Answer: the area is 20 square centimeters.
Step-by-step explanation:
The area of an arc of angle x in a circle of radius r is:
A = (x/3.14)*3.14*r^2 = x*r^2
here we have x = (4/5)*3.14 and r = 5cm
Then the area is:
A = (4/5)*(5cm)^2 = 20cm^2
Answer:
The number 4 is the first term of the sequence
Step-by-step explanation:
we know that
<u>Counting backwards</u> is when the numbers are count in reverse sequence
Is also know as 1 less
In this problem the sequence of counting backwards from 5 is equal to
4,3,2,1,0
therefore
The number 4 is the first term of the sequence
Answer:
x=1.3288 or -1.1288
Step-by-step explanation:
Given 
Subtract 4x from both sides

Since we can factor out 2 from whole equation, let's factor out 2.

Divide with 2 on both sides

We got the quadratic equation, we can solve for x using quadratic formula.





Answer: C
Step-by-step explanation:
A monomial is a expression where in it is x to the power of something, and x cannot be a denominator
