the predicted biomass for the year 2020 is 41,666 kg.
What is exponential?
The exponential is an example of a mathematical function that is useful in determining if something is increasing or decreasing exponentially is the exponential function. As implied by its name, an exponential function uses exponents. But take note that an exponential function does not have a variable as its exponent and a constant as its base (if a function has a variable as the base and a constant as the exponent then it is a power function but not an exponential function).
The growth rate function's units on it (along with 4t and dt) are years, therefore year = kg year will result in an integral that will show the net change in kilogrammes from 2000 to 2020.
if the biomass was 25,000 kg in the year 2000, what is the predicted biomass for the year 2020.
WE GET: 60000(-1/3) ∫(1/u)
=16666
This is the change in biomass from 2000 to 2020. Thus, the predicted biomass for 2020 is about (25000 + 16,666) = 41,666 kg.
Hence, the predicted biomass for the year 2020 is 41,666 kg.

The ratio of Marta’s hourly pay to Khalid’s hourly pay is 6 : 5
Both Marta and Khalid get an increase of £1.50 in their hourly pay.
The ratio of Marta’s hourly pay to Khalid’s hourly pay after this increase is 13 : 11
Work out the hourly pay before the increase for Marta and for Khalid
The hourly pay before the increase for Marta and for Khalid is $18 and $15 respectively.
Given that, the ratio of Marta’s hourly pay to Khalid’s hourly pay is 6:5.
What is the ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
Now, Marta’s hourly pay is 6x and Khalid’s hourly pay is 5x
Both Marta and Khalid get an increase of £1.50 in their hourly pay.
So, Marta’s hourly pay will be 6x+1.50 and Khalid’s hourly pay will be 5x+1.50
The ratio of Marta’s hourly pay to Khalid’s hourly pay after this increase is 13:11
Here, (6x+1.50)/(5x+1.50) =13/11
11(6x+1.50)=13(5x+1.50)
⇒ 66x+16.5=65x+19.5
⇒ x=3
So, Marta’s hourly pay is $18 and Khalid’s hourly pay is $15

write an equation using slope intercept form 4,-1 and 0,1
Answer:
y = -0.5x + 1
Step-by-step explanation:
The slope intercept form of a line is given by:
y = mx + b
where m is the slope of the line and b is the y-intercept (i.e. the point at which the line crosses the y-axis). To find the equation of a line using two points, we can use the slope formula to calculate the slope, then use one of the points to find the y-intercept.
The slope of a line is given by:
m = (y2 - y1) / (x2 - x1)
Substituting the coordinates of the two given points into this formula, we get:
m = (-1 - 1) / (4 - 0) = -2 / 4 = -1/2
Now that we know the slope of the line, we can use one of the points to find the y-intercept. Let's use the point (4,-1):
y = mx + b
-1 = (-1/2) * 4 + b
-1 = -2 + b
b = 1
Therefore, the equation of the line that passes through the points (4,-1) and (0,1) in slope intercept form is:
y = (-1/2)x + 1
Note that the equation can also be written as:
y = -0.5x + 1

The features of the function are given as follows:
Horizontal asymptote: y = 5.Vertical asymptote: x = 2.x-intercept: No x-intercept.y-intercept: (0,-5).Hole: No holes.What are the features of the function?The horizontal asymptote is the limit of f(x) as x goes to infinity. To obtain this limit, we consider only the terms with the highest exponent of the numerator and of the denominator, hence:
g(x) = -5x/x -> y = 5 is the horizontal asymptote.
The vertical asymptote is the value of x for which the function is not defined, hence it is the zero of the denominator, thus:
x - 2 = 0 -> x = 2.
The x-intercept is the point (x,0), in which x is found when y = 0, hence:
-5x + 10 = 0
-5x = -10
5x = 10
x = 2.
However, the function is not defined at x = 2, meaning that it has no x-intercept.
The y-intercept is the value of y when x = 0, hence:
y = 10/-2 = -5.
The coordinates are (0,-5).
The entire function can be simplified as follows:
(-5x + 10)/(x - 2) = [-5(x - 2)]/(x - 2) = -5.
Meaning that the function has no holes.

Lucinda has created a square pyramid mold for sand art. The sides of the base are each 11 inches, and the pyramid is 15 inches tall. Lucinda plans to full the pyramid three fourths full with colorful sand. How many cubic inches of the pyramid will contain sand?
Answer:
453.75
Step-by-step explanation:
To find the volume of a pyramid, we can use the formula V = (1/3)Bh, where V is the volume of the pyramid, B is the area of the base, and h is the height of the pyramid.
Since the base of the pyramid is a square, we can use the formula for the area of a square to find the area of the base. The formula for the area of a square is A = s^2, where A is the area of the square and s is the length of one side of the square. In this case, each side of the square base is 11 inches, so the area of the base is 11^2 = 121 square inches.
Now that we know the area of the base, we can use the volume formula to find the volume of the pyramid. The height of the pyramid is 15 inches, so the volume of the pyramid is V = (1/3) * 121 * 15 = 605 cubic inches.
Since Lucinda plans to fill the pyramid three fourths full with sand, the volume of the pyramid that will be filled with sand is 3/4 * 605 = <<3/4*605=453.75>>453.75 cubic inches.

jaci runs cross country for her high school. on average she runs 6 minutes per mile. What is the minutes used to ran 240 miles?
Consider the following expression and the simplified expression. Expression simplified expression 3 x squared + 5 y squared box + 3 box + 4 y squared + 6 9 x squared minus y squared + 9 which terms could be in the boxes to make the expressions equivalent?.
The simplified expression for the given problem will be :6x² and -10y²
Since the expression given to us is :
3 x² + 5 y²[] + 3 [] + 4 y²+ 6
= 3 x² + 5 y² + 4 y²[][]+6+3
=>3 x² + 9 y² [][]+9
The above equation is equal to 9 x²- y² + 9
=> 3 x² + 9 y² [][]+9 =9 x^2- y^2 + 9
now Equating the coefficients of x²and y² in LHS and RHS:
One box has = 9 x²- y²= +6x²
and the other will have = -y²- 9 = -10y²
