Answer:

8x^6-10x^5+4x^4-5x^3-4x+5

Step-by-step explanation:

Lest distribute the expression given

this is multiply the first term (4x) with the longer expression (2x^5+x^3-1) and then, multiply the second term (-5) with the longer expression (2x^5+x^3-1).

When the above is finish, simply sum all together.

4x* (2x^5+x^3-1)= 8x^6 +4x^4-4x

-5*(2x^5+x^3-1)=-10x^5-5x^3+5

The sum of all together (respecting the coefficient they belong) is shown:

8x^6-10x^5+4x^4-5x^3-4x+5

Part A : formula for circumference = pi*D or 2piR
for circle A.... 8*pi=25.12
therefore pi=3.14
for circle B.... 3*pi=9.42
therefore pi=9.42/3
pi=3.14

part B : formula for Area =
$pi \times {r}^{2}$
for circle A.... 50.24=pi*(8/2)sqr...(because diameter/2= radius)
pi=50.24/16
pi=3.14

for circle B... 7.065=pi*(3/2)sqr...
pi=7.065/2.25
pi=3.14

what do you observe?
the values for pi are all equal... therefore pi is constant.

Please help i dont understand

natita [175]

Answer:

Okay so we need to simplify, which means to find the smallest possible number but for it to be the same.

Step-by-step explanation:

An example is: 12/20 = 3/4

It equals that because 12/20 can be rewritten as 3/4.

Another example is: 24/30 = 4/6

It equals that because 4 can be added into 24 6 times, so it would be written as 4/6.

Another example is: 15/45= 5/15

It equals that because 5 can be fitted into 15 3 times, so the answer is 5/15.

I hope this helps

Is the following relation a function? (6,2) (-2,2) (4,1) (-1,1)

yulyashka [42]

If each x term corresponds to exactly

one y term, the relation is a function.

In the data set shown here, notice that each x term, 6, -2, 4, and -1 appears only once. This means that each x term corresponds to exactly one y term. So yes, the relation is a function.
