Answer:
arc ≈ 5.5 units
Step-by-step explanation:
The arc of the circle is calculated as
arc = circumference of circle × fraction of circle
= 2πr × 
( r is the radius )
= 2π × 3.5 × 
= 
≈ 5.5 ( to the nearest tenth )
Answer:
Step-by-step explanation:
<u>Area of rhombus is:</u>
- A = pq/2, where p and q are diagonals
<u>We have:</u>
<u>The area is:</u>
- A = 18.3*13.8/2 = 126.27 ft²
Correct choice is C
Just get a calculator and do 18 divide by 4
A(n)=ar^(n-1) and we can find the rate upon using the ratio of two points...
50/1250=1250r^2/1250r^0
1/25=r^2
r=1/5 so
a(n)=1250(1/5)^1=250
...
You could have also found the geometric mean which is actually quite efficient too...
The geometric mean is equal to the product of a set of elements raised to the 1/n the power where n is the number of multiplicands...in this case:
gm=(1250*50)^(1/2)=250
None of your answers above will answer the question. The proper value for x = 1/2 is 7/4. The work for this is below.
f(x) = 3x^2 + 1
f(1/2) = 3(1/2)^2 + 1
f(1/2) = 3(1/4) + 1
f(1/2) = 3/4 + 1
f(1/2) = 7/4
I assume you may have missed something in typing, but 7/4 would be your answer.
