(-5a)(-3a ²)
=
15a³
-5 x -3 = 15 ( negative times negative = positive)
a x a² = a³ ( when multiplying exponents, you add the exponents together )
Answer:
(600 miles) / (3 hours) = 200 miles/hour
= 321.8 km/h
So slope intercpet form
y=mx+b
m=slope
b=y intercpet
slope=5/3
in (x,y) form
x=3
y=5 is one point
subsitute and solve for b
y=mx+b
5=5/3 times 3+b
5=3/3 times 5+b
5=1 times 5+b
5=5+b
subtract 5 from both sides
0=b
equation is
y=5/3x+0 or
y=5/3x
The lateral surface area is the area of the side thing, not the 2 circles.
If we imagine to stretch the side out, we can get a rectangle with base the circumference to the base circle, and height of 9 inches.
Therefore this area is pi*8*9=72π
<h3><u>
Proportional.</u></h3>
The corresponding sides of similar figures can be equal, but if they are different in any way, they will always be proportional.
Corresponding angles, however, will always be equal.
