Answer:

546

Step-by-step explanation:

The lateral area is made up of 4 faces that do not includes the bases.

2 faces have dimensions 2.5 ft by 21 ft.

2 faces have dimensions 10.5 ft by 21 ft.

LA = 2 * 2.5 ft * 21 ft + 2 * 10.5 ft * 21 ft

LA = 105 ft^2 + 441 ft^2

LA = 546 ft^2

Elenna [48]

Answer:

The slope of the line is 77

Explanation:

We know the speed is constant and that the mile-marker location over time can be represented by a line. This means that the equation is linear.

The slope can, therefore, be calculated as follows:

$slope = \frac{y_2-y_1}{x_2-x_1}$

where (x₁ , y₁) and (x₂ , y₂) are two points on the line

We are given that the two points (1, 123) and (3, 277) are two points in the line

Substitute with them in the above equation to get the slope as follows:

$slope = \frac{277-123}{3-2}=77$

Hope this helps :)

Log(1+y) - log(1-y) = log x in 2 decimal places, express y in terms of x

GaryK [48]

Answer: $y = \frac{x-1}{x+1}$

Step-by-step explanation:

$log(1+y) - log(1-y) = log x \\log\frac{1+y}{1-y} =log x\\x = \frac{1+y}{1-y}\\x(1-y)=1+y\\x-xy=1+y\\x-1 = xy+y\\y(x+1)=x-1\\y=\frac{x-1}{x+1}$
