The two short sides of a triangle are 3 and 4 inches. what is the length of the hypotenuse,in inches?​
disa [49]

Answer:

The length of the hypotenuse is 5 inches.

Step-by-step explanation:

The formula for finding the hypotenuse is a^{2} + b^{2} = c^{2},

with a and be being the two shorter sides of the triangle, while c is the hypotenuse.

Let's plug in our values for a and b and solve.

4^{2} + 3^{2} = c^{2}

16 + 9 = c^{2}

25 = c^{2}

What is the square root of 25? 5.

The length of the hypotenuse is 5 inches.

The radius of a circle is 14 meters. What is the circle circumference
seropon [69]

Step-by-step explanation:

HERE,

redius of a circle (r)=14 meters.

we know that,

\boxed{\red{\sf{circle~ circumference=2\times \pi \times r   }}} 

<u>According</u><u> </u><u>to</u><u> </u><u>the question</u><u>, </u>

circle circumference=

  • \tt{2\times \pi \times 14   }

      

  • \tt{2 \times \dfrac{22}{7} \times 14   }  

    

  • \tt{2 \times \dfrac{22}{\cancel{7}} \times \cancel{14}}    

  

  • \tt{2\times 22 \times 2   }   

   

  • \tt{ 88~meters   }      

so, the circumference of that circle is <em><u>8</u></em><em><u>8</u></em><em><u> </u></em><em><u>meters</u></em><em><u>.</u></em>

Which is the equation of a line parallel to the line with the equation y= 1/4x +2
natta225 [31]

Answer:

Any line with slope 1/4 like y=1/4x -5.

Step-by-step explanation:

Parallel lines never cross and therefore have the same exact slope. Since slope intercept form is y=mx+b and m is slope, then y=1/4x+2 has a slope of 1/4. Any line with a slope of 1/4 will be parallel. Example: y=1/4x - 5
