Solve the quadratic equation by completing the square. x^2+14x+47=0. What is the form and solution?

Phoenix [80]

To complete a square for ax²+bx+c, you first make a=1.
in this case, a is already 1
move c to the right side: x²+14x=-47
next, add (1/2 of b)² to both sides, in this case, b=14, half of 14 is 7, so x²+14x+ 7²=-47+7²
the left side is now a perfect square: (x+7)²=2
x+7=√2 or x+7=-√2
x=√2-7, or x=-2-√7

The measures of the angles between the resultant and two applied forces are 26° and

erma4kov [3.2K]

Answer:

48.8 lbs

Step-by-step explanation:

The forces can be modeled by a triangle with acute angles 20° and 26°, and obtuse angle 134° opposite a side of length 80. The larger component force will be opposite the angle 26°, and can be found using the Law of Sines:

a/sin(A) = c/sin(C)

x/sin(26°) = 80/sin(134°)

x = 80sin(26°)/sin(134°) ≈ 48.753 . . . . pounds

The larger component force is about 48.8 pounds.

The true statement based on the histogram is

There were no lap times between 35 and 36 seconds.

The correct option is (A).

<h3>What is Histogram?</h3>

A histogram is a graphical representation that organizes a group of data points into user-specified ranges.

Given:

indoor running track is 200 meters in length.

Also, a 3,000-meter race, runners must complete 15 laps of the track.

As, there no data for interval 35-36.

So, there were no lap times between 35 and 36 seconds.

Hence, The interval from 37 to 38 seconds saw the most lap times.

Evaulate 10^2 + 6 multiplied by 7 + 8

Alinara [238K]

Evaluating $10^2 + 6 \,\,multiplied\,\, by\,\, 7 + 8$ we get 1590

Step-by-step explanation:

We need to evaluate $10^2 + 6 \,\,multiplied\,\, by\,\, 7 + 8$

Solving:

$10^2 + 6 \,\,multiplied\,\, by\,\, 7 + 8\\=(10^2+6)\times(7+8)\\=(100+6)\times(15)\\=106\times15\\=1590$

So, evaluating $10^2 + 6 \,\,multiplied\,\, by\,\, 7 + 8$ we get 1590
