Suppose that 22 inches of wire costs 66 cents.
GaryK [48]

Answer:

51 cents for 17 inches of wire

Step-by-step explanation:

22 = 66

17 = x

22x = 66 * 17

22x = 1122

x = 51 cents

or

22 inches costs 66 cents

1 inch costs 3  cents (66 / 22 = 3  cents)

17 inches costs 51  cents (17 * 3 = 51 cents)

8. Find the area of the following triangle.<br> h=8m<br> b= 6.5
torisob [31]

Answer:

26m^2

Step-by-step explanation:

Area of triangle=1/2b*h

We have,

b=6.5

h=8m

Now,

Area=1/2b*h=1/2*6.5*8=26m^2

Write each expression in simplest form. (√y-√3)(√y+2√3)
Vladimir79 [104]

 We write the expression in its simplest form and we are left with.

y²√3 + y - 6

  Before proceeding let's define an algebraic expression.

<h3>Algebraic expression</h3>

    An algebraic expression is a set of numbers and letters that make up an expression that has a meaning, the letters are variables and the numbers are coefficients or independent terms, algebraic expressions can be part of an equation and model mathematical processes.

     The first thing we will do is to write the expression:

(√y-√3)(√y+2√3)

  Then we perform the multiplication, with the distributive property, which gives as a result

(y + 2√3y - √3y - 6)

y²√3 + y - 6

The given set together with the given operations is not a vector space. list the properties of the definition that fail to hold.
Triss [41]
Let us look at all the axioms of a vector space and see which axioms are broken. 
1) Associativity<span> of addition
</span>[(1,1)\bigoplus(2,2)]\bigoplus(3,3)=(6,6)
[(1,1)\bigoplus[(2,2)]\bigoplus(3,3)]=(6,6)<span>
It's trivial to see this one holds.
2)</span>Commutativity<span> of addition
</span>(1,1)\bigoplus(2,2)=(2,2)\bigoplus(1,1)=(3,3)
<span>This one holds.
3)</span>Identity element<span> of addition
</span><span>This means that we have zero vektor. It is pretty obvious we do, it is (0,0). 
</span>(a,b)\bigoplus(0,0)=(a,b)
4)Inverse elements<span> of addition
</span>This means that for each element in V there exists element -v such that v+(-v)=0. 
We do have inverse elements.
(a,b)\bigoplus(-a,-b)=(a-a,b-b)=0 
5)Compatibility<span> of scalar multiplication with field multiplication
</span>This one holds.
a[b(c,d)]=ab(c,d)
6)<span>Identity element of scalar multiplication
</span>Identity element of scalar multiplication is simply 1.
1\cdot (a,b)=(a,1\cdot b)=(a,b)
7)Distributivity of scalar multiplication with respect to vector addition. Let's look at the definition.
a[(b,c)\bigoplus(d,e)]=a(b,c)\bigoplus a(d,e)
Now let's look at the example:
a[(1,1)\bigoplus(2,2)]=a(3,3)=(3,3a)
a(1,1)\bigoplus a(2,2)=(1,1a)\bigoplus(2,2a)=(3,3a)
This one hold too.
8)<span>Distributivity of scalar multiplication with respect to field addition
</span>Definition of this one is: 
(a+b)(c,d)=a(c,d)+b(c,d)
Let's take a look at the example:
(3+2)(1,2)=5(1,2)=(1,10)
(3+2)(1,2)=3(1,2)+2(1,2)=(1,6)+(1,4)=(2,10)
So this one doesn't hold.
The final answer would be distributivity of scalar multiplication with respect to field addition.
Please note vectors, in this case, are (a,b) and that I did not use the dot to indicate scalar multiplication.
