The equation of a circle is (x + 12)2 + (y + 16)2 = (r1)2, and the circle passes through the origin. The equation of the circle

Furkat [3]

For an equation to pass through the origin, (0,0) must be a solution of the equation. So, for the first one,

$(x + 12)^{2} + (y + 16)^{2} = r_{1}^{2}$

(0, 0) must satisfy the equation and we can solve for the value of r₁ as shown below.

$(0 + 12)^{2} + (0 + 16)^{2} = r_{1}^{2}$
$12^{2} + 16^{2} = r_{1}^{2}$
$r_{1} = \sqrt{12^{2} + 16^{2}}$
$r_{1} = 20$

Since the second equation of the circle also passes through the origin, we use the same steps from the first one.

$(0 - 30)^{2} + (0 - 16)^{2} = r_{2}^{2}$
$r_{2} = \sqrt{30^{2} + 16^{2}}$
$r_{2} = 34$

Thus, we have the values for r₁ and r₂ as 20 and 34, respectively.

Answer: r₁ = 20 and r₂ = 34

Which linear equation represents on the graph

s2008m [1.1K]

Remember, rise/run is the easiest way to determine slope

y=mx+b is form

mx is slope, whilst b is y int

so, answer? y=-3x-2

Or A.

The town of Madison has a population of 25{,}00025,00025, comma, 000. The population is increasing by a factor of 1.121.121, poi

cestrela7 [59]

Answer:

$P(t)=25,000(1.12)^t$

Step-by-step explanation:

we know that

The equation of a exponential growth function is given by

$P(t)=a(b)^t$

where

P(t) is the population in Madison

t is the number of years

a is the initial value

b is the factor of growth

we have

$a=25,000\ people\\b=1.12$

substitute

$P(t)=25,000(1.12)^t$

A rectangular block measures 3 cm x 4 cm x 3 cm how much water would it displace?

nika2105 [10]

Answer:

36c^3m^3x^2

Step-by-step explanation:

you first multiply 3 cm by 4 cm by 3 cm to get 36 cm.
its mass in air and its effective mass when submerged in water (density = 1 gram per cubic centimeter).
1.0 g/cm3
then you get the answer 36c^3m^3x^2

Lauren is running in a marathon to raise money for her favorite charity. The total distance of the marathon is 12.5 miles. So fa

kirill [66]

Hi! So when you are dividing or multiplying a decimal by 10, it becomes a lot easier than it looks. If you divide by 10, you move the decimal to the left one space. If you multiply the decimal by 10, you move the decimal to the right one space. Because you are diving 12.5 by 10, you move the decimal to the left one space, which then becomes 1.25. So, Lauren has run 1.25 miles. If you want to double check, you can multiply 1.25 by 10, which comes out to 12.5. Your answer is 1.25! Hope this helps!!
