3ay(a + 2y)^2
=3ay(a + 2y)(a + 2y)
=3ay (a^2 + 2ay + 2ay + 4y^2)
= 3ay (a^2 + 4ay + 4y^2)
= 3a^3y + 12a^2y^2 + 4y^3 a)

Yak Travel Agency arranges trips for climbing Mount Everest. For each trip, they charge an initial fee in addition to $0.15 for

Karo-lina-s [1.5K]

Answer: T = 120 + .15*x

Let T be the total price

Let 'I' be the initial price

Let 'x' be the total number of vertical meters

So, T = I + .15*x

Putting T = 645 and x = 3500 in above equation

we get, I = 120

So, the required equation is

T = 120 + .15*x

A bicycle race follows a triangular course. The 3 legs of the race are, in order, 2.3 km, 5.9 km, 6.2 km. Find the angle between

Bess [88]

Answer:

About 71.77 degrees

Step-by-step explanation:

The starting leg is 2.3 km and the finishing leg is 6.2 km.

Using the law of cosines C^2 = A^2 + B^2 -2AB*cos(c) where A = 2.3 km, B = 6.2 km, C = 5.9 km, and angle c is the opposite angle to side C, we get:

5.9^2 = 2.3^2 + 6.2^2 -2(2.3)(6.2)*cos(c)

cos(c) = -(5.9^2 - 2.3^2 - 6.2^2)/(2*2.3*6.2)

c = 71.77 degrees

A ballasted roof is flat and covered with gravel to hold the roofing material in place. Adam plans to cover the roof in the diag

Yuri [45]

Answer:

$Area = 2,031ft^2$

Total weight of gravel on the roof = $24,372 pounds$

Step-by-step Explanation:

The area Adams planned to cover with gravel can be divided into 3 rectangles as shown in the diagram attached.

We would have 3 rectangles. See the attachment below to check out how we arrive at the dimensions of the 3 rectangles.

Area of rectangle = L*W

Area to be covered by gravel = area of rectangle 1 + area of rectangle 2 + area of rectangle 3

Area to be covered with gravel = $(30*17) + (13*9) + (52*27)$

$Area = (30*17) + (13*9) + (52*27) = 2,031ft^2$

Total weight of gravel on the roof = 12 pounds per square foot multiplied by total area of the roof to be covered = $12 * 2031 = 24,372 pounds$
