Step-by-step explanation:
here is the answer babe. Feel free to ask for more help
Answer:
A) 2341 square units
Step-by-step explanation:
Area of a regular polygon= 1/2*perimeter*apothem
Perimeter=22*8=176 units
Apothem=26.6 units
Thus:
A=1/2*176*26.6
A=88*26.6
A=2340.8
So the area of the regular octagon rounded to the nearest square unit is 2341 units^2, aka. Option A
Answer:
B
Step-by-step explanation:
Because two sides of the triangle are the same length
Answer:
2/3 in 3/4 of an hour. that would mean u an extra 1/4 of an hour would give Katie the time to finish up the project
Step-by-step explanation:
Katie, take no breaks when u can get this done in an hour. don't be lazy
First, write the equation of the line containing the points <span>(2,-5) and (-3,2).
We can use 2 point form, or point-slope form.
Let's use </span>point-slope form.
the slope m is

, then use any of the points to write the equation. (ex, pick (2, -5))
y-(-5)=(-7/5)(x-2)
y+5=(-7/5)x+14/5
y= (-7/5)x+14/5 - 5 =(-7/5)x+14/5 - 25/5 =(-7/5)x-11/5
Thus, the lines are
i) y=-ax+4 and ii) y=(-7/5)x-11/5
the slopes are the coefficients of x: -a and (-7/5),
the product of the slopes of 2 perpendicular lines is -1,
so
(-a)(-7/5)=-1
7/5a=-1
a=-1/(7/5)=-5/7
Answer: -5/7
