You will find the area of the semicircle by finding the area of the circle with a radius of 8.5 mm and the dividing it by 2.
A = pi x r^2
3.14 x 8.5^2
A = 226.865 square mm
226.865/2
113.43
The approximate area of the semi circle is 113.43 mm².
Answer:
The rate of change is -5
The initial value is 25
Step-by-step explanation:
Since, this is a linear relation
so, we can select any two points and find equation of line
points are (1,20) and (3,10)
so,
now, we can find slope
now, we can plug values
now, we can use point slope form of line
now, we can plug values
now, we can solve for y
we know that
slope is the rate of change
So, the rate of change is -5
For finding initial value , we can plug x=0 and find y
So, initial value is 25
Answer:
The 29th term is
<h2>243</h2>
Step-by-step explanation:
The above sequence is an arithmetic sequence
For an nth term in an arithmetic sequence
U(n) = a + ( n - 1)d
where n is the number of terms
a is the first term
d is the common difference
From the question
a = - 121
d = -108 -- 121 = - 108 + 121 = 13
Since we are finding the 29th term
n = 29
The 29th term of the sequence is
U(29) = - 121 + ( 29 - 1) 13
= -121 + 28(13)
= -121 + 364
The final answer is
<h2>243</h2>
