Find d2y/dx2 in terms of x and y if (x^2)-(y^2)=16.

1 answer:

5 0

We can use implicit differentition to determine the second derivative of y in terms of x. In this case, the first derivative is 2x dx - 2y dy = 0. The second derivative is 2 d2x - 2 d2y = 0. Hence d2y/d2x is equal to 1.

$\frac{4}{5} + \frac{3}{15} - \frac{2}{3} \\$

Taking LCM

$\frac{12 + 3 - 10}{15} \\ \\ \longrightarrow \: \cancel\frac{5}{15} \\ \\ \longrightarrow \: \frac{1}{3}$

Is there a easy way to subtract fractions with unlike deiomaters

Angelina_Jolie [31]

Answer:

Yes

Step-by-step explanation:

It's just like adding fractions where you have to find the common denominator so the fractions can be subtracted.

Example

$\displaystyle \frac{1}{2}-\frac{1}{3}=\frac{1*3}{2*3}-\frac{2*1}{2*3}=\frac{3}{6}-\frac{2}{6}=\frac{1}{6}$

two trains leaves stations 320miles apart at the same time and travel toward eachother. One train travels at 110 miles per hour

I am Lyosha [343]

x/110 = (320-x)/90

Cross multiply

90x = 35200-110x

200x=35200

X = 35200/200 = 176 (distance traveled by train going 110 mph

176/110 = 1.6 hours = 1 hour and 36 minutes

Check: 110*1.6 = 176, 90*1.6 = 144

176+144 = 320

it will take 1.6 hours ( 1 hour 36 minutes) for the trains to meet

If 3 is subtracted from twice a number, the result is 8 less than the number. Write an equation to solve this problem.

lakkis [162]

3 subtracted from twice a number=2x-3
8 less than the number=x-8
2x-3=x-8
x=-5
