Enter the correct answer in the box.
6.355x10^10
Step-by-step explanation:
Scientific notation is the way of writing a large number between 1 to 10 with a power of 10.
The scientific notation of 63,550,000,000 is 6.355 x [tex]10^{10}[/tex].
What is scientific notation?It is the way of writing a large number between 1 to 10 with a power of 10.
Example:
2.3 x 10² is a scientific notation of 230
9.1 x 10³ is a scientific notation of 9100
We have,
63,550,000,000
We can write this as,
6355 x [tex]10^{7}[/tex]
We need to make a number between 1 and 10.
So,
Divide and Multiply 1000.
6355/1000 x [tex]10^{7}[/tex] x 1000
6.355 x [tex]10^{10}[/tex]
We see that,
6.355 is a number between 1 and 10 with a power of 10.
Thus,
The scientific notation of 63,550,000,000 is 6.355 x [tex]10^{10}[/tex].

Answer:
A. x = 6.08, x = -0.58
Step-by-step explanation:
[tex]\displaystyle \frac{2x}{x-4}-\frac{2x-5}{x^2-10x+24}=\frac{-3}{x-6}[/tex]1. Factor the denominator.
[tex]\displaystyle \frac{2x}{x-4}-\frac{2x-5}{(x-6)(x-4)}=\frac{-3}{x-6}[/tex]2. Multiply the leftmost fraction by (x-6)/(x-6) to get common denominators.
[tex]\displaystyle \Big ( \frac{x-6}{x-6} \Big ) \frac{2x}{x-4}-\frac{2x-5}{(x-6)(x-4)}=\frac{-3}{x-6}[/tex]3. Simplify.
[tex]\displaystyle \frac{2x^2-12x}{(x-4)(x-6)}-\frac{2x-5}{(x-6)(x-4)}=\frac{-3}{x-6}[/tex]4. Combine like terms.
[tex]\displaystyle \frac{2x^2-14x+5}{(x-4)(x-6)}=\frac{-3}{x-6}[/tex]5. Multiply the right side of the equation by (x-4)/(x-4).
[tex]\displaystyle \frac{2x^2-14x+5}{(x-4)(x-6)}=\frac{-3}{x-6} \Big ( \frac{x-4}{x-4} \Big )[/tex]6. Simplify.
[tex]\displaystyle \frac{2x^2-14x+5}{(x-4)(x-6)}=\frac{-3x+12}{(x-6)(x-4)}[/tex]7. "Cancel" out the denominators because they are equivalent.
[tex]2x^2-14x+5=-3x+12[/tex]8. Set the equation equal to 0.
[tex]2x^2-11x-7=0[/tex]Quadratic formula:
[tex]\displaystyle x = \frac{-b\pm \sqrt{b^2-4ac} }{2a}[/tex]9. Factor using the quadratic formula.
[tex]\displaystyle x = \frac{-(-11)\pm \sqrt{(-11)^2-4(2)(-7)} }{2(2)}[/tex]10. Multiply and simplify.
[tex]\displaystyle x = \frac{11 \pm \sqrt{177} }{4}[/tex]11. Plug this into your calculator and solve for x.
[tex]x=6.07603367 \approx 6.08[/tex] [tex]x=-0.57603367 \approx -0.58[/tex]The correct answer is A. x = 6.08, x = -0.58.

Which of the following shows exponential growth rate of 7%?
Group of answer choices
LaTeX: A=325\left(1.07\right)^tA = 325 ( 1.07 ) t
LaTeX: A=325\left(0.93\right)^tA = 325 ( 0.93 ) t
LaTeX: A=325\left(0.07\right)^tA = 325 ( 0.07 ) t
LaTeX: A=325\left(1.7\right)^t
Answer:
A=325(1.07)^t
Step-by-step explanation:
I got an 100 on the test
[tex]A=325(1.07)^t[/tex]shows the exponential growth rate of 7%
What is a function?A relation is a function if it has only One y-value for each x-value.
The formula for exponential growth is given by:
[tex]A = P(1 + r)^t[/tex]
where A is the amount after t periods, P is the initial amount, and r is the rate of growth.
To represent a growth rate of 7%, we can use:
[tex]A = 325(1 + 0.07)^t[/tex]
Hence, [tex]A=325(1.07)^t[/tex] shows the exponential growth rate of 7%

A cylinder has a base diameter of 20in and a height of 17in. What is its volume in cubic in, to the nearest tenths place?
Step-by-step explanation:
(3.1415 * 10^2) area of base
(17) height
volume = area of base * height
volume = 3.1415 * 10^2 * 17
The volume of the cylinder is 533.8 cubic inches to the nearest tenths place
Volume of Cylinder based problem:What information do we have?
Diameter of cylinder = 20 inch
Height of cylinder = 17 inch
Volume of Cylinder = πr²h
Volume of Cylinder = (3.14)(20/2)²(17)
Volume of Cylinder = (3.14)(10)(17)
