Answer:
Value of the car after depreciation = $800.
Step-by-step explanation:
Formula to get the final value of the car after depreciation of the car price,
Final value = [tex]\text{Initial value}(1-\frac{r}{100})^{\frac{t}{n} }[/tex]
Here, t = Number of years after the purchase
n = Number of years for the depreciation of price by half
By substituting values in the formula,
Final value = [tex]40000(1-\frac{50}{100})^{\frac{17}{3}}[/tex]
= [tex]40000(0.5)^{\frac{17}{3}}[/tex]
= $787.451
≈ $800 [Nearest hundred dollars]
Therefore, after 17 years value of the new car will be $800.

Step-by-step explanation:
y = x² +1,x>0
find the inverse
Answer:
The inverse of x² +1 is:
[tex]\sqrt{x-1},\:-\sqrt{x-1}[/tex]
Step-by-step explanation:
Given
y = x² + 1, x>0
We know that A function g is the inverse of a function f if for y = f(x), x = g(y)
y = x² +1
Replace x with y
x = y² + 1
solve for y
y² = x - 1
Taking square root
[tex]y=\:\sqrt{x-1},-\sqrt{x-1}[/tex]
Thus, the inverse of x² +1 is:
[tex]\sqrt{x-1},\:-\sqrt{x-1}[/tex]

Answer:
The first option (the uppermost) is correct.
Step-by-step explanation:
When you multiply 1/2 by 3/4, you obtain the result of (1x3) / (2x4).
Simplifying, this gives us the result: 3/8, which is represented by the first choice.

2,000 - 61k = 48
In 1962, the population of a bird species was 2,000.
The population k years after 1962 was 48, and k
satisfies the equation above. Which of the following
is the best interpretation of the number 61 in this
context?
Answer:
61 is the rate at which the population changes every year
Step-by-step explanation:
Given
[tex]2000 - 61k = 48[/tex]
Required
Interpret 61
A linear equation has the form:
[tex]y = mk + b[/tex]
or
[tex]b + mk = y[/tex]
Where m is the rate
By comparison:
[tex]mk = -61k[/tex]
[tex]m = -61[/tex]
Hence, 61 represents the rate at which the population changes yearly.
The negative sign implies that the populatiin reduces
I NEED MEGA HELP WITH THIS QUESTION
Answer:
C. [tex]y = - \frac{1}{4} x - 2[/tex]
Step-by-step explanation:
To find slope using coordinates, use the formula above.
[tex](4, - 3) \: (0, - 2)→ \frac{ - 2 - ( - 3)}{0 - 4}→ \frac{ - 2 + 3}{ - 4} → - \frac{1}{4} [/tex]
Now, using the [tex]y = mx + b[/tex] formula, plug in [tex] - \frac{1}{4} [/tex] as [tex]m[/tex] (slope) and either coordinate as the [tex]x[/tex] and [tex]y[/tex] values. It looks like this:
[tex] - 3 = - \frac{1}{4}(4) + b[/tex]
To solve for [tex]b[/tex], continue to use PEMDAS.
[tex] - 3 = - \frac{1}{4}(4) + b→ - 3 = - 1 + b→ - 2 = b[/tex]
Now use [tex]m[/tex] and [tex]b[/tex] to solve for your equation:
[tex]y = - \frac{1}{4} x - 2[/tex]
The answer is C.

The sales tax for an item was $9.80 and it cost $490 before tax. Find the sales tax rate. Write your answer as a percentage.
Answer:
2%
Step-by-step explanation:
To solve this problem, a proportion would be best! We can set up the first fraction with the two numbers given to us. We'll use t to represent tax, and w to represent the whole. The first fraction will look something like this:
[tex]\frac{9.80t}{490w}[/tex]
Next, we'll set up our second fraction using knowledge of percents. Every percent is a part of 100%, so we can use 100 as our percent to represent the whole. Since we are solving for the percent that is out of 100, we'll use x to represent it. The final proportion should look like this:
[tex]\frac{9.80t}{490w} = \frac{x}{100w}[/tex]
To solve, we just need to cross-multiply and divide! First, multiply 9.80 by 100 to get 980. Finally, divide 980 by 490 to get a final answer of 2%. The sales tax rate is 2%. The final calculations are as follows:
9.80 X 100 = 980
980 / 490 = 2 or 2%
Im struggling in math rn and i need help with this problem 3 1/4 = 1/2 + w
Answer:
w= 2 3/4
Step-by-step explanation:
First, we need to find what can equal w. So, we can subtract 1/2 form both sides, so one sides has just w and one side has just a number. 3 1/4-1/2= 2 3/4. So w= 2 3/4
Answer:
2 3/4
Step-by-step explanation:
3 1/4 = 1/2 + w
Transfer 1/2 to other side
3 1/4 - 1/2 = w
Solve
w = 2 3/4

write the equation of the line given the y- and x- intercepts
y intercept (-6,0), x-intercept (0,-8)
y intercept (0,-6), x-intercept (-2,0)
y intercept (0,8), x-intercept (1.6,0)
y intercept (0,7), x-intercept (-1.4,0)
Answer:
y intercept (-6,0), x-intercept (0,-8) : [tex]y = \frac{-4}{3}x -8[/tex]
y intercept (0,-6), x-intercept (-2,0): [tex]y = -3x -6[/tex]
y intercept (0,8), x-intercept (1.6,0): [tex]y = -5x + 8[/tex]
y intercept (0,7), x-intercept (-1.4,0): [tex]y = 5x + 7[/tex]
Step-by-step explanation:
y = mx + b
*note: b is the y intercept
1. y intercept (-6,0), x-intercept (0,-8)
[tex]m = \frac{-8 - 0}{0 - (-6)}= \frac{-8}{6} = \frac{-4}{3}\\y = \frac{-4}{3}x + b\\y = \frac{-4}{3}x -8[/tex]
2.y intercept (0,-6), x-intercept (-2,0)
[tex]m = \frac{0 - (-6)}{-2 - 0} = \frac{6}{-2} = -3\\y = -3x + b \\y = -3x -6[/tex]
3. y intercept (0,8), x-intercept (1.6,0)
[tex]m = \frac{0 - 8}{1.6 - 0}= \frac{-8}{1.6} = -5\\y = -5x + b\\y = -5x + 8[/tex]
4. y intercept (0,7), x-intercept (-1.4,0)
[tex]m = \frac{0 - 7}{-1.4 - 0} = \frac{-7}{-1.4}= 5 \\y = 5x + b\\y = 5x + 7[/tex]
