Choose the polynomial that is written in standard form 7x^5+8x^8+27x
Don’t need the answer just couldn’t find the question lol so the answer is 3
Answers
Answer: Option d: -3*x^4*y + 2*x^2*y^2 + 5*y^3
Step-by-step explanation:
In standard form, the first term of the polynomial must be the term with the highest degree and on each subsequent term the degree decreases. In the case of two variables, the degree is equal to the sum of the exponents.
Then the correct option is d.
Where the degree of the first term is (4 + 1) = 5
The degree of the second term is (2 + 2) = 4
The degree of the third therm is 3.
We can see that the degree decreases as the term number increases, then the polynomial written in standard form is:
-3*x^4*y + 2*x^2*y^2 + 5*y^3

First, let's remember the exact value of the sine and cosine of 45°. If we have a right triangle with sides 1 and hypotenuse sqrt(2), then we have:
Then, we have the following values for the sine and cosine of 45°:
\(\begin{gathered} \sin (45)=\frac{\text{opposite side}}{hypotenuse}=\frac{1}{\sqrt[]{2}} \\ \cos (45)=\frac{\text{adjacent side}}{hypotenuse}=\frac{1}{\sqrt[]{2}} \end{gathered}\)We can find the values of x and y using the trigonometric functions sine and cosine:
\(\begin{gathered} \sin (45)=\frac{\text{opposite side}}{hypotenuse} \\ \Rightarrow\sin (45)=\frac{x}{24} \\ \Rightarrow\frac{1}{\sqrt[]{2}}\cdot24=x \\ \Rightarrow x=(\frac{24}{\sqrt[]{2}})\cdot(\frac{\sqrt[]{2}}{\sqrt[]{2}})=\frac{24\cdot\sqrt[]{2}}{2}=12\sqrt[]{2} \\ \cos (45)=\frac{\text{adjacent side}}{hypotenuse} \\ \Rightarrow\cos (45)=\frac{y}{24} \\ \Rightarrow y=24\cdot(\frac{1}{\sqrt[]{2}})=12\sqrt[]{2} \end{gathered}\)therefore, the values for x and y are:
\(\begin{gathered} x=12\sqrt[]{2} \\ y=12\sqrt[]{2} \end{gathered}\)

The boat rental company gave a rowing team a discount of $10 off for every
4 days of rental. The team rented a boat for 12 days. Their coach paid 35%
of the total discounted rental cost. The remaining rental cost was divided
equally among the 16 team members.
Determine the total cost for the team to rent a boat,
Determine the cost per team member
Answers
Part a: total discounted rental cost for the boat = $690.
Part b: cost per team member = $32.34
Explain about the linear equation?A two-variable linear equation can be thought of as a linear relationship involving x and y, or two variables whose values rely on each other (often y and x) (usually x).
From the graph:
Part a: Rental cost for boat for 3 days is 180.
For 1 day = 180/3 = 60.
So,
Total cost for the team to rent a boat for 12 days:
total discounted rental cost = 12*60 - 12/4 *10
total discounted rental cost = $720 - $30
total discounted rental cost = $690
Part b: cost per team member
total discounted rental cost = 35% paid by coach.
remaining 75% is equally divided in all 16 team members.
Then,
cost per team member = 0.75*690 / 16
cost per team member = $32.34

