Answer:
CDEF
Step-by-step explanation:
if the x value doesnt repeat then it is
On the line segment 
, 
depends only on 
:
Find the critical points of 
.
At this critical point, we have
Check the value of at the endpoints of the line segment.
So we have
Answer:
Use Pythagorean theorm.
a^2 + b^2 = c^2 (c is hypotenuse).
Let c = 5+b (because in the question it says the hypotenuse is one leg plus 5 more meters) ; we will solve for b and say it's the leg we don't know.
We will say A is the "other leg" we know, which is 6.
6^2 + b^2 = (5+b)^2
We get b = 1.1
Answer: 8
<u>Step-by-step explanation:</u>
x² - 2x + ___ - 4y² = 15 + ___
x² - 2x + <u> 1 </u> - 4y² = 15 + <u> 1 </u>
(x - 1)² - 4(y)² = 16
width of rectangle is 2
= 2(4) = 8
Answer:
Answer:
x = √70
Step-by-step explanation:
The triangles shown are all similar, so corresponding sides are proportional.
hypotenuse/long side = x/7 = (7+3)/x
Cross-multiplying gives ...
x^2 = 7(10)
x = √70
_____
You will note that the value of x (the long side) is the geometric mean of the long segment and the whole hypotenuse.
A similar "geometric mean" relation holds for the short side:
BC = √(CD·CA)
There is yet another "geometric mean" relation that holds for the altitude:
BD = √(CD·AD)
