Which of the following are not polynomials?
Answer:
A, B, D
Step-by-step explanation:
A polynomial is a 1 term or a sum of terms.
Each term is a number multiplied by 0 or more variables.
A term can never have a variable in the denominator or in any root. A term cannot have the logarithm of a variable or any trig function of a variable.
Answer: A, B, D
A system of equations is given.
Equation 1: 4x − 6y = 10
Equation 2: 9x + 2y = 7
Explain how to eliminate x in the system of equations.
Step-by-step explanation:
To eliminate x in the system of equations:
1. Multiply Equation 1 by 9 and multiply Equation 2 by -4, this gives:
Equation 1: 36x -54y = 90
Equation 2: -36x - 8y = -28
2. Add the two equations together to eliminate x:
(36x - 54y) + (-36x - 8y) = 90 - 28
Simplifying, we get:
-62y = 62
3. Solve for y:
y = -1
4. Substitute y = -1 into one of the original equations, say Equation 1:
4x - 6(-1) = 10
Simplifying, we get:
4x + 6 = 10
5. Solve for x:
4x = 4
x = 1
Therefore, the solution to the system of equations is x = 1 and y = -1. We can check that these values are correct by substituting them back into the original equations and verifying that they satisfy both equations.
find the domain of:
this
Answer:
The domain of a function is the set of all real numbers for which the function is defined. In this case, the function is defined when the denominator is not equal to zero. The denominator is equal to zero when x=1. Therefore, the domain of the function is all real numbers except for x=1.
In interval notation, the domain is written as
(-∞,1) ∪ (1,∞)

A carnival game has 150 rubber ducks floating in a pool. The person playing
the game takes out one duck and looks at it.
• If there's a red mark on the bottom of the duck, the person wins a small
prize.
Many ducks do not have a mark.
After 50 people have played the game, only 3 of them have won a small
prize.
Estimate the number of the 150 ducks that you think have red marks on
the bottom.
Answer:
Pretty sure it's 17 ducks.
The correct answer is based on the information given, we can estimate by probability that there are approximately 9 ducks with red marks on the bottom out of the 150 ducks in the pool.
To estimate the number of ducks with red marks on the bottom, we can use the information given: out of 50 people playing the game, only 3 have won a small prize.
We can assume that the probability of winning a small prize is the same for each player, and that each duck is equally likely to have a red mark.
If only 3 out of 50 people have won a small prize, we can estimate that the probability of winning is approximately 3/50.
Let's denote the number of ducks with red marks as "x." The probability of winning a small prize can be represented as x/150 (since there are 150 ducks in total).
Setting up the equation:
x/150 = 3/50
To solve for x, we can cross-multiply:
50x = 3 * 150
50x = 450
Dividing both sides by 50:
x = 9
Therefore, based on the information given, we can estimate by probability that there are approximately 9 ducks with red marks on the bottom out of the 150 ducks in the pool.

A cube and a net of the cube are shown. The edge length of the cube is labeled 5 centimeters. The net consists of 4 squares connected vertically, and 1 square is attached to the left of the third square and 1 square is attached to the right of the third square. One square in the net is labeled with a side labeled 5 centimeters.
The surface area of the cube is 1536 ft².
We have,
The cube can be seen as 6 square areas in the net.
So,
The surface area of the cube.
= 6 x area of one square surface.
Now,
Side = 16 ft
Area of one square surface.
= side²
= 16²
= 256 ft²
Now,
The surface area of the cube.
= 6 x area of one square surface.
= 6 x 256
= 1536 ft²

