Step-by-step explanation:

[tex]\frac{5w+4}{3}=\frac{3w}{2}[/tex]

Cross-multiplying,

[tex]2(5w+4)=9w\\10w+8=9w\\w+8=0\\w=\boxed{-8}[/tex]

Use the remainder theorem: we can decompose the given polynomial in terms of quotient and remainder polynomials [tex]q(x)[/tex] and [tex]r(x)[/tex], respectively, such that

[tex]x^4 - 5x^3 + x^2 - 10x - 5 = (x + 3) q(x) + r(x)[/tex]

Then letting x = -3 makes the quotient term vanish, and we're left with a remainder of

[tex]r(-3) = (-3)^4 - 5\times(-3)^4 + (-3)^2 - 10\times(-3) - 5 = \boxed{250}[/tex]

A function assigns the values. The function of the given graph is y=3(4)ˣ, thus, the correct option is C.

A function assigns the value of each element of one set to the other specific element of another set.

The complete question is:

If the parent function is y = 4ˣ, which is the function of the graph?

y = −2(4)ˣ

y = −3(4)ˣ

y = 3(4)ˣ

y = 2(4)ˣ

Since the graph intersect the y-axis at 3, and the parent function of the function is y=4ˣ, therefore, we can write,

y = A(4)ˣ

3 = A(4)⁰

3 = A × 1

A = 3

Hence, the function of the given graph is y=3(4)ˣ, thus, the correct option is C.

NOTE :

the sum of the 4 interior angles of a quadrilateral is 360°.

…………………………………………

Then

h + h + 2h + 2h = 360

Then

6h = 360

Then

h = 360 ÷ 6 = 60

Then

2h = 2 × 60 = 120

The area and the perimeter of the figure will be 38.13 in² and 23.42 inches respectively.

The area will be:

Answer:

square root = not polynomial

Pile Y has the greater mean number of pages per book because it is 5 books less than pile W.

From the complete information, we can deduce that the number of each pile of book is given as follows:

For pile W;

Red books = 10 × 5 = 50 red books.

Blue books = 5 × 5 = 25 blue books.

Therefore, total books in pile W = 50 + 25 = 75 books.

Mathematically, the mean for each pile can be calculated by using the following formula:

Mean = [F(x)]/n

Mean = 75/10

Mean = 7.5.

For pile Y;

Red books = 10 × 5 = 50 red books.

Mean = [F(x)]/n

Mean = 50/5

Mean = 10.

In conclusion, pile Y has the greater mean number of pages per book because it is 5 books less than pile W.

A reciprocal is a number or fraction flipped. So, 5 1/2=11/2. 11/2 flipped is 2/11.

Answer:

The Median Best Describes The Monthly Rents

the mean is add up all the numbers and then divide by the amount of numbers so it is 4820 then divide by 5 = 964 so the mean of all of then is 964

the median you have to put it in slamets to biggest so 650 650 800 820 1900 and then you have to put the one(s) in the middle witch is 800 so the median is 800

the mode is the most common numbers that show up and there is 2 650 and one of everything else so the mode is 650

5/11 odds  /   45.45% chance of being even-numbered

Step-by-step explanation:

There are 5 even-numbered balls (2, 4, 6, 8, 10) and 6 odd-numbered balls  (1, 3, 5, 7, 9, 11). So, 5 / 11 balls are even-numbered

if a ball is selected, it has a chance of 5/11 for being even-numbered

5/11 also = 45.45 % [rounded] chance of being even-numbered    

A function assigns the value of each element of one set to the other specific element of another set. The inverse of the function g(x)=-2x -3.

A function assigns the value of each element of one set to the other specific element of another set.

Two function are inverse of each other if,

f(g(x))=x

g(f(x)) = x

Since the function is inverse, therefore, we can write,

g(f(x)) = a(-1x/2 - 3/2) + b

x = -ax/2 - 3x/2 + b

-a/2 = 1

a = -2

-3a/2 + b = 0

b= -3

Thus, the inverse of the function g(x)=-2x -3.

The number of ways to check off one answer to each question is; 20ways.

The number of ways to check off one answer to each question and get it wrong is; 15ways.

a) Since each question has four possible answers, it therefore follows that the student can choose any of 4 options in each question and consequently, the number of different ways is; 4 × 5 = 20.

b) Since only one option is correct, it follows that there are 3 wrong choices in each question case and hence, the number of ways to pick one wrong answer is; 3 × 5 = 15.

Step-by-step explanation:

x = number of small boxes

y = number of large boxes

these equations model the situation :

x + y = 8

12x + 45y = 195

FYI - the solution :

from the first equation we get

x = 8 - y

we use that in the second equation

12(8 - y) + 45y = 195

96 - 12y + 45y = 195

33y = 99

y = 3

x = 8 - y = 8 - 3 = 5

Find when f(x) = 0. By factorizing, we have

-x² + 8x - 7 = - (x - 7) (x - 1) = 0

so either x - 7 = 0 or x - 1 = 0, or simply x = 1 or x = 7.

Split the domain into three intervals, and check the sign of f(x) over each interval at some test point in the interval. The sign will tell you when the icicle is dripping (positive) or not (negative).

• [0, 1) : at x = 0, we have f(0) = -7 < 0

• (1, 7) : at x = 2, we have f(2) = 5 > 0

• (7, 10] : at x = 8, we have f(8) = -7 < 0

This tells us that the icicle is not dripping when 0 ≤ x < 1, begins to drip when x = 1, drips for the duration of 1 < x < 7, stops dripping when x = 7, and keeps on not dripping when 7 < x ≤ 10.
