Answer:
see below
Step-by-step explanation:
Plot the points on the given graph. The ones that fall in on a solid line at the edge of the doubly-shaded area, or fall in the doubly-shaded area, are part of the solution set.
(0, 4) on the dashed line — not a solution
(-2, 4) on red line in blue area — solution
(0, 5) in doubly-shaded area — solution
(–2, 7) in doubly-shaded area — solution
(–4, 1) in blue area — not a solution
(–1, 1) on red line outside blue area — not a solution
(–1.5, 3.5) in doubly-shaded area — solution
175
explaination: simple math
A, C, E
B false because triangle is confirmed larger if the circle is fit inside of it.
D false because circle on the inside.
A true because triangle on outside
C true because it is a property of inscribed/circumscribed circles/triangles
E true because of inverse relationship
Answer: The base area, diameter, and radius can be found out by discovering the volume and height. Substitute the values to the corresponding variables into the formula, and then solve by simplifying and undoing operations to isolate the variable to find the diameter which is double the radius.
Answer:
The two numbers can be -12 and 11, or 11 and -12.
Step-by-step explanation:
xy=-132
x+y=-1
-------------
x=-1-y
(-1-y)y=-132
-y-y^2=-132
-y^2-y-(-132)=0
-y^2-y+132=0
y^2+y-132=0
factor out the trinomial,
(y-11)(y+12)=0
zero property,
y-11=0, y+12=0,
y=0+11=11,
y=0-12=-12
x+11=-1 & x+(-12)=-1
x=-1-11=-12
x=-1-(-12)=-1+12=11
