We only need the function f(x), the constants C will cancel each other out:
[tex]f(x) = (1/3)x^3 - (1/3)(x-7)^3[/tex]
This is the function f(x) after applying the Second Fundamental Theorem of Calculus.
To find the function f(x) using the Second Fundamental Theorem of Calculus, we need to evaluate the definite integral from x-7 to x of the given function. \
The integral is:
[tex]f(x) = \int (x-7)^x \sqrt{(t^4)} dt[/tex]
First, let's simplify the integrand:
[tex]\sqrt{(t^4) } = t^2[/tex]
Now the integral becomes:
[tex]f(x) = \int (x-7)^x t^2 dt[/tex]
According to the Second Fundamental Theorem of Calculus, if F(t) is the antiderivative of the integrand t^2, then:
f(x) = F(x) - F(x-7)
To find the antiderivative F(t), we integrate [tex]t^2[/tex] with respect to t:
[tex]F(t) = \int t^2 dt = (1/3)t^3 + C[/tex]
Now, apply the theorem:
[tex]f(x) = F(x) - F(x-7) = (1/3)x^3 + C - [(1/3)(x-7)^3 + C][/tex]
Since we only need the function f(x), the constants C will cancel each other out:
[tex]f(x) = (1/3)x^3 - (1/3)(x-7)^3[/tex]
This is the function f(x) after applying the Second Fundamental Theorem of Calculus.

To use the second fundamental theorem of calculus to find f(x) = integral x-7^x sqrt(t^4 7 dt, we first need to find the antiderivative of the integrand. Using the power rule of integration, we can simplify the integrand to t^2*sqrt(7)*sqrt(t^2)^2, which becomes (1/3)t^3*sqrt(7).
Now, we can apply the second fundamental theorem of calculus, which states that if F(x) is the antiderivative of f(x), then integral from a to b of f(x) dx = F(b) - F(a).
Thus, f(x) = (1/3)t^3*sqrt(7), F(x) = (1/3)x^3*sqrt(7), and the integral from x-7 to x of f(x) dx becomes F(x) - F(x-7) = (1/3)x^3*sqrt(7) - (1/3)(x-7)^3*sqrt(7).
Therefore, the value of f(x) = integral x-7^x sqrt(t^4 7 dt is (1/3)x^3*sqrt(7) - (1/3)(x-7)^3*sqrt(7).

Is 30% of 70 is the same as 3/7 of 70?
Answer:
No
Step-by-step explanation:
30% is the same as 3/10
3/7 is about the same as 43%
There is a difference among the percentage so no it's not correct
Yes, the value 30% of 70 is the same as 3/7 of 70.
What is an expression?Expression in maths is defined as the relation of numbers variables and functions by using mathematical signs like addition, subtraction, multiplication, and division.
To show this mathematically, we can start by calculating 30% of 70:
30% of 70 = (30/100) x 70
= 0.3 x 70
= 21
Now, let's calculate 3/7 of 70:
3/7 of 70 = (3/7) x 70
= 30/100 x 70
= 0.3 x 70
= 21
As we can see, both calculations give us the same result of 21. Therefore, 30% of 70 is the same as 3/7 of 70.

