Crazy boy [7]3 years ago

area = l x w

w = area : l

w = 5.612 x 10¹⁴ : 9.2 x 10⁷

w = 6.1 x 10⁶

the perimeter: 2(l+w)

= 2(9.2 x 10⁷ + 6.1 x 10⁶)

=1.84 x 10⁸ + 1.22 x 10⁷

=10⁷(18.4+1.22)

= 1.962 x 10⁸ cm

Answer:

P = 2.0 × 10⁸ cm

Step-by-step explanation:

5.612 × 10¹⁴ = 9.2 × 10⁷ · x

6.1 × 10⁶ = x
9.2 × 10⁷ + 9.2 × 10⁷ + 6.1 × 10⁶ + 6.1 × 10⁶ = 1.962 × 10⁸ cm

Find all solutions in the interval [0,2pi).<br> 2sin^2(x)=sin(x)
SIZIF [17.4K]

2\sin^2 x  =\sin  x \\\\\implies 2 \sin^2 x -  \sin x=0\\\\\implies \sin x(2 \sin x -1) =0\\\\\implies \sin x =  0~~\text{or}~~ 2 \sin x -1 =0\\\\\implies \sin x = 0~~ \text{or}~ ~ \sin x = \dfrac 12\\\\\text{For}~~ \sin x = 0\\\\x=n\pi \\\\\text{In the interval,}~~[0, 2\pi)\\\\x=0, \pi\\\\\text{For}~~ \sin x = \dfrac 12\\\\x=n\pi+(-1)^n \dfrac{\pi}6 \\\\\text{In the interval,}~~[0, 2\pi)\\\\x=\dfrac{\pi}6,~ \dfrac{5\pi}6\\\\\text{Hence,}~ x = 0,~\pi,~ \dfrac{\pi}6, ~\dfrac{5 \pi}6

10 Y What is the vertical change from Point A to Point B? 9 8 What is the horizontal change from Point A to Point B? 7 6 What is
Alina [70]

Answer:

0.5

Step-by-step explanation:

From the graph given ;

The vertical distance ; y - axis :

(y2 - y1) ; y2 = 2 ; y1 = 1

y2 - y1 = 2 - 1 = 1

The horizontal distance ; the x - axis :

(x2 - x1) ; x2 = 4 ; x1 = 2

x2 - x1 = 4 - 2 = 2

The slope ; the rate of change :

Change in y / change in x

The rate of change ;

(y2 - y1) / (x2 - x1) = 1 / 2

disa [49]

The diameter of the circle is the same as the side length of the bounding square. The radius of the circle is 8 in, so the side length of the square is 16 in.

Then the area between the square and circle is obtained by subtracting the area of the circle from the area of the square:

A_{\rm circle}=\pi(8\,\mathrm{in})^2=64\pi\,\mathrm{in}^2

A_{\rm square}=(16\,\mathrm {in})^2=256\,\mathrm{in}^2

and the area you want is

256-64\pi\,\mathrm{in}^2\approx54.9\,\mathrm{in}^2

sleet_krkn [62]
<span>Wanda started walking along a path 27 seconds before Dave. Wanda walked at a constant rate of 3 feet per second. Dave walked along the same path at a constant rate of 4.5 feet per second. How long after Dave starts walking will he catch up with Wanda ?
***
let x=travel time of Dave
x+27=travel time of Wanda
speed*travel time=distance (same for both Wanda and dave)

..
4.5x=3(x+27)
4.5x=3x+81
1.5x=81
x=54
How long after Dave starts walking will he catch up with Wanda ? 54 sec</span>
