of both sides, we get:
r = 7
The circumference of a circle is given by 2πr, so the circumference in this case would be:
C = 2π * 7 = 14π
So the circumference of the circle with an area of 49π m² is 14π meters.

Why is verifying trig identities so hard?
Verifying trig identities can be difficult because they involve manipulating complex equations with multiple trigonometric functions that have various associated angles and coefficients.
For example, the Pythagorean Identity states that sin2θ + cos2θ = 1, which must be verified by using the identity sin2θ = 2sinθcosθ and substituting it into the equation. This results in a complex equation: 2sinθcosθ + cos2θ = 1, which must then be simplified and rearranged in order to show that it is true for all values of θ. Furthermore, trig identities can involve multiple steps that involve multiple functions and angles, which can make verifying them even more difficult.

Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage rate of increase or decrease.
Answer:
Step-by-step explanation:
y=9700(0.909)^x
# If the base of an exponential function is an element of the set (0,1) the function is decreasing as the value of 'x' is increasing from negative infinity to positive infinity.
the function y=9700(0.909)^x is an exponential function with a coefficient 9700 and base 0.909, as we increase the value of x from negative infinity to positive infinity, the value of y decreases. So the change between two consecutive 'y' values as 'x' increases indicate decay rather than growth.
And it can be written as y=9700(1-0.091)^x, therefore the percentage decrease is 9.1%
