Which of the following quadratics would have the roots of 1+ or 1- ^2.
The quadratic equation for the given roots is x²-2x-1=0. Therefore, option 4 is the correct answer.
What is the solution of a quadratic equation?The solutions to the quadratic equation are the values of the unknown variable x, which satisfy the equation. These solutions are called roots or zeros of quadratic equations. The roots of any polynomial are the solutions for the given equation.
The roots of the quadratic equation are 1±√2.
Here, x=1+√2 and x=1-√2
x-1-√2=0 and x-1+√2=0
Now, (x-1-√2)(x-1+√2)=0
= x(x-1+√2)-1(x-1+√2)-√2(x-1+√2)=0
= x²-x+√2x-x+1-√2-√2x+√2-2=0
= x²-2x-1=0
Therefore, option 4 is the correct answer.

A new van is priced at $19,500. If the buyer chooses to finance, they will pay $5,000 as a down payment and $375 per month. After how many months will the buyer have paid more that $10,000 toward the van?
A. 19,500 — 375x < 10,000
B. 5,000x + 375 > 10,000
C. 19,500 — 5000x > 10,000
D. 5,000 + 375 > 10,000
The inequality that represents the situation is . 5,000x + 375 > 10,000
(option b)
What is the the inequality?
The inequality that can be used to determine after how many months he would have paid more than $10,000 has this form:
down payment + (monthly payment x number of months) > $10,000
$5,000 + ($375 x m) > $10,000
$5,000 + $375m > $10,000
In order to determine the value of m, take the following steps:
Combine similar terms together:
375m > 10,000 - 5,000
Add similar terms together:
375m > $5000
Divide both sides of the equation by 375
m > 5000 / 375
m > 13.3 days

a) Measure the bearing of B from A = 030
b) Measure the bearing of A from B = 210
What is bearing angle?The term bearing is used in the navigation. The bearing is the horizontal angle which is made between the direction of an object to the another object.
This angle is measure in the clockwise direction from the north direction.
To measure bearing of two cities:
Draw a straight line between point A and B upward. Now draw 2 lines vertically up going through both points as shown in attached image. Now measure the angle between the vertical line and the diagonal line. It's 030.
Hence, measure the bearing of B from A is 030.
To measure the bearing of A from B add 180 to the 030.
we get 210.

The members of the city cultural center have decided to put on a play once a night for a week. Their auditorium holds 600 people. By selling tickets, the members would like to raise $3,900 every night to cover all expenses. Let x represent the number of adult tickets sold at $8.50. Let y represent the number of student tickets sold at $5.50 each. If all 600 seats are filled for a performance, how many of each type of ticket must have been sold for the members to raise exactly $3,900? At one performance there were times as many student tickets sold as adult tickets. If there were 400 tickets sold at that performance, how much below the goal of $3,900 did ticket sales fall?
By using simultaneous linear equation, it can be calculated that 200 adult tickets and 400 student tickets were sold and the ticket sale falls $1320 below the goal of $3300.
What is simultaneous linear equation?Equation shows the equality between two algebraic expressions by connecting the two algebraic expressions by an equal to sign.
A one degree equation is known as linear equation. Two or more linear equations, which can be solved together to obtain common solution are known as simultaneous linear equation.
The simultaneous linear equation needs to be solved
Let d represents the number of adult tickets and s represents the number of student tickets
Their auditorium holds 600 people
d + s = 600 ..... (1)
Price of adult ticket = $7.50
Price of student ticket = $4.50
Total price = $(7.50d + 4.50s)
Therefore,
7.50d + 4.50s = 3300
5d + 3s = 2200 ..... (2)
Multiplying (1) by 3
3d + 3s = 1800.... (3)
Subtracting (3) from (2)
2d = 400
d = 200
Putting the value of d in (1)
200 + s = 600
s = 600 - 200
s = 400
Now, Total tickets sold = d + 2d = 3d
d = 120
s = 240
Number of student ticket sold = 240
Number of adult ticket sold = 120
Total cost = 240 4.50 + 120 7.50
= $1980
Fall in ticket sale = $(3300 - 1980) = $1320