⦁ Calculate the residuals for your scatterplot in step 2d.
⦁ Create a residual plot for your data.
⦁ Does your residual plot show that the linear model from the regression calculator is a good model? Explain your reasoning.
Answers
The residuals of the linear regression equation are 0.329, -0.346, 0.064, -0.326, 0.049, -0.286, -0.161, 0.214, 0.429 and 0.059
How to determine the residuals?The regression equation is given as:
y = 0.005x + 3.111
Next, we calculate the predicted values (y) at the corresponding x values.
So, we have:
y = 0.005 * 4 + 3.111 = 3.131
y = 0.005 * 3 + 3.111 = 3.126
y = 0.005 * 5 + 3.111 = 3.136
y = 0.005 * 3 + 3.111 = 3.126
y = 0.005 * 8 + 3.111 = 3.151
y = 0.005 * 15 + 3.111 = 3.186
y = 0.005 * 10 + 3.111 = 3.161
y = 0.005 * 15 + 3.111 = 3.186
y = 0.005 * 6 + 3.111 = 3.141
y = 0.005 * 6 + 3.111 = 3.141
The residuals are then calculated using:
Residual = Actual value - Predicted value
So, we have:
y = 3.46 - 3.131 = 0.329
y = 2.78 - 3.126 = -0.346
y = 3.2 - 3.136 = 0.064
y = 2.8 - 3.126 = -0.326
y = 3.2 - 3.151 = 0.049
y = 2.9 - 3.186 = -0.286
y = 3 - 3.161 = --0.161
y = 3.4 - 3.186 = 0.214
y = 3.57 - 3.141 = 0.429
y = 3.2 - 3.141 = 0.059
Hence, the residuals of the linear regression equation are 0.329, -0.346, 0.064, -0.326, 0.049, -0.286, -0.161, 0.214, 0.429 and 0.059

Step-by-step explanation:
So, first lets start of with what supplement means? Well, supplement of angle 1 really just means that angle 1 and 3 are supplementary angles.
What are supplementary angles?
They are angles that can be added up to 180 degrees.
Dont get these confused with complementary angles, which add up to 90 degrees.
So, now that we know this, lets solve for our angle 3.
We can use this to solve:
angle 1 + angle 3 = 180 degrees.
Now, we know that angle 3 is 64 degrees. Lets inlcude this in our equation:
angle 1 + 64 degrees = 180 degrees.
Now lets solve for angle 1:
angle 1 = 116
This is because we subtracted 64 from both sides to get angle 1 alone, and 180-64=116.
Now, lets look at the answers
A = 64 degrees
B = 116 degrees
C = 26 degrees
D = 128 degrees.
Now we know it must be B, since that answer is 116 degrees.

Answer:
500 + 100m = 1000 + 50m
Step-by-step explanation:
In order to form an equation we need atleast on variable which in this scenario would be the number of months (m). We can say that we know that sooner or later their savings will equal. Therefore, we can create the following equations for each of their savings progress which are equal to one another...
500 + 100m = 1000 + 50m
This equation if solved would give us the value of 10 for the variable m, meaning that their savings will equal in 10 months. To find out how much each will have in 10 months we can simply grab one half of the equation and substitute 10 for m
500 + 100(10) = x
500 + 1000 = x
1500 = x
Finally, we can see that after 10 months they would both have $1500 saved up.

Type your response in the box below.
$$
Answers
The resulting equation after multiplying the first equation by 2 and subtracting the second equation is:
-5y = -375
1. Given equations:
- x + 3y = 350 (Equation 1)
- 2x + 4y = 625 (Equation 2)
2. Multiply Equation 1 by 2:
- 2(x + 3y) = 2(350)
- 2x + 6y = 700 (Equation 3)
3. Subtract Equation 2 from Equation 3:
- (2x + 6y) - (2x + 4y) = 700 - 625
- 2x - 2x + 6y - 4y = 75
- 2y = 75
4. Simplify Equation 4:
-2y = 75
5. To isolate the variable y, divide both sides of Equation 5 by -2:
y = 75 / -2
y = -37.5
6. Therefore, the resulting equation is:
-5y = -375

An airline ticket costs $220. Jameson receives a 10% discount on the ticket but is also charged an 8.25% service fee. what is the discounted price of the ticket? What is the total cost of the ticket with the discount and service fee?
Answers
The discounted price of the ticket is $198.
The total cost of the ticket with the discount and service fee is $214.33.
What is a percentage?A percentage is a ratio or number that may be expressed as a fraction of 100. Moreover, it is denoted by the sign "%."
Given:
The cost of a ticket on an airline is $220.
And Jameson receives a discount of 10%.
To find the discounted price:
The discounted price = 220 - 220 x 10 / 100
The discounted price = $198.
And the service charge is 8.25%.
So, the amount of service charge,
= 198 x 8.25/100
= 16.33
The total cost of a ticket = $198 + $16.33 = $214.33
Therefore, the cost is $214.33.
