Answer:
Step-by-step explanation:
<h3>Given</h3>
- H is the circumcenter of triangle BCD,
- BC = 18
- HD = 14
<h3>To find </h3>
<h3>Solution</h3>
- Triangle BHD is isosceles, therefore BH = HD
- Point E is midpoint of BC, therefore BE = 1/2BC
<u>Using Pythagorean, finding the value of EH:</u>
- EH = √(BH² - BE²) = √(14² - (18/2)²) = √(196 - 81) = √115 = 10.72
Answer:
B, C, and [assumption] E.
Step-by-step explanation:
We are looking for an expression that is equal to -4(6). -4 * 6 = -24.
A. -4(-6)
-4 * -6 = 4 * 6 = 24
So, A does not have the same solution.
B. 4(-6)
4 * (-6) = -24
So, B has the same solution.
C. 6(-4)
6 * (-4) = -24
So, C has the same solution.
D. -8(2)
-8 * 2 = -16
So, C does not have the same solution.
E. 12(-2)
[I am not sure what number it is but I am <em>assuming</em> it is -2]
12 * (-2) = -24
So, <em>assumingly</em>, E has the same solution.
Hope this helps!
Answer:
width is 8, length is 32
Step-by-step explanation:
* = multiply or times
Let the width be x, then the length would be 4x
Perimeter = 2*length+2*width
80 = 2*4x+2*x
80 = 8x+2x
80 = 10x
8 = x (width)
32 = 4x (length)
The value of |-8.6| is 8.6 because absolute value is always positive
is undefined if the argument
is negative, so you first need to require that
We're not done yet, though, because

To find the range, consider the limits of the function as you approach either endpoint of the domain.
Since
