Is △RWS ~ △QWT?
yes
no
Answer: Yes ΔRWS≈ΔQWT.
Step-by-step explanation:
We know that when two chords intersect each other inside a circle, the products of their segments are equal.
Therefore, [tex]QW\times WS=TW\times RW\\\Rightarrow\frac{QW}{RW}=\frac{TW}{WS}[/tex]
Now in triangle QWT and triangle RWS
∠QWT=∠RWS [Vertically opposite angles]
[tex]\frac{QW}{RW}=\frac{TW}{WS}[/tex]
Therefore, By SAS similarity rule
ΔRWS≈ΔQWT
Therefore, yes ΔRWS≈ΔQWT.

Your total bill at a restaurant is $24.89 you were very pleased with your service so you decide to leave a 20% tip what is the amount of the tip you will leave your waiter
The amount of tip I would leave for the waiter is $24.89
A tip is a form of payment that is given to someone who renders a service. The amount of tip that was given is a percentage of the total bill at the restaurant.
The value of the tip can be determined by multiplying the percentage of tip by the total bill at the restaurant
Value of the tip = percentage tip x total bill at the restaurant
20% x $24.89
0.2 x $24.89 = $4.98

When multiplying integers, if there is an odd number of negative factors, then the product is?
Answer:
The product of an odd number of negative factors is negative.
Step-by-step explanation:
The factor -1 can be factored from any negative number. Then the product of some number of negative numbers is the product of that number of positive numbers and -1 raised to that power.
An even power of -1 is 1.
An odd power of -1 is -1. So, the product of an odd number of negative factors is negative.

This is helpful to remember when considering the solutions to polynomial inequalities. Once the factored form of the polynomial is found, the solution will depend on the signs of the factors. For example, consider ...
(x +4)(x -2)(x -3) < 0
The zeros of these factors are -4, 2, 3. At each of these values of x, the sign of one of the factors will change. For x<-4, all three factors are negative, so the inequality is true. For -4<x<2, only two of the factors are negative, so the inequality is false. For 2<x<3, one of the factors is negative, so the inequality is again true. For 3<x, all factors are positive, so the inequality is false. Then the solution is (x < -4) ∪ (2 < x < 3).

Line segment ab has a length of 4 units. it is translated 1 unit to the right on a coordinate plane to obtain line segment a prime b prime. what is the length of a prime b prime? 1 unit 4 units 5 units 6 units
Answer:
The length of A'B' is 4 unit.
Step-by-step explanation:
Translation is a rigid transformation in which a figure or a line segment is shifted or moved without changing its shape and size,
That is, if the measurement of segment AB is 4 unit then after translation by any factor its measurement will not change,
So, the measurement of segment A'B' would be 4 unit.
Verification :
Let the coordinates of A and B are [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] respectively,
Also, the rule of translation 1 unit right is,
[tex](x,y)\rightarrow (x+1, y)[/tex]
By the distance formula,
The measure of segment AB = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Thus, if A'B' is the transformed segment of segment AB,
Then, coordinates of A' and B' are [tex](x_1+1, y_1)[/tex] and [tex](x_2+1, y_2)[/tex]
So, the measure of segment A'B' = [tex]\sqrt{(x_2+1-x_1-1)^2+(y_2-y_1)^2}=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Hence, the measure of AB = measure of A'B'

To graph the solution set of an inequality with two variables, first graph the boundary with a dashed or solid line depending on the inequality. If given a strict inequality, use a dashed line for the boundary. If given an inclusive inequality, use a solid line. Next, choose a test point not on the boundary. If the test point solves the inequality, then shade the region that contains it; otherwise, shade the opposite side.

Answer : The given polynomial equation can have 0,2 or 4 complex roots.
Explanation:-
Given polynomial equation is [tex]3x^5-2x+1=0[/tex] which is a polynomial of degree 5.
We know that the complex roots always occur in pair ,therefore the number of complex roots in any polynomial must be an even number but less than equal to the degree of polynomial.
Thus, the given polynomial equation has 4 complex roots.
Answer:
The polynomial equation have 4 complex roots.
Step-by-step explanation:
We are given a polynomial equation as:
[tex]3x^5-2x+1=0[/tex]
clearly the polynomial equation is a equation of degree 5 hence, the polynomial equation has atmost 5 roots.
Now we find the roots of the equation by it's graph.
we could clearly see that the graph ofthe function passes through the point (-1,0). hence -1 is the root of the polynomial equation, other than this point the graph does not touches or pass through the x-axis.
Hence, the other four roots of the polynomial equation are complex.
Hence, the polynomial equation has 4 complex roots.

