Answer:

y = 5/2x - 11

Step-by-step explanation:

y = 5/2x + b

9 = 5/2 (8) + b

9 = 20 + b

-11 = b

y = 5/2x - 11

The height of the tree is closest to 40 feet.

We can use the proportion of similar triangles to determine the height of the tree.

Let h be the height of the tree and s be the length of the shadow cast by the tree.

We know that the height of the building is 60 feet and the length of its shadow is 21.5 feet. So:

(h/s) = (60/21.5)

We also know that the length of the shadow cast by the tree is 18 feet.

So we can substitute that into the proportion and solve for h:

h = (60/21.5) * 18

h = (60*18)/21.5

h ≈ 40

The angle of elevation of the ramp is 28.6 degrees.

Tan = (Change in Height) / (Length of Ramp)

Therefore, using the given information, the angle of elevation of the 23-foot ramp is:

Tan = (6 feet) / (23 feet)

Tan = 0.26

= 14.5° (to the nearest tenth of a degree)

Therefore, the angle of elevation of the 23-foot ramp is 14.5°.

Answer:

we have :

(a+b+c)² = a² + b² + c² + 2(ab+bc+ca)

a+b+c= 9

and

ab+bc+ca = 26

Substituting the values in the above formula,

We get,

9² = a² + b² + c² + 2×26

81 = (a² +b² +c²) + 52

(a² +b²+c²) = 81-52

(a²+ b² + c²) = 29 is a required answer.

A closed quadrilateral has four sides, four vertices, and four angles. It is a form of polygon. In order to create it, four non-collinear points are joined. Quadrilaterals always have a total internal angle of 360 degrees.

The Latin words quadra, which means four, and latus, which means sides, are combined to form the English word quadrilateral. A quadrilateral does not always have to have equal lengths on each of its four sides.

Given figure shows

GH parallel to EG

GH = EG

GH = 3y - 19

EG = 8

3y - 19 = 8

3y = 27

y = 9

GH = 3y - 19 = 3(9) - 19 = 8

and GJ parallel  to JE

GJ = JE

GJ = 3x + 1

JE = 5x - 3

3x + 1 = 5x - 3

5x - 3x = 1 + 3

2x = 4

x = 2

values are,

GJ = 3x + 1 = 3(2) + 1 = 7

JE = 5x - 3 = 5(2) - 3 = 7

FE = 6x - y

substitute values,

x = 2, y = 9

FE = 6x - y = 6(2) - 9 = 12 - 9 = 3

Hence x = 2, y = 9

GH = 8, GJ = 7,

So the only boundary point of [0,∞) and (0,∞) is 0 itself. It is in [0,∞), so that set is closed. It is not in (0,∞), so that set is open.

In mathematics, a (real) interval is a set of real numbers that contains all real numbers lying between any two numbers of the set. For example, the set of numbers x satisfying 0 ≤ x ≤ 1 is an interval which contains 0, 1, and all numbers in between. Other examples of intervals are the set of numbers such that 0 < x < 1, the set of all real numbers

the set of nonnegative real numbers, the set of positive real numbers, the empty set, and any singleton (set of one element).

Real intervals play an important role in the theory of integration, because they are the simplest sets whose "length" (or "measure" or "size") is easy to define. The concept of measure can then be extended to more complicated sets of real numbers, leading to the Borel measure and eventually to the Lebesgue measure.

Intervals are central to interval arithmetic, a general numerical computing technique that automatically provides guaranteed enclosures for arbitrary formulas, even in the presence of uncertainties, mathematical approximations, and arithmetic roundoff.

So the only boundary point of [0,∞) and (0,∞) is 0 itself. It is in [0,∞), so that set is closed. It is not in (0,∞), so that set is open.

The two companies will be equal in cost when 21.428 miles are driven.

How do you calculate the cost of rent?

The weekly rental amount is divided by 7 to determine the daily rental rate, then multiplied by 365 (days per year) to determine the yearly rate, and finally divided by 12 to determine the monthly rental amount. For example, a property is advertised as $200 per week, ($200 divided by 7) is $28.57 for the daily rate.

We can set up an equation to represent the cost of renting a car from each company in terms of the number of miles driven, and then solve for the number of miles at which the cost is the same for both companies.

Let x be the number of miles driven.

The cost of renting from Sunshine Rental Company is given by:

Cost1 = 17 + 0.5x

The cost of renting from Rent Me company is given by:

Cost2 = 20 + 0.36x

We can set the two equations equal to each other, and solve for x:

17 + 0.5x = 20 + 0.36x

0.14x = 3

x = 21.428 miles

Hence, the two companies will be equal in cost when 21.428 miles are driven.

Answer:

Volume of smallest container = 3141.6 cm³

Volume of middle sized container = 6283.2 cm³

Volume of largest container = 9424.8 cm³

Step-by-step explanation:

The formula to find the volume of a cylinder = πr²h

The height of each cylinder in a set of food-storage containers is 30 cm.

The radius of the largest container is 10 cm.

Step 1

We can find the volume of the largest cylinder

= r = 10cm

h = 30cm

Volume of largest cylinder = π × 10² × 30

= 9424.8 cm³

Step 2

We find the volume of the smallest container

We are told in the question:

The volume of the smallest container is one-third the volume of the largest container.

Hence

Volume of Smallest container = 1/3 (9424.8 cm³)

= 3141.6 cm³

Step 3

The volume of the middle-sized container is two-thirds the volume of the largest container.

Hence,

Volume of the middle sized container =

2/3 (9424.8 cm³)

= 6283.2 cm³

Therefore, the volume of each container is

Volume of smallest container = 3141.6 cm³

Volume of middle sized container = 6283.2 cm³

Volume of largest container = 9424.8 cm³
