Answer:
first chart 27
second chart 6
Step-by-step explanation:
Hello there!
Surface Area = 4pir^2
First, we need to find our radius, since we have our diameter all we need to do is divide it by 2. That means, 10 divided by 2 equals 5.
Our radius is 5.
Now, we can plug it into the formula.
4(3.14)(5^2)
4(3.14)(25)
4(78.5)
4(78.5) = 314
Now, convert into pi.
314 = 100pi or 100Π
Answer:
Slope of the line segment PQ is 1/2.
Step-by-step explanation:
We are given with a line connecting two points P and Q.
The coordinates of P are (4,4) and the coordinates of Q are (-2,1).
Slope of line joining two points and
is given by the formula
Hence the slope of the line PQ is
Therefore correct option is 'C' that is 1/2.
Answer:
y = tan(x -π) -1
Step-by-step explanation:
It looks like a straight tangent function shifted down one unit. Since the tangent function has a period of π, ...
tan(x -π) = tan(x)
so you're only looking for the function that has a translation downward of 1 unit. Of course that translation is accomplished by adding -1 to the original function.
The appearance of the graph is of ...
y = tan(x) -1
The choice that is equivalent to this is ...
y = tan(x -π) -1
(x + 20)/2 = 3x
x + 20 = 2(3x) = 6x
6x - x = 20
5x = 20
x = 20/5 = 4
x = 4
