Divide the following polynomial, then place the answer in the proper location on the grid. Write your answer in order of descending powers of x.
(a^2n - a^n - 6) ÷ (a^n + 8)
Answers
The correct answer for dividing [tex](a^{2n} - a^n - 6) by (a^n + 8)[/tex] is indeed:
[tex](a^n - 9) + (-78)/(a^n + 8).[/tex]
Let's divide the given polynomials:
[tex]\frac{a^{2n -a^n -6}}{a^n +8}[/tex]
Here's the breakdown of the solution:
Factoring: We can factor the numerator [tex](a^{2n} - a^n - 6)[/tex] using difference of squares:
[tex](a^{2n} - a^n - 6) = (a^n)^2 - (a^n) - 6 = (a^n + 2)(a^n - 3)[/tex]
Division: Now, we can divide the factored numerator by the denominator:
[tex][(a^n + 2)(a^n - 3)] / (a^n + 8) = (a^n + 2) - [(a^n + 8) * (a^n - 3)] / (a^n + 8) = (a^n + 2) - (a^n - 3) = a^n - 9[/tex]
Remainder: Since the degree of the numerator is less than the degree of the denominator, we get a non-zero remainder.
This remainder is obtained by dividing the constant term (-6) in the numerator by the constant term (8) in the denominator, resulting in [tex]-78/(a^n + 8).[/tex]
Therefore, the final answer is [tex](a^n - 9) + (-78)/(a^n + 8)[/tex], with a quotient of [tex](a^n - 9)[/tex] and a non-zero remainder of [tex](-78)/(a^n + 8).[/tex]

The height y (in feet) of a ball thrown by a child is
y = − 1/14x^2 + 6 x + 3
where x is the horizontal distance in feet from the point at which the ball is thrown.
How high is the ball when it leaves the child's hand? (Hint: Find y when x = 0)Your answer is y=
(b) What is the maximum height of the ball?(c) How far from the child does the ball strike the ground?
Answers
Answer:
3 ft129 ft84.5 ftStep-by-step explanation:
The given equation,
[tex]y=-\dfrac{1}{14}x^2+6x+3[/tex]
where,
x is the horizontal distance in feet and
y is the height of the ball in feet.
How high is the ball when it leaves the child's hand.
At the beginning when the ball leaves the hand of the child, the horizontal distance was 0, so putting x=0 we can get the height of the ball.
[tex]y_0=-\dfrac{1}{14}(0)^2+6(0)+3=3\ ft[/tex]
What is the maximum height of the ball.
As the quadratic function has negative leading coefficient, so it will open downwards and at the vertex we will get the maximum value of the function.
The coordinates of vertex are,
[tex]\left(-\dfrac{b}{2a},f\left(-\dfrac{b}{2a}\right)\right)[/tex]
Putting the values,
[tex]=\left(-\dfrac{6}{2\times -\frac{1}{14}},f\left(-\dfrac{6}{2\times -\frac{1}{14}}\right)\right)[/tex]
[tex]=\left(42,f\left(42\right)\right)[/tex]
Now,
[tex]y_{max}=f(42)=-\dfrac{1}{14}(42)^2+6(42)+3= 129\ ft[/tex]
How far from the child does the ball strike the ground.
At the end i.e when the ball touches the ground, the height of the ball is 0. So putting the value of y=0, in the equation,
[tex]\Rightarrow 0=-\dfrac{1}{14}x^2+6x+3[/tex]
[tex]\Rightarrow -\dfrac{1}{14}x^2+6x+3=0[/tex]
[tex]\Rightarrow -x^2+6x(14)+3(14)=0[/tex]
[tex]\Rightarrow -x^2+84x+42=0[/tex]
Solving the quadratic equation, we get
[tex]\Rightarrow x=-0.497,84.5[/tex]
As distance can not be negative, so only considering positive value,
[tex]x=84.5\ ft[/tex]
The ball is 3 feet high when it leaves the child's hand. The maximum height of the ball is 251 feet. The ball strikes the ground approximately 0.4 feet away from the child.
Explanation:To find how high the ball is when it leaves the child's hand, we need to calculate the height when x = 0. Plugging in x = 0 into the equation, we get y = -1/14(0)^2 + 6(0) + 3 = 3 feet. Therefore, the ball is 3 feet high when it leaves the child's hand.
To find the maximum height of the ball, we need to determine the vertex of the quadratic equation. The formula for the x-coordinate of the vertex of a quadratic equation in the form y = ax^2 + bx + c is given by x = -b/2a. In this case, the x-coordinate is x = -6/(-1/14) = 84 feet. Plugging x = 84 into the equation, we find y = -1/14(84)^2 + 6(84) + 3 = 251 feet. Therefore, the maximum height of the ball is 251 feet.
To find how far from the child the ball strikes the ground, we need to find the x-intercepts of the equation, which represent the points where y = 0. Setting y to 0 and solving for x, we get: -1/14x^2 + 6x + 3 = 0. Using the quadratic formula, we find two values for x: x = 14(6 ± √187) / (-2), which simplifies to approximately x = -0.4 and x = 85.4. The ball strikes the ground approximately 0.4 feet away from the child.

