Square root of 648.7209 by division method

Mathematics
1 answer:
SpyIntel [72]3 years ago
6 0

Answer:

25.47

Step-by-step explanation:

This root can be rewritten as:

\sqrt{\frac{6487209}{10000} }

\sqrt{\frac{6487209}{100^{2}} }

\frac{1}{100}\cdot \sqrt{6487209}

Since 6487209 is a multple of 3, the expression can be rearranged as follows:

\frac{1}{100}\cdot \sqrt{3\times 2162403}

2162403 is also a multiple of 3, then:

\frac{1}{100}\cdot \sqrt{3^{2}\times 720801}

\frac{3}{100}\cdot \sqrt{720801}

720801 is a multiple of 3, then:

\frac{3}{100}\cdot \sqrt{3\times 240267}

240267 is a multiple of 3, then:

\frac{3}{100}\times \sqrt{3^{2}\times 80089}

\frac{9}{100}\cdot \sqrt{80089}

80089 is a multiple of 283, then:

\frac{9}{100}\cdot \sqrt{283^{2}}

\frac{9\times 283}{100}

\frac{2547}{100}

Answer:

D. 251.2 feet

Step-by-step explanation:

On carefully observing the diagram,it can be seen that 80 feet is the diameter of the circular ride, i.e.,the circle,in this case.

The radius of the circle will be half the diameter,r=(80/2) feet=40 feet

The distance of one complete loop of this circular path will be the circumference of the circle.

So, Circumference

=2*π*r

=2*3.14*40 feet

=251.2 feet [ANS]

Round your answer to the nearest hundreth​
Juliette [100K]

Answer:

<em>201.06 sq. ft.</em>

Step-by-step explanation:

Area of a circle is found by using the equation:

A = \pi r^{2}

Radius = 1/2 (diameter) = 1/2 (16) = 8

So plug in:

A = \pi (8)^{2}

A = 64\pi

A = 201.06193

Rounded A= 201. 06

What is the equation of the line that passes through the origin and is perpendicular to the line 4x+3y=6
frez [133]

The Equation of a Line

The slope-intercept form of a line can be written as:

y = mx + b

Where m is the slope of the graph of the line and b is the y-intercept.

In the specific case where the line passes through the origin (0,0), we can find the value of b by substituting x=0 and y=0:

0 = m(0) + b

Solving for b:

b = 0.

Thus, the equation of the line reduces to:

y = mx

We only need to find the value of the slope.

That is where we need the second data. Our line is perpendicular to the line of equation 4x + 3y = 6.

Solving for y:

y=-\frac{4}{3}x+2

The slope of the second line is -4/3.

We must recall that if two lines of slopes m1 and m2 are perpendicular, then:

m_1\cdot m_2=-1

Substituting the value of m1 and solving for m2:

\begin{gathered} -\frac{4}{3}\cdot m_2=-1 \\ m_2=\frac{3}{4} \end{gathered}

The slope of our line is 3/4 and the required equation is:

y=\frac{3}{4}x

From this last equation, we need to find the general form of the line.

Multiply both sides of the equation by 4:

4y = 3x

Subtract 3x on both sides:

4y - 3x = 0

Reorder:

-3x + 4y = 0
