Rob has (1/2) * x - $25.75 of his earnings left from this week. This is obtained by subtracting the amount spent on bills and the cost of the video game from his total earnings.

To find out how much of his earnings Rob has left, we need to calculate the portion he spent and subtract it from his total earnings.

Given that Rob spends 1/2 of his earnings on bills, he has 1 - 1/2 = 1/2 of his earnings remaining.

If Rob buys a video game for $25.75, we can subtract this amount from his remaining earnings.

Let's say Rob's total earnings for the week were x dollars.

Amount spent on bills: (1/2) * x

Amount spent on the video game: $25.75

Remaining earnings: x - [(1/2) * x + $25.75]

Simplifying the expression, we have:

Remaining earnings: x - (1/2) * x - $25.75

Remaining earnings: (1/2) * x - $25.75

So, Rob has (1/2) * x - $25.75 of his earnings left from this week.

We have,

The function is,

W(x) = 145(1.05)ˣ represents the weight she is lifting after completing x training cycles.

In this case, x is 5,

so we substitute the value into the function.

W(5) = 145 (1.05)ˣ

       = 145(1.27628)

       = 170.93 pounds.    

The function W(x) = 145(1.05) is an exponential growth function, where the weight being lifted increases over time.

The base of the exponential function, 1.05, represents the rate of growth.

In this case, the rate of growth is,

1.05 - 1 = 0.05 or 5%

Each time the weight lifter completes a training cycle, the weight she is lifting is multiplied by 1.05.

Hence, After 5 training cycles, the weight lifter has multiplied the initial weight of 145 pounds by 1.05 five times,

= 145 x 1.05

= 170.93 pounds.

So, This demonstrates the compounding effect of exponential growth, where the weight being lifted gradually increases with each training cycle.

Therefore, after completing 5 training cycles, the weight lifter will be able to bench-press approximately 170.93 pounds.

After 10 seconds, the snail is 14 inches away from Diana. Let's assume that Diana is at the origin (0,0) and the snail moves at a constant speed. Let's consider the snail is at point (x, y) and Diana is at the origin (0,0). The snail is moving away from Diana at a constant speed. It moves 2 inches in 4 seconds.

Then the distance traveled by the snail in 1 second is

= 2/4inches

= 0.5 inches.

So, the distance the snail travels from (0,0) in x seconds is 0.5x. After 3 seconds, the snail moves

= 0.5(3)

= 1.5 inches away from Diana, and its distance from her is 9 inches.

So, we have y = 9 + 0.5x. This is the equation for the snail's distance from Diana, y, as a function of time, x.

We can see that the equation y = 9 + 0.5x provides the snail's distance from Diana. Here, y is the distance between Diana and the snail and x is the current time. We can observe that the snail moves at a constant pace of 0.5 inches per second since the coefficient of x is equal to 0.5. The constant term in the equation is 9, which stands for the separation between Diana and the snail at the initial value of x, or 0, the starting point.

Therefore, we can infer that the distance between the snail and Diana, y, as a function of time, x, is represented by the equation y = 9 + 0.5x. The distance between Diana and the snail can be calculated at any time using this equation. The distance between Diana and the snail after 10 seconds, for instance, can be calculated using this equation.

For this,

we substitute x = 10 in the equation and get

y = 9 + 0.5(10)

= 14.

Therefore, after 10 seconds, the snail is 14 inches away from Diana.

The number of white daffodils 39.6. To determine the number of white daffodils that go with 99 yellow daffodils using addition, we need the ratio between white daffodils and yellow daffodils.

Without the specific ratio, we cannot calculate the exact number. However, if we have the ratio, we can proceed as follows:

Let's assume the ratio of white daffodils to yellow daffodils is 2:5 (2 white daffodils for every 5 yellow daffodils).

To find the number of white daffodils, we can set up a proportion:

2 white daffodils / 5 yellow daffodils = x white daffodils / 99 yellow daffodils

Now, cross-multiply:

(2 white daffodils) * (99 yellow daffodils) = (5 yellow daffodils) * (x white daffodils)

198 white daffodils = 5x

To isolate x (the number of white daffodils), divide both side by 5:

198 white daffodils / 5 = x

x = 39.6 white daffodils

Since we cannot have a fraction of a daffodil, we would round the result. In this case, it would depend on the context or any specific instructions given.