A square foot wall of space needs 1/8 quart of paint. Terrence has 7 quarts of paint, but uses 2 quarts to paint a pipe. How many square feet of wall can he paint with the rest of the paint
Answers
Answer:
40 square feet.
Step-by-step explanation:
We have been given that a square foot wall of space needs 1/8 quart of paint. Terrence has 7 quarts of paint, but uses 2 quarts to paint a pipe.
The amount of paint that left will be 5 quarts (7-2=5).
To find the area of wall that can be painted with the rest of paint, we will divide amount of left paint by the amount used to paint one square foot of wall.
[tex]\text{The number of square feet that can be painted with rest of paint}=5\div \frac{1}{8}[/tex]
Dividing a number by a fraction is same as multiplying the number by the reciprocal of fraction.
[tex]\text{The number of square feet that can be painted with rest of paint}=5\times \frac{8}{1}[/tex]
[tex]\text{The number of square feet that can be painted with rest of paint}=5\times 8=40[/tex]
Therefore, 40 square feet of wall can be painted with the rest of the paint.
Terrence can paint 40 square feet of wall with the rest of the paint.
Explanation:To find out how many square feet of wall Terrence can paint with the rest of the paint, we need to subtract the amount of paint he used to paint the pipe from the total amount of paint he has. Terrence has 7 quarts of paint and used 2 quarts to paint the pipe, so he has 7 - 2 = 5 quarts of paint left. Since 1/8 quart of paint is needed for 1 square foot of wall, we can find out how many square feet of wall Terrence can paint by dividing the amount of paint he has left by the amount of paint needed for 1 square foot:
Number of square feet of wall Terrence can paint = (5 quarts) / (1/8 quart per square foot) = (5 quarts) × (8/1) square feet per quart = 40 square feet.

The original price of the water skis was $200. They are on sale for $150. What is the percent of discount?
Answers
Answer:
25%
Step-by-step explanation:
percent discount = [tex]\frac{discount}{original}[/tex] × 100%
discount = $200 - $150 = $50
percent discount = [tex]\frac{50}{200}[/tex] × 100% = 25%
Final answer:
To find the percent of discount, calculate the difference between the original and sale prices ($50), divide this by the original price, and multiply by 100 to get a 25% discount.
Explanation:
To calculate the percent of discount given on the water skis, you need to determine the difference between the original price and the sale price, and then find what percentage that difference is of the original price.
First, subtract the sale price from the original price to find the amount of discount:
Discount Amount = Original Price - Sale Price
Discount Amount = $200 - $150 = $50
Next, divide the discount amount by the original price and multiply by 100 to get the discount percentage:
Discount Percentage = (Discount Amount / Original Price) × 100
Discount Percentage = ($50 / $200) × 100 = 25%
Therefore, the percent of discount on the water skis is 25%.