The sum of the present ages of Kathy and Samantha is 60 years. In 8 years, Kathy will be 5 years older than 3 times as old as Samantha was 3 years ago. How old are they now? Write it in a equation
Answer:
Kathy is 48 years old and Samantha is 12.
Step-by-step explanation:
This is a challenging question that requires some interpretation. Let K and S stand for the current ages of Kathy and Samatha.
We are told that: K+S = 60
And, in 8 years: K+8 and S+8
"Kathy will be 5 years older than 3 times as old as Samantha was 3 years ago" ["3 years ago:" from now or in 8 years. I'll interpret it as from now, or (S-3)]
(K+8) = 3(S+8-3)+5 ["5 years older than 3 times as old as Samantha was 3 years ago"]
(K+8) = 3(S+5)+5
K+8 = 3S+20
K = 3S+12
---
Rearrange the firts equation to isolate K
K = 60-S
Now use this definition of K in the previous equation:
K = 3S+12
60-S = 3S+12
4S = 48
S = 12
K+S = 60
K+12 = 60
K = 48
=====
CHECK
Does K + S = 60? 48+12 = 60 YES
In 8 years, will Kathy will be 5 years older than 3 times as old as Samantha was 3 years ago?
K = 48+8 = 56
S = 12+8 = 20
Three years ago S was 9.
(K+8) = 3(S+8-3)+5
(K+8) = 3(12+8-3)+5
K + 8 = 3(17)+5
K = 48

Kathy is 48 years old and Samantha is 12.
A hot air ballon is hovering 104 meters above the ground and begins to assend at a rate of 11 meters per second. Let
y be the height of the balloon in meters x seconds after it begins to assend.
Write an equation in slope-intercept form that models the height of the balloon.
How high is the balloon after 19 seconds?
Answer: The height of the balloon in meters x seconds after it begins to ascend can be represented by the equation y = mx + b, where m is the slope (the rate of change in height) and b is the y-intercept (the initial height of the balloon).
Given that the balloon is hovering 104 meters above the ground and begins to ascend at a rate of 11 meters per second, we can substitute these values into the equation:
y = 11x + 104
This equation is in slope-intercept form, the slope (m) is 11 and the y-intercept (b) is 104. This equation represents the height of the balloon in meters x seconds after it begins to ascend.
To find the height of the balloon after 19 seconds, we can substitute x = 19 into the equation:
y = 11(19) + 104 = 209 meters
So the hot air balloon is 209 meters high after 19 seconds.

find the derivative by first principle rule f(x)=3÷x+2
Answer:
The derivative of f(x) = 3 ÷ x + 2 is f'(x) = -3 ÷ (x+2)².
Step-by-step explanation:
This is found by using the first principle method of differentiation, which states that the derivative of a function is the rate of change of the function with respect to the indepedent variable. In other words, the derivative of a function measures how much the output of the function changes with respect to a small change in the input.
To find the derivative of f(x) = 3 ÷ x + 2, we start by taking the limit as h approaches 0 of the difference quotient (f(x + h) - f(x)) ÷ h.
The difference quotient is (3 ÷ (x + h + 2) - 3 ÷ (x + 2)) ÷ h. Simplified, this becomes 3h ÷ (x + h + 2)(x + 2).
When h approaches 0, the difference quotient becomes 3 ÷ (x + 2)², which is the derivative of f(x).

When an object is dropped from above the ground the equation Y= 16x ^2 represents the number of feet y that the object falls in X seconds until it hits the ground a student claims that Y is not a function of X because X is squared is the student correct
The student is not correct. Y = 16x^2 is a function of X.
A function is a mathematical relationship between two variables, where each value of the independent variable (in this case, X) corresponds to exactly one value of the dependent variable (in this case, Y). The equation Y = 16x^2 satisfies this definition.
The fact that X is squared in the equation does not mean that it is not a function of X. In this case, Y is a function of X because for each value of X, there is a unique value of Y determined by the equation Y = 16x^2.
This equation represent the distance an object falls (Y) in a certain amount of time (X) assuming that the only force acting on the object is gravity, and the acceleration due to gravity is constant (approximately 9.8 m/s^2 or 32 ft/s^2). The equation Y = 16x^2 is known as the equation of motion under gravity.

sin(25º)/BC = sin(36º)/28
BC = 28 x sin(25º)/sin(36º)
BC = 20.13.
The length AC is obtained as follows:
sin(119º)/AC = sin(36º)/28
AC = 28 x sin(119º)/sin(36º)
AC = 41.62.
