Ngozi earns $24,000 in salary in the first year she works as an interpreter. Each year, she earns a 3.5% raise.

Step-by-step explanation:

Domain: The domain of the function is all real numbers.

Range: The range of the function is all real numbers less than or equal to 8. To see this, note that the leading coefficient of the polynomial is negative (-x^3), so the function approaches negative infinity as x approaches positive or negative infinity. The largest y-value the function can attain is 8, which occurs at x = 2.

Relative maxima and minima: To find the relative maxima and minima, we find the critical points of the function, which are the values of x that satisfy f'(x) = 0 or f'(x) does not exist. The first derivative of the function f(x) is given by:

f'(x) = -3x^2 + 16x - 15

Solving f'(x) = 0, we get:

-3x^2 + 16x - 15 = 0

x = 1, 5

We also need to determine the concavity of the function near each critical point to determine whether each is a relative maximum or minimum. To do this, we find the second derivative of the function and evaluate its sign at each critical point. The second derivative of f(x) is given by:

f''(x) = -6x + 16

Since f''(x) is always negative, the function is concave down and therefore has a relative maximum at x = 1 and a relative minimum at x = 5.

End behavior: The leading term of the function is -x^3, which means the function approaches negative infinity as x approaches negative infinity and positive infinity as x approaches positive infinity. The end behavior of the function is therefore negative infinity as x approaches negative infinity and positive infinity as x approaches positive infinity.

Increasing and decreasing intervals: To find the increasing and decreasing intervals of the function, we find the critical points and the sign of f'(x) in the intervals between the critical points.

f'(x) = -3x^2 + 16x - 15

Since f'(x) is negative for x < 1 and positive for x > 1, the function is decreasing for x < 1 and increasing for x > 1. Similarly, since f'(x) is positive for x < 5 and negative for x > 5, the function is increasing for x < 5 and decreasing for x > 5. So, the increasing intervals are (negative infinity, 1) and (1, 5) and the decreasing intervals are (5, positive infinity).

Step-by-step explanation:

15% = 0.15 x 37 = 5.55$ off the original price so 31.45$ is the final price for the tee shirt. Give brainlist please

Sale price for the given shirt will be $32.

According to question given are-

Percentage of the reduction rate of the shirt is = 15%

Reduction Percentage refers to the percentage rate at which the Initial Per Certificate Entitlement will diminish daily, assuming that the daily rate will be calculated as the annual rate given in the Final Terms divided by 365 and applied as necessary.

Actual cost of the shirt is = $37.

decreased rate "Reduced rate" refers to a contribution rate that is lower than the standard rate required by State law, while "standard rate" refers to the rate used to compute variances from that rate.

So, accordingly Reduction rate = (Actual rate X Reduction Percentage)/100

Reduction = (37×15)/100 = Rs 5.55$ ≅ 5$

So the sale price = 37−5 = 32$

The given assertion states that the sequence's nth element is -k² + (2n-3)k + 1.

Sequential is a derivative of the Latin word consecutus, which means "following closely" without a pause. Similar to those snowstorms, which occurred back-to-back each day for five months in a succession. Additionally, consecutive numbers progress in the correct sequence or follow one another. For instance, the numerals 5, 6, 7, 8, 9, and 10 follow one another.

Looking at the differences between consecutive terms, we have:

(k+2) - (-k²-k+1) = k²+3k+3 - (k+2) = k²+2k+1 = (k+1)²

(k²+3k+3) - (k+2) = k²+2k+1 = (k+1)²

(2k²+5k+4) - (k²+3k+3) = k²+2k+1 = (k+1)²

We can see that the differences between consecutive terms are all the same, which means that the sequence is an arithmetic sequence.

To find tₙ, we need to find the common difference d. From the differences above, we have:

d = (k+1)² - (k²+k-1) = 2k

So, the nth term of the sequence is given by:

tₙ = t₁ + (n-1)d

tₙ = (-k²-k+1) + (n-1)(2k)

tₙ = -k²-k+1 + 2nk - 2k

tₙ = -k² + (2n-3)k + 1

Therefore, the nth term of the sequence is -k² + (2n-3)k + 1.

Answer:

To solve the polynomial (g^2 + 9g + 18 = 0) using the X or Box method, you need to factor the polynomial into two binomials. To do this, you need to find two numbers that multiply to 18 and add up to 9. The two numbers are 6 and 3, so the polynomial can be factored as:

g^2 + 9g + 18 = (g + 6)(g + 3) = 0

To find the solutions, you set each factor equal to 0 and solve for g:

g + 6 = 0, so g = -6

g + 3 = 0, so g = -3

The solutions to the polynomial are g = -6 and g = -3.

