Correct choice is B

Hi there! Assume that this is your question.

[tex] \large{ \int \limits^a_b ( {x}^{2} + 2x)dx}[/tex]

Before we get to Integral, you have to know Differentiation first. If you know how to differentiate a polynomial function then we are good to go in Integral!

We call the function that we are going to integrate as Integrand. Integrand is a function that's differentiated. In Integral, Integrating requires you to turn the function from differentiated to an original function.

For Ex. If the Integrand is x² then the original function is (1/3)x³ because when we differentiate (1/3)x³, we get x²

[tex] \large{f(x) = \frac{1}{3} {x}^{3} \longrightarrow f'(x) = {x}^{2} } \\ \large{f'(x) = 3( \frac{1}{3} ) {x}^{3 - 1} } \\ \large{f'(x) = {x}^{2} }[/tex]

So when we Integrate, make sure to convert Integrand as in original function. From the question, our Integrand is x²+2x. The function is in differentiated form. We know that x² is from (1/3)x³ and 2x comes from x²

[tex] \large{ f(x) = {x}^{2} \longrightarrow f'(x) = 2x} \\ \large{f'(x) = 2 {x}^{2 - 1} } \\ \large{f'(x) = 2x}[/tex]

Thus,

[tex] \large{ \int \limits^a_b ( {x}^{2} + 2x)dx} \\ \large{\int \limits^a_b ( \frac{1}{3} {x}^{3} + {x}^{2}) }[/tex]

Normally, if it's an indefinite Integral then we'd just put + C after (1/3)x³+x² but since we have a and b, it's a definite Integral.

[tex] \large{ \int \limits^b_a f(x)dx = F(b) - F(a)}[/tex]

Define F(x) as our anti-diff

From our problem, substitute x = a in then subtract with the one that substitute x = b

[tex] \large{ (\frac{1}{3}{a}^{3} + {a}^{2} ) - ( \frac{1}{3} {b}^{3} + {b}^{2}) }[/tex]

Simplify as we get:

[tex] \large \boxed{ \frac{1}{3}{a}^{3} + {a}^{2} - \frac{1}{3} {b}^{3} - {b}^{2}}[/tex]

Answer:

-8/3

Step-by-step explanation:

You can find the slope when given two points

m = (y2-y1)/(x2-x1)

    = ( -6-2)/ (3 -0)

    = -8/3

Answer:

7

Step-by-step explanation:

63 can be divided by 3, 7, 9, 21

27 can be divided by 3, 9

33 can be divided by 3, 11

Answer:

The correct answer is 7.

Step-by-step explanation:

A prime number is a number whose factors only include 1 and that number itself, examples of prime numbers would be 2 (1; 2), 5 (1; 5), and 11 (1; 11). In order to find the prime number, you must calculate all factors in each number. 63 has the following factors: 1; 3; 7; 9; 21; 63, so it isn't a prime number. 27 has the following factors: 1; 3; 9; 27, so it isn't a prime number. 33 has the following factors: 1; 3; 11; 33, so it also isn't a prime number. 7 only has two factors, 1 and 7, meaning that it is a prime number. Hence, this would be the correct answer.

Answer:

b² - 12b + 36

Step-by-step explanation:

use the FOIL method:

b² - 6b - 6b + 36

combine the 'like' terms in the middle:

b² - 12b + 36

Answer:

See below

Step-by-step explanation:

Given the expression

x(x-3) = 0

This can be written as x = 0 and x - 3 = 0

x = 0 and x = 0+3

x = 0 and x = 3

Hence the equation has 2 solutions since it is a quadratic equation

B) Given x^2 = -81

Take the square root of both sides

√x² = ±√-81

x =±√-81

Note that √-1 = i

x = ±9i

x = 9i and -9i

Hence this equation has 2 solutions because of its quadratic nature

C) (x−1)(x−1)=0

x - 1 = 0 and x = 1 = 0

x = 1 twice

Hence this equation has 1 solution because of its repitition of root

Step-by-step explanation:

Required

Function(s) with the same slope as function 1

The question is incomplete as function 1 and the three additional functions are not given.

However, I will provide a general explanation.

A slope is represented as:

[tex]y = mx + b[/tex]

Where

[tex]m \to[/tex] slope

So, considering the following equations

[tex]y = 2x + 3[/tex]

[tex]y = \frac{3x}{2} + 9[/tex]

[tex]y = 2x - 5[/tex]

[tex]y = -2x + 3[/tex]

The following equations have the same slope

[tex]y = 2x + 3[/tex] and [tex]y = 2x - 5[/tex]

Because: [tex]y = mx + b[/tex] implies that:

[tex]m = 2[/tex] for [tex]y = 2x + 3[/tex] and [tex]y = 2x - 5[/tex]

Answer:

(I don't understand 36 sorry, but I can help you with 35)

C. 5.7 feet

Step-by-step explanation:

35. This question is asking you to use the pythagorean theorem, this is the formula:

a² + b² = c²

--------

So we know the lengths of a and b,

a² = 16

b² = 16

We add those together:

16 + 16 = 32

-------

The next step is to calculate [tex]\sqrt{32}[/tex]

[tex]\sqrt{32}[/tex] ≈ 5.7

Answer:

Step-by-step explanation:

I could give a definition and list all of the international treaties. I could describe the obligations that states have to protect and defend human rights. I could get into the details in so many ways. But I won’t. And the reason why is because, in the end, it’s so simple. Human Rights are about recognizing the humanity in each person.

