Answer:
1.4 cm²
Step-by-step explanation:
For this question, we can use formula - πr²(m/360). Here we are given m as 82 and r as 1.4cm. We can substitute values to get the area of the sector as approximately 1.4 cm²
Answer:3/4
Step-by-step explanation:
Multiply 1/6 by 2 to get 2/12 and then add that to 7/12 and get 9/12
If you simplify that you end up with 3/4
9514 1404 393
Answer:
y = 5x² -30x +39
Step-by-step explanation:
Multiply it out and collect terms.
y = 5(x -3)² -6
y = 5(x² -6x +9) -6 . . . . . expand the square
y = 5x² -30x +45 -6 . . . . use the distributive property
y = 5x² -30x +39 . . . . . . collect terms
_____
The expansion of a binomial square is ...
(a +b)² = a² + 2ab + b²
In this problem, we have a=x, b=-3.
Answer: The answers are in the steps hope it helps.
Step-by-step explanation:
First solve or the equation and let it be in slope intercept form
y + 2 = 1/2( x + 2) apply the distributive property first
y + 2= 1/2x + 1
-2 -2
y= 1/2x -1 is not in slope intercept form so you could put in any number for x and five y.
This are the points you could plot then draw a straight line between them.
