Answer:
Equation of given circle :- x² + y² = 4
Step-by-step explanation:
The equation of the circle with center (0, 0) and radius r is given by,
x² + y² = r²
It is given that, a circle with center (0,0) and (-1,-3) a point on the circle
To find the radius of circle
radius r = √[(0 - - 1)² + (0 - -3)²] =√(1 + 3) =√4 = ±2
r = 2
<u>To find the equation of circle</u>
x² + y² = r²
x² + y² = 2²
x² + y² = 4
Answer: B. 2.5 in
Step-by-step explanation:
From the given right angle triangle,
the hypotenuse of the right angle triangle is the unknown side.
With m∠32 as the reference angle,
the adjacent side of the right angle triangle is 4 in
the opposite side of the right angle triangle is w
To determine w, we would apply
the tangent trigonometric ratio which is expressed as
Tan θ = opposite side/adjacent side. Therefore,
Tan 32 = w/4
w = 4tan32 = 4 × 0.625
w = 2.5 in
6--3=9
15-6=9,
so
24+9=33,
33+9=42,
42+9=51
33,42,51
Answer:
The one with the better deal would be 30 ride tickets for $22.50 this is because you pay less money for more rides.
Step-by-step explanation:
First you divide 20 by 14. Doing this will give you the cost of a ride per ticket.
20/14 = 1.42
Then you do the same thing to 30 and 22.50.
30/22.50 = 1.30
Last you compare which deal has less money per ride.
1.42 > 1.30
