Afarmer is monitoring the water content of the soil during a dry summer. the water content of the soil is decreasing at a rate of 2.5% per

week. if a certain soil sample contains 200 grams of water on july 1st, which equation describes the relationship between y, amount of

water in grams, and t, time in weeks after july 1st?

• a. y=200(0.75)'

b. y=200(0.975)

•

c. y=200 - 0.025

d. y = 200 - 0.25t

Step-by-step explanation:

The general exponential growth or decay function is

           .... (1)

where, a is initial value, r is rate of change and t is time.

From the given information it is clear that

Initial water content of the soil = 200 grams

The water content of the soil is decreasing at a rate of 2.5% per.

Rate of change = -0.025

Substitute these values in equation (1).

Therefore, the required equation is .

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
