The given polynomial is
x^2 - 9x^3 - 5x^2 - 4x + 5
By simplifying it, it becomes
- 9x^3 + x^2 - 5x^2 - 4x + 5
- 9x^3 - 4x^2 - 4x + 5
We want to divide it by x + 3. To use the remainder theorem, we would substitute x = - 3 into the polynomial to find the remainder, r. We have
r = p(- 3) = -9(-3)^3 - 4(-3)^2 - 4(-3) + 5
243 - 36 + 12 + 5
r = 224
Thus, the remainder when P(x) = x^2-9x^3-5x^2-4x+5 is divided by x + 3 is 224
P(-3) = 224

Triangle UVW has vertices at U(−2, 0), V(−3, 1), W(−3, 3). Determine the vertices of image U′V′W′ if the preimage is rotated 180° counterclockwise.
U′(0, −2), V′(−1, −3), W′(−3, −3)
U′(0, −2), V′(1, −3), W′(3, −3)
U′(2, 0), V′(3, −1), W′(3, −3)
U′(−1, 0), V′(−3, 0), W′(3, −3)
To determine the vertices of image U′V′W′ after a 180° counterclockwise rotation, we can apply the following transformation rules:
A 180° counterclockwise rotation of a point (x, y) about the origin produces the point (-x, -y).To perform a rotation of a polygon, we apply the transformation rule to each vertex of the polygon.Using these rules, we can find the vertices of image U′V′W′ as follows:
Vertex U(-2, 0) is transformed to U′(0, -2), since (-(-2), -(0)) = (2, 0) becomes (0, -2) after the rotation.Vertex V(-3, 1) is transformed to V′(1, -3), since (-(-3), -(1)) = (3, -1) becomes (1, -3) after the rotation.Vertex W(-3, 3) is transformed to W′(3, -3), since (-(-3), -(3)) = (3, 3) becomes (3, -3) after the rotation.Therefore, the vertices of image U′V′W′ after a 180° counterclockwise rotation are U′(0, -2), V′(1, -3), and W′(3, -3).
So, the answer is option (b) U′(0, −2), V′(1, −3), W′(3, −3).

To the nearest tenth, find the missing length of an isosceles right triangle with legs that measure 12 cm.
The missing length of an isosceles right triangle with legs that measure 12 cm is given as follows:
17 cm.
What is the Pythagorean Theorem?The Pythagorean Theorem states that for a right triangle, the length of the hypotenuse squared is equals to the sum of the squared lengths of the sides of the triangle.
In an isosceles right triangle, the two legs have an equal measure, which for this problem is of 12 cm.
Then the missing length is the hypotenuse, obtained with the Pythagorean Theorem as follows:
h² = 12² + 12²
h = sqrt(12² + 12²)
h = 16.97 cm.
h = 17 cm. -> rounded to the nearest tenth.

The scatter plot and line of best fit show the relationship between the number of pancakes eaten and volume of syrup used.
Answer:
the answer is C
Step-by-step explanation:
Okay an explanation:
so basically the graph above shows that for each pancake eaten then 1/4 of a cup of syrup is used
thus 1/4×4=1 (full cup of syrup) meaning that for every cup of syrup, 4 pancakes are eaten
the other answers are incorrect because:
a) answer a describes that for every pancake eaten, one cup of syrup is used this is incorrect as the units on the y axis dont match up with the x axis or the statement claimed.
b) the line for the graph with describes the relation between cup of syrup used per pancake goes up to 2.75 cups of syrup which would only mean that we were ro make an assumption > inaccurate

Which one of these relationships is different than the other three? Write the equation for each line,or find the slope (one of them is different from the other3)
Answer:
Graph B is different from the others.
Equation for Graph A, C, and D is \( y = 5x \).
Equation of Graph B is \( y = 5.5x \)
Step-by-step explanation:
The equation of each line can be written as \( y = mx \), where m is the slope.
Using each point given in each graph, we can find m and also an equation for each graph:
✍️Graph A Equation and slope:
Using the point given, (0.8, 4), the slope, m, can be calculated as,
\( m = \frac{y}{x} = \frac{4}{0.8} = 5 \)
Substitute m = 5 into \( y = mx \).
✅Equation for graph A would be \( y = 5x \).
✍️Graph B Equation and slope:
Using the point given, (10, 55), the slope, m, can be calculated as,
\( m = \frac{y}{x} = \frac{55}{10} = 5.5 \)
Substitute m = 5.5 into \( y = mx \).
❌Equation for graph B would be \( y = 5.5x \).
✍️Graph C Equation and slope:
Using the point given, (4, 20), the slope, m, can be calculated as,
\( m = \frac{y}{x} = \frac{20}{4} = 5 \)
Substitute m = 5 into \( y = mx \).
✅Equation for graph C would be \( y = 5x \).
✍️Graph D Equation and slope:
Using the point given, (10, 50), the slope, m, can be calculated as,
\( m = \frac{y}{x} = \frac{4}{0.8} = 5 \)
Substitute m = 5 into \( y = mx \).
✅Equation for graph D would be \( y = 5x \).
Equation for Graph A, C, and D is \( y = 5x \).

