Answer:
51.9 cm²
Step-by-step explanation:
From the diagram attached,
Area of the white region(segment)(A) = Area minor sector- area of the triangle
A = (πr²∅/360°)-(1/2r²sin∅)............... Equation 1
Where r = radius of the circle, Ф = reflex angle formed at the center of the circle, π = pie
From the question,
Given: r = 7 cm, Ф = 150°
Constant: π = 22/7
Substitute these values into equation 1
A = [(22/7)×7²×150/360]-[(1/2)×7²×sin150]
A = 64.17-12.25
A = 51.92
A = 51.9 cm²
Answer: -216
Step-by-step explanation:
To solve the exercise you must use the formula shown below:
Where:
You should find 
The formula to find it is:
Where d is the difference between two consecutive terms.
Then:
Substitute it into the first formula. Therefore, you obtain:
Answer:j
Step-by-step explanation:
If it’s closed it would be greater than -2 but since it’s open it’s equal or greater than
Let's solve ~
It's factorized now ~ And if you want to find the zeros then equate the expression with 0.
And you will get ;
4 (3n-2) is the answer.
Woops. Sorry I had no idea that it said expression (s) instead of expression, but that is one of the answers though.
