Answer:

1 ) 180 - 71 = 109

2) 5x +x = 180 ; 6x = 180 ; x = 180/6 = 30

3) 90

4) x + 6x+8 + x+12 = 180 ; 8x + 20 = 180 ; 8x = 160/8= 30

5) 180 -110 = 70

6) m = 180- 119 = 61

7) 90

8) 11y - 36 = 63 ; y = 99/11 = 9

(Q7) 180

(Q8) 2x+x = 3x = 90 ; x = 90/3 = 30

(Q15) 157

(Q16) 5x + 4 + (x-2) + (3x+7) = 180

9x +9 = 180 ; x = 171 / 9 = 19

I hope im right!!

The rectangle shown is enlarged such that each side is multiplied by the value of the width, 2x. Which expression represents the

kykrilka [37]

Answer:

<h2> The answer is </h2><h2> D. 8x^2+4xy</h2>

Step-by-step explanation:

We know that the expression for the perimeter is given as

P=2l+2B

now given that the value of the width is =2x

length= 4x

and the breadth=y

P=4x+2y

let us multiply both the length and the width with 2x we have

P=2x(4x+2y)

P=8x^2+4xy

the answer is

D. 8x^2+4xy

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 $t=\frac{3\pi}{2}$
