The value of a car is decreasing by 12% per year. If the car is worth $11,000 today, what will it be worth in two years?
Answer:
$8518.40
Step-by-step explanation:
FV = PV(1+r)^n
FV = future value
PV = present value
r = rate
n = # of years
Value in 2 yrs = 11,000 x (1 - 0.12)^2 = 8518.4

Answer:
False
Step-by-step explanation:
The terms of a geometric series would have a common ratio. The terms of this series do not. (The differences increase by 1 each time, so it is a quadratic series.)
False, the series is not geometric.
Answer:
Solution :-We are given with the series
6 + 8 + 11 + 15 + 20 + 26
Since
the series is increasing by +1. So, it will be not a geometric series

Lisa scored 85, 92, 87, 93 and 90 on 5 tests. What is the minimum score she needs to make on her 6th test to guarantee a 90 average in math class? The
Answer:
93
Step-by-step explanation:
(85 + 92 + 87 + 93 + 90 + x)/6 = 90

The normal curve shown represents the sampling distribution of a sample mean for sample size n = 25, selected at random from a population with standard deviation \sigma_xσ x . Which of the following is the best estimate of the standard deviation of the population, \sigma_xσ x ?
The best estimate of the standard deviation of the population is 75
How to determine the estimate of the standard deviation of the population?The given parameter is:
Sample size, n
The estimate of the standard deviation of the population is calculated using:
[tex]\sigma_x = \frac{\sigma}{\sqrt n}[/tex]
This gives
[tex]\sigma_x = \frac{\sigma}{\sqrt 25}[/tex]
Evaluate the square root
[tex]\sigma_x = \frac{\sigma}{5}[/tex]
Multiply both sids by 5
[tex]\sigma = 5\sigma_x[/tex]
From the normal curve, we have:
[tex]\sigma_x = 15[/tex] -- the difference between the scores
So,we have:
[tex]\sigma = 5 * 15[/tex]
[tex]\sigma = 75[/tex]
Hence, the estimate of the standard deviation of the population is 75

Answer: first 360 second 1080 third horizontal stretch
Step-by-step explanation:
The period of this parent cosine function [y=cos(x)] is equal to 360 degrees.
What is the period of a cosine function?The period of a cosine function can be defined as the overall length of the interval of values on the x-axis over which a graph lies and it's repeated. Mathematically, the period of this parent cosine function [y=cos(x)] is given by:
T = 2π/A
Where:
A is the coefficient of the x.When A = 1, we have:
T = 2π/1 = 360 degrees.
For the graphed function, the period of this cosine function is given by:
T = 6π
T = 6 × 360

Which of the following is a result of shifting a circle with equation
(x-3)2 + (x - 5)2 = 36
down 2 units?
A. The x-coordinate of the center of the circle decreases by 2.
B. The y-coordinate of the center of the circle decreases by 2.
C. Both the x- and y-coordinates of the center of the circle decrease
by 2.
D. Both the x- and y-coordinates of the center of the circle increase
by 2.
The y-coordinate of the center of the circle decreases by 2. The correct option is B.
What is shifting of the circle?Shifting a circle means moving it to a new coordinate plane location without changing its size or shape.
This can be accomplished by adding or subtracting a constant value from one or both of the circle's centre coordinates.
Shifting a circle is useful in geometry and algebraic problem solving because it allows us to investigate how a circle's position affects its relationship to other shapes and objects on the coordinate plane.
To shift the circle down 2 units, we need to subtract 2 from the y-coordinate of the center. The center of the circle has coordinates (3, 5), so shifting it down 2 units results in a new center at (3, 5 - 2) = (3, 3).
Therefore, the correct answer is B. The y-coordinate of the center of the circle decreases by 2.
