Find the equation of the circle that has a diameter with endpoints (7,3) and (7,-5)

muminat

Answer:

(x-7)² + (y+1)² = 4² or (x-7)² + (y+1)² =16

Step-by-step explanation:

1) coordinates of the center

x0=(x1+x2)/2=(7+7)/2=7

y0=(y1+y1)/2=(3-5)/2 = -1

(7, -1) - coordinates of the center

2) radius of the circle

length of the diameter =√((x2-x1)²+(y2-y1)²)=√((7-7)²+(-5-3)²)=√(8)²= 8

r = length of the radius = length of the diameter / 2 = 8/2 = 4

3) the equation of the circle

(x-x0)² + (y-y0)²= r²

(x-7)² + (y+1)² = 4²=16

Joe's annual income has been increasing in the same dollar amount. The first year his income was $15,200, and the 4th year his i

lidiya [134]

Answer:

Therefore 6th year his income was $19,700.

Step-by-step explanation:

Given, Joe's annual income has been increasing in some dollar amount . The first year his income was $15,200 and 4th year his income was $17,900.

A=$17900, P= $15,200 and n = 3 year

$A= P(1+\frac{r}{100} )^n$

$\Leftrightarrow 17900=15200(1+\frac{r}{100})^3$

$\Leftrightarrow (1+\frac{r}{100})^3=\frac{17900}{15200}$

$\Leftrightarrow (1+\frac{r}{100})=(\frac{17900}{15200})^{\frac{1}{3} }$

$\Leftrightarrow \frac{r}{100}=(\frac{17900}{15200})^{\frac{1}{3} }-1$

$\Leftrightarrow r=5.60$

Let $t^{th}$ year Joe's income was $19,700.

$\therefore 19700=15,200(1+\frac{5.60}{100} )^{t-1}$

$\Leftrightarrow 1.296= (1+0.056)^{t-1}$

$\Leftrightarrow 1.296= (1.056)^{t-1}$

$\Leftrightarrow log(1.296)= (t-1)log(1.056)$

$\Leftrightarrow \frac{log(1.296)}{log(1.056)}= (t-1)$

$\Leftrightarrow t-1= 4.75$

$\Leftrightarrow t= 4.75+1$

$\Leftrightarrow t = 5.75$ ≈6

Therefore 6th year his income was $19,700.

There are 486 hamsters at a private showing of a new documentary about humans. If there are 12 seats in each row, about how many

Citrus2011 [14]

Answer:

40 rows will hamsters fill

Step-by-step explanation:

As per the statement:

There are 486 hamsters at a private showing of a new documentary about humans.

⇒Total number of hamsters = 486

It is also given that there are 12 seats in each row.

then;

They will fill = $\frac{486}{12} = 40.5$

Therefore, the best estimate the rows will hamsters fill is 40 rows.
