Answer:

\((f+g)(x)=f(x)+g(x)=4^{x} +12x+5x-1=4^{x}+17x-1\)

Answer:

4^x +17x -1

Step-by-step explanation:

F(x)=4^x+12x

g(x) = 5x-1

(f+g)(x)= 4^x +12x + 5x-1

     = 4^x +17x -1

a) 0.bar(36) expressed as a fraction in simplest form is 4/11. b) 0.3bar(6) expressed as a fraction in simplest form is 0.4. c) 0.36 expressed as a fraction in simplest form is 9/25.

(a)  To express 0.bar(36) as a fraction in simplest form, we can use the concept of repeating decimals. Let x = 0.bar(36). Multiplying x by 100 gives:

100x = 36.bar(36)

Subtracting the original equation from the multiplied equation eliminates the repeating part:

100x - x = 36.bar(36) - 0.bar(36)

99x = 36

x = 36/99

We can simplify this fraction by dividing both the numerator and denominator by their greatest common divisor, which is 9:

x = (36/9) / (99/9) = 4/11

Therefore, 0.bar(36) expressed as a fraction in simplest form is 4/11.

(b) o express 0.3bar(6) as a fraction in simplest form, let's call it x. Multiplying x by 10 gives:

10x = 3.6bar(6)

Subtracting the original equation from the multiplied equation eliminates the repeating part:

10x - x = 3.6bar(6) - 0.3bar(6)

9x = 3.6

x = 3.6/9

x = 0.4

Therefore, 0.3bar(6) expressed as a fraction in simplest form is 0.4.

(c) To express 0.36 as a fraction in simplest form, we can write it as 36/100 and simplify it. Both the numerator and denominator have a common factor of 4, so we can divide both by 4:

36/100 = 9/25

Therefore, 0.36 expressed as a fraction in simplest form is 9/25.

Answer:

Reflection across the x-axis: y = − f ( x ) y = -f(x) y=−f(x) The concept behind the reflections about the x-axis is basically the same as the reflections about the y-axis. The only difference is that, rather than the y-axis, the points are reflected from above the x-axis to below the x-axis, and vice versa.

the equation for g(x) after reflected over x axis and translated 4 units left

\(g(x)=-(x+4)^2\)

Given :

Parent function is \(f(x)=x^2\)

When a graph is reflected over x-axis then f(x)=-f(x)

When a graph is translated 'a' units left then we add 'a' with

f(x) becomes f(x+a)

Parent function f(x) is reflected over x-axis , multiply -1 with f(x)

so , \(f(x)=-x^2\)

Now we translate 4 units to the left, add 4 with x

\(g(x)=-x^2\\g(x)=-(x+4)^2\)

The final equation of g(x) is

\(g(x)=-(x+4)^2\)

Gail should pick a Beautiful bank if she plans to have her money in the account for 15 years.

To determine which bank would be better for Gail, we need to calculate the future value of her investment after 15 years for each bank and compare the results.

For Neighborhood Bank, we can use the formula:

FV = P(1 + r/n)^(n*t)

where FV is the future value,

P is the principal (the initial amount invested),

r is the annual interest rate (as a decimal),

n is the number of times the interest is compounded per year,

and t is the number of years.

Plugging in the values, we get:

FV = 5,500(1 + 0.012/1)^(1*15)

FV = 5,500(1.012)^15

FV = 7,130.34

For Beautiful Day Bank, we can use the formula:

FV = P(1 + r/n)^(n*t)

Plugging in the values, we get:

FV = 5,500(1 + 0.012/365)^(365*15)

FV = 5,500(1.000032876)^5475

FV = 7,145.25

Therefore, Beautiful Day Bank would be the better choice for Gail, as she would earn a higher amount of interest and end up with a higher future value for her investment after 15 years.

CenterWare's direct labor rate variance is $2,100 unfavorable, indicating that the actual rate paid for labor was higher than the standard rate. The direct labor efficiency variance is $2,500 favorable, suggesting that the company achieved higher productivity than expected. The total variance for direct labor is $400 favorable.

