Number of earthquakes decreased
Answer:
Step-by-step explanation:
3(n+4)=2n-8
3n+12=2n-8
5n= -20
n= -4
Remember, if the two graphs are symmetric with respect to the line y = x (mirror images over y = x ), then they are inverse functions. But, we need a way to check without the graphs, because we won't always know what the graphs look like! then f(x) and g(x) are inverse functions.
Answer:
The radius is 3.24102 meters
Step-by-step explanation:
We are given
area of mural is 33 m^2
Since, the shape of mural is circular
Let's assume radius of circle as 'r'
so, we can use area of circle formula
now, we can set A=33
and then we can solve for r
we get
So,
The radius is 3.24102 meters
Since they are similar, that means they are proportionally the same.
So KL is similar to PN
JL is similar to PM
So,
You need to find how much bigger is the second triangle from first.
It is proportionally scaled up.
KL/JL = PN/ PM
You basically put in order of triangles. Left triangle on left side of equal sign and right triangle on right side of equal sign. You put in denominator the similar sides and numerator the similar sides (the side that is similar to the side of the other triangle)
5/6 = PN / 9
Cross-multiply
PN * 6 = 5*9
6PN = 45
PN =45/6
PN =7.5
