from the earth (in miles) is the star?
TL
miles from Farth
The distance of the earth from the star is; 1.416 x 10¹⁵ miles
What are exponents?The exponents of a number are defined as the representation of a number that shows how many times a number is multiplied by itself.
We are given that 1 light year ≈ 5.9 x 10¹² miles
so: the Coefficients for the problem are mathematically given a
Coefficients =2.4 x 5.9
Coefficients = 14.16
For Exponents;
Exponents= 10² x 10¹² = 10⁽²⁺¹²⁾
Exponents =10¹⁴
In conclusion, we put them together once again to produce a scientific notation;
14.16 x 10¹⁴
1.416 x 10¹⁵ miles
The distance of the earth from the star is; 1.416 x 10¹⁵ miles

Find the value of the following expression
(2^8 5^-5 19^0) x [5^-2 over 2^3]^4 x 2^28 (5 points)
Write your answer in simplified form. Show all of your steps. (5 points)
Looks like the expression is
(2⁸ • 5⁻⁵ • 19⁰) • (5⁻² / 2³)⁴ • 2²⁸
First, any positive number raised to 0 is 1:
(2⁸ • 5⁻⁵ • 1) • (5⁻² / 2³)⁴ • 2²⁸
(2⁸ • 5⁻⁵) • (5⁻² / 2³)⁴ • 2²⁸
Exponents in a denominator can be rewritten as negative exponents in the numerator:
(2⁸ • 5⁻⁵) • (5⁻² • 2⁻³)⁴ • 2²⁸
Distribute the 4th power across the product 5⁻² • 2⁻³ :
(5⁻² • 2⁻³)⁴ = 5⁻⁸ • 2⁻¹²
so we have
(2⁸ • 5⁻⁵) • (5⁻⁸ • 2⁻¹²) • 2²⁸
Multiplication is associative, so we can ignore the parentheses. Combine factors with equal bases and simplify the exponents:
2⁸ • 5⁻⁵ • 5⁻⁸ • 2⁻¹² • 2²⁸
2⁸⁻¹²⁺²⁸ • 5⁻⁵⁻⁸
2²⁴ • 5⁻¹³
Rewrite the negative exponent as a positive one:
2²⁴ / 5¹³
Which function has a domain of all real numbers?
A. y=-x½+5 B. y=(2x)⅓-7 C. y=(x+2)¼ D. y=-2(3x)⅙?
Answer:
B.
Step-by-step explanation:
B. Because the others have exponents whose denominators are even so the results of , for example x^1/2, if x is negative is not defined.
For example:
For A, when x is -4, (-4)^1/2 is not real.
For B, when x = -4, (2*-4)^ 1/3 = -8^(1/3) = = -2.

what is the equation for f(x)= |x| shifted to the right 3 units and Shifted down 4 units.
Answer:
The equation for f(x)=|x| if it is what is the equation for f(x)= |x| shifted to the right 3 units and Shifted down 4 units is f(x)=|x-3|-4
Step-by-step explanation:
We need to write equation for f(x)=|x| if it is what is the equation for f(x)= |x| shifted to the right 3 units and Shifted down 4 units.
When the graph is shifted towards right h units the equation becomes f(x)=(x-h) using it for our scenario:
If x is shifted right 3 units it will become f(x)=|x-3|
When the graph is shifted down h units the equation becomes f(x)=x-h using it for our scenario:
and Shifted down 4 units the equation will become: f(x)=|x-3|-4
So, the equation for f(x)=|x| if it is what is the equation for f(x)= |x| shifted to the right 3 units and Shifted down 4 units is f(x)=|x-3|-4
b. The total cost (1) after 8% sales tax is added to an item's price (p): 1.08p =
=f
Is there a proportional relationship
Answer:
No
Step-by-step explanation:
Yes, there is a proportional relationship between the total cost (f) after 8% sales tax is added and the item's price (p).
Here,
In this case, the total cost (f) is calculated by multiplying the item's price (p) by 1.08 (which is 100% + 8% sales tax in decimal form).
Mathematically, this can be represented as:
f = 1.08p
The equation shows that the total cost (f) is directly proportional to the item's price (p) with a proportionality constant of 1.08.
This means that as the item's price (p) increases, the total cost (f) will also increase proportionally by 8% due to the added sales tax.
Similarly, if the item's price (p) decreases, the total cost (f) will also decrease proportionally by 8%.
This relationship holds true for all values of p and f as long as the sales tax rate remains constant at 8%.
