Answer:

(5.5, 2)

Step-by-step explanation:

Points given:

(3, -3) and (7,5)

Partition ratio:

5 to 3

Formula for the point:

x = x1 + a/(a+b)×(x2 - x1)
y = y1 + a/(a +b)×(y2 - y1)

So the points are:

x = 3 + 5/(5+3)×(7-3) = 3 + 5/8×4 = 5.5
y = -3 + 5/8×(5 - (-3)) = -3 + 5/8×8= 2

Q4) The admission fee at a small fair is $2 for children and $4.00 for adults.

professor190 [17]

9514 1404 393

Answer:

150 children
200 adults

Step-by-step explanation:

The equations can be written as ...

y = 350 -x . . . . . . . . total number of people

4x +2y = 1100 . . . . . admission fees collected

Substituting for y, we have ...

4x +2(350 -x) = 1100

2x = 400 . . . . . . . . . . . . subtract 700, collect terms

x = 200

y = 350 -200 = 150

150 children and 200 adults attended the fair.

Alex wants to have $2,500 in his bank account after 2 years. If the account earns 5% interest compunded 2 times per year, how mu

natka813 [3]

$A=P(1+ \frac{r}{n})^{nt}$
A=futurer amount
P=present amount
r=rate in decimal
n=number of times compounded per year
t=time in years

A=2500
r=0.05
n=2
t=2

$2500=P(1+ \frac{0.05}{2})^{(2)(2)}$
$2500=P(1+ 0.025)^{4}$
$2500=P(1.025)^{4}$
$2500=P(1.025)^{4}$
divide both sides by [tex} 1.025^{4} [/tex]
2264.88=P

he should invest
$2264.88