The path of the rock can be modeled by the equation y = -0.005x 2 + 0.41x - 5.1, where x is the horizontal distance of the rock, in feet, from Landon and y is the height, in feet, of the rock above the ground. How far horizontally from Landon will the rock land?
A ferris wheel is drawn on a coordinate plane so that the first car is located at the point (0,40). What are the coordinates of the first car after a rotation of 270 degrees° counterclockwise about the origin?
After a 270-degree counterclockwise rotation, the first car on the ferris wheel originally located at (0, 40) will be at (40, 0).
Explanation:If the first car of a ferris wheel is located at the point (0, 40) on a coordinate plane and undergoes a rotation of 270 degrees counterclockwise about the origin, the new coordinates of the first car can be determined by applying a rotation transformation. To perform a 270-degree counterclockwise rotation, we rotate the point 90 degrees clockwise. This equivalent action simplifies the calculation, as rotating (0, 40) 90 degrees clockwise results in the point moving to (40, 0). Therefore, after a 270-degree counterclockwise rotation (which is equivalent to a 90-degree clockwise rotation), the new coordinates of the first car on the ferris wheel are (40, 0).
You deposit $5000 in an account earning 7.5% simple interest. How long will it take for the balance of the account to be $6500?
Final answer:
It will take 4 years for the balance of an account to grow from $5000 to $6500 at a 7.5% simple interest rate. The formula for simple interest I = P × r × t is used, and after rearranging to solve for t, we find t = 4 years.
Explanation:
To calculate how long it will take for the balance of an account to reach a certain amount with simple interest, we can use the formula for simple interest: I = P × r × t, where I is the interest earned, P is the principal amount (initial deposit), r is the annual interest rate, and t is the time in years. In this case, we want to find out when the account balance will be $6500 after depositing $5000. The total interest earned to reach $6500 will be $6500 - $5000 = $1500.
The given annual interest rate is 7.5% (or 0.075 when converted to decimal form). We will rearrange the simple interest formula to solve for t:
t = I / (P × r)
Now, substituting the given values:
t = $1500 / ($5000 × 0.075)
t = $1500 / $375
t = 4 years
Therefore, it will take 4 years for the balance of the account to be $6500 at a 7.5% simple interest rate.
Kim's class voted on a location for a field trip. • 5/12 of the class voted for the museum. • 5/24 of the class voted for the zoo. The rest of the class voted for the nature park. What fraction of the class voted for the nature park? The nature park received of the class votes.
Final answer:
By adding the fractions of votes for the museum (5/12) and zoo (5/24), converting them to a common denominator, and subtracting from the whole, we find that 3/8 of the class voted for the nature park.
Explanation:
To determine what fraction of the class voted for the nature park, we first need to add up the fractions of the class that voted for the museum and the zoo, and then subtract that sum from the whole class, which is represented as 1 (or 12/12). Since 5/12 of the class voted for the museum and 5/24 of the class voted for the zoo, we need to find a common denominator to add these fractions together. The lowest common denominator for 12 and 24 is 24.
First, we convert 5/12 to a fraction with a denominator of 24, which would be 10/24 (since 5 × 2 = 10 and 12 × 2 = 24). Now we can add the two fractions:
10/24 (votes for the museum)
5/24 (votes for the zoo)
Therefore, 10/24 + 5/24 = 15/24. After that, we subtract the sum from the whole to find out what fraction voted for the nature park:
12/12 - 15/24 = 24/24 - 15/24 = 9/24.
Hence, 9/24 of the class voted for the nature park. However, we can simplify 9/24 by dividing the numerator and the denominator by their greatest common divisor, which is 3, giving us 3/8.
Therefore, 3/8 of the class voted for the nature park.

Which equation is a trigonometric identity?
In a class of 80 students, 42 received a grade of
a. what fraction of the class did not receive an a? reduce to the lowest terms.
42 received an A
so 40-42 = 38 did not
the fraction would be 38/80, divide both numbers by 2
38/80 reduces to 19/40 did not receive an A
Out of 80 students, 38 did not receive an A, resulting in the fraction who did not receive an A being 19/40 after simplifying.
Explanation:In a class of 80 students, if 42 received a grade of A, then the number of students who did not receive an A is the total number of students minus the number who did receive an A. So, 80 students − 42 students = 38 students. The fraction of the class that did not receive an A is 38 out of 80, which can be simplified by dividing both the numerator and the denominator by their greatest common factor, which is 2.
Therefore, the reduced fraction is 19/40.
The fraction of the class that did not receive an A is 19/40 which, if we converted into a percentage, would be 47.5%.
