I'll do problem 12 to get you started

----------------------------------------

Part (a)

The ratio 3:6:7 means the three sides are 3x, 6x and 7x centimeters long. The x is some positive real number.

The longest side is 7x, which is also 16.1, so 7x = 16.1

Divide both sides by 7 to isolate x

7x = 16.1

7x/7 = 16.1/7

x = 2.3

Now we can calculate the other two sides

3x = 3*2.3 = 6.9

6x = 6*2.3 = 13.8

<h3>The other two sides are 6.9 cm and 13.8 cm</h3>

----------------------------------------

Part (b)

Add up the three sides to get

6.9 + 13.8 + 16.1 = 36.8

<h3>The perimeter is 36.8 cm.</h3>

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