Using graphs, we can see that the point (4,2) can be a coordinate where y will represent x.
What are graphs?The graph is simply a structured representation of the data. The numerical information gathered through observation is referred to as data.
If there is just one value of y (output) for every value of x, the relationship between x and y is said to be a function (input).
In other words, there can only be one value of y for each value of x.
Determine each plotted point's coordinates first:
(-4,4)
(-2,3)
(0,1)
(2, -1)
(3,0)
The following point cannot have any of the x-coordinates of the displayed points, which are -4, -2, 0, 2, and 3.
Options include:
A (0,1) →The relationship cannot be regarded as a function at this stage as the x-coordinate zero already has a corresponding value of y.
B (2,2) →Although there is already a value of y for the location x=2, the relationship cannot be regarded as a function at this point.
C (3,4) →Although there is already a value of y for the location x=3, the relationship cannot be regarded as a function at this point.
D (4,2) → The relationship will still be regarded as a function even though there are no points on the graph with the coordinates x=4 displayed.
Therefore, option D (4,2) is the point where y will represent x.

\(P(0)=0.023(0)^3-0.289(0)^2+3.068(0)+55.170=55.17\)
A ball is thrown in the air from the top of a building. Its height, in meters above ground, as a function of time, in seconds, is given by h(t)= −4.9t^2+11t+7. How many seconds does it take to reach maximum height? Enter the answer with at least 3 decimal places.
Given statement solution is :- It takes approximately 1.122 seconds for the ball to reach its maximum height.
To find the time it takes for the ball to reach its maximum height, we need to determine the vertex of the parabolic function given by the equation h(t) = \(-4.9t^2 + 11t + 7.\)
The vertex of a parabola in the form y = \(ax^2 + bx\) + c is given by the formula t = -b / (2a).
Comparing the equation h(t) = \(-4.9t^2 + 11t + 7\) to the standard form, we have:
a = -4.9
b = 11
Using the formula for the vertex, we can calculate the time it takes to reach the maximum height:
t = -11 / (2 * -4.9)
t = -11 / -9.8
t ≈ 1.122
Therefore, it takes approximately 1.122 seconds for the ball to reach its maximum height.

The points A, B and C have position vectors a, b, c, referred to an origin O. i. Given that the point X lies on AB produced so that AB : BX = 2 : 1, find x, the position vector of X, in terms of a and b. ii. If Y lies on BC, between B and C so that BY : Y C = 1 : 3, find y, the position vector of Y, in terms of a and b iii. Given that Z is the midpoint of AC, Calculate the ratio XY : Y Z.
i. The position vector of X is 2b - a.
ii. The position vector of Y is (3b + c)/4.
iii. The ratio XY : Y Z is \(|(2b - a) - ((3b + c)/4)|/|((3b + c)/4) - (a + c)/2|\). Simplifying this expression will give us the final ratio.
i. To find the position vector x of point X, we can use the concept of vector addition. Since AB : BX = 2 : 1, we can express AB as a vector from A to B, which is given by (b - a). To find BX, we can use the fact that BX is twice as long as AB, so BX = 2 * (b - a). Adding this to the vector AB will give us the position vector of X: x = a + 2 * (b - a) = 2b - a.
ii. Similar to the previous part, we can express BC as a vector from B to C, which is given by (c - b). Since BY : YC = 1 : 3, we can find BY by dividing the vector BC into four equal parts and taking one part, so BY = (1/4) * (c - b). Adding this to the vector BY will give us the position vector of Y: y = b + (1/4) * (c - b) = (3b + c)/4.
iii. Z is the midpoint of AC, so we can find Z by taking the average of the vectors a and c: z = (a + c)/2. The ratio XY : YZ can be calculated by finding the lengths of the vectors XY and YZ and taking their ratio. Since XY = |x - y| and YZ = |y - z|, we have XY : YZ = |x - y|/|y - z|. Plugging in the values of x, y, and z we found earlier, we get XY : YZ =\(|(2b - a) - ((3b + c)/4)|/|((3b + c)/4) - (a + c)/2|\).

Define rate of interestThe rate of interest, also known as the interest rate, is the percentage amount charged by a lender or financial institution for the use of borrowed money or for the extension of credit. It is the cost of borrowing money, typically expressed as an annual percentage of the amount borrowed or owed.