To compute the direct labor rate variance, we need to calculate the difference between the actual rate and the standard rate, and then multiply it by the actual hours worked. The formula for the rate variance is (Actual Rate - Standard Rate) × Actual Hours. In this case, the standard rate is $21.00 per hour, and the actual rate is $18.00 per hour. The actual hours worked are 2,500 DLH. Plugging in these values, we find the direct labor rate variance to be ($18.00 - $21.00) × 2,500 = -$7,500, indicating an unfavourable variance.

To calculate the direct labor efficiency variance, we need to find the difference between the actual hours worked and the standard hours allowed, and then multiply it by the standard rate. The formula for the efficiency variance is (Actual Hours - Standard Hours) × Standard Rate. The standard hours allowed are 2,000 DLH (1,000 pots × 2.0 hours per pot). Substituting the values, we get (2,500 - 2,000) × $21.00 = $10,500, indicating a favorable variance.

The total variance for direct labor is the sum of the rate variance and the efficiency variance. In this case, the total variance is -$7,500 + $10,500 = $3,000, which is favorable, indicating that the company performed better than expected in terms of labor cost and efficiency.

The responsibility for the rate variance generally lies with the purchasing department, as they are responsible for negotiating labor rates and purchasing materials at the standard price. The efficiency variance is typically the responsibility of the production department, as they are accountable for achieving the standard labor hours and maximizing productivity.

The rate variance reflects the difference between the actual rate paid for labor and the standard rate. An unfavorable rate variance suggests that the company paid more for labor than anticipated, which could be due to factors like higher wages or inefficient labor management. Conversely, a favorable rate variance would indicate cost savings in labor.

The efficiency variance measures the productivity of labor and represents the difference between the actual hours worked and the standard hours allowed. A favorable efficiency variance implies that the company achieved higher productivity or used fewer labor hours than expected. It could result from factors such as skilled and efficient labor, improved production processes, or effective workforce management.

The sales tax percentage is 10%.

What is a percentage?

A percentage is a way of expressing a proportion or a fraction as a number out of 100. It is often denoted with the symbol % (percent).

To find the sales tax percentage, we need to first find the amount of sales tax paid.

The amount paid with sales tax is $737, and the original price of the sculpture is $670. So the amount of sales tax paid is:

$737 - $670 = $67

To find the sales tax percentage, we divide the sales tax amount by the original price of the sculpture and then multiply by 100 to convert to a percentage:

($67 / $670) x 100% = 10%

Therefore, the sales tax percentage is 10%.

Answer:

False

Step-by-step explanation:

Yes, they do give vertical angles, which by definition means opposite angles created by intersecting lines. BUT, these angles are not supplementary, as they don't always complete eachother. If they were supplementary, they would not be vertical angles. Instead, they create CONGRUENT veritcal angles.

Hope this helped!

The statement is False which is intersecting chords do not form a pair of supplementary and vertical angles.

A chord of a circle is defined as the line segment whose both endpoints of that line are on the circumference of the circle.

Vertical Angles are the angles formed facing opposite to each other when two lines intersect each other.

Supplementary angles are the adjacent angles whose sum is 180° and together form a straight line.

So, here when two intersecting chords of the circle intersect each other at a point, they form two pairs of vertical angles, and according to the theorem of vertical angle, vertical angles are congruent.

As vertical angles are opposite to each other, so they can't be adjacent and can not form always 180° by adding their values and do not make straight line together.

But Intersecting chords of the circle can form a pair of congruent vertical angles.

So the given statement: Intersecting chords of a circle form a pair of supplementary, vertical angles is False.

1.5 x 10⁵

We use scientific notation to write huge ( or micro ) numbers as easily as possible. To do that, we use the following notation: a x 10ᵇ

Take 150,000, and put a decimal right between the 1 and 5, like so:

1.50000

Now simply count the numbers after the decimal:

1 . 5 0 0 0 0

    1  2 3 4 5

That's five places, or numbers, after the decimal, and now we can use the notion mention earlier, a x 10ᵇ

So a = 1.5 and b = 5, and now we can combine the whole thing, so 1.5 x 10⁵

We can double check if needed/desired by doing the following

10⁵ = 100,000 x 1.5 = 150,000

150000 is 1.5×10⁵ in scientific notation.

Scientific notation is a form of expressing large no. in compact form where the base (digit before the decimal) should be 1≤base<10.There after we multiply the base with powers of 10 to how much digits we have moved the decimal from rightmost side.

According to the given question
