The numbers as a single digit times a power of ten are ; 1. 4x10^-9, 2. 4x10^10, 3. 5x10^7, 4. 2x10^-5
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division. The Numbers constants, variables, operations, brackets can all be represented by mathematical symbol; which can also be used to indicate the logical syntax's order of operations and other features.
Therefore, each number as a single digit times a power of ten.
1. 0.000000043 is [tex]4 \times 10^{-9}[/tex]
2. 43560000.000 is[tex]4 \times 10^{10}[/tex]
3. 56.234567 is [tex]5 \times 10^7[/tex]
4. 0.00002346 is [tex]2 \times 10^{-5}[/tex]
Hence, The numbers as a single digit times a power of ten are ; 1. 4x10^-9, 2. 4x10^10, 3. 5x10^7, 4. 2x10^-5

A rectangle lengths 12m and 17m and is dilated using the dilation (x, y) -> ( 0.4 x, 0.4y). What is the perimeter of the dilated rectangle?
Answer:
Perimeter of the dilated rectangle = 23.2 m
Step-by-step explanation:
If a point is dilated by a scale factor = k
Coordinates of the image point after dilation will follow the rule,
(x, y) → (kx, ky)
From the given rule,
(x, y) → (0.4x, 0.4y)
Which reveals that the figure has been dilated by a scale factor = 0.4
Length of the rectangle = 12 m
Width of the rectangle = 17 m
If the given rectangle is dilated by a scale factor of 0.4,
Length of the image rectangle = 12 × 0.4 = 4.8 m
Width of the image rectangle = 17 × 0.4 = 6.8 m
Perimeter of a rectangle = 2(length + width)
Therefore, perimeter of the image rectangle = 2(4.8 + 6.8)
= 23.2 m
Find the error & explain why it is wrong:
Laural had to find the average rate of change of f(x) over the interval from x = 6 to x = 10 using the table below.
What did she do wrong?
Step b is wrong. The slope is the change in y over the change in x.
Step b should be (18- 8)/( 10-6)
= 10/4

What is the surface area of the cylinder?
226.08 cm²
678.24 cm²
1,356.48 cm²
452.16 cm²
Answer:
452.16
Step-by-step explanation:
i got it right on test
The surface area of the cylinder is,
⇒ TSA = 452.16 cm²
We have to given that;
Height of cylinder = 6 cm
And, Diameter of cylinder = 12 cm
Hence, We get;
⇒ Radius of cylinder = 12 / 2 = 6 cm
We know that;
The formula for the total surface area of a given cylinder whose radius is r and height is h is,
TSA = 2πr (h + r)
Hence, We get;
TSA = 2πr (h + r)
TSA = 2 × 3.14 × 6 (6 + 6)
TSA = 37.68 × 12
TSA = 452.16 cm²
Thus, The surface area of the cylinder is,
⇒ TSA = 452.16 cm²
