As a result, the tunnel is 13.83 feet high, 5 feet from the edge.

An ellipse is an oval curve on a plane that contains two fixed points called foci. The sum of the distances between the two foci from each point on the ellipse is constant at all points.

Since the tunnel has an arch that is semi-elliptical, we can put the ellipse's center at the center of its 60-foot width.

What is an ellipse?

An ellipse is a two-dimensional shape that is defined by its axes in geometry. When a plane intersects a cone at an angle to its base, it creates an ellipse. It focuses on two things. For each point in the curve, the sum of the two distances to the focal point remains constant.

What are an ellipse and an example?

An ellipse is the locus of points whose sum of their distances from its two foci is constant and has an eccentricity of less than one. The two-dimensional egg shape and the running tracking in a sports stadium are simple examples of the ellipse in our everyday lives.

After 25 minutes will both aquariums contain the same amount of water.

Given:

Aquarium a contains 4. 6 gallons of water. Louise will begin filling aquarium a at a rate of 1. 2 gallons per minute. Aquarium b contains 54. 6 gallons of water. Isaac will begin draining aquarium b at a rate of 0. 8 gallon per minute.

Let y be the minutes

A(y) = 4.6 + 1.2y

B(x) = 54.6 - 0.8y

Same amount of water:

A(x) = B(x)

4.6 + 1.2y = 54.6 - 0.8y

1.2y + 0.8 y = 54.6 - 4.6

2y = 50

divide by 2 on both sides

2y/2 = 50/2

y = 25 minutes.

Therefore after 25 minutes will both aquariums contain the same amount of water.

The exponential form is  [tex]10^\frac{3}{2}= \sqrt{1000}[/tex].

Given expression is [tex](\sqrt{10})^3[/tex]

We know that

[tex](\sqrt{x})^n = x^\frac{n}{2}[/tex]

Therefore, [tex](\sqrt[]{10})^3 = 10^\frac{3}{2}[/tex]

Now, let's simplify the exponential form of this expression.

We know that [tex]a^\frac{m}{n} = nth root of a^m[/tex]

Therefore,

[tex]10^\frac{3}{2} =(\sqrt{10})^3[/tex]

[tex]10^\frac{3}{2}= \sqrt{1000}[/tex]

 Hence, the exponential form of the expression [tex](\sqrt{10})^3[/tex] is [tex]10^\frac{3}{2}= \sqrt{1000}[/tex] which simplifies to [tex]10^\frac{3}{2}[/tex].

The value of h(x) = -40x2 – 52x + 18. Option (b) is correct.

An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable is defined as a function.

Given functions

f(x) = -5x − 9

g(x) = 8x − 4

we have to determine which equation defines function h

f(x) = -5x − 9

g(x) = 8x – 4

(f x g) (x) = (-5x –9)(8x – 4)

(f x g) (x) = -40x2 + 20x – 72x + 36

(f x g) (x) = -40x2 – 52x + 18

Therefore the value of  h(x) = -40x2 – 52x + 18. Option (b) is correct.

Answer: 13 units

Step-by-step explanation:Given that Point C is the midpoint of AB and point B is between points A and D. If AD = 17 and BD = 9

According to definition midpoint, AC = CB

According to definition of segment addition postulate, AD = AB + BD

AB = AD - BD

AB = 17 - 9

AB = 8

Again, AB = AC + CB

Therefore, CB = AB/2

CB = 8/2 = 4

Now, CD = CB + BD = 4 + 9

CD = 13 units

Hence, length of CD = 13 units

The measures of the following angles are:

∠6 = 124°,  ∠2 =124°,  ∠3 = 124° ∠5 = 56°,  ∠7 = 124° ∠1 = 56°

Corresponding angles are the angles which are formed in matching corners or corresponding corners with the transversal when two parallel lines are intersected by any other line (i.e. the transversal).

∠4 = 56° ( corresponding angles are equal)

∠1 =∠4 ( vertically opposite angles are equal)

∠1 = 56°

∠7 + 56° = 180 ( angles on a straight line sum up to 180°)

∠7 = 180 - 56

∠7 = 124°

∠7 = ∠6 ( vertically opposite angle are equal)

∠6 = 124°

∠3 = ∠6 ( alternate angles are equal)

∠3 = 124°

∠2 = ∠3 ( vertically opposite angle)

∠2 = 124°

∠5 = 56° ( vertically opposite angles)

The unknown angles are: ∠1 = 56° ∠2 = 124°, ∠3 = 124°, ∠4 = 56°, ∠5 = 56°, ∠6 = 124° ∠7 = 124°

Answer:

Im guessing it would be a positive change

Step-by-step explanation:

part a had the cost of $100,000 while part b had the cost of $210,000

therefore, part b increased $110,000 from 2000 to 2008.

this is my guess.

The sum of two positive numbers is 120. The product of those numbers will be maximum if both numbers are equal to 60 and the maximum value is 3600.

Suppose we have a function f(x). At the extreme point (maximum/minimum), it holds:

      f ' (x) = 0

In the given problem, let the two numbers be a and b. Then,

a + b = 120 or

a = 120 - b   (equation 1)

f(b) = a x b = (120 - b) x b

f(b) = -b² + 120b

At the maximum point, the derivative with respect to b is zero,

f ' (b) = 0

-2b + 120 = 0

b = 120 / 2 = 60

Substitute b = 60 to equation 1,

a = 120 - 60 = 60

Hence, the two numbers that give maximal value of the product is 60 and 60. The product is 60 x 60 = 3600.

We can conclude that the maximum value of the product of those two numbers is 3600.

The vertices of the figure after geometric translations are (11, 5), (5, 4), and (9, 7).

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

It is given that:

The vertices are D(2,8), F(1,2) and G(4,6).

Points become after reflection:

D'(8, 2), F'(2, 1), G'(6, 4)

After applying translation:

D''(8+3, 2+3) = (11, 5)

F''(2+3, 1+3) = (5, 4)
