Dy/dx e^8x= sin (x+4y)

1 answer:

4 0

Implicit differentiation:
differentiate both sides,
8e^(8x)=cos(x+4y)(1+4y')
Solve for y' to get
y'=[cos(x+4y)-8e^(8x)]/[4cos(x+4y)]

Solve C = 2πr (solve for "r")<br> C = 15

Jobisdone [24]

C = 2 pi r

but c = 15

15 = 2 pi r
15 = 2 * (22/7) * r
r = (15*7) / 2 / 22
r = 2.386

A survey was conducted

inna [77]

Answer: 9/25 or 36%

Step-by-step explanation:

72 + 28 + 62 + 38 = 200

There are 200 people in total and 72 are youngsters who like sport cars.

So, the number of youngsters who like cars out of the total number of people is 72/200.

Now, find a greatest common divisor. In this case, the greatest common divisor is 8.

72 / 8 = 9

200 / 8 = 25

9/25 (fraction)

25 * 4 = 100

9 * 4 = 36

36/100 = 36% (percentage)

natali 33 [55]

Answer:

250 minutes with the flat rate of $29.

$x\leq 250$

x would be the number of minutes called.

$x-250$

Tracy would be charged by $0.35 per minute.

$f(x)=29\\ 0\leq x\leq 250$

$f(x)=0.35(x-250)+29,\\250\leq x\leq ∞$
