An arch in the shape of the upper half of an ellipse is used to support a bridge that is to span a river 20 meters wide. The hei

MatroZZZ [7]

Title:

<h2>Check the explanation.</h2>

Step-by-step explanation:

The standard form of an ellipse is $\frac{x^{2} }{a^{2} } + \frac{y^{2} }{b^{2} } = 1$ .

The span of the river is 20 meters. As per the given condition, y-axis will pass through the middle point of the river. That is why, the value of a will be $\frac{20}{2} = 10$ .

Since the height of the arc is 6, the value of b is 6.

The equation of the arc will become $\frac{x^2}{{10}^2} + \frac{y^2}{6^2} = 1$ .

Help please ASAP really need this

Dimas [21]

Answer:

Blue Line: y = 4x - 1

Green Line: y = -x + 6

Red Line: y = -x

Step-by-step explanation:

Looking at the equation y = mx + b

- The first giveaway is that the green line is the highest y-intercept (b- value). So we can say it's y = -x + 6

- Second giveaway is that the blue line has the lowest y-intercept (again the b- value). So we can say it's y = 4x - 1

- Third giveaway is that the red line has the same x-intercept AND y-intercept which is y = -x. Both intercepts are (0, 0).

Lastly, the rest of the statements are true in correspondence of the last 3 statements.

You bought a car for $50,000. Each year it depreciates in value by 7.5%.

sweet-ann [11.9K]

Answer:

y= 50,000(1-.075)^x

Step-by-step explanation:

The first year of depreciation is calculated by:

50,000 - (0.075)*(50,000) = 46,250

This can also be written as:

(50,000)*(1 - 0.075) [Pull out the 50,000]

The second year will depreciate starting with the $46,250 value at the end of the first year:

46,250 - (0.075)*(46,250) = 42,781

This may be written as:

(46,250)(1 - 0.075) = 42,781

The 46,250 was derived from the first year depreciation calculation, so we can substitute that instead of the 46,250:

((50,000)*(1 - 0.075))(1 - 0.075) = 42,781

This reduces to:

(50,000)*(1 - 0.075)^2 = 42,781. Note that the term (1-0.075) is now raised to the 2nd power. This power represents the 2nd year. Each succeeding year would be raised by one additional power, so that we can write a depreciated value after x years will be:

(50,000)*(1 - 0.075)^x
