Answer:

$11

Step-by-step explanation:

Kim has $20

→ Subtract $12 since "She spends $12 on a fishing pole"

$20 - $12 = $8

→ Add $3 since " she finds $3"

$8 + $3 = $11

Write the equation for the perpendicular bisector of the given line segment.

Anon25 [30]

Answer:

$y=\frac{1}{3}x+\frac{5}{3}$

Step-by-step explanation:

Let

A(-5,5),B(-2,-4) ----> the given segment

step 1

Find the slope AB

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the given values

$m=\frac{-4-5}{-2+5}$

$m=\frac{-9}{3}$

$m=-3$

step 2

we know that

If two lines are perpendicular, then their slopes are opposite reciprocal (the product of the slopes is equal to -1)

so

the slope of the perpendicular bisector is equal to

$m_1*m_2=-1$

we have

$m_1=-3$

substitute

$(-3)*m_2=-1$

$m_2=\frac{1}{3}$

step 3

Find the midpoint segment AB

A(-5,5),B(-2,-4)

The formula to calculate the midpoint between two points is equal to

$M(\frac{x1+x2}{2} ,\frac{y1+y2}{2})$

substitute the values

$M(\frac{-5-2}{2} ,\frac{5-4}{2})$

$M(-\frac{7}{2} ,\frac{1}{2})$

step 4

Find the equation of the line in point slope form

$y-y1=m(x-x1)$

we have

$m=\frac{1}{3}$

$M(-\frac{7}{2} ,\frac{1}{2})$

substitute

$y-\frac{1}{2}=\frac{1}{3}(x+\frac{7}{2})$

step 5

Convert to slope intercept form

$y=mx+b$

isolate the variable y

$y-\frac{1}{2}=\frac{1}{3}x+\frac{7}{6}$

$y=\frac{1}{3}x+\frac{7}{6}+\frac{1}{2}$

$y=\frac{1}{3}x+\frac{10}{6}$

simplify

$y=\frac{1}{3}x+\frac{5}{3}$

Find the first four terms of the sequence given by the following.<br> an = 32+(n-1)-3, n=1, 2, 3...

natta225 [31]

The first four terms are 32,29,26,23

Step-by-step explanation:

Given sequence is:

$a_n=32+(n-1)(-3)\\$

We will put n=1,2,3,4

Putting n=1 in formula of sequence

$a_1=32+(1-1)(-3)\\=32+(0)(-3)\\=32+0\\=32$

Putting n=2

$a_2=32+(2-1)(-3)\\=32+(1)(-3)\\=32-3\\=29$

Putting n=3

$a_3=32+(3-1)(-3)\\=32+(2)(-3)\\=32-6\\=26$

Putting n=4

$a_4=32+(4-1)(-3)\\=32+(3)(-3)\\=32-9\\=23$

The first four terms are 32,29,26,23
