[tex]\frac{5.025 \times 10^{10}}{1.5 \times 10^{8}} \\ \\ =\frac{5.025}{1.5}(100) \\ \\ =\boxed{335}[/tex]
Option A is correct, 5.025 x 10¹⁰ is 335 times larger than 1.5 x 10⁸.
To determine how many times larger one number is than another, we divide the larger number by the smaller number.
In this case, we want to find how many times larger 5.025 x 10¹⁰ is than 1.5 x 10⁸.
Dividing the larger number by the smaller number:
(5.025 x 10¹⁰) / (1.5 x 10⁸)
To simplify, we can divide the coefficients (5.025 / 1.5) and subtract the exponents (10¹⁰ - 10⁸):
(5.025 / 1.5) x 10¹⁰⁻⁸
Evaluating the division of the coefficients:
(3.35) x 10²
Therefore, 5.025 x 10¹⁰ is 3.35 x 10² times larger than 1.5 x 10⁸.
In decimal form, this can be expressed as:
3.35 × 10² = 335
Therefore, 5.025 x 10¹⁰ is 335 times larger than 1.5 x 10⁸.

If f(1)=6f(1)=6 and f(n)=f(n-1)-2f(n)=f(n−1)−2 then find the value of f(6)
The value of function f(n) = f(n - 1) - 2, at n = 6 is f(6) = -4
In this question,
we have been given a function f(n) = f(n - 1) - 2
Also, we have been given the value of function f(n) for n = 1
i.e., f(1) = 6
We need to find the value of f(6).
For n = 2,
f(2) = f(2 - 1) - 2
f(2) = f(1) - 2
f(2) = 6 - 2
f(2) = 4
For n = 3,
f(3) = f(3 - 1) - 2
f(3) = f(2) - 2
f(3) = 4 - 2
f(3) = 2
For n = 4,
f(4) = f(4 - 1) - 2
f(4) = f(3) - 2
f(4) = 2 - 2
f(4) = 0
For n = 5,
f(5) = f(5 - 1) - 2
f(5) = f(4) - 2
f(5) = 0 - 2
f(5) = -2
For n = 6,
f(6) = f(6 - 1) - 2
f(6) = f(5) - 2
f(6) = -2 - 2
f(6) = -4
Therefore, the value of function f(n) = f(n - 1) - 2, at n = 6 is f(6) = -4

Write equation in slope-intercept form (9,-5) slope -4/3
The equation of the line in slope intercept form is y = (-4/3)x + 7.
According to the slope intercept form, the equation of a line is given as-
y = mx + c
where m is the slope and c is the y intercept.
Here we are given that an equation passes through the point (9,-5) and has a slope of -4/3.
According to the point slope form, the equation of a line passing through (x1, y1) and slope m is given as-
(y - y1) = m(x - x1)
Here,
x1 = 9, y1 = -5 and m = -4/3
Thus,
(y + 5) = -4/3(x - 9)
3(y + 5) = -4(x - 9)
3y + 15 = -4x + 36
3y = -4x + 21
y = (-4/3)x + 21/3
y = (-4/3)x + 7
This is our equation in slope intercept format as m = -4/3 and c = 7
Thus, the equation of the line in slope intercept form is y = (-4/3)x + 7.

For the function f(x) =(4 sin x)/(1+cosx) , then f'(x) = 4/(1+cosx) using quotient rule of differentiation and f'(2) = 2.00
What is quotient rule for differentiation?Quotient rule for differentiation states that the differentiation the division of two functions u, v is given as
(u/v)' = (u' v - u v')/v² , where ' represents first derivative with respect to independent variable
Given f(x) = (4sinx)/(1+cosx)
let u =4 sin x , v = 1+cos x , u'=4cos x , v' = -sin x
Then f(x) =u / v
Using quotient rule of differentiation:
f'(x) = ( u' v -u v' )/v² = (4cosx(1+cosx) +4sin²x )/(1+cos x)²
f'(x) = = 4(cos x +cos² x +sin² x)/(1+ cos x)² = 4(cos x +1)/(1+ cos x)²
f'(x) = 4/(1+ cos x)
To find value of f'(x) at x= 2
f'(5) = 4/(1+cos2) = 2.000609= 2.00(rounding off )

Convert the angle to a decimal in degrees.
16°43'27"
The value of the angle 16°43'27"is approximately 16.724167 degrees.
A plane angle is measured in degrees, with the letter ° typically used to indicate that one full rotation is equal to 360 degrees.
The radian is the SI unit for measuring angles.1 degree = [tex]\frac{\pi}{180}[/tex] radiansA complete rotation around a circle is 180°.A degree is a narrow enough angle for many practical tasks where full degrees are enough for precision. In those instances when this is not the case, such as in astronomy or for geographic coordinates (latitude and longitude), degree measurements may be expressed in decimal degrees.To convert a degree from minutes and seconds to decimal we must know the relation between degree and minutes and seconds.
1 degree=60 minutes.
1 minute = 60 seconds.
The given angle is 16°43'27"
27 seconds = 27 ÷ 60 minutes = 0.45 minutes = 0.45 ÷ 60 degree =0.0075 degree
43 minutes= 43 ÷ 60 degree = 0.71666666..
Total angle in decimal = 16+0.71666666+0.0075 =16.7241666...
Therefore required angle ≈ 16.7241667 degrees.

Based on the gross pay to Edie of $927.88, the amount contributed by Edie Social Security was $57.53 and the amount to Medicare was $13.45
How to find contribution to social security?The current Social Security tax rate is 6.2% which means that to find the Social Security tax that Edie will contribute will be:
= Social security tax rate x Gross pay of Edie
= 927.88 x 6.2%

The required solution to the equation 4x^3 + 16x^2 + 28x = 0 is 0, -2 + i√3, -2 - i√3
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .
Now the given equation is,
4x^3 + 16x^2 + 28x = 0
Taking x common we get,
x(4x^2 + 16x + 28) = 0
So, we get
x = 0
And 4x^2 + 16x + 28 = 0
or, x^2 + 4x + 7 = 0
Thus from the above equation is of the form
ax^2 + bx + c = 0
where, a = 1, b = 4 and c = 7
Therefore solution of the above equation is given as,
x = [-b ± √(b^2 - 4ac)] / 2a
Putting the values we get,
x = [-4 ± √(4^2 - 4*1*7)] / 2*1
so, x = [-4 ± √(16 - 28)] / 2
x = [-4 ± √(- 12)] / 2
x = [-4 ± 2√(- 3)] / 2
or, x = [-2 ± √(- 3)]
Since √-1 = i
∴ √(- 3) = i√3
Thus,
x = -2 ± i√3
So, the required values of x are 0, -2 + i√3, -2 - i√3.
Thus, the required solution to the equation 4x^3 + 16x^2 + 28x = 0 is 0, -2 + i√3, -2 - i√3.
