Answer:

A = 2200x - 2x^2

Step-by-step explanation:

Let's x be the length of the side that is NOT the same as the side along the river (or in opposite). From the fencing perimeter of 2200ft we can calculate the other side y of the rectangular:

y = 2200 - 2x

The area A of the pen would be the product of the 2 sides

A = xy = x(2200 - 2x) = 2200x - 2x^2

After t years the annual sales in hundreds of thousands of units of a product q is given by the equation q= (1/2)0.8t after how
Allushta [10]

Answer:

238375 years

Step-by-step explanation:

The equation for annual sales of product q is given as :

Annual sales of product q = (1/2)0.8t

Where t is time in years

We were asked to find in how many years that the annual sales would be 95350.

So we have,

95350 = (1/2)0.8t

95350 = 0.4t

Divide both sides by 0.4

We would have:

t = 95350 ÷ 0.4

t = 238375 years.

Therefore, the number of years after which the annual sales would be 95350 is 238375 years.

Please help me with this
m_a_m_a [10]

Explanation:

Steve correctly computed the change in x to be 2, and the change in y to be 6. However he put 2 in the slope formula for Δy (the change in y), and 6 for Δx. That is, Steve reversed the values of Δx and Δy.

The actual slope is ...

  slope = Δy/Δx = 6/2 = 3
