A model is made of a car. The car is 10 feet long and the model is 7 inches long. What is the ratio of the length of the car to the length of the model? A. 10 : 7 B. 7 : 120 C. 120 : 7 D. 7 : 10
Final answer:
To find the ratio of the car's length to the model's length, first convert the car's length to inches (120 inches), then compare it to the model's length (7 inches), which gives a ratio of 120 : 7.
Explanation:
The question asks for the ratio of the length of the car to the length of the model. First, it's essential to convert both measurements to the same unit for an accurate comparison. The car is 10 feet long, and since 1 foot equals 12 inches, the car's length in inches is 10 feet × 12 inches/foot = 120 inches. The model is 7 inches long. Therefore, the ratio of the length of the car to the length of the model is 120 inches to 7 inches, which simplifies to 120 : 7.

if you deposit $4000 into an account paying 9% annual interest compounded monthly, how long until there is $10000 in the account?
To determine how long it will take for $4000 to grow to $10000 with an interest rate of 9% compounded monthly, we can use the formula for compound interest and solve for t. The time t is approximately 7.17 years.
Explanation:To find out how long it will take for $4000 to grow to $10000 at an interest rate of 9% compounded monthly, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
Where:
A = total amount after time t
P = principal amount (initial deposit)
r = annual interest rate (as a decimal)
n = number of times interest is compounded per year
t = number of years
By plugging in the given values, we can solve for t:
$10000 = $4000(1 + 0.09/12)^(12t)
Dividing both sides by $4000, we get:
2.5 = (1 + 0.0075)^(12t)
Taking the natural logarithm of both sides, we have:
ln(2.5) = ln(1.0075)^(12t)
Using logarithmic properties, we can isolate t:
12t = ln(2.5) / ln(1.0075)
t = ln(2.5) / (12 * ln(1.0075))
Calculating the value of t, we find that it will take approximately 7.17 years for the account to reach $10000.

A line has slope 2/3 and y–intercept −2.
Which answer is the equation of the line?
(picture is my choices)
The generic form of straight line consisting of slope and y intercept is given by
y = mx + c
Where 'm' is the slope of the straight line and 'c' is the y-intercept
In the problem, it is given that slope of the line is 2/3 and y intercept is -2 :
m = ²/₃
c = -2
By putting these values in the equation above, we get:
y = ²/₃x - 2
Hence, the second option is correct.

We can see that
when it is extrapolated
The curve is going downward
and it is till it touches temperature axis
so, we can find point there
It intersects at temperature =-280C
Since, it is x-intercept
so, y will be 0 at that point
so, Volume will be 0 when temperature is -280C
and this is absolute zero definition of volume function

If the sample size is multiplied by 4, what happens to the standard deviation of the distribution of sample means?
Increasing the sample size by a factor of 4 or multiplying it by 4 is equal to increasing the standard error by 1/2. Therefore, the interval will be half as varied. This also works almost for population averages as lengthy as the multiplier from the t-curve doesn't modify much when increasing the sample size.

The linear function c = 2 y + 29 models the average cost of a haircut in a certain city, where c, is the average price of a haircut y years after 1995. find the slope for the model. then describe what this means in terms of the rate of change in the average cost of a haircut over time
The rate of change implies that the city's haircut prices are consistently going up over time.
The given linear function is c=2y+29, where c represents the average cost of a haircut y years after 1995.
The slope of the linear function, 2, reflects the rate of change in the average cost of a haircut over time.
This means that for each year after 1995, the average cost of a haircut increases by $2. In other words, the slope indicates that the cost of haircuts is rising at a constant rate of $2 per year. This steady increase implies that the city's haircut prices are consistently going up over time.
The positive slope signifies that the average cost is consistently moving upward as the year progresses. Customers can expect to pay, on average, $2 more for a haircut each year compared to the previous year.

How to determine the function is even odd or neither
f(x)=5-3x
if the function is mirrored about the y axis, it is even
use -x in place of x and compare the equations
lets use 2 for x
so given formula would be 5-3(2) = 5-6 = -1
replace x with -x you would have 5-3(-2) =5-(-6) = 5+6 =11
since -1 does not = 11 the function is neither
even =f(x), odd = -f(x), neither f(x) doesn't equal -f(x)
example of odd:
f(x) = x^5 +x, replace x with -x
f(-x) = (-x)^5 +-x
=-x^5-x
=-(x^5+x)
=-f(x)
ODD
Example of even:
f(x) = 1-x^4
f(-x) = 1-(-x)^4
=1-x^4
=f(x)
EVEN
Example of Neither:
f(x) = 2x-x^2
f(-x) = 2(-x)-(-x)^2
=-(2x+x^2)
does not equal f(x)
NEITHER
