Answer:

( x-3) ^2 + ( y-1) ^2 = 4

Step-by-step explanation:

The equation for a circle is given by

( x-h)^2 + ( y-k) ^2 = r^2 where (h,k) is the center and r is the radius

( x-3) ^2 + ( y-1) ^2 = 2^2

( x-3) ^2 + ( y-1) ^2 = 4

Two bumper cars are driven straight toward

Evgen [1.6K]

By conservation of momentum,

(110.0 kg) (1.5 ms⁻¹) + (170.0 kg) (-2.0 ms⁻¹) = (110.0 kg) (-2.75 ms⁻¹) + (170.0 kg) v

where v is the final velocity of the second car.

Solve for v :

-175 kg•ms⁻¹ = -302.5 kg•ms⁻¹ + (170.0 kg) v

127.5 kg•ms⁻¹ = (170.0 kg) v

v = (127.5 kg•ms⁻¹) / (170.0 kg) = 0.75 ms⁻¹

At a local movie theatre, sodas cost $4.50 and bags of popcorn cost $1.50. Kirk buys three times as many bags of popcorn as soda

BigorU [14]

Based on the calculations, Kirk bought 2.4 bags of popcorn and 7.2 sodas.

Let the number of sodas bought be s.

Let the number of bags of popcorn be p.

<u>Given the following data:</u>

Cost of soda = $4.50.

Cost of popcorn = $1.50.

Total price = $36.

a. To write a system of equations that models this scenario:

<h3>What is a system of equations?</h3>

A system of equations can be defined as an algebraic equation of the first order that has two (2) variables with each of its term having an exponent of one (1).

<h3>For the soda and popcorn:</h3>

$4.5s+1.5p=36$ ...equation 1.

Translating the word problem into an algebraic expression, we have;

Three times as many bags of popcorn as sodas:

$3p=s$ ...equation 2.

b. To determine how many of each item Kirk bought:

Substituting eqn. 2 into eqn. 1, we have:

$4.5(3p)+1.5p=36\\\\13.5p+1.5p=36\\\\15p=36\\\\p=\frac{36}{15}$

p = 2.4 bags of popcorn

$s=3p\\
\\
s=3 \times 2.4$

s = 7.2 sodas.
