The question is about finding the first and second derivatives of y with respect to x. The first derivative dy/dx is found to be (1+t)e^-2t, and the second derivative d2y/dx2 is found to be -2e^-2t.
Explanation:The derivatives are found by differentiating each function with respect to t first, using the product and chain rules, respectively: the derivatives dy/dt and dx/dt are dy/dt = e^-t - te^-t and dx/dt = e^t. Then, dy/dx can be found as (dy/dt)/(dx/dt), and the second derivative d2y/dx2 can be obtained by differentiating dy/dx with respect to x, which will utilize the quotient rule. Specifically, dy/dx = (e^-t(1+t))/(e^t) which simplifies to (1+t)e^-2t, and after a relatively complex differentiation for d2y/dx2, we get -2e^-2t.

What is the maximum number of intersection points a hyperbola and a circle could have?
A. 4
B. 3
C. 1
D. 2 ...?
Answer: A. 4
Step-by-step explanation:
The characteristic equation of a circle is
[tex]x^2+y^2=r^2[/tex]
The characteristic equation of a hyperbola is
[tex]\frac{x^2}{a^2}-\frac{y^2}{b^2}=1[/tex]
The intersection points will be obtained as the solution of the both characteristic equations.
[tex]x^2+y^2=r^2[/tex].......(1)
[tex]\frac{x^2}{a^2}-\frac{y^2}{b^2}=1[/tex].............(2)
⇒[tex]y^2=r^2-x^2[/tex].....(from 1)
put this in (2)
[tex]\frac{x^2}{a^2}-\frac{r^2-x^2}{b^2}=1[/tex]
⇒[tex]y^2=r^2-x^2\\\frac{x^2}{a^2}+\frac{-x^2}{b^2}=1+\frac{r^2}{b^2}[/tex]
⇒[tex]y^2=r^2-x^2\\x^2(\frac{1}{a^2}+\frac{1}{b^2})=1+\frac{r^2}{b^2}[/tex]
⇒[tex]y^2=r^2-x^2\\x^2(\frac{a^2+b^2}{a^2b^2})=\frac{b^2+r^2}{b^2}[/tex]
[tex]\Rightarrow\ x^2=\frac{a^2(b^2+r^2)}{a^2+b^2}\\y^2=\frac{b^2(r^2-a^2)}{a^2+b^2}[/tex]
So there are 2 different values of x and two different values of y, thus the maximum number of intersection points is 4.

which of the following r one dimensional figures?
check all that apply.
a. ray
b. angle
c. square
d. point
e. segment
f. line
Answer: Segment, line, ray
Step-by-step explanation: too answer was confusing and point was wrong.
The answers are a. ray, e. segment and f. line
In geometry, a one-dimensional figure has only length and no other dimensions such as width or height. Let's analyze each option:
Ray - A ray is one-dimensional as it starts from a point and extends infinitely in one direction.Angle - An angle is formed by two rays meeting at a point, which makes it not one-dimensional.Square - A square is a two-dimensional figure with length and width.Point - A point has no dimensions; it is zero-dimensional.Segment - A segment is one-dimensional as it consists of two endpoints and the line connecting them.Line - A line is one-dimensional as it extends infinitely in both directions.Thus, the one-dimensional figures are the ray, segment, and line.
The solution set for -p^2 − 11p = 0 is
Answer:
the solution set is {0,-11}
Step-by-step explanation:
The equation is [tex]-p^2-11p=0[/tex]
The GCF of the left hand side of the expression is -p. Hence, factored out the GCF
[tex]-p(p+11)=0[/tex]
Now, apply the zero product property, we get
[tex]-p=0,p+11=0[/tex]
Now, solve the equations for p
[tex]p=0,p=-11[/tex]
Thus, the solution set is {0,-11}

use the remainder theorem to divide 3x2+10x-8 by x-2 what is the remainder
Answer:
Remainder is 24.
Step-by-step explanation:
Given dividend = 3x² + 10x - 8
and divisor = x - 2
To find: Remainder using Remainder theorem.
Remainder Theorem states that let p(x) be any polynomial of degree greater than or equal to one and let a be any real number. If p(x) is divided by the linear polynomial x - a, then the remainder is p(a).
Let p(x) = 3x² + 10x - 8
using remainder theorem,
Remainder = p(2) = 3 × 2² + 10 × 2 - 8
= 3 × 4 + 20 - 8
= 12 + 12
= 24
Therefore, Remainder is 24.

Mark and John were sharing the $10 cost to rent some video games with another friend. Mark paid $3, John paid of the total, and their friend paid the rest. Who paid the most towards the rental?
John paid the most towards the rental.
Explanation:To determine who paid the most towards the rental, we need to find out how much each person paid. Mark paid $3 and John paid <percentage> of the total. Their friend paid the remaining amount. Since the total cost to rent the video games was $10, we can calculate how much John paid by subtracting what Mark paid from $10 and finding the percentage of that remaining amount.
Subtracting $3 from $10 gives us $7. Since John paid the majority, we can say that he paid 70% of the total. Therefore, John paid the most towards the rental.

Which of the following equations could be used to solve for the tenth term of the following sequence?
15, 13, 11, 9, ...
A(10) = 15 + 10(-2)
A(10) = 15 + 9(-2)
A(10) = 15 + 9(2)
A(10) = 15 + 10(2)
Answer:
Option(B) is correct.
The tenth term is given by [tex]a_{10}=15+9(-2)[/tex]
Step-by-step explanation:
Given : The sequence 15, 13, 11, 9,....
We have to determine the equation that can be used to find the tenth term of the given sequence 15, 13, 11, 9,....
Consider the given sequence 15, 13, 11, 9,..
[tex]a_1= 15, a_2=13, a_3= 11[/tex]
Difference between each term is
[tex]a_2-a_1=13-15=-2\\ a_3-a_2=11-13=-2[/tex]
Since, The difference between each term is constant -2
Thus, The given sequence is an arithmetic sequence with first term 15 and common difference -2.
Thus, The general term is given by
[tex]a_n=a+(n-1)d[/tex]
where a is first term and d is common difference nd n is number of term.
Subsitute, we have,
[tex]a_{10}=15+(10-1)(-2)[/tex]
Simplify, we have,
[tex]a_{10}=15+9(-2)[/tex]
Thus, The tenth term is given by [tex]a_{10}=15+9(-2)[/tex]
