Answer:
(14n - 42)*pi
Step-by-step explanation:
Circumference is 2 * pi * r. Since r in this case is 7n - 21, you can multiply r by 2 and pi, giving you (14n - 42)*pi
Answer:
D) six hundred twenty-nine thousandths > six times one tenth plus three times one hundredth plus two times one thousandth
629000>8403 TRUE
Step-by-step explanation:
A) six times one tenth plus three times one hundredth plus two times one thousandth < six hundred twenty-nine thousandths
8,403.00
<629000 FALSE
B) six times one tenth plus three times one hundredth plus two times one thousandth = six hundred twenty-nine thousandths
8403= 629000 FALSE
C) six hundred twenty-nine thousandths < six times one tenth plus three times one hundredth plus two times one thousandth
629000<8403 FALSE
D) six hundred twenty-nine thousandths > six times one tenth plus three times one hundredth plus two times one thousandth
629000>8403 TRUE

Vertex<em> </em>is at 
<em>y-intercept</em> is 3.
The parabola <em>opens up</em>.
Step-by-step explanation:
The graph of the equation is hereby attached in the answer area.
Vertex is the point on the parabola where the graph crosses its axis of symmetry. The axis of symmetry here(
), is shown with the dotted line in the graph attached.
<em>y-intercept </em>is defined as the value of y where the graph crosses the y-axis. In other words, when
. Putting
And, the graph opens up as shown the graph figure as well. It is also evident from the co-efficient of
in the given equation
. Here, co-efficient of
So, vertex<em> </em>is at 
<em>y-intercept</em> is 3.
The parabola <em>opens up</em>.
Answer:
D. 19
Step-by-step explanation:
because they are parallel bases you can compare
63/57 = 21/x
x = 19
Answer:
Geometric Mean = 9.17
Step-by-step explanation:
Here,
a = 7
b = 12
Geometric mean = root(ab)
= root( 7 x 12)
= root(84)
= 9.17
