4 x 7= 28
BTW no calculator. Did it in my head. Hope this helps!
Answer:
D. 42 units
Step-by-step explanation:
The perimeter of the rectangular shown on the coordinate plane = sum of all it's four sides
= 2(length + width)
Length = 11 units
Width = 10 units
Plug in the values
Perimeter = 2(11 + 10)
= 2(21)
= 42 units
Does not exist, since the graph of cosine is continuous between the intervals [-1,1]. You do not know where it will be when it “reaches” infinity
Answer and explanation for second picture…good luck… (my hand writing is kind of trash)
Slope intercept form is y=mx+b
Y= y intercept
M = slope
B = x intercept
-2x-11y= 5 get the y by itself
-11y = 2x + 5 divide by -11
y = -2/11x + 5/11
slope is -2/11
