Answer:
The radius of the circle is approximately 14.42cm
Step-by-step explanation:
If the length of the chord is 16cm and it is 12cm from the center of the circle.
it means it forms 2 right angles while dividing the center of the chord, to the center of the circle, and at right angle. Length of the adjacent then become 16/2 = 8cm
To calculate the radius which forms hypothenus of the right angle triangle, we use Pytagoras Theorem
Say = + , where r is the radius of the circle
= 144 + 64
= 208
r =
r = 14.4222
r ≈ 14.42
Answer:
Step-by-step explanation:
Given the expression
Apply the distributive law
Thus, we conclude that
Answer:
7
Step-by-step explanation:
The order of operations tells you to start any evaluation by looking at the innermost set of parentheses first.
Here, that means your first step is to find the value of h(-3). You do that by finding the input (x) value -3 in the table for h(x), and locating the corresponding output, h(x), which is 2.
Now, the problem becomes evaluating g(2).
You do the same thing for that function: locate the input x=2 in the table for g(x) and find the corresponding output: 7.
Now, you know ...
g(h(-3)) = g(2) = 7
Answer:
24 units
Step-by-step explanation:
Note that BC is one side of the square. (Vertices are in order ABCD)
So, as a square has four equal sides, the perimeter is 4 times the length of BC.
We're given B is at (-2, 5) and C is at (4, 5). So, BC = 6 units.
So, the perimeter of ABCD is 6 * 4 = 24 units.
