Answer:

see below

Step-by-step explanation:

The area of a circle is given by

A = pi r^2 where r is the radius

A = pi (6.5)^2

A =42.25 pi

If we approximate pi by 3.14

A = 42.25 * 3.14 =132.665

If we use the pi button

A = 132.7322896

4. Give an example of a like term for each of the following: a. 144 b. -95 c. 200 d. h²​
Luda [366]

Answer: 1, -2, 3, 2h^{2}

Step-by-step explanation:

what is... a LIKE TERM????

a like term is a term that you can easily combine in an algebra equation. you can combine them because they share the same terms. FOR EXAMPLE.... YOU CAN COMBINE THESE ON THE LEFT SIDE OF THE EQUAL SIGN:

2x+3x=0

to

5x=0

so for a, b, and c... its basically any number that doesnt have a variable attached to it. THEY COULD BE ANYTHING. like 1, -2, and 3. but for d... its a different story.... because there is h^{2} so a like term could be 2h^{2}

notice that i wrote -2 for b... well theoretically it doesnt even have to be negative because you can combine a negative integer with a positive integer! i just made it negative for convenience....

1. The company has agreed on a 9- character password format, comprised of uppercase letters, lower case letters, and digits (0-9
pochemuha

Answer: a) 1977060966, b) 146581344.

Step-by-step explanation:

Since we have given that

There are 10 numbers,

There are 26 lower case letters,

There are 26 upper case letters,

Since the first 3 characters have to be digits and next 6 can be upper or lower.

So, a) repetitions are allowed:

10^3\times (26+26)^6\\\\=10^3\times 52^6\\\\=1977060966

b) repetitions are not allowed:

^{10}P_3\times ^{52}C_6\\\\=720\times 20358520\\\\=146581344

Hence, a) 1977060966, b) 146581344.
