Kamila [148]
To factor completely 18b - 32, we factor out the common factor of the two terms and divide each of term by the common factor.

18b - 32 = 2(18b/2 - 32/2) = 2(9b - 16)

Cindy found a collection of baseball cards in her attic worth $8,000. the collection is estimated to increase in value by 1.5% p
Sergio [31]
A]
Exponential function is given by the form:
y=a(b)ˣ
where:
a=initial value
b=growth factor
From the question:
a=$8000, b=1.015, 
thus the exponential growth function of this situation is:
y=8000(1.015)ˣ

b] The value of the collection after 7 years will be:
x=7 years
Using the formula:
y=8000(1.015)ˣ
plugging the values we get:
y=8000(1.015)⁷
y=8,878.76

Answer: $8,878.76

Express the vector r~ a b c d p r in terms of a~ , b~ , c~ , and d~ , the edges of a parallelogram.
Gre4nikov [31]

Given the vector \vec{r}(a,b,c,d).

Now taking the vertices of parallelogram asA \vec{a},B\vec{b},C\vec{c},D\vec{d}.

As we know to find the edges of parallelogram ABCD,we proceed as follows

\vec{AB}= Position vector of B - Position vector of A

                             \vec{b}-\vec{a}

\vec{BC}= Position vector of C - Position vector of B

                            =\vec{c}-\vec{b}

\vec{CD}= Position vector of D - Position vector of C

                           = \vec{d}-\vec{c}

\vec{DA}= Position vector of A - Position vector of D

                       =\vec{a}-\vec{d}

So, \vec{b}-\vec{a},\vec{c}-\vec{b},\vec{d}-\vec{c},\vec{a}-\vec{d} are edges of parallelogram.
