In a right triangle, this formula can be used:
a^2 + b^2 = c^2
when a and b are the legs and c is the hypotenuse.
Substitute the numbers from the problem into the formula.
14^2 + b^2 = 18^2
Simplify.
196 + b^2 = 324
b^2 = 128
b = square root of 128 = 11.3137...
When 11.313 is rounded to the nearest tenth, it is 11.3
The length of the other leg is 11.3 centimeters.
Hope this helps!
Answer:
5/8
Step-by-step explanation:
total is 16
and point is on 10th line
therefore 10/16 is equals to 5/8
Answer:
81 in^2
Step-by-step explanation:
Well the formula to find an area of a triangle is (bh) / 2
In this case the base is 18 and the height is 9
18*9=162
162/2=81
Given:
The vertex of a quadratic function is (4,-7).
To find:
The equation of the quadratic function.
Solution:
The vertex form of a quadratic function is:
...(i)
Where a is a constant and (h,k) is vertex.
The vertex is at point (4,-7).
Putting h=4 and k=-7 in (i), we get
The required equation of the quadratic function is where, a is a constant.
Putting a=1, we get
![[\because (a-b)^2=a^2-2ab+b^2]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%28a-b%29%5E2%3Da%5E2-2ab%2Bb%5E2%5D)
Therefore, the required quadratic function is .
