Answer:

AE / AD = AB / AC

51 / 51 + 17 = x / x + 12

51 / 68 = x / x + 12

51 ( x + 12) = 68x (After cross multiplication)

51x + 612 = 68x

612 = 68x - 51x

612 = 17x

x = 612/17 = 36

Lcm stands for Least common multiple

The lcm of these numbers is 48

6 - 6, 12, 18, 24, 30, 36, 42, [ 48]

16 - 16, 32, [48 ]

Therefore 48 is the lcm because it is the lowest number 6 and 16 have in common

Find dy/dx for y=log (tan2x)

nekit [7.7K]

Answer:

$\frac{dy}{dx} = \frac{2}{sin2x cos2x}$

Step-by-step explanation:

y = log (tan 2x)

Applying chain rule:

$\frac{dy}{dx} = \frac{d}{dx} (1st function) . \frac{d}{dx} (2nd function). \frac{d}{dx}(3rd function)$

$\frac{dy}{dx} = \frac{d}{dx} log(tan 2x) . \frac{d}{dx} tan2x. \frac{d}{dx} 2x$

$\frac{dy}{dx} = \frac{1}{tan2x} \times sec^{2}2x \times 2$

$\frac{dy}{dx} = \frac{2sec^{2}2x }{tan2x}$

Now since $sec^{2}x = \frac{1}{cos^{2}x } \ and\ tanx = \frac{sinx}{cosx}$

∴ $\frac{dy}{dx} = \frac{2cos2x }{sin2x cos^22x}$

∴ $\frac{dy}{dx} = \frac{2}{sin2x cos2x}$

Eric has started running for exercise. He recorded the number of miles he ran each day this week in the table below.

laila [671]

Answer: 9/14

Step-by-step explanation:

As Eric ran 5/7 of the distance ran on Friday, you have to times 5/7 by the distance ran on Friday.

So we have:

5/7 x 9/10 = 9/14

This is calculated by multiplying the numerators (numbers on top) and the denominators (numbers on the bottom)

Numerators:

5x9 = 45

Denominators:

7x10 = 70

So we now have the new fraction: 45/70, if we simplify this, we get:

45/70 = 9/14

(dividing the top and bottom both by 5)

Hope that makes sense! If you'd like any more help with maths, I'd be happy to offer online tuition. You can find me at: www.birchwoodtutors.com