I guess you could get depressed and feel hopeless after four days of films and discussions about serious human rights issues like genocide and honour violence. But for me, at the end of this first Lund Human Rights Film Festival, the solution to many of our problems seems clearer than ever.

Hope that helps you..

Buhbye!

Answer:

human right mean everything to me and I think everyone should have human rights no matter who they are I help ever were and everyone to help them I hope you know what I mean

-5x + 4 - 3x² + 7x - 4

-3x² + 2x

Answer:

(–5x + 4) – (3X²–7x + 4) = ( – 3x² + 2x )

Answer:

0 ≤ x ≤ 30

Step-by-step explanation:

In the month of September, a bird population increased by a factor of 1.25 every day for those 30 days. The function below shows the number of birds, f(x), after x days:

f(x) = 250(1.25)ˣ

Which of the following is a reasonable domain for the function?

0 ≤ x ≤ 250

0 ≤ x ≤ 30

All positive integers greater than 100

All real numbers

Solution:

Given that f(x) = 250(1.25)ˣ, where x is the number of days and f(x) is the population of the birds after x days. This means that at the beginning of the month of September (i.e. at x = 0), the population of the birds was 250. And as each day goes by, the population of the bird increases by a factor of 1.25.

The domain of a function is the set of all possible independent variables. In this case the number of days (x) is the independent variable. Since in the month of September there are 30 days, therefore the domain is:

0 ≤ x ≤ 30

Answer:

[tex]-4[/tex]

Step-by-step explanation:

Step 1: Apply the rule

[tex]\left(-64\right)=-64\\\\=\sqrt[3]{-64}[/tex]

Step 2: Apply the radical rule

[tex]\sqrt[3]{-64}=-\sqrt[3]{64}\\\\=-\sqrt[3]{64}[/tex]

Step 3: Factor the number

[tex]\:64=4^3\\\\=-\sqrt[3]{4^3}[/tex]

Step 4: Apply the radical rule

[tex]\sqrt[3]{4^3}=4\\\\=-4[/tex]

Therefore, [tex]\:\sqrt[3]{\left(\:-\:64\right)}\:=\:-4[/tex]

Answer:

-4

Step-by-step explanation:

Answer: x = 2

Step-by-step explanation:

4x + 4 = 2x + 8

2x = 4

x = 2

Answer: x = 2.

Step-by-step explanation: 4x+4=2x+8 subtract 4 from both sides.

4x = 2x+4 subtract 2x on both sides

2x = 4        divide both sides by two

x = 2

Answer:

86.70 cm^2

Step-by-step explanation:

circumference = 11 x 3 = 33

circumference of a circle =  nD

33 = 3.14 X D

D = 10.51

r = 10.51 / 2 = 5.25

Area = nr^2

3.14 x 5.25^2 = 86.70 cm^2

So, Vanessa's score = v. Let's work from there.

We know that 59 is decreased by Vanessa's score, which is subtraction, and thus: 59 - v

Then, we're told that that quantity is 7. "Is" can be used in place of an equals sign: = 7

Therefore, our equation is as follows: 59 - v = 7

Hope this helps!! :)

Answer:

A negtive linear accosian

Step-by-step explanation:

Answer:

[tex](a)\ -16t^2 + 7t + 63=0[/tex]

[tex](b)\ t = 2.215[/tex]

Step-by-step explanation:

Given

[tex]h(t) = -16t^2 + 7t + 63[/tex]

Solving (a): Equation when it hits the ground.

This means that [tex]h(t) = 0[/tex]

So, we have:

[tex]h(t) = -16t^2 + 7t + 63[/tex]

[tex]-16t^2 + 7t + 63=0[/tex]

Solving (b): The value of t in (a)

[tex]-16t^2 + 7t + 63=0[/tex]

Using quadratic formula, we have:

[tex]t = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}[/tex]

This gives:

[tex]t = \frac{-7 \± \sqrt{7^2 - 4*-16*63}}{2*-16}[/tex]

[tex]t = \frac{-7 \± \sqrt{49+ 4032}}{2*-16}[/tex]

[tex]t = \frac{-7 \± \sqrt{4081}}{-32}[/tex]

[tex]t = \frac{-7 \± 63.88}{-32}[/tex]

Split

[tex]t = \frac{-7 + 63.88}{-32}; or\ t = \frac{-7 - 63.88}{-32}[/tex]

[tex]t = \frac{56.88}{-32}; or\ t = \frac{-70.88}{-32}[/tex]

[tex]t = -1.7775; or\ t = 2.215[/tex]

Time can't be negative; So:

[tex]t = 2.215[/tex]

Answer:

54

Step-by-step explanation:

Complementary angles add up to equal 90

If ∠1 and ∠2 are complementary angles then ∠1 + ∠2 = 90

if ∠1 = 36 then 36 + ∠2 = 90

90 - 36 = 54

Hence, ∠2 = 54
