Answer:

Step-by-step explanation:

The distance around the lot is the perimeter of the lot, which has a formula:

P 2L + 2W

We can fill in using the info given:

$P=2(\frac{9}{8})+2(\frac{9}{10})$ which multiplies to

$P=\frac{18}{8}+\frac{18}{10}$ and finding a common denominator:

$P=\frac{90}{40}+\frac{72}{40}$ and adding, gives you

$P=\frac{162}{40}=4.05mi$

Y=-6x+5

It can be a function because a function don't have a unknow
it can be both
and netheir

y is equal to a function so they relating
its called relation

Type the correct answer in each box.

Answer:

$(x-5)^2+(y+4)^2=100$

Step-by-step explanation:

step 1

Find the radius of the circle

we know that

The distance between the center and any point that lie on the circle is equal to the radius

we have the points

(5,-4) and (-3,2)

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

substitute the values

$r=\sqrt{(2+4)^{2}+(-3-5)^{2}}$

$r=\sqrt{(6)^{2}+(-8)^{2}}$

$r=\sqrt{100}\ units$

$r=10\ units$

step 2

Find the equation of the circle

we know that

The equation of a circle in standard form is equal to

$(x-h)^2+(y-k)^2=r^2$

where

(h,k) is the center

r is the radius

we have

$(h,k)=(5,-4)\\r=10\ units$

substitute

$(x-5)^2+(y+4)^2=10^2$

$(x-5)^2+(y+4)^2=100$

Find the difference in simplest form. <br> 2b/b^2-2b+1 - 2/b^2-2b+1

kolezko [41]

1) factor the denominators: 2b/(b-1)2 - 2/ (b-1)2
2) MAKE SURE YOU HAVE A COMMON DENOMINATOR
3) combine the numerators: 2b-2/(b-1)2
4) distribute 2 from numerator: 2(b-1)/(b-1)2
5) simplify; answer is 2/(b-1)
