Charles would like to buy a new car that costs $32 000. The dealership offers to finance the car at 2.4%/a, it's best for Charles loans from the bank to buy car.
Which is the best way to buy a car?Generally, the equation for the monthly loan payment is mathematically given as
[tex]R=\frac{\frac{iP}{N}}{1-(\frac{1}{N})^{NY}}[/tex]
Therefore
[tex]R=\frac{\frac{0.024*32000}{12}}{1-(\frac{0.024}{12}+1)^{-12*5}}[/tex]
R=566.51
Hence the total payment is
T=R*N*Y
T=33990.34
By taking a loan of 29000, and applying the equation
T'=33155.77

Write the equation of the circle in general form. Show your work.
Answer:
x^2+2x+y^2−2y−7=0
Step-by-step explanation:
The method from converting to standard to general is very simple
this equation in standard form would be
(x+1)^2+(y-1)^2=9
This is because whatever the center of the circle is, you take the negative/positive version of that number
The center is at -1, 1. So it would flip to be put into the equation as 1, -1.
9 is the radius^2.
The radius is 3.
To convert to general form you just simplify
x^2+1+2x = (x+1)^2
y^2 + 1 -2y = (y-1)^2
x^2 - 2x + y^2 - 2y + 2 = 9
get the nine on the left side
x^2 -2x +y^2 - 2y 2 - 9 = 0
x^2+2x+y^2−2y−7=0

A) Describe the relationship among the lengts of the segments formed by the secant (DB) and secant (CB) . You may use words and/or an equation.
B) Suppose DB = 18 ft, AB = 3 ft, and CB = 10 ft. Find the lengt of CE. Show all your work.
Given the following parameters DB = 18 ft, AB = 3 ft, and CB = 10 ft. Therefore, The length of the CE is 4.6 ft.
What is Secant-secant rule?The secant-secant rule states that if two secants are drawn from an external point to a circle, then the product of the measures of one secant's external part and that entire secant is equal to the product of the measures of the other secant's external part and that entire secant.
Mathematically:
(BA + AD)BA = (BE + EC)BE
Given the following parameters
DB = 18 ft, AB = 3 ft, and CB = 10 ft.
Substitute to check if we can find CE
(BA + AD)BA = (BE + CE)BE
(3+ 15) x 3 = (10 + CE ) x 10
18 x 3 = 100 + 10CE
54 = 100 + 10CE
CE = 4.6
Therefore, The length of the CE is 4.6 ft.

You play a game that requires rolling a six-sided die and then randomly choosing a colored card from a deck containing 3 red cards, 6 blue cards, and 8 yellow cards. Find the probability that you will roll a 5 on the die and then choose a red card.
The probability of getting a red card and rolling a 5 is = 3/85
How to find the probability?First, we want to find the probability of rolling a 5.
There are 6 outcomes on the six-sided die, so the probability of getting a particular value is:
P = 1/5.
Then, the probability of randomly drawing a red card is given by the quotient between the number of red cards and the total number of cards:
P' = 3/(3 + 6 + 8) = 3/17
The joint probability is given by the product between the individual probabilities:
prob = P*P' = (1/5)*(3/17) = 3/85

A drum has a diameter of 20 inches and is 16 inches deep. Find the volume of this drum.
The volume of this drum is approximately
in³.
HELP QUICK!!!!
Answer:
[tex] \boxed{\rm \: Volume_{(Drum)} = 5024 \: in {}^{3} }[/tex]
Step-by-step explanation:
Given :
Diameter of a drum = 20 inchesDeep ( height ) of the drum = 16 inchesπ = 3.14To Find:
The volume of the drum.
Solution:
We all know that drum is cylindrical.So we'll use the formulae of the volume of cylinder,to find its volume.
[tex] \boxed{\rm \: Volume_{(Cylinder)} = \pi{r} {}^{2} h}[/tex]
Where,
r = radiush = height (deep)π = 3.14The value of radius ain't given,but the diameter is given.We can use the formulae of radius.
[tex] \rm \: Radius = D/2[/tex]
D = diameterSubstitute the value of diameter:
[tex] \rm \: Radius = \cfrac{20}{2} = 10[/tex]
Hence,the radius is 10.
So we could now use the formulae of the volume of cylinder:
[tex] \rm \: Volume_{(Cylinder)} = \pi{r} {}^{2} h[/tex]
π = 3.14r =10 inh = 16 in[Firstly bring the answer in terms of π then plug π = 3.14 and then simplify.]
[tex] \rm \: Volume_{(Drum)} = \pi(10) {}^{2} (16)[/tex]
[tex] \rm \: Volume_{(Drum)} =\pi100(16)[/tex]
[tex] \rm \: Volume_{(Drum)} = 1600\pi[/tex]
[tex] \rm \: Volume_{(Drum)} = 1600 \times 3.14[/tex]
[tex] \boxed{\rm \: Volume_{(Cylinder)} = 5024 \: in {}^{3}} [/tex]
Hence, we can conclude that:
The volume of this drum is 5024 in^3.
a car can travel 340 km with 17 litres of petrol. how much can I travel with 20 litres of petrol?
The car would travel a distance of 400 km using 20 litres of petrol
