4x+3y=7 x+2y=-2


put both in slope-intercept form

The logarithmic expansion of logs(20x + 5y) by using the properties of logarithmic is log(5)+log(4x+y).

The basic logarithmic function is of the form f(x) = logₐx(r)n = logₐx, where a > 0. It is the inverse of the exponential function aⁿ = x. Log functions include natural logarithm (ln) or common logarithm (log). Logarithmic functions is very useful in various mathematical computations.

Given that, log(20x+5y) and we have to expand it by using the properties of logarithms. So, let's proceed to solve the question.

log(20x+5y)

we can write 20 in terms of powers like 20 = (2²)x5

log((2².5)x+5y)

log(5(2².5x/5+5y/5))

log(5(2²x+y))

log(5(4x+y))

∵ log(ab) = log(a)+log(b)

⇒log(5(4x+y)) = log(5)+log(4x+y)

Hence, on expanding log(20x+5y) by using the properties of logarithms we get log(5)+log(4x+y) as our required answer.

The dimensions of the rectangular traffic sign whose perimeter is 134 inches according to the task content are; 38in by 29in.

It then follows that from the task content that the dimensions of the rectangular traffic sign are to be determined.

Since the perimeter of a rectangle is given by;

P = 2(l+b)

where the length, l = b +9.

So therefore; 134 = 2(b+9 +b)

134 = 4b + 18

4b = 134 - 18

4b = 116

b = 29

In conclusion, the length, l of the traffic sign is; 29 +9

l = 38.

Answer:

Here us the answer in the attachment

Answer:

the person above is correct

Step- by-step explanation:

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.

Answer: X = 8.4 Y= 3.5

Step-by-step explanation:

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.

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...

[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.

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

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%
= $57.52856

= $57.53

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

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 )

Therefore if f(x) = (4x² tan x)/sec x  then f'(x) = 4/(1+cos x) and f'(2) =2.00
