What is the approximate area of the shaded sector in the circle shown below?

Answer:

Step-by-step explanation:

Assuming that the Skateboard is $180, and you are asking for the price when it is 30% off.

180 * .70 = $126

Another way of solving the question is finding 10 % of 180, which is 18. And you are looking for 30% less, so 18 * 3 = 54, which is 30% of 180.

180 - 54 = 126

The exact measurement could be between 2.7585 and 2.7595 cm.

The absolute error of a measurement is equal to one half the unit of measure. Absolute error is a measure of the difference between the actual value and the estimated or predicted value of a quantity. It is calculated by taking the absolute value of the difference between the actual value (often denoted as A) and the estimated or predicted value (often denoted as P).

Mathematically, the absolute error (AE) can be expressed as:

AE = |A - P|

The measurement is given to the nearest 0.001 cm.

So, the absolute error of the measurement is

\(${\frac{1}{2}}{\big(}0.001{\big)}=0.0005{\mathrm{~cm}}$\)

The exact measurement could be 2.759 ± 0.0005 or

between 2.7585 cm and 2.7595 cm.

0.0005 cm; The exact measurement could be between 2.7585 and 2.7595 cm.

Farmer Ed has 3,000 meters of fencing and wants to enclose a rectangular plot that borders on a river.The largest area that can be enclosed is 750,000 square meters.

To get the largest area that can be enclosed, we have to find the dimensions of the rectangular plot. Let's assume that the width of the rectangle is x meters.The length of the rectangle can be found by subtracting the width from the total length of fencing available:L = 3000 - x. The area of the rectangle can be found by multiplying the length and width:Area = L × W = (3000 - x) × x = 3000x - x²To find the maximum value of the area, we can differentiate the area equation with respect to x and set it equal to zero.

Then we can solve for x: dA/dx = 3000 - 2x = 0x = 1500. This means that the width of the rectangle is 1500 meters and the length is 3000 - 1500 = 1500 meters.The area of the rectangle is therefore: Area = L × W = (3000 - 1500) × 1500 = 750,000 square meters. So the largest area that can be enclosed is 750,000 square meters.

The equation for the forested area for t years after 1990 is  

y =  34400 \((0.983)^t\).

What is exponential decay?

The term "exponential decay" in mathematics refers to the process of a constant percentage rate reduction in an amount over time. It can be written as y=a(1-b)x, where x is the amount of time that has passed, an is the initial amount, b is the decay factor, and y is the final amount.

Here the initial forest area a = 34400 square kilometer.

Average rate = 1.7% = 1.7/100 = 0.017.

Now using exponential decay formula then,

=> y = a\((1-b)^t\)

Where t = number of years.

=> y = 34400(\(1-0.017)^t\)

=> y =  34400 \((0.983)^t\)

Hence the equation for the forested area for t years after 1990 is  

y =  34400 \((0.983)^t\).

a. Total depreciation = $9700

b. Depreciation per kilometer = $0. 388 per kilometer

c. Vₙ = $35400 +  ₙt

d. Distance = 4723. 16 kilometers

e. Total distance =  29723. 16 kilometers.

i. The formula for total depreciation is given as;

Total depreciation = Cost of asset - Residual value

Cost of car = $ 35400

Residual value = $25700

Total depreciation = $35400 - $25700

Total depreciation = $9700

b. Depreciation per kilometer = Total depreciation/ distance travelled in kilometers

Depreciation per kilometer = $ \(\frac{9700}{25000}\)

Depreciation per kilometer = $0. 388 per kilometer

c. Vₙ = V₀ + ₙt

t = time of depreciation

V₀ = $35400

Vₙ = $35400 +  ₙt

d. When the car costs $35400, it travelled 25000 kilometers

It costs $6688, it would travel 'x' kilometers

Cross multiply

$35400 × x = $ 6688 × 25000 kilometers

Make 'x' subject

x = \(\frac{6688 * 25000}{35400}\)

x = \(\frac{167200000}{35400}\)

x = \(4723. 16\) kilometers

The car would travel 4723. 16 kilometers

e. To find the total distance

Total distance = 25000 + 4723. 16

Total distance =  29723. 16 kilometers.

Answer:

y = \(\frac{1}{7}\) x + 30

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)

with (x₁, y₁ ) = (0, 30) and (x₂, y₂ ) = (70, 40) ← 2 points on the line

m = \(\frac{40-30}{70-0}\) = \(\frac{10}{70}\) = \(\frac{1}{7}\)

The line crosses the y- axis at (0, 30) ⇒ c = 30

y = \(\frac{1}{7}\) x + 30 ← equation of line
