Answer:
radius = 5 units
Step-by-step explanation:
leg lengths of 6 and 8
AC = 6
BC = 8
Notice that since AB = diameter of circle and that C is inscribed in circle O
angle C = 90 degrees
triangle ABC is a right triangle
(AB )^2 = (AC)^2 + (BC)^2 by Pythagorean theorem
so
(AB)^2 = 6^2 + 8^2 = 36 + 64 = 100
AB = square root of 100 = 10
so AO = (1/2) *AB = (1/2)*10 = 5
Answer:
80%
Step-by-step explanation:
The basic idea of this problem is to convert
into a percentage.
can be simplified to
which is also 80%.
Answer:
X=10x =10
means here value of X is 1
y = 4y = 4
means here value of y is also 1
now substitute the values of X and y in the equation
8×1-7×1×(8×1-7×1)
8-7(8-7)
64-49
15
Answer:
y = -
x
Step-by-step explanation:
Given that x and y vary directly then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition x = - 4, y = 6, thus
k =
=
= - 
y = -
x ← equation of variation
