Answer:

Step-by-step explanation:

In simpler words mathematics is the study of numbers , quantities, or shapes.

It is the science of structure, order, and relation that has evolved from elemental practices of counting, measuring, and describing the shapes of objects. It deals with logical reasoning and quantitative calculation, and its development has involved an increasing degree of idealization and abstraction of its subject matter.

Math is all around us, in everything we do. It is the building block for everything in our daily lives, including mobile devices, architecture (ancient and modern), art, money, engineering, and even sports...

The Becks buy a plastic tarp to cover their firewood. A rectangle that is eight and one-third yards long and six and three-fourt

Dmitriy789 [7]

Answer:

56 1/4 yards

Step-by-step explanation:

Area of the tarp = length × width

Length = 8 1/3 yards

Width = 6 3/4 yards

Area of the tarp = length × width

= 8 1/3 yards × 6 3/4 yards

= 25/3 × 27/4

= (25 * 27) / (3 * 4)

= 675 / 12

= 56 1/4 yards

Area of the tarp = 56 1/4 yards

Use the formula for secants in a circle. The formula for us in our situation is $x^2=239,000(239,000+8,000)$ . Work within the parenthesis first to get $x^2=239,000(247,000)$ . Do the multiplication now to get $x^2=5.9033*10^{10}$ . Take the square root of that to get x = 242,967.076 miles or, according to how your answer is to be stated, 243,000 miles.

The length of a chord is equal to its distance to the center of the circle. A second chord in the same circle is twice as long a

Rama09 [41]

Answer:

The distance from the center of the circle to the longer chord is twice smaller than the distance from the center to the shorter chord.

Step-by-step explanation:

The length of the chord AB is the same as the distance OC from the center to the cord. Let OC=2x, then CA=x. By the Pythagorean theorem, the radius r of the circle is

$r^2=OC^2+AC^2,\\ \\r^2=(2x)^2+x^2=5x^2,\\ \\r=\sqrt{5}x.$

The length of the arc ED is 4x.

Consider right triangle EFO. In this triangle, EF=2x, EO=r, then the distance OF is

$OF^2=OE^2-EF^2,\\ \\OF^2=5x^2-(2x)^2=x^2,\\ \\OF=x.$

The distance from the center of the circle to the longer chord is twice smaller than the distance from the center to the shorter chord.

Mashutka [201]

Answer:

√74

Step-by-step explanation:

there is no y.

wx=<8-3,-3+3,-6-1>=<5,0,-7>