. what is the probability that a five-card poker hand contains two pairs (that is, two of each of two different kinds and a fifth card of a third kind)?
The probability of obtaining a five-card poker hand that contains two pairs is approximately 0.0475, or 4.75%.
To calculate the probability of obtaining a five-card poker hand with two pairs, we need to determine the number of favorable outcomes (hands with two pairs) and the total number of possible outcomes (all possible five-card hands).
A hand with two pairs consists of two cards of one rank, two cards of another rank, and a fifth card of a different rank. There are 13 ranks to choose from, and for each rank, we can choose 2 out of the 4 cards to form the pairs. The fifth card can be any of the remaining 11 ranks.
The number of ways to select two ranks for the pairs is given by C(13, 2) = 78. For each pair rank, there are C(4, 2) = 6 ways to select the two cards. The fifth card can be chosen from the remaining 11 ranks in C(11, 1) = 11 ways.
Therefore, the number of favorable outcomes is 78 × 6 × 6 × 11 = 37,368.
The total number of possible five-card hands is C(52, 5) = 2,598,960.
Thus, the probability of obtaining a hand with two pairs is 37,368 ÷ 2,598,960 ≈ 0.0475, or 4.75%.

Each student in Mr. Kelly's shop class needs a piece of wood13-foot long to complete a project. Mr. Kelly has one piece of wood that is716-foot long.How many pieces that are exactly13-foot long can be made from Mr. Kelly's longer piece of wood?
From Mr. Kelly's longer piece of wood, he can make 55 pieces that are exactly 13 feet long.
To calculate the number of 13-foot pieces that can be made from the longer piece of wood, we need to divide the length of the longer piece by the length of each individual piece. In this case, the longer piece of wood is 716 feet long, and each student needs a piece of wood that is 13 feet long.
Dividing 716 by 13 gives us the quotient of 55.0769. Since we cannot have a fraction of a piece, we round down to the nearest whole number, which is 55. Therefore, Mr. Kelly can make 55 pieces that are exactly 13 feet long from the longer piece of wood.
It's important to note that rounding down means that there may be some leftover wood after making the 55 pieces. In this case, the remaining wood would be less than 13 feet long.

G(10)-73 which represents a wage gap of $73,000 in the year 1990.
Therefore, the correct option is G(10)-73, which represents a wage gap of 73% in the year 1990. This statement is false since the wage gap is 64% and not 73% in 1990.
a. We are given that G(x) = -0.01x²+x+65 represents the wage gap as a percent x years after 1980.
We are to find and interpret G(10).G(10) = -0.01(10)²+10+65

The wage gap 10 years after 1980 is 64%.
Therefore, the correct option is OA.G(10)-74, which represents a wage gap of 74% in the year 1990.
This statement is false since the wage gap is 64% and not 74% in 1990.
b. We are asked to determine the wage gap of the year 1990 from the given graph and function.
From the graph, we can see that the wage gap is approximately 65% in 1990.To confirm this using the function G, we will calculate G(10).G(10) = -0.01(10)²+10+65 = 64%
Option OB and OD are false since they don't represent the wage gap values for 1990. Thus, the correct option is OA G(10)-74, which represents a wage gap of 74% in the year 1990.

Evaluate the following expression when x=-5 and y=25.
(5|x|-y^(2))/(x)
vipengele sita vya kuzingatia katika uchanganuzi wa hadithi
When x = -5 and y = 25, the value of the expression is 120.
To evaluate the expression (5|x| - y²)/x when x = -5 and y = 25, replace x and y in the expression with their respective values.
Substitute the values:
(5|x| - y²)/x
= (5|(-5)| - 25²)/(-5)
Simplify the expression:
First, calculate the absolute value of -5:
|(-5)| = 5
Now, plug in the values:
(5|(-5)| - 25²) / (-5)
= (5 × 5 - 25²)/(-5)
Next, evaluate the square of 25:
25² = 25 × 25
= 625
Substitute the result:
(5 × 5 - 625)/(-5)
Now, perform the arithmetic operations inside the parentheses:
(25 - 625) / (-5)
= (-600) / (-5)
= 120
So, when x = -5 and y = 25, the expression evaluates to 120.
