Answer:
-63
Step-by-step explanation:
This arithmetic progression
The formula is a+(n-1)d
a means the first value
n is the nth term
d is the difference
So a is -5
n is 30
d is -2
So let's substitute
-5+(30-1)-2
-5+(29)-2
-5-58
-63
Therefore the final answer is-63
Just follow the step and the general formula, you will get your final answer
Answer:
56cm, y=5x+6
Step-by-step explanation:
The baby panda's initial or starting length is 5cm. This is the y-intercept or b value. We also know that the panda increases every week by 5 cm. This is the rate of change or slope. This is m. We can write in slope-intercept form y=mx+b.
y=5x+6
We substitute x=10. y=5(10)+6=56cm
In regular polygons, if the number of sides, n, is odd, the lines of symmetry will pass through a vertex and the half of the opposite side.
Step-by-step explanation:
This is equivalent to say that a perpendicular bisector of a side of the regular polygon bisects the angle of the opposite vertex to the side, and divide the polygon into two symmetrical parts.