Step-by-step explanation:
Most of the geometry concepts and theorems that are learned in high school today were first discovered and proved by mathematicians such as Euclid thousands of years ago. Given that these geometry concepts and theorems have been known to be true for thousands of years, why is it important that you learn how to prove them for yourself?
Theorems and Proofs
In geometry, a postulate is a statement that is assumed to be true based on basic geometric principles. An example of a postulate is the statement “through any two points is exactly one line”. A long time ago, postulates were the ideas that were thought to be so obviously true they did not require a proof. A theorem is a mathematical statement that can and must be proven to be true. You've heard the word theorem before when you learned about the Pythagorean Theorem. Much of your future work in geometry will involve learning different theorems and proving they are true.
What does it mean to “prove” something? In the past you have often been asked to “justify your answer” or “explain your reasoning”. This is because it is important to be able to show your thinking to others so that ideally they can follow it and agree that you must be right. A proof is just a formal way of justifying your answer. In a proof your goal is to use given information and facts that everyone agrees are true to show that a new statement must also be true.
Suppose you are given the picture below and asked to prove that AD¯¯¯¯¯¯¯¯≅DC¯¯¯¯¯¯¯¯. This means that you need to give a convincing mathematical argument as to why the line segments MUST be congruent.
Here is an example of a paragraph-style proof. This is similar to a detailed explanation you might have given in the past.
AB¯¯¯¯¯¯¯¯≅BC¯¯¯¯¯¯¯¯ because it is marked in the diagram. Also, ∠ADB and ∠CDB are both right angles because it is marked in the diagram. This means that △ADB and △CDB are right triangles because right triangles are triangles with right angles. Both triangles contain segment BD¯¯¯¯¯¯¯¯. BD¯¯¯¯¯¯¯¯≅BD¯¯¯¯¯¯¯¯ because of the reflexive property that any segment is congruent to itself. △ADB≅△CDB by HL≅ because they are right triangles with a pair of congruent legs and congruent hypotenuses. AD¯¯¯¯¯¯¯¯≅DC¯¯¯¯¯¯¯¯ because they are corresponding segments and corresponding parts of congruent triangles must be congruent.
There are two key components of any proof -- statements and reasons.
The statements are the claims that you are making throughout your proof that lead to what you are ultimately trying to prove is true. Statements are written in red throughout the previous proof.
The reasons are the reasons you give for why the statements must be true. Reasons are written in blue throughout the previous proof. If you don't give reasons, your proof is not convincing and so is not complete.
When writing a proof, your job is to make everything as clear as possible, because you need other people to be able to understand and believe your proof. Skipping steps and using complicated words is not helpful!
There are many different styles for writing proofs. In American high schools, a style of proof called the two-column proof has traditionally been the most common (see Example 3). In college and beyond, paragraph proofs are common. An example of a style of proof that is more visual is a flow diagram proof (see Example 4). No matter what style is used, the key components of statements and reasons must be present. You should be familiar with different styles of proof, but ultimately can use whichever style you prefer.
Learning to write proofs can be difficult. One of the best ways to learn is to study examples to get a sense for what proofs look like.

What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
let p the number of pennies, d be the number of dimes, n be the number of nickels and q be number of quarters.
So, the expressions are
p = 3d
n = d+1
= 5(d+1)
d = 10d
and, q = 2d
= 25 (2d)
and, the total is = $209
= 209
Then,
3d + 5(d+ 1) + 10d +25 ( 2d) = 209
68d + 5 = 209
d = 3
Thus, the number of quarters = 2d = 6 quarters.

I want you to do a linear and exponential model for Yakima's Population. Use the DATA below: in 1990 => P0 = 64792 in 2010 => P20 = 91646 A) Find the linear model of population growth. B) Predict the population for 2050. C) Find the exponential model of population growth. D) Predict the population for 2050. E) Which one seems more realistic?
Answer:
(a) [tex]P(x) = 1342.7x + 64792[/tex]
(b) [tex]P(60) = 145354[/tex]
(c) [tex]P(x) = 64792 *1.0175^x[/tex]
(d) [tex]P(60) = 183491[/tex]
(e) The exponential model is more realistic
Step-by-step explanation:
Given
[tex]1990 ==> P_0 =64792[/tex]
[tex]2010 ==> P_{20} =91646[/tex]
Solving (a): The linear model of the population growth
First, we calculate the slope of the function.
[tex]m = \frac{P_{20} - P_0}{20 - 0}[/tex]
[tex]m = \frac{91646 - 64792}{20 - 0}[/tex]
[tex]m = \frac{26854}{20}[/tex]
[tex]m = 1342.7[/tex]
The linear equation is then calculated using:
[tex]P(x) - P_0 = m(x - x_0)[/tex]
[tex]P(x) - 64792 = 1342.7(x - 0)[/tex]
[tex]P(x) - 64792 = 1342.7(x)[/tex]
[tex]P(x) - 64792 = 1342.7x[/tex]
Make P(x) the subject
[tex]P(x) = 1342.7x + 64792[/tex]
Solving (b): The population in 2050
First, calculate x:
[tex]x = 2050 - 1990[/tex]
[tex]x = 60[/tex]
Substitute 60 for x in [tex]P(x) = 1342.7x + 64792[/tex]
[tex]P(60) = 1342.7 * 60 + 64792[/tex]
[tex]P(60) = 80562 + 64792[/tex]
[tex]P(60) = 145354[/tex]
The population in 2050 is 145354
Solving (c): The exponential model of the population growth
An exponential model is:
[tex]y = ab^x[/tex]
In this case, it is:
[tex]P(x) = P_0 * b^x[/tex]
For x = 20, we have:
[tex]P(20) = P_0 * b^{20[/tex]
Substitute values for P(20) and P0
[tex]91646 = 64792 * b^{20[/tex]
Divide both sides by 64792
[tex]\frac{91646 }{64792} = \frac{64792 * b^{20}}{64792}[/tex]
[tex]\frac{91646 }{64792} = b^{20}[/tex]
[tex]1.41446474873 = b^{20}[/tex]
Take the 20th root of both sides
[tex]\sqrt[20]{1.41446474873} = b[/tex]
[tex]b = \sqrt[20]{1.41446474873}[/tex]
[tex]b = 1.0175[/tex]
So, the model is:
[tex]P(x) = P_0 * b^x[/tex]
[tex]P(x) = 64792 *1.0175^x[/tex]
Solving (d): The population in 2050
First, calculate x:
[tex]x = 2050 - 1990[/tex]
[tex]x = 60[/tex]
Substitute 60 for x in [tex]P(x) = 64792 *1.0175^x[/tex]
[tex]P(60) = 64792 *1.0175^{60[/tex]
[tex]P(60) = 64792 *2.832[/tex]
[tex]P(60) = 183490.944[/tex]
[tex]P(60) = 183491[/tex] ---- approximated
(e) The most realistic model
The exponential model is more realistic. This is so because:
The linear model grows at a constant linear rate which means that, every year a certain amount of individuals is added to the society. However, this is not always so because it is almost impossible to for growth rate to be constant
A curve in the exponential model shows that the addition of individuals in the society every year is not always constant.

