1) Let's look at what we know and Create an equation:

Perimeter: 6x

Side A: x + 3

Side B: 2x + 4

Side C (Unknown): Let's call this 'a'.

Because you find the perimeter of a figure by adding the lengths of all its sides together, our equation would be (the parentheses are only there to help you visualize):

(X + 3) + (2x +4) + (a) = 6x

(Side A+Side B+Side C = Perimeter)

2) From here, we combine like terms:

3x + 7 + a = 6x

3) Isolate the variable in which we are solving for (a):

<u>a = 3x - 7</u>

Since we cannot simplify any further, the length of the missing side is <u>3x - 7</u>.

PLEASE HELP!!! I don't understand it
Len [333]

Answer:

A

Step-by-step explanation:

This is exponential decay; the height of the ball is decreasing exponentially with each successive drop.  It's not going down at a steady rate.  If it was, this would be linear.  But gravity doesn't work on things that way.  If the ball was thrown up into the air, it would be parabolic; if the ball is dropped, the bounces are exponentially dropping in height.  The form of this equation is

y=a(b)^x, or in our case:

A(n)=a(b)^{n-1}, where

a is the initial height of the ball and

b is the decimal amount the bounce decreases each time.  For us:

a = 1.5 and

b = .74

Filling in,

A(n)=1.5(.74)^{n-1}

If ww want the height of the 6th bounce, n = 6.  Filling that into the equation we already wrote for our model:

A(6)=1.5(.74)^{6-1} which of course simplifies to

A(6)=1.5(.74)^5 which simplifies to

A(6)=1.5(.22190066)

So the height of the ball is that product.

A(6) = .33 cm

A is your answer

Determine whether the set, together with the indicated operations, is a vector space. If it is not, then identify one of the vec
Mama L [17]

Answer:

The answer to the question are

(B) The set is not a vector space because it is not closed under addition. and

(D) The set is not a vector space because an additive inverse does not exist.

Step-by-step explanation:

To be able to identify the possible things that can affect a possible vector space one would have to practice on several exercises.

The vector space axioms that failed are as follows

(B) The set is not a vector space because it is not closed under addition.

(2·x⁸ + 3·x) + (-2·x⁸ +x) = 4·x which is not an eighth degree polynomial

(D) The set is not a vector space because an additive inverse does not exist.

There is no eight degree polynomial  = 0

The axioms for real vector space are

  • Addition: Possibility of forming the sum  x+y which is in X from elements  x and y which are also in X
  • Inverse: Possibility of forming an inverse -x which is in X from an element x which is in X
  • Scalar multiplication: The possibility of forming multiplication between an element x in X and a real number c of which the product cx is also an element of X
