Answer:
HC = 1
Step-by-step explanation:
AC = HC +AH = HC +(HC+2) = 2·HC +2
The altitude divides the triangle into similar triangles, so the ratio of hypotenuse to short side is the same for all. That is ...
BC/HC = AC/BC
2/HC = (2HC +2)/2
4 = 2(HC)(HC +1) . . . . . cross multiply
0 = HC² +HC -2 . . . . . . divide by 2, subtract 2
0 = (HC -1)(HC +2) . . . . factor. Solutions are those values of HC that make the factors be zero.
The useful solution is ...
HC = 1
Answer:y = 2x + 4
Explanation:
1) The slope - intercept form is of the kind y = mx + b, where m is the slope and b is the y-intercept.
2) Given two points you can find the slope (using the two points) and then the equation using one of the points.
3) slope = m = Δy / Δx
points given (3,10) , (0,4)
m = [y2 - y1] / [x2 - x1] = [10 - 4] / [3 - 0] = 6 / 3 = 2
4) equation
y - y2
-------- = m
x - x2
y - 4
---------- = 2
x - 0
=> y - 4 = 2 (x - 0)
y - 4 = 2x
y = 2x + 4
Answer:
<h2>The probability of first one to be blue is
.</h2>
Step-by-step explanation:
In the given box, there are 4 red markers and 2 blue markers.
The given scenario will not affect the required probability as the selection of the second one is a case of future.
We need to find the probability of the first marker is blue.
The probability is 
.
0.7037037037 is the 2(76)/6 to the third power