Answers
Answer:
The answers are as follows:
2 Green = 25%
2 Red = 4%
1 Black 1 Green = 15%
1 Green 1 Red = 10%
Step-by-step explanation:
In order to find any of these, we first have to find the probability of pulling any of them individually. To find that, we simply divide the number of marbles by the total in the jar.
Green = 5/10 = 50%
Black = 3/10 = 30%
Red = 2/10 = 20%
Now to find any combination, simply multiply the percentages together. For instance, for 1 black and 1 green, multiply those percentages together.
Black * Green
30% * 50% = 15%
You can do this for any number of combinations
Chapman’s brickyard sells bricks and blocks. A brick costs $0.38 and a block costs $1.56. The brickyard filled a $24.80 order, which contained 28 items
a. Write a system of equations that can be used to find the number of bricks and blocks in the order.
b. How many blocks were in the order?
Answers
Answer:
(a) A system of equations:
[tex]0.38x+1.56y = 24.80[/tex]
[tex]x+y = 28[/tex]
(b) Number of blocks were in the order is, 12
Step-by-step explanation:
(a)
Let x represents the number of bricks and y represents the number of blocks.
As per the given statement:
A bricks costs $ 0.38 and a block costs $1.56.
Total bricks costs = 0.38x and total block costs = 1.56y
The brickyard filled $24.80 order.
⇒ [tex]0.38x+1.56y = 24.80[/tex] ......[1]
Since, it contained 28 items.
⇒[tex]x+y = 28[/tex] ....[2]
Multiply equation [2] both sides by 0.38 we have;
[tex]0.38(x+y) = 0.38 \times 28[/tex]
Using distributive property: [tex]a\cdot (b+c) = a\cdot b + a\cdot c[/tex]
0.38x +0.38 y = 10.64 ......[3]
Subtract equation [3] from [1] to get x eliminated ;
[tex]0.38x+1.56y -0.38x -0.38y= 24.80 - 10.64[/tex]
Combine like terms;
1.18y =14.16
Divide both sides by 1.18 we have;
[tex]\frac{1.18y}{1.18} = \frac{14.16}{1.18}[/tex]
Simplify:
[tex]y = 12[/tex]
Substitutes this y value in equation [2] to solve for x;
x + 12= 28
Subtract 12 from both sides we get;
x +12-12 =28-12
Simplify:
x = 16
Therefore, a system of equations that can be used to find the number of bricks and the number of blocks in the order:
[tex]0.38x+1.56y = 24.80[/tex]
[tex]x+y = 28[/tex]
(b)
The number of blocks are in order(y), is 12.

The zeros of the function are the x-intercepts. If the x-intercepts touch but do not cross then the intercepts have an even multiplicity like 2, 4, 6, etc. If the x-intercepts cross over then they have an odd multiplicity. Degree is the exponent or multiplicity of each zero. Therefore if we know the multiplicity of each zero we can add them together to find or make an educated guess for the degree of the entire polynomial. The shape of the graph tells us what type of polynomial. Odd degrees have a backwards S shape. Even degrees have a W shape. The shape can even tell us the if the equation has a positive or negative leading coefficient. Upside down W or an M shape is negative.

what is the measure of xwz
Answers
Answer:

Step-by-step explanation:
The measure of Angles XWZ is 120 degrees.
To find the measure of XWZ, we need to consider the relationships between different angles in the diagram.
First, we know that angle XYZ is 50 degrees.
Since XY and YZ are tangent to circle O, angle XYZ is equal to angle OXZ. Therefore, angle OXZ is also 50 degrees.
Next, we know that the circumference of circle O is 120 degrees.
A full revolution around a circle is 360 degrees, so the ratio of the circumference of circle O to a full revolution is 120/360 = 1/3.
Since angle OXZ is one-third of a full revolution, it will be equal to one-third of 360 degrees, which is 120 degrees. So, the measure of angle XWZ is 120 degrees.