Step-by-step explanation:
∠ QRS = ∠ YRT = 110° ( vertically opposite angles )
∠ PQR = 180° - 120° = 60° ( adjacent angles )
The sum of the interior angles of a quadrilateral = 360°
Sum the angles and equate to 360°, that is
110 + 60 + x + 80 = 360
250° + x = 360° ( subtract 250° from both sides )

Solve the triangle. Round decimal answers to the nearest tenth.
Answer:
x = 5.7 y = 9.4
m∠H = 31°
Step-by-step explanation:
cos of an angle = adjacent side/hypotenuse
and sine of an angle = opposite side/hypotenuse
cos 59 = x/11 and sin 59 = y/11
11 cos 59 = x 11 sin 59 = y
x = 5.7 y = 9.4
m∠H = 90 - 59 = 31°
You need to memorize the definitions of all the trig functions and then these types of problems will be easy for you.
[tex]x=5.7[/tex], [tex]y=9.4[/tex] and ∠[tex]H[/tex][tex]=31[/tex]° is the solution of the triangle.
What is trigonometric ratio?
Trigonometric ratios are the ratios of the length of sides of a triangle. These ratios in trigonometry relate the ratio of sides of a right triangle to the respective angle.
The basic trigonometric ratios formulas are given below :
sin θ = Perpendicular/Hypotenuse
cos θ = Base/Hypotenuse
tan θ = Perpendicular/Base
sec θ = Hypotenuse/Base
cosec θ = Hypotenuse/Perpendicular
cot θ = Base/Perpendicular
What is the sum of angle of triangle?The sum of angles of a triangle equals the straight angle (180 degrees, π radians, two right angles, or a half-turn)
According to question,
In Δ FGH ,
∠G = 59°
Hypotenuse of triangle = 11
Base of triangle according to the ∠G = x
Perpendicular of triangle according to the ∠G = y
Now,
Cosθ = [tex]\frac{Base}{Hypotenuse}[/tex]
[tex]Cos[/tex] 59° = [tex]\frac{x}{11}[/tex]
[tex]x[/tex] [tex]=11[/tex]× [tex]0.515[/tex] ( Cos59° = [tex]0.515[/tex] )
x [tex]=5.7[/tex]
Sinθ = [tex]\frac{Perpendicular}{Hypotenuse}[/tex]
[tex]Sin[/tex] [tex]59[/tex]° [tex]=\frac{y}{11}[/tex]
[tex]y=11[/tex] * 0.857
y [tex]=9.4[/tex]
According to the sum of angle of triangle
∠F + ∠G +∠H = 180°
90° + 59° + ∠H = 180°
∠H = 180° - 90 -59
∠H = 31°
Hence,[tex]x=5.7[/tex], [tex]y=9.4[/tex] and ∠[tex]H[/tex][tex]=31[/tex]° is the solution of the triangle.

Answer: 132.67 to the power of 2 (inches)
Step-by-step explanation:
The circumference of a circle is given as 2πr. Therefore, in his case,
2πr = 40.82
2 × 3.142 × r = 40.82
6.284r = 40.82
radius = 40.82/6.284
radius = 6.5 inches
Area will now be:
= πr²
= 3.142 × 6.5²
= 3.142 × 42.25
= 132.75 inches²
Therefore, the closest answer will be 132.67 to the power of 2 (inches).
