Answer:
D. Kailey is not correct: 
is not written in scientific notation.
Step-by-step explanation:
We have been given that Kailey wrote 8,912,000 in scientific notation as . We are asked to choose the statement that best describes Kailey's work.
We know that to convert a number into scientific notation, we write the given number as product of two numbers. One factor is a number between 1 and 10, while the 2nd factor is power of 10.
Upon looking at , we can see that 1st factor is 89.10, which is greater than 10. This means that Kailey did not write 8,912,000 in scientific notation.
Therefore, option D is correct choice.
Answer:
9.82 inches²
Step-by-step explanation:
both areas are equally sized, so they are both half of the whole circle.
circle area : pi × r²
half of the circle area is therefore pi × r² / 2
the picture gives us the diameter of the circle, the radius is half of the diameter.
=> r = 5/2 = 2.5
=> shaded area = pi × r² / 2 = pi × (2.5)² / 2 = 9.82 inches²
Answer:
k = 4
Step-by-step explanation:
In order for the claim to be true, (x-3) must be a factor of each of the terms in the first expression. That is, you must have that expression factor as ...
(x -3)(2x +5) +(x -3)(x +7)
Factoring out (x -3), we get ...
= (x -3)(2x +5 +x +7) = (x -3)(3x +12)
= 3(x -3)(x +4)
The value of k must be 4.
No way to tell . . . . . we can't see the chart below.
It must be WAY down there where the sun don't shine.
The logarithmic model for the length when the strength is of 8 Pascals is given by:
- That is, the length is of 3 units.
<h3>What is the function?</h3>
The strength in Pascals for a building of length x is given by:
To find the length given the strength, we apply the inverse function, that is:
Hence, when the strength is of 8 Pascals, 
, and the length is given by:
