Find an equation of the tangent line to the hyperbola y = 3/x at the point (3, 1).
Vesna [10]
Let's find the derivative of that hyperbola in order to find a slope formula to help us with this equation.  We already have an x and y value.  The derivative is found this way:  y'= \frac{x(0)-3(1)}{x^2} so  y'=- \frac{3}{x^2}.  The derivative supplies us with the slope formula we need to write the equation.  Sub in the x value of 3 to find what the slope is: y'=- \frac{3}{3^2}=- \frac{3}{9}=- \frac{1}{3}.  So in our slope-intercept equation, x = 3, y = 1, and m = -1/3.  Use these values to solve for b.  1=- \frac{1}{3}(3)+b  so b = 2.  The equation, then, for the line tangent to that hyperbola at that given point is y=- \frac{1}{3}x+2

The numbers of students in the four
Ludmilka [50]

The total number of students in the four classes is 100 students.

<h3>How to compute the value?</h3>

From the information, the numbers of students in the four sixth-grade classes at Northside School are 26, 19, 34, and 21.

Therefore, the total number of students will be:

= 26 + 19 + 34 + 21

= 100

Therefore there are 100 students.

Please help me. I need how to do the problem too
MatroZZZ [7]

Answer: Choice A.  (8, 4)

==========================================================

Explanation:

Because x = 2y, we can replace every copy of x with 2y

Let's do so in the second equation

3x - 4y = 8

3(x) - 4y = 8

3(2y) - 4y = 8 .... x replaced with 2y; now let's isolate y

6y - 4y = 8

2y = 8

y = 8/2 ..... divide both sides by 2

y = 4

Use this y value to find x

x = 2y

x = 2*4

x = 8

So we have x = 8 and y = 4 pair together to get the answer (x,y) = (8, 4) which is choice A.

Consider the fibonacci sequence below, which is the first term in the sequence to exceed 120?
gizmo_the_mogwai [7]

Answer:

144

Step-by-step explanation:

The sequence is:

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, 1597, 2584, 4181, 6765, 10946

so you can see the first term larger than 120 is the 144.
