i dont understand you have everything there
1.) Convert all measurements to meters:
2.5km * 1,000 = 2,500m ; .250km * 1,000 = 250m ; 2,500cm / 100 = 25m
25,000cm / 100 = 250m ; 250mm / 1,000 = .25m
2.) Compare the converted measurements. Therefore, the quantities that are equivalent to 250m are:
.250km ; 25,000cm
The correct question is:
A circle has a radius of 45 units and is centered at (-2.4, -4.8).
What is the equation of this circle?
Answer:
Equation of the circle is;
(x + 2.4)² + (y + 4.8)² = 2304
Step-by-step explanation:
The standard equation of a circle is;
(x - a)² + (y - b)² = r²
where;
(a,b) is the center of the circle and r is the radius of the circle
Now, from the question, the circle is centered at (-2.4, -4.8) and the radius is 45
Thus, plugging those values into the standard form of equation of a circle, we have;
(x - (-2.4))² + (y - (-4.8))² = 48²
This gives;
(x + 2.4)² + (y + 4.8)² = 2304
Answer:
37 in (to the nearest inch)
Step-by-step explanation:
Assume the TV is rectangular ⇒ each corner is a right angle.
We need to find the length of the diagonal, so we can use Pythagoras' Theorem a² + b² = c² where a and b are the legs and c is the hypotenuse (diagonal) side of a right angled triangle.
In this diagram, a and b are the height and width, and the diagonal (c) is the hypotenuse.
Therefore, if a = 18 and b = 32 then:
18² + 32² = c²
324 + 1024 = c²
c² = 1348
c = √(1348)
c = 36.7151195...
c = 37 (rounding up to the nearest integer)
Therefore, the diagonal distance is 37 in (to the nearest inch)
