Find p(–4) if p(x) = 3x^3 – 2x^2 + 6x – 4



If r(x) = x^3 – 2x + 1, find r(2a^3).

Answers

Answer 1

Answer:

I think that the first part would be -252, but I'm not sure about the second part

Step-by-step explanation:

Answer 2

Find p(–4) if p(x) = 3x^3 – 2x^2 + 6x – 4

p(-4) = 3x^3 – 2x^2 + 6x – 4

p(-4) = 3(-4)^3 – 2(-4)^2 + 6(-4) – 4
= 3(-64) - 2(16) + 6(-4) - 4
= -192 - 32 - 24 - 4
p(-4) = -252


r(x) = x^3 – 2x + 1, find r(2a^3)

r(x) = (x^3 – 2x + 1) (2a^3)
= (2a^3) x^3 + (2a^3) (-2x) + (2a^3) * 1
= x^3 (2a^3) - 2x (2a^3) + 1 * (2a^3)
r(x) = 2a^3x^3 - 4a^3x + 2a^3

I’m not entirely sure about this one as I’m also in 11th grade but I think this is how it’s done.

Someone please help me on this I'm unsure if my answer is correct

Answers

Answer:

A. length = 23 cm; width = 5 cm

Step-by-step explanation:

So if 4 times the width would be [tex]4w[/tex] and 3 more than would be [tex] + 3[/tex], the equation would be [tex]l = 4w + 3[/tex]. If the perimeter is 56, then the new equation, [tex]2(4w + 3) + 2(w) = 56[/tex] can be formed. This simplifies to [tex]8w + 6 + 2w = 56[/tex], then to [tex]10w + 6 = 56[/tex], then to [tex]10w = 50[/tex], and finally, [tex]w = 5[/tex]. So the width is 5, and now plug it into the first equation.

[tex]l = 4(5) + 3[/tex], becomes [tex]l = 20 + 3[/tex], becomes [tex]l = 23[/tex].

So the dimensions are: length = 23 cm, width = 5 cm.

*And just to be sure, [tex]2(23 + 5) = 2(28) = 56[/tex] which is correct.

What are the zeroes of f(x)=(2x+3)(x-5)?

Answers

———————————————————a

Answer:

[tex]-\frac{3}{2} , 5[/tex]

Step-by-step explanation:

The zeroes of a function are the x values of the points at which the graph intersects the x-axis. All points on the x-axis have a y-value of 0, therefore, we need to find out which values of x can be plugged in to have the result be 0. This function is already factored out. So, for each expression, find which input of x makes the result equal 0.

1) So, start with 2x + 3. Set it equal to 0 and solve for x:

[tex]2x + 3 = 0\\2x = -3\\x = -\frac{3}{2} \\[/tex]

Therefore, [tex]-\frac{3}{2}[/tex] is one of the zeroes.

2) Next, set x-5 equal to 0 and solve, too:

[tex]x - 5 = 0 \\x = 5 \\[/tex]

Therefore, 5 is one of the zeroes.

3) Thus, the zeroes are [tex]-\frac{3}{2}[/tex] and 5.

Jared has 12 more comic books than Zoe. If they have 28 comic books
altogether, find the number of comic books Jared has.
Your answer

Answers

Answer:

20 comic books

Step-by-step explanation:

Let us first set up a variable, x, for the number of books that Zoe has. If Jared has 12 more comics than Zoe, he would have x+12 books.

Given that Zoe and Jared have a total of 28 comic books, let us write an equation and solve for x:

[tex]x+x+12=28\\2x+12=28[/tex]

Now that we have a simplified version of the equation, let us solve for x by isolating the variable on the left side:

[tex]2x=28-12\\2x=16\\x=8[/tex]

We now know that x=8, and also that Jared has x+12 books. To find the number of comic books Jared has, let us add 12 to x:

[tex]x+12=\\8+12=\\20\\[/tex]

Therefore, Jared has 20 comic books.

I hope this helps! Please let me know if you have any further questions :)

A dollar bill is about 0.00011 meter thick. What is this thickness in scientific notation?​

Answers

Answer:

1.1 * 10 ^ -3

Step-by-step explanation:

Given the value of the thivkness of a dollar bill to be 0.0011metre

The standard scientific notation is expressed as A * 10^n

A is any value between 1 and 10 where n is any integer

0.0011 = 11/10000

0.0011 = 11 *1/1000

0.0011 = 11 * 0.0001

0.0011 = 1.1 * 0.001

0.011 = 1.1 * 10 ^ -3 (Note that the decimal point is shifted forward three times and the power is negative because the value is less than 1)

C. 15/18
D. 27/36

Answers

Answer:

B and C

Step-by-step explanation:

First you have to find a common denominator which would be 18. Then you need to multiply the denominators to get to 18. 6x3 and 9x2. Now whatever you do to the bottom you have to do to the top. So you would mutiply 5x3 and 7x2. The fractions you are left with are, 14/18 and 15/18.

To solve the problem we need to know about fractions.

What is Fraction?

A fraction is a way to describe a part of a whole. such as the fraction [tex]\frac{1}{4}[/tex]can be described as 0.25.

Given to us

Mike made 5/6 of his free throw attempts Lisa made 7/9 of her free throw attempts

LCM of Denominator

To bring the denominator, we need to take the LCM of the denominator, therefore,

[tex]\dfrac{5}{6},\ \dfrac{7}{9}[/tex]

we know that the LCM of 6 and 9 is 18. therefore,

[tex]=\dfrac{(5\times 3)}{(6\times 3)},\ \dfrac{(7\times 2)}{(9\times 2)}\\\\=\dfrac{15}{18},\ \dfrac{14}{18}[/tex]

Thus,

Option D is the correct answer.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

From the figure,

3x + 46 + 14 = 90

Now,

Simplifying.

3x + 60 = 90

Subtracting 60 on both sides.

3x = 90 - 60

3x = 30

Dividing 3 into both sides.

x = 10

Thus,

The value of x on the given figure is 10.

They made a difference in peoples lives and learned some important life lessons in the process. Organizations, including schools, are actively promoting service for all citizens as a way to be involved, help others, and improve themselves. Service is helping other people and being active in your community. For example, one group of teens planted a community garden with their friends. They grow a variety of vegetables. The garden requires regular care. The teens donate the produce to a local soup kitchen. Workers there use the produce to help feed people in the community. By tending the garden and donating their produce, the teens are actively helping make life a bit better for others in their community. Service is valuable in ways that cannot be measured in dollars. People volunteer or serve others without expecting money or gifts in return. Service is not about earning money. It is not just collecting money to give to a group. It is about action and contributing to the common good. The people who serve as well as those who receive help benefit in many ways that are more important than money or gifts. For example, a soup kitchen provides essential food to people who may otherwise go hungry. The soup kitchen is extremely valuable for those struggling to get enough to eat. Those serving learn about compassion and how helping others can improve life for all. Millions of Americans are making society better for themselves and for others. They are participating citizens in their community, raising up those who are less fortunate. In return, they become better people who can understand the perspectives and needs of others, which are invaluable and important qualities of good citizens.What is the main idea of this article excerpt?Service means helping others in the community.
