The expression of an exponential function f that has a slope of 12 of a line from the point (0, f(0)) to the point (2, f(2)) is the exponential function;
f(x) = 3·3ˣWhat is an exponential function?An exponential function is a function that includes the argument as an exponent, index or power of a constant.
The points on the function are; (0, f(0)), and (2, f(2))
The required slope between the points x = 0, and x = 2 is 12
Therefore;
(f(2) - f(0))/(2 - 0) = 12
f(2) - f(0) = 12 × (2 - 0) = 24
The
The exponential function can be presented in the form; f(x) = a·bˣ
When x = 0, we get; f(0) = a·b⁰ = a
When x = 2, we get; f(2) = a·b²
f(2) - f(0) = a·b² - a = 24
a·(b² - 1) = 24
Let a = 3, and b = 3, we get;
3 × (3² - 1) = 24
Therefore, possible values of a and b are; a = 3, and b = 3
The exponential function is therefore;
f(x) = 3 × 3ˣThe slope of the line that extends from the point (0, f(0)), to the point (2, f(2), is therefore;
(f(2) - f(0))/(2 - 0) = (3 × 3² - 3 × 3⁰)/(2 - 0) = 12Learn more on exponential functions here: https://brainly.com/question/15662160

What is median of a triangle Class 7?
A triangle's median is a straight path that joins a vertices to the midpoint of the following sectors across from it.
A triangle is a three-sided polygon that consists of three vertices, three sides, and three angles. Three types of triangles—scalene, isosceles, and equilateral—can be distinguished based on the length of their sides.
It can be an acute-angled, obtuse-angled, or right-angled triangle depending on the size of its angles. A triangle's internal angles add up to 180 degrees. Two more terms—altitude and triangle median—are introduced to you in this essay.

If UY= 3x - 6 and YV = x + 2, find UV.
(WY INTERSECTS UV AT Y)
WY intersects UV at Y and hence the value of UV is 8.
What is point of intersection?They are referred to be intersecting lines when two or more lines in a plane cross each other. The point of intersection, which can be found on all intersecting lines, is the common point shared by the intersecting lines.
Given that WY intersects UV at Y.
Hence, the value of UY = YV.
Substitute the value of UY and YV as follows:
UY = YV
3x- 6 = x + 2
3x - x = 2 + 6
2x = 8
x= 2
Now, the value of UV = UY + YV
Substitute the values:
UV = UY + YV
UV = 3x - 6 + x + 2
UV = 4x - 4
Substitute the value of x as follows:
UV = (4)(2) - 4

How many years will it take for an investment to double if the rate is 6.75% and it is compounded monthly?
By solving an exponential equation, we can see that the investment will be doubled after 10.6 years.
How many years will it take for the investment to double?The investment can be modeled by the exponential equation:
P(x) = A*(1 + 6.75%/100%)^x
Where A is the initial value of the investment (the amount invested).
We can simplify this to get:
P(x) = A*(1 + 0.0675)^x
The investment will be doubled when:
2*A = A*(1 + 0.0675)^x
We want to solve this for x.
2 = (1 + 0.0675)^x
2 = (1.0675)^x
If we apply the natural logarithm in both sides:
ln(2) = ln((1.0675)^x)
ln(2) = x*ln(1.0675)
ln(2)/ln(1.0675) = x
10.6 = x

b. Write an equation for the cost of the more expensive brand.
c. What is the cost of running the cheaper unit for 36 months?
d. For how many months will the cost of both brands be equal?
An equation for the cost of the cheaper brand is y = 60x + 1,800.
An equation for the cost of the more expensive brand is y = 50x + 2,600.
The cost of running the cheaper unit for 36 months is $3,960.
The number of months for which the cost of both brands would be equal is 8 months.
How to write an equation to model this situation?In order to write an equation that model this situation, we would assign variables to the time and cost respectively, and then translate the word problem into algebraic equation as follows:
Let the variable x represent the time measured in months.Let the variable y represent the cost measured in dollars.Since a brand cost $1800 to buy with a monthly operation fee of $60, an equation for the cost of this cheaper brand is given by:
y = 60x + 1,800.
When x = 36 months, the cost of running the cheaper unit is given by:
y = 60(36) + 1,800.
y = $3,960.
For the more expensive brand, we have:
y = 50x + 2,600.
Next, we would determine the number of months for which the cost of both brands would be equal;
50x + 2,600 = 60x + 1,800
60x - 50x = 2,600 - 1,800
10x = 800
x = 800/10
x = 8 months.

Volume is the measure of the amount of space occupied by an object or substance. It is often represented by the symbol 'V' and is typically measured in units such as liters (L), cubic meters (m^3), or gallons (gal). In three-dimensional space, the volume of an object is calculated by multiplying its length, width, and height (or depth). In two-dimensional space, the area of an object can be calculated by multiplying its length and width.
The volume of the metal bar is 3 cm x 3 cm x 2 cm = 18 [tex]cm^3[/tex]. The density of water is 1 g/[tex]cm^3[/tex]. To find the volume of water displaced, we need to convert the volume of the bar from cubic centimeters to liters.

charges $50.50 and 9¢ per mile. How much more does Company A charge for x miles than Company B?
Company A charges $5.00 and 6 cents much more for x miles than Company B. The solution is obtained using arithmetic operations.
What are arithmetic operations?There are four basic operations which are listed as follows: Addition(‘+’): This operation deals with finding the sum. Subtraction(‘-’): This operation deals with finding the difference. Multiplication(‘×’): This operation deals with finding the product. Division(‘÷’): This operation deals with finding the quotient.
In order to find how much more does company A charge than company B, we need to subtract the charges of company B from that of Company A.
So, on subtracting we get,
$55.50 and 15 cents - $50.50 and 9 cents = $5.00 and 6 cents per mile.
For x miles, we multiply $5.00 and 6 cents by x miles.
Also, we could convert dollars to cents by multiplying it by 100.
as $1 =100 cents.
5565 - 5059 cents = 506 cents.

Micah paint birdhoue to ell at a fair. The table how the amount of paint he ue. I thi a proportional relationhip? If o, find the contant of proportionality and write an equation for the relationhip
The constant of proportionality is 12. The equation to represent the relationship is : b = 12p.
Constant proportional:
A constant of proportionality is a constant value for the ratio of two proportional quantities. If the ratio or product is constant, the two variables are proportional. The value of the constant of proportionality depends on the type of relationship between the two given quantities (positive versus inverse variation).
According to the question:
From the above mentioned , the individual ratio of number of birdhouse (b) cans of paints is:
Now,
For 1st pair,
b/ p = 3/ 1/4
⇒ b / p = 3 ×4 /1
⇒ b/ p = 12
Again,
For 2nd pair,
b /p = 9/0.75
⇒ b /p = 12
For 3rd pair,
b /p = 18/3/2
⇒ b /p = 18× 2/3
⇒ b/ p = 12
Finally,
For 4th Pair =
⇒ b/ p = 20/2.5
⇒ b/ p = 12
As all the ratios are equivalent, the relationship between number of birdhouse (b) and cans of paints (p) is proportional. The constant of proportionality is 12. The equation to represent the relationship is :
b = 12p.
