What is the area of the composite figure?
lana [24]

Hello! :)

\large\boxed{A = 32.5cm^{2}}

We can use the following area to solve for the area of the trapezoid pictured:

A = \frac{1}{2}(b_{1} + b_{2})h

Where:

h = height

b1 = bottom base

b2 = top base

Plug in the given values:

A = \frac{1}{2}(9 + 4)(5)

Simplify:

A = \frac{1}{2}(65)\\\\A = 32.5 cm^{2}

If the diameter of a circle with a circumference of 19.5 inches is reduced by three, what would be the circumference of the new
Elanso [62]

It is given that the circumference of the circle is 19.5 inches. Let the diameter is d inches .

And the formula of circumference is

C= \pi d

Substituting the value of C, we will get

19.5= \pi d
\\
d = \frac{19.5}{ \pi}

When the diameter increased by 3, then the circumference is

C = \pi ( \frac{19.5}{ \pi} +3})=Approx 29 inches

And the circumference , when diameter is increased by 3 is 29 inches .

The Gaineys and the Arnolds are saving money for a trip to Utah to go snowboarding. The Arnolds are going to save a nickel on th
Debora [2.8K]

Write a recursive and explicit formula for each option.

  • The Arnolds

Save a nickel on the first day of the month and then double the amount each day for a month

=> a1 =0.05

=> a2 = a1* 2 = 0.05*2

=> a3 = a2*2 = a1* 2*2

..............................................

=>recursive an = a_{n-1} *2

=> explicit an = 0.05*2^{n-1}

  • The Gaineys

Start their savings by saving  $10  on the first day and then  $10  each day of the month

=> a1 = 10

=> a2 = a1 + 10 = 20

=> a3 = a2 +10 = 20 +10 =30

........................................................

=> recursive an = a_{n-1} +10

=> explicit an = 10 + 10( n-1)

Hope it will find you well.
