Answer:
The answer would be 18
Step-by-step explanation:
the formula for area of a triangle is 1/2b*h
so would mulitply 3*3 and get 9/2 which would be 4.5 do that on the otherside and you would get 4.5 again add together and you would get 9
for the square you would calculate the area by multplying b*h to get 9 so 9+9=18
The answer is 0.00010224...
Let's break it down so we can see the difference
Basic cable + 2 movie = $45.50
Basic cable + 1 movie = $39.00
since difference means to subtract...the difference is $6.50 for 1 movie channel.
subtract the 6.50 from the rate of 39.00 and we get the true cost of basic cable....$32.50
Answer:
The Volume is decreasing at a rate of per minute.
Step-by-step explanation:
Given a cone of radius r and perpendicular height h
Volume of the cone,
Since the height of the cone is fixed, the rate of change of the volume of the Cone, is given as:
We are to determine the rate of change of the Volume, V when:
The radius is decreasing at a rate of 2 cm per minute,
Height, h=9 cm
Radius = 13cm
The Volume is decreasing at a rate of per minute.
You would do y1-y2/x1-x2. So2--4/4-1
That equals 6/3=1/2 so the slope is 1/2
