Because it's the numbers that brings it together so it makes it makes it an even number but sometimes numbers put together also makes it even though but that's a different thing that you're talking about but I don't know I guess.

Because every even number is a multiple of 2.  So it can always be
split up into two parts that are EQUAL.  And there you have it ... the
original number is the sum of two EQUAL numbers.

The equation is:
y = 10 sin(π/15 t) + 30 
where 30 represents the initial height of the blade above the ground and π/15 represents the period as we are given that the blade completes two rotation every minute.Finally the 10 represents the length of the blades.

Hope this helps :)

Find the sum of these polynomials
Nuetrik [128]
Hi there! The answer is B.

( {x}^{2}  - x + 7) + (9 {x}^{2}  + 6)
First we work out the parenthesis, which is easy because we can just remove them.

{x}^{2}  - x + 7 + 9 {x}^{2}  + 6
Now rearrange our expression (in order to collect terms later).

{x}^{2}  + 9 {x}^{2}  - x + 7 + 6
Next up is collecting the terms.

10 {x}^{2}  - x  + 13
The answer is B.

~ Hope this helps you!

The pounds of grapes left with seinna is 3.125 or  pounds

Solution:

Given that Sienna has  pounds of grapes

She eats  pound and gives  pounds to her brother

To find: pounds of grapes left with seinna

We can find the pounds of grapes left with seinna by subtracting the pounds of grapes she ate and pounds of grapes she gave to brother from the total pounds of grapes she had

Pounds of grapes left with seinna = total pounds of grapes - pounds of grapes she ate - pounds of grapes she gave to brother

Substituting the values we get,

Thus the pounds of grapes left with seinna is 3.125 or  poundsStep-by-step explanation:

2 Find an equation in the form y = ax? + bx + c for the parabola passing through the points. (3. – 56). (-1, - 16). (-2,- 51)
ehidna [41]

Answer:

Step-by-step explanation:

Many ways to do this in the details.

All start by writing three equations with three unknowns

<em>-56 = a(3²) + b(3) + c</em>

-56 = 9a + 3b + c          1)

<em>-16 = a(-1²) + b(-1) + c</em>

-16 = a - b + c               2)

<em>-51  = a(-2²) + b(-2) + c </em>  

-51  = 4a - 2b + c           3)

subtract equation 2 from equation 1

-40 = 8a + 4b

--10 = 2a + b

b = -10 - 2a                 4)

subtract equation 3 from equation 1

-5 = 5a + 5b

-1 = a + b                   5)

substitute 4 into 5

-1 = a + (-10 - 2a)

-1 = - a - 10

a = - 9

substitute a into 4

b = -10 - 2(-9)

b = 8

substitute a and b into any of 1, 2, or 3

-51  = 4(-9) - 2(8) + c

-51  = -36 - 16 + c

c = 1

y = -9x² + 8x + 1

We can use a plotting calculator to confirm our result.
