An exponential function that best represents the value of the computer in months is V(t) = 1500(0.9763)^m.
What is an exponential function?In Mathematics, an exponential function simply refers to a mathematical function whose values are generated by a constant that is raised to the power of the argument. Mathematically, an exponential function can be modeled by using this equation:
f(x) = ab^t
Where:
a represents the initial value.t represents time.b represents the rate of change.From the information provided, the value, V, of a computer is modeled by this function:
V(t) = 1500(0.75)^t
Where:
t represents the number of years since the computer was purchased.
Note: one (1) year is equal to 12 months (m).
Now, we can remodel the value of this computer in months:
V(t) = 1500(0.75)^m/t
V(t) = 1500(0.75)^m/12
V(t) = 1500(0.75^{1/12})^m
V(t) = 1500(0.9763)^m

The inverse function of f(x) = 3x-4 when x = -1 will be 1.
According to the question,
We have the following function:
f(x) = 3x-4
Now, to find its inverse we will convert this function into a linear equation:
y = 3x-4
Now, we will change variable from x to y and y to x:
x = 3y-4
Now, we have to find the value of y, which will be the inverse of the given function:
Moving 4 from the right hand side to the left hand side will result in the change of signs:
x+4 = 3y
3y = x+4
Dividing by 3 on both the sides:
y = (x+4)/3
Now, we have:
[tex]f^{-1} (x)[/tex] = (x+4)/3
Putting the value of x = -1:
(-1+4)/3
3/3
1
Hence, the inverse function of f(x) = 3x-4 when x = -1 will be 1.

In a farm composed of cows and chickens, there are total of 13 heads and 42 feet. How many cows are there?.
In a farm composed of cows and chickens, there are total of 13 heads and 42 feet.
Let 'h’ represent the number of hens the farmer has.
Let 'c’ represent the number of cows the farmer has.
Assume that all hens have two legs and all cows have four.
There are a total of 42 legs. So
2h + 4c = 42 (1)
There are 13 animals in total.
h + c = 13 (2)
Now that we have our system of equations, we can solve by either substitution or elimination.

What is the image of (-1,-1) after a dilation by a scale factor of 5 centered at the origin
Answer:
If the plot point was dilated by a scale factor, it would be multiplying the scale factor with each X and Y. Therefore it would be (-5,-5)
The image of (-1, -1) after the dilation by a scale factor of 5 centered at the origin is (-5, -5).
To find the image of (-1, -1) after a dilation by a scale factor of 5 centered at the origin, we can apply the formula for dilation in the coordinate plane.
The formula for dilation with a scale factor of k centered at the origin is (k * x, k * y), where (x, y) is the original point.
In this case, the original point is (-1, -1), and the scale factor is 5. Applying the dilation formula, we have:
Image = (5 * (-1), 5 * (-1))
= (-5, -5)
This means that the point (-1, -1) is dilated by a factor of 5, and its position is shifted five times farther from the origin in both the x and y directions.

The amount of money left with Alizay after shopping is Rs 17700 .
Alizay sold shirts for Rs. 2800.
She sold 14 shirts.
Cost earned from selling 14 shirts = 14 × 2800 = Rs. 39200
Spent on shopping =Rs. 14000
Spent on Grocery = Rs. 7500
Total amount spent = Rs.(14000+7500) = Rs. 21500
Amount of money left = Rs 39200 - Rs 21500 = Rs 17700

The volume V of a sphere varies in direct proportion to the cube of its radius .
What change in volume reduces the radius by 10% ?
There will be no change in volume reducing the radius by 10%.
What is Direct Proportion?
The relationship between two values where their ratio equals a constant number is known as a direct proportion or direct variation. Since the other variable is reversed in this case, the inversely proportional relationship is really represented by the same symbol.
For instance, if x and y are two quantities or variables that are intimately linked to one another, we can say x y. The ratio of x and y becomes equal to a constant when the proportionality sign is removed, for example, x/y = C, where C is a constant. In contrast, x and y are represented as x 1/y or xy = C in the case of inverse proportion.
Let the radius be r then
The volume of every sphere is,
[tex]\mathrm{V}=4 \pi \frac{\mathrm{r}^3}{3}[/tex]
In the given question, It is given:
The volume V of a sphere varies in direct proportion to the cube of its radius.
That means:[tex]\mathrm{V}[/tex] ∝ [tex]r^{3}[/tex]
That means:[tex]4 \pi \frac{\mathrm{r}^3}{3} = kr^{3}[/tex]⇒[tex]4 \pi \frac{\mathrm{1}}{3} = k[/tex]

3x + 5y = 5
Y = -x -2
Find ( x , y )
As per the substitution method, the value of (x , y) is (-15/2, 11/2)
Substitution method:
Substitution method is the process of solve one equation for one of the variables. And substitute (plug-in) this expression into the other equation and solve. Then resubstitute the value into the original equation to find the corresponding variable.
Given,
Here we have the following expression.
3x + 5y = 5
Y = -x -2
Now, we need to find the value of x and y.
According to the substitution method, let us consider
3x + 5y = 5 -------------------(1)
Y = -x -2 ---------------------(2)
Now, we have to apply the value of y as -x - 2 in equation (1), then we get,
=> 3x + 5(-x - 2) = 5
When we expand it then we get,
=> 3x - 5x - 10 = 5
Simplify the expression,
=> -2x - 10 = 5
=> -2x = 5 + 10
=> -2x = 15
Then the value of x is,
=> x = -15/2
If the value of x is -15/2. then the value of y is calculated by using the equation (2),
=> y = -(-15/2) - 2
=> y = 15/2 - 2
=> y = (15 - 4)/2
=> y = 11/2
Therefore, the value of (x, y) is (-15/2, 11/2).

To find the slope divide the rise by the run. The rise would be the difference between the 2 y points (y2-y1) divided by the run (x2-1x)
Here the rise is (-9-3 = -12) and the run is (8-(-1) = 9) So -12/9 is -4/3 in fraction form and -1.33 in decimal form.

#Sam want to enlarge a triangle with side lengths 3, 6, and 9 inches. If the shortest side of the new triangle is 12 inches, what is the perimeter of the new triangle?
Answer: 72 in
Step-by-step explanation:
The shortest side length of the original triangle was 3in, and the newer one is now 12in. From 3in to 12in, you use a scale factor of 4. Hence, we multiply each side length of the original triangle by 4. And to find the perimeter of the new triangle, you add all the sides up.
3(4) + 6(4) + 9(4) = 72 in
what is the smallest possible perimeter, in units, of a triangle whose side-length measures are consecutive integer values?
If a triangle whose sides length measures are consecutive integers, then the smallest possible perimeter is 9 units
If a, b and c are the sides of the triangle
Then it will be
a + b > c
b + c > a
c + a > b
Given that the side length of the measures are consecutive integer
Smallest consecutive integer is 1, 2 and 3
But
1 +2 > 3
3 = 3
Therefore it will not be the sides of the triangle
Next smallest consecutive integers are 2, 3 and 4
Then,
2+3 > 4
5 > 4
3+4 > 2
7 > 2
2+4 > 3
6 > 3
This will be the sides of the triangle
The perimeter of the triangle is the sum of sides of the triangle
The perimeter = 2 + 3 + 4
