Answer:

60 x 130

Step-by-step explanation:

             w

           ____

           |         |

w+70   |         |   w+70

           |         |

           ---------

                w

add all the sides

2(w+70)+2w=380

2w+140+2w=380

4w+140=380

move the 140 to the other side of the =

4w=380-140

4w=240

divide both sides by 4

w=60

to get the length plug in 60 to w+70   to get 130 and width is just 60.

Find two numbers whose product is -2, and whose sum is -1.​
PIT_PIT [208]

Answer:

x=-2  \ \ \ and \ \ \  y=1

Step-by-step explanation:

Suppose numbers are <em>x</em> and <em>y</em>

<u>Product of </u><em><u>x</u></em><u> and </u><em><u>y</u></em><u> is </u><em><u>-2</u></em>

<u />xy=-2

And sum of <em>x</em> and <em>y</em> is <em>-1</em>

x+y=-1

x=-2  \ \ \ and \ \ \  y=1

What part of the circumference is an arc whose measure is 30°?<br> 1/12<br> 1/10<br> 1/8<br> 1/6
GrogVix [38]

Answer:

1/12

Step-by-step explanation:

The whole circumference (i.e complete circle) is an arc which measures 360°

in our case, it is given that our arc measures only 30°

the fraction of our arc of 30° to the complete circle of 360° is

30/360

= 3/36

= 1/12

Find a power series representation for the function. (Give your power series representation centered at x = 0.) f(x) = x/6x^2 +
timama [110]

Looks like your function is

f(x)=\dfrac x{6x^2+1}

Rewrite it as

f(x)=\dfrac x{1-(-6x^2)}

Recall that for |x|, we have

\dfrac1{1-x}=\displaystyle\sum_{n=0}^\infty x^n

If we replace x with -6x^2, we get

f(x)=\displaystyle x\sum_{n=0}^\infty\frac(-6x^2)^n=\sum_{n=0}^\infty (-6)^n x^{2n+1}

By the ratio test, the series converges if

\displaystyle\lim_{n\to\infty}\left|\frac{(-6)^{n+1} x^{2(n+1)+1}}{(-6)^n x^{2n+1}}\right|=6|x^2|\lim_{n\to\infty}1=6|x|^2

Solving for x gives the interval of convergence,

|x|^2

We can confirm that the interval is open by checking for convergence at the endpoints; we'd find that the resulting series diverge.

If the tip varies directly with the number of guest,which equation represents the relationshipbbetween the tip,t,and the number
sergejj [24]
<span>If the tip, t, varies directly with the number of guests, g, then it means that any change in tip there is a corresponding change in the number of guests. When the tip increases the number of guests increases as well. Therefore,

t </span>α g

To change the it to equal sign, we incorporate a proportionality constant, k.

t =<span> kg
</span>
This equation will represent the relation of t to g.