Answer:

I. 11%
II. ₹ 1110 in interest over 3 years

Step-by-step explanation:

To solve for the interest rate and the total interest earned, we can use the formula for compound interest:

A = P * (1 + r/n)^(nt)

where A is the maturity amount, P is the principal, r is the interest rate, n is the number of times compounded per year, t is the time in years, and

Since we know the maturity amount (A = ₹ 10,110), the principal (P = 250 * 12 * 3 = 9,000), and the time (t = 3 years), we can rearrange the formula to solve for the interest rate:

r = n * ((A/P)^(1/nt) - 1)

We'll assume that the interest is compounded monthly, so n = 12. Then:

r = 12 * ((10110/9000)^(1/36) - 1)

r ≈ 0.11

So, the interest rate is approximately 11% per year.

To find the total interest earned, we can use the formula:

Interest = A - P

Interest = 10110 - 9000

Interest = 1110

So, Mr Sharma earned ₹ 1110 in interest over 3 years.

The intensity of the transmitted light, [tex]I_{t}[/tex], is equal to half of the original intensity, [tex]I_{0}[/tex].

Given θ = 45° and cosθ = [tex]\sqrt\frac{I_{t} }{I_{0} }[/tex]

When polarized light with intensity [tex]I_{0}[/tex] strikes a polarized filter with its axis at an angle θ with the vertical, the intensity of the transmitted light, [tex]I_{t}[/tex], depends on the angle θ and the original intensity [tex]I_{0}[/tex]. The relationship between [tex]I_{t}[/tex] and [tex]I_{0}[/tex] is described by the equation cosθ = [tex]\sqrt\frac{I_{t} }{I_{0} }[/tex].

If θ = 45°, then the equation θ can be simplified to cos 45° =[tex]\sqrt\frac{I_{t} }{I_{0} }[/tex].

The cosine of 45° is equal to [tex]\frac{1}{\sqrt{2} }[/tex], so we have:

[tex]\frac{1}{\sqrt{2} }=\sqrt\frac{I_{t} }{I_{0} }[/tex]

On Squaring both sides, we have:

[tex]\frac{1}{{2} }=\frac{I_{t} }{I_{0} }[/tex]

Multiplying both sides by [tex]I_{0}[/tex], we have:

[tex]I_{t}=\frac{I_{0} }{2}[/tex]

Therefore, if θ = 45°, the intensity of the transmitted light, [tex]I_{t}[/tex], is equal to half of the original intensity, [tex]I_{0}[/tex].

The mean for boxplot #3 should be less than its median. In a negatively skewed distribution, the mean is less than the median.

This is because the few small values in the data pull the mean down, while the median is still at the middle value. A boxplot can give us an idea of the shape of the distribution, and if it is negatively skewed, it suggests that the mean will be less than the median.

It's important to note that without actually seeing the boxplot, this conclusion may not be accurate. There could be other factors that affect the mean and median, such as outliers or the size of the sample.

Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

Given that, a wall is 8 ft high and 16 ft long, having a window, mirror and a fireplace, with dimensions, 18 in(1.5 ft) by 14 ft, 5 ft by 3 ft and 4 ft by 2 ft respectively,

a) The area of wallpaper needed to cover the wall =

The area of wallpaper = area of wall - (sum of areas of the  window, mirror and the fireplace)

= 8x16-(14x1.5+5x3+4x2)

= 128-(21+15+8)

= 84 ft²

Therefore, the area of wallpaper needed to cover the wall is 84 ft²

b) (i) The area of one roll =

The dimensions of the roll are 1.5 ft by 33 ft, area = 49.5 ft²

(ii) The number of the roll required to cover the wall = 84 ft² / 49.5 ft²

Therefore, the number of the roll required to cover the wall is 2 rolls.

c) The cost of the rolls needed to cover the wall = 2 x 11.99 = $23.98

d) A gallon of the paint can cover 200 ft², costing $22.99/gallon,

1 ft² = 1/200 gallons

Therefore,

168 ft² = 168 x 1/200 = 0.84 gallons

Cost = 0.84 x $22.99

The fraction of the area of the triangle that would be shaded in stage 7 is equal to 2,187/16,384.

No, there isn't a stage when the fraction of area shaded would be equal to 0.

In Mathematics, a fraction simply refers to a numerical quantity which is not expressed as a whole number. This ultimately implies that, a fraction is simply a part of a whole number.

Next, we would determine the area of the triangle that would be shaded in stage 2 is as follows;

Fraction of the area = 3/4 × 3/4 = 9/16.

The area of the triangle that would be shaded in stage 3 is as follows;

Fraction of the area = 3/4 × 3/4 × 3/4 = 27/64.

The area of the triangle that would be shaded in stage 4 is as follows;

Fraction of the area = 3/4 × 3/4 × 3/4 × 3/4 = 81/256.

Therefore, the area of the triangle that would be shaded in stage 7 is as follows;

Fraction of the area = 3/4 × 3/4 × 3/4 × 3/4 × 3/4 × 3/4 × 3/4 = 2,187/16,384.

In this context, we can reasonably infer and logically deduce that there isn't a stage when the fraction of area shaded in this triangle would be equal to zero (0) because there is a linear relationship between the shaded and unshaded area.
