So for perimeter you need to find out the total of all the sides. To find out side AB, you make a triangle and find out the hypotenuse.

a=5 and b=6
a square= 25 b square= 36
25+36= 61
Square root of 61 is 7.81

So side AB is 7.81 ft

Now we need to find out side BC.

a=3 and b=4
a square is 9 and b square is 16.
9+16 is 25
Square root of 25 is 5

Side BC is 5 ft.

Because it's a rectangle, side CD will be 7.81 and side DA will be 5.

7.81*2+5*2= 25.62 ft

So the perimeter of the rectangle is 25.62 ft or C.

Find a1, for the given geometric series. Round to the nearest hundredth if necessary. Sn= 86,830, r= 2.2, n=4

larisa86 [58]

Answer:

4,646.30

Step-by-step explanation:

The sum of n terms of geometric sequence can be calculated using formula

$S_n=\dfrac{a_1(1-r^n)}{1-r}$

In your case,

$S_n=86,830\\ \\r=2.2\\ \\n=4\\ \\a_1=?$

Substitute into the formula:

$S_4=\dfrac{a_1(1-2.2^4)}{1-2.2}\\ \\86,830=\dfrac{a_1(1-23.4256)}{-1.2}\\ \\-104,196=a_1(-22.4256)\\ \\22.4256a_1=104,196\\ \\a_1=\dfrac{104,196}{22.4256}\approx 4,646.30$

PLEASE HELP MEEEEEEE!!!!!

Answer:

C 7ft/yr

Step-by-step explanation:

The given points are not all on the same line, so the average will vary depending on the interval of interest.

Over the interval [1, 11] years, the average rate of change of height is ...

change in height / change in years = (80 -10)/(11 -1) = 70/10 = 7 . . . ft/yr

On the interval [11, 15] years, the average rate of change is ...

(105 -80)/(15 -11) = 25/4 = 6.25 . . . ft/yr

Even on this interval, the closest answer choice is C.

The 3 by 3 grid below shows nine 1 cm × 1 cm squares and uses 24 cm of wire. What length of wire is required for a similar 20 by

Nady [450]

Answer:

840

Step-by-step explanation:

Hi there!

Usually, this kind of problem asks us the perimeter rather than the area. But when talking on this grid on how many cms are necessary to construct one made up of 9 squares 1cm x1 cm. We need to check one thing: Some line segments will be used twice. So this is not a classical perimeter question.

1) So we either manually and carefully count it avoiding not doing it twice the same common line segments.

Or.

2) By just applying an algorithm, Where n is the <em>nxn</em> grid

$n(n+1)+n(n+1)=Length \:of \:the \:wire$

So, for the 20x20 grid

$20(20+1)+20(20+1)=length\\\\20(21)+20(21)=length\\length=840 cm$
