Solve for x over the real numbers:
4 x^2 = 0
Divide both sides by 4:
x^2 = 0
Take the square root of both sides:
Answer:  x = 0

Work out the length of ab, give your answer to 3 significant figures
Aleksandr [31]

Answer:

D = 9.85 units

Step-by-step explanation:

A (1,7) and B(10,3)

Using Distance Formula to find the length

=> Distance Formula = \sqrt{(x2-x1)^2+(y2-y1)^2}

=> D = \sqrt{(10-1)^2+(3-7)^2}

=> D = \sqrt{(9)^2+(-4)^2}

=> D = \sqrt{81+16}

=> D = \sqrt{97}

=> D = 9.85 units (Upto 3 sfs)

Select the correct answer from each drop-down menu. the endpoints of the longest chord on a circle are (4, 5.5) and (4, 10.5). t
torisob [31]

The equation of this circle in standard form is equal to (x - 4)² + (y - 8)² = 5².

Based on the calculations, the equation of this circle in standard form is equal to (x - 4)² + (y - 8)² = 5²

The equation of a circle.

Mathematically, the standard form of the equation of a circle is given by;

(x - h)² + (y - k)² = r²

Where:

h and k represent the coordinates at the center.

r is the radius of a circle.

The midpoint of the given points represents the center of this circle:

h = (4 + 4)/2 = 4

k = (5.5 + 10.5)/2 = 8

Next, we would determine the radius by using the distance formula for coordinates:

r = √[(x₂ - x₁)² + (y₂ - y₁)²]

r = √[(4 - 4)² + (10.5 - 5.5)²]

r = √[0² + 5²]

r = √25

r = 5 units.

Therefore, the equation of this circle in standard form is equal to (x - 4)² + (y - 8)² = 5².

Three-fourths of the tickets had been sold, and there were 420 tickets left. How many tickets were printed?
BabaBlast [244]

Answer: 560 tickets

Step-by-step explanation:

3/4 = 420/x; now cross multiply:

3x = 4(420)

3x = 1,680; now divide both sides by 3, and you get x = 560
