A new car is purchased for 19900 dollars. The value of the car depreciates at 7.5% per year. What will the value of the car br, to the nearest cent, after 8 years?
Answer:
10,665.64
Step-by-step explanation:
Exponential Functions:
y=ab^x
A= starting value = 19900
r=rate = 7.5%=0.075
Exponential Decay:
b=1-r=1-0.075=0.925
Write Exponential Function:
y=19900(0.925)^x
Plug in time for x:
y=19900(0.925)^8
y= 10665.6404317
Evaluate
y≈10665.64

Each of four circles has a radius of 4 inches. A larger circle has an area equal to the total area of the four smaller circles. What is the length of the radius, in inches, of the larger circle?
The radius of the larger circle is 8 inches
What is a circle?A circle is a round plane shape, whose circumference consists of points equidistant from a fixed point.
To calculate the radius of the larger circle, we use the formula below.
Formula:
A = 4A'............. Equation 1Where:
A = Area of the larger circleA' = Area of the smaller circle.But,
A = πR².............. Equation 2A' = πr²........... Equation 3Where:
R = Radius of the larger circler = radius of the smaller circle.Substitute equations 2 and 3 into equation 1
πR² = 4πr²R² = 4r²R = 2r .............. Equation 4Given:
r = 4 inchesSubstitute this value into equation 4
R = 2×4R = 8 inchesHence, The radius of the larger circle is 8 inches.

What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that Members of a lacrosse team raised $1670.50 to go to a tournament.
The rent of the bus is $1013.50.
Now we need to find the left out fund after removing the rent of bus.
so one thousand six hundred and seventy point five minus one thousand and thirteen point five equal to six hundred and fifty seven.
1670.5-1013.5 = $657
The budget for each meal of player is $54.75.
Divide $657 by $54.75. to get the number of players.
657/54.75 = 12.
Hence 12 players the team can bring to the tournament.

What is a probability distribution?For a particular data generation process, a probability distribution represents the predicted outcomes of various values. The mean, standard deviation, skewness, and kurtosis are all features of probability distributions, which are characterized by the mean, standard deviation, skewness, and kurtosis.
The mean of the probability distribution is determined by the given formula,
[tex]\mu = \sum (x\times P(x))[/tex]
Now, substituting the value to know the probability distribution, we will get,
[tex]\mu = (1 \times 0.1)+(2 \times 0.2)+(3 \times 0.4)+(4 \times 0.2)+(5 \times 0.1)\\\\\mu = 0.1+0.4+1.2+0.8+0.5 = 3[/tex]

Solve the following system of equations.
Answer:
x= 0, y= -15
Step-by-step explanation:
Start by labelling the 2 given equations.
y= -2x -15 -----(1)
y= -15 +3x
y= 3x -15 -----(2)
Substitute (1) into (2):
-2x -15= 3x -15
3x +2x= -15 +15
5x= 0
Divide both sides by 5;
x= 0
Substitute x= 0 into (2):
y= 3(0) -15
y= -15
Answer:
Let eqn 1 be y = -2x -15
and Eqn2 be y-3x =-15
Substitute Eqn 1 into Eqn 2
where -2x-15-3x = -15
-5x = 0
X is 0
from Eqn1 the value of y Will be
-2(0) - 15
Value of y is -15
Therefore (X,y) = (0, -15)

Using linear function concepts, it is found that the correct statements are given by:
The value of 15000 represents the start-up cost.The company spends $57,000 to manufacture 2000 headbands.What is a linear function?A linear function is modeled by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and it can also be interpreted as the initial value.In this problem, the cost of manufacturing H headbands is given by:
[tex]C(h) = 21h + 15000[/tex]
The y-intercept is of 15000, which means that the value of 15000 represents the start-up cost.
Manufacturing 2000 headbands, the cost is of:
[tex]C(2000) = 21(2000) + 15000 = 57000[/tex]
