Answer:
First figure is regular and convex.
Second figure is irregular and convex.
Step-by-step explanation:
Here given 2 polygons we have to classify these whether these are convex, concave, regular and irregular.
Regular Polygon is the polygon which have all sides and all angles equal.
Convex Polygon is the polygon in which measure of all interior angles less than 180° and if measure of each of interior angle greater than 180° then it is concave.
In the first figure, all sides are equal therefore and each of interior angle of polygon is less than 180°. Hence, the polygon is regular and convex.
In the second figure, all sides are not equal and each of interior angle of polygon is less than 180°. Hence, the polygon is irregular and convex.
Dont mind the sign until fourth step
First step: find divisibles of 90
1,2,3,5,6,9,10,15,18,30,45,90
Second step:find the pairs
1*90,2*45,3*30,5*18,6*15,9*10
Third step: find which one has a difference of 5
None of them is (expand this question more so i can help you)
Answer:
-4
Step-by-step explanation:
9^2+19/(10^2-5^3)
9^2+19/(10^2-5^3)=81+19/100-125
9^2+19/(10^2-5^3)=81+19/100-125=100/-25
9^2+19/(10^2-5^3)=81+19/100-125=100/-25= -4
Easy, subsitute a point
we see it goes through (0,4)
so subsitte 0 for x and see if we get 4
4^0=1, nope
4^0-3=1-3=-2, nope
4^0+3=1+3=4, yep
4^(0+3)=4^3=64, noe
answer is 3rd option
f(x)=4^x+3
