Answer and Explanation:
To find : Which number is in standard notation or scientific notation?
Solution :
Scientific notation is a special ways of writing the standard form of number.
Scientific notation make a big number into smaller way bye writing it into 10 to the power or using E.
Standard notation is like 12,47950585,89000.
Scientific notation is like 
, 
So, Now we examine the numbers,
A) 
is the Scientific notation.
B) 
is the Standard notation.
C) 
is the Scientific notation.
D) 
is the Standard notation.
(x + 9)(x + 12) = 0
Expanding the brackets, we get:
Answer:
the total price of the CD including tax is $11.984
Step-by-step explanation:
The computation of the total price of the CD including tax is shown below:
The Selling price of the CD is $14
CD is 20% off
And, the sales tax rate is 7%
So, the total price of the CD is
= ($14 - $14 × 20%) × (1.07)
= $11.2 × 1.07
= $11.984
Hence, the total price of the CD including tax is $11.984
Answer:
Step-by-step explanation:
From the figure attached,
If the figures shown are congruent (Equal in shape and size), length of all the sides must be equal.
Therefore, sides sides CD and GH must be equal in measures.
Distance between the two points 
and 
is given by,
d = 
Length of the side CD having ends C(-4, 4) and D(0, 5) will be,
CD = 
CD = 
= 
Length of GH having ends G(0, -4) and H(4, -5) will be,
GH = 
= 
=
Therefore, m(CD) = m(GH)
Similarly, we can prove all corresponding sides of two figures equal in measure.
This shows ABCD ≅ EFGH.
Answer:
1526.04 mm^2
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h where r is the radius and h is the height
V = 3.14 * (9)^2 *6
=1526.04 mm^2
