The size of an animal population in a year t is given by P(t)=210t+400/(t+2). Here t=0 represents the year 2004 and P(t) is the size of population in thousands of individuals. find the size of population in year 2004
The size of the animal population in year 2004 (t=0) is 200 thousands individuals.
What is population?Population is a term used to describe the total number of people that live in a specific geographic area. This can be a country, a state, a city, or any other area of the world. Population size and density are important factors in understanding the landscape of an area and its resources.
The size of the animal population in year 2004 (t=0) can be calculated by substituting t=0 into the given equation:
P(t)=210t+400/(t+2)
P(0)=210 × 0 + 400/(0+2)
P(0)=400/2
P(0)=200
Therefore, the size of the animal population in year 2004 (t=0) is 200 thousands individuals.

Integration by parts can only be used to integrate functions that include either polynomials or exponential functions. True False
Integration by parts can only be used to integrate functions that include either polynomials or exponential functions is False.
What is integration ?
Integration is a process of finding an antiderivative of a function, it is the reverse process of differentiation. It can be thought of as the area under the curve of the function or the accumulation of the function over a certain interval.
Integration by parts is a technique that can be used to integrate a wide variety of functions, not only functions that include polynomials or exponential functions. In fact, integration by parts can be used to integrate any function that can be expressed as the product of two functions, where one of the functions is the derivative of the other function. In other words, integration by parts allows us to evaluate an integral of the form ∫u(x)dv(x)dx by expressing it in terms of an integral of the form ∫v(x)du(x)dx.
It's just that those types of functions are more commonly used when applying this technique.

What is an inequality?
In Algebra, an inequality is a mathematical statement that uses the inequality symbol to illustrate the relationship between two expressions. An inequality symbol has non-equal expressions on both sides.
The given inequality is |x|>5.2.
So, the value of x should be greater than 5.2.
For example take x=6, then the given inequality will be -
|6|>5.2 = 6>5.2, so this is true.
Now take x=-6, then the given inequality will be -
|-6|>5.2 = 6>5.2, so this is also true.
Similarly, among the different choices x<-5.2 or x>5.2
The condition x>5.2 is already true.
Also, the condition x<-5.2 is also true for x if the value is lower than -5.2.
Therefore, the inequality x<-5.2 or x>5.2 is true.

The measure of an angle is 89
Find the measure of its supplement.
We can conclude that the supplement angle of 89° will be 91°.
What do we mean by supplement angles?Angles that add up to 180 degrees are referred to as supplementary angles.
For instance, angle 130° and angle 50° are complementary angles since the sum of these two angles is 180°.
The sum of complementary angles is 90 degrees.
Two angles are complementary if their sum equals 90 degrees, and supplementary if their sum equals 180 degrees.
So, we have an angle of 89°.
We know that the supplement angle is an angle of measure 180°.
Now, the supplement angle of 89° will be as follows:
180 - 89
91°
Therefore, we can conclude that the supplement angle of 89° will be 91°.

Tom works in chilled food department in a supermarket all fresh juices should be kept at a certain temperature as shown on thermometer
The temperature change that is required is; A reduction in temperature by 8°C.
How to find the change in temperature?We are told that;
The freezer should be working at -18°C.
The temperature on the freezer marks -10°C.
Now, what we see here is basic arithmetic because we simply want to find the additional temperature that will make the current reading to be equal to the ideal temperature required for it to wor. Thus, what we will do is to simply subtract the current temperature from the ideal one to find out the temperature required to make it work well.
Thus;
Temperature change = -18 - (-10)
Temperature change = -18 + 10
Temperature change = -8°C.

Which division is shown by the model 3/4 / 1/8
Answer:
6
Step-by-step explanation:
For dividing fractions it's also useful to know that the first fraction (3/4) is called the dividend and the second fraction (1/8) is called the divisor.
Here is a really quick way to divide fractions. In the divisor (the second fraction) we flip the numerator and the denominator. This is known as the reciprocal and basically it means the reverse of the fraction. When we find the reciprocal, we also have to change the division sign to a multiplication sign:
3/4 times 8/1
Once you've flipped the second fraction and changed the symbol from divide to multiply, we can multiply the numerators together and the denominators together and we have our solution:
So we multiply the numerators: 3x8=24
Then multiply the denominators: 4x1=4
Then we have the inproper fraction 24/4
So we divide 24 by 4 to make the answer a proper fraction
Finally you get your answer 6!

Given A = 5i +7j , B= 2i +3j Find the magnitude of A-B Select one: a.6 0 b. 5 c. 2 d. 4
In order to find the magnitude of a vector, we use the Pythagorean theorem. The magnitude, also known as the length or the norm, of a vector, is the square root of the sum of the squares of its components.
In this case, we are given two vectors A and B, which are defined as
A = 5i + 7j
B = 2i + 3j.
The i and j components represent the x and y values of the vector respectively.
To find the magnitude of vector A-B, we need to first find the difference between the two vectors. This can be done by subtracting the components of vector B from the corresponding components of vector A. So,
A-B = (5i + 7j) - (2i + 3j) = 3i + 4j.
Now we can use the Pythagorean theorem to find the magnitude of this vector. The square root of the sum of the squares of the x and y components of the vector is the magnitude of the vector. So, the magnitude of
A-B = √(3^2 + 4^2)
A-B = √(9 + 16)
A-B= √25
A-B = 5. Therefore, the answer is (b) 5.

To simplify fractions, we should follow these steps:
Step 1: Write the factors of the numbers in the numerator and denominator in step one.Step 2: Determine the shared factors that both the numerator and the denominator share.Step 3: At this point, we must divide the numerator and denominator by each other until there is only one other common component left.

v = -2*(1, 2, −2) + 7*(2, −1, 1)
w = -12*(1, 2, −2) + 11*(2, −1, 1)
What is the linear combination?
Linear combination is the process of adding two algebraic equations so that one of the variables is eliminated. Addition or subtraction can be used to perform a linear combination.
(a) z = (−3, −1, 1)
We can write z as a linear combination of the vectors in S by using the following equation:
z = as1 + bs2
Here, we can find the values of a and b by solving the following system of equations:
-3 = a1 + b2
-1 = a2 + b(-1)
1 = a*(-2) + b*1
Solving this system of equations, we get:
a = 5
b = -1
Therefore, z can be written as a linear combination of the vectors in S as:
z = 5*(1, 2, −2) -1*(2, −1, 1)
(b) v = (−2, −5, 5)
we can write v as a linear combination of the vectors in S by using the following equation:
v = as1 + bs2
Here, we can find the values of a and b by solving the following system of equations:
-2 = a1 + b2
-5 = a2 + b(-1)
5 = a*(-2) + b*1
Solving this system of equations, we get:
a = -2
b = 7
Therefore, v can be written as a linear combination of the vectors in S as:
v = -2*(1, 2, −2) + 7*(2, −1, 1)
(c) w = (1, −23, 23)
we can write w as a linear combination of the vectors in S by using the following equation:
w = as1 + bs2
Here, we can find the values of a and b by solving the following system of equations:
1 = a1 + b2
-23 = a2 + b(-1)
23 = a*(-2) + b*1
Solving this system of equations, we get:
a = -12
b = 11
Therefore, w can be written as a linear combination of the vectors in S as:
w = -12*(1, 2, −2) + 11*(2, −1, 1)
Therefore, The equation can be written as a linear combination of the vectors in S:
