Answer:
y + 6 = (x - 4)
Step-by-step explanation:
the equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
here m = and (a, b ) = (4, - 6 ) , then
y - (- 6) = (x - 4) , that is
y + 6 = (x - 4)
Answer:
−0.0005 m/sec.
Step-by-step explanation:
Let us denote the volume of the can as V
let us denote the radius of the circular disc in lake as r
Let us denote the thickness of the circular disc as h
But we know the volume of the can as πr^2h then we can calculate How fast it is decreasing when the radius is 2 m

PART A - So the ruler is 22.86 centimeters tall, and after measuring with an inch ruler, is also 9 inches tall.
ruler = 22.86cm
ruler = 9 in
You can equate 22.86cm and 9in because they both equal the length of the ruler (transitive property).
22.86cm = 9in
Then you can write a proportionality equation.
Part B -
Cross multiplying,
Part C - We can use something called dimensional analysis - multiplying 12 cm by (1in/2.54cm) - in order to change the units from inches to cm. This is possible because 1in = 2.54cm, the fraction 1in/2.54cm = 1. And also the units cm will cancel out.
The simplified form is: =4p2−18p+8
Step by Step:
(4p−2)(p−4)
=(4p+−2)(p+−4)
=(4p)(p)+(4p)(−4)+(−2)(p)+(−2)(−4)
=4p2−16p−2p+8
=4p2−18p+8
Number 14 is A because the formula for finding the area in a trapezoid is base1 + base2 x hight divided by 2
