PLZ HELP OOOOHHH Solve for X -1/5(x-4)= -2 x=[_]

zavuch27 [327]

Answer:

X = 10 + 4 Simplified: X = 14

Step-by-step explanation:

-1/5 (x - 4) = -2

distributive property

(-1/5 · x) + (-1/5 · -4) = -2

simplify

-1/5x + 0.8 = -2

multiply each side by -5

X + -4 = 10

simplify

X - 4 = 10

Is 43 a two digit odd number?

Snowcat [4.5K]

Yes. The '4' and the '3' are its two digits, and the '3' in the last place
identifies it as an odd number (not evenly divisible by 2).

What is the simplest form for 10/42

QveST [7]

2 goes into both numbers, so divide both by 2;

10 ÷ 2 = 5

42 ÷ 2 = 21

so 10/42 in simplest form is: 5/21

To find the extreme values of a function f(x,y) on a curve xequalsx(t), yequalsy(t), treat f as a function of the single vari

pychu [463]

Answer:

Absolute maximum is 2

Absolute minimum at -2

Step-by-step explanation:

The given parametric functions are:

$x=2\cos t,y=2\sin t$

By the chain rule:

$f'(t)=\frac{\frac{dy}{dt} }{\frac{dx}{dt} }$

$\frac{df}{dt} =\frac{2 \cos t}{-2\sin t} =-\cot(t)$

At fixed points, $f'(t)=0$

$\implies -\cot (t)=0$

This gives $t=\frac{\pi}{2} ,\frac{3\pi}{2}$ on $0\le t\le 2\pi$

This implies that the extreme points are $(2\cos \frac{\pi}{2}, 2\sin \frac{\pi}{2})=(0,2)$ and $(2\cos \frac{3\pi}{2}, 2\sin \frac{3\pi}{2})=(0,-2)$

By eliminating the parameter, we have $x^2+y^2=4$

This is a circle with radius 2, centered at the origin.

Hence (0,2) is an absolute maximum ,at $t=\frac{\pi}{2}$ and (0,-2) is an absolute minimum at $t=\frac{3\pi}{2}$
