Answer:

Perimeter ratio = 2:1

Area ratio = 4:1

Step-by-step explanation:

<u>Perimeter</u>

Perimeter of the smaller photo = 2l+2w

=2(5)+2(4)

=18 inches

Perimeter of larger photo = 2l+2w

=2(10)+2(8)

=36 inches

Ratio:

Perimeter of larger photo : perimeter of smaller photo = 36:18

=2:1

<u>Area</u>

Area of smaller photo = lw

=5\times4

=20 inches²

Area of larger photo = lw

= 10\times8

=80 inches ²

Ratio

Area of larger photo : area of smaller photo = 80:20

=4:1

∴The ratio of the perimeters = 2:1, and the ratio of the areas = 4:1

Hope this helps :)

Find the derivative of y=sin^(2)(x)cos^(2)(x)

sin^{2}x \ cos^{2} x= \frac{1}{2} (1-cos2x) \times \frac{1}{2} (1+cos2x) \\ = \frac{1}{4} (1- cos^{2} 2x) \\ = \frac{1}{4} ( sin^{2} 2x +cos^{2} 2x- cos^{2} 2x) \\ = \frac{1}{4} ( sin^{2} 2x) \\ = \frac{1}{4} ( \frac{1}{2} (1-cos2(2x))) \\ = \frac{1}{8} (1-cos4x) \\  \frac{d}{dx} (sin^{2}x \ cos^{2} x)= \frac{1}{8}  \frac{d}{dx} (1-cos4x) \\ = \frac{1}{8} [-4(-sin4x) \\  \frac{1}{2} sin4x

4 divided by 457. Please list the steps
exis [7]
You find out how many times 4 goes into 4 and get 1 then you find out how many times 4 goes into 5 and get 1 but you subtract 5 minus 4 and get 1 then bring down the 7 to get 17 then find out how many times 4 goes into 17 which is 4 times because 4 times 4 is 16 and you do 17 minus 16 and get 1 then add a decimal and bring down the 1 to get 10 then find out how many times 4 goes into 10 and get 2 subtract and get 2 bring down the zero turn it into 0 then you get 20 then find out how many times 4 goes into 20 and get 5 and 4*5=20 so 20-20 is 0 so your answer is 114.25

kipiarov [429]

Answer:

Ordinary annuity

Step-by-step explanation:

Given : ABC Insurance offers an annuity with 4.5% APR for the next 5 years. You decide to invest $1000 each year into this account.

To find : What type of annuity is this?

Solution :

Annuity is the form of insurance in which some of the money is paid each year to secure for future.

There are two types of annuity:

Ordinary annuity - In this annuity the payment is made at the end of each period  over a fixed length of time. Also in this annuity payments are made monthly, quarterly, semi-annually or annually.

Annuity due - is the opposite of ordinary annuity as in this the payment is made at the beginning of each period.

In the given situation the annuity is ordinary annuity because the investment is done each year for 5 years.
