Answer:
13.60
Step-by-step explanation:
use Pythagoras theorem
it is c²=a²+b²
c is hypotenus which is the longest side of a right angle triangle
--->now just put 8 on a and 11 on b
this gives us
c²= 8²+11²
c²= under the root 185
c² = 13.60147051
nearest hundredth is 13.60
hope you understood :)
Answer:
x = 13.60
Step-by-step explanation:
since it is a right angled triangle , we can use pythagoras theorem ,
hypotenuse^2 = base^2 + perpendicular^2
hypotenuse is the side opposite to the right angle .so here,
H = x .you can take base as 11 and perpendicular as 8
h^2 = p^2 + b^2
x^2 = 8^2 + 11^2
x^2 = 64 + 121
x =
x = 13.60

Step-by-step explanation:
4x² - 12x + 17 = 0
i is an imaginary number and it equals √-1, and you usually put it when the number under the root is negative.
So √-5 = √5i and √-4 = 2i
Those points you can see on the graph.
The first one refers to the x value and the second, to y value. If you notice, when you have x = 0, y = 3. When x = -5, y = 0.
When the line intercepts one of the axis, means the other coordinate is = 0.
3 is y intercept, it means the x value of that point is 0. The same happens to the x intercept - 5. It means the y value of that point is 0.
A ( -5 | 0 )
B ( 0 | 3 )
m = Delta y / Delta x.
Delta y is the variation over the x-axis. Delta x, the x axis.
Be safe!
