We are given
length of sides are
AB=7
AC=7
BC=6
now, we can use formula of area of triangle
where
A is area of triangle
r is radius of in-circle
s is semi-perimeter of triangle
step-1: Finding area of triangle
We can use
Heron's formula
a , b and c are values of sides
now, we can plug values
step-2: Finding radius(r)
we got
now, we can find radius

Answer:
Center is (7,-6)
Our radius is 4
Step-by-step explanation:
Subtract 69 to both sides
Complete the square of the x terms and y terms.
(To complete the square divide the coefficient by 2 and square it).
Add those terms to the full equation. Add 36 and 49 to the right side as well
Simplify the x and y terms into a binomial.
Set the left side equal to zero separately to find the center and take the square root of the right side to find the radius.
So our center is (-7,6)
Our radius is 4.
Answer:
Since the values vary from 0.5 to 4.5, let's take 5 intervals of width 1 unit each
(Lower boundary is included, upper boundary is not)
Average
no. of --------> frequency

_______ __________
0 - 1 --------------> 1
1 - 2 --------------> 5
2 - 3 --------------> 5
3 - 4 --------------> 2
4 - 5 --------------> 1
For frequencies, just count the data values in each interval
Answer:
10%
Step-by-step explanation:
24.97 - 22.70=2.27
Increased price÷initial price×100%
2.27÷22.70×100%=10%
