Answer:

8+y\(\geq\)17

Step-by-step explanation:

Answer:

2sqrt(14)*i

Step-by-step explanation:

(sqrt(-56))

since theres a negative in it we know there will be an i in the answer.

We need to find two numbers that multiple to 56 with at least one of them being a perfect sqaure

7*8  doesn't work

4*14 = 56

ok sqrt(4) = 2

can't take the sqaure of (14)

so we are left with

2sqrt(14)*i <---remember from before?

The simplified expression where all the functions are of θ is cos^2θ - cos^4θ.

To simplify the expression (csc^2 θ - 1)/(1 + cot^2 θ), we can rewrite the trigonometric functions in terms of sine and cosine.

Using cscθ = 1/sinθ, cotθ = cosθ/sinθ these identities, we can rewrite the expression as follows:

(csc^2 θ - 1)/(1 + cot^2 θ)

= ((1/sinθ)^2 - 1)/(1 + (cosθ/sinθ)^2)

= (1/sin^2θ - 1)/(1 + cos^2θ/sin^2θ)

To simplify further, we can use the Pythagorean identity: sin^2θ + cos^2θ = 1.

Substituting sin^2θ = 1 - cos^2θ into the expression, we get:

(1/(1 - cos^2θ) - 1)/(1 + cos^2θ/(1 - cos^2θ))

= (1 - (1 - cos^2θ))/(1 + cos^2θ/(1 - cos^2θ))

= (cos^2θ)/(1 + cos^2θ/(1 - cos^2θ))

Simplifying the denominator:

1 + cos^2θ/(1 - cos^2θ) = (1(1 - cos^2θ) + cos^2θ)/(1 - cos^2θ)

= (1 - cos^2θ + cos^2θ)/(1 - cos^2θ)

= 1/(1 - cos^2θ)

Substituting this back into the expression, we have:

(cos^2θ)/(1/(1 - cos^2θ))

= cos^2θ * (1 - cos^2θ)

= cos^2θ - cos^4θ

Therefore, the simplified expression is cos^2θ - cos^4θ.

The rate at which the distance between the two cars is increasing two hours later is 52 mi/h.

To determine the rate of change of the distance between the cars, we can use the concept of relative velocity. Since one car is moving south and the other is moving west, their velocities are perpendicular to each other. Thus, we can use the Pythagorean theorem to find the distance between them at any given time.

After two hours, the southbound car would have traveled 48 mi/h * 2 h = 96 miles, and the westbound car would have traveled 20 mi/h * 2 h = 40 miles. Therefore, the distance between the cars is the hypotenuse of a right triangle with sides 96 miles and 40 miles.

Using the Pythagorean theorem, the distance between the cars is √(96^2 + 40^2) = √(9216 + 1600) = √10816 = 104 miles.

Since two hours have passed, the rate at which the distance is increasing is 104 miles / 2 hours = 52 mi/h. Therefore, the distance between the cars is increasing at a rate of 52 mi/h.

Answer: 127

Step-by-step explanation:

Therefore, the system of equations representing this situation is:

t + a = 110

0.40t + 1.20a = 80

To represent the given situation with a system of equations, we can set up the equations based on the information provided.

Let's use the variables t for the number of tetras and a for the number of angel fish.

The store sold a total of 110 fish over the weekend:

t + a = 110

The tetras sold for $0.40 each and the angel fish sold for $1.20 each, and the total revenue from selling those fish was $80:

0.40t + 1.20a = 80

Answer: 48 pupils get the bus to the cinema and 36 pupils walk to the cinema.

Step-by-step explanation:

Let's suppose that there are a total of N pupils.

We know that N/4 walk to the cinema.

We know that N/3 get the bus to the cinema.

And the remainder is equal to 60 people.

Then:

N - N/4 - N/3 = 60

N*(1 - 1/4 - 1/3) = 60

N( 12/12 - 3/12 - 4/12) = 60

N*( 5/12) = 60

N = (12/5)*60 = 144

Then the number of pupils that walk to the cinema is N/4, or:

144/4 = 36

And the number of pupils that get the bus is N/3, or:

144/3 = 48.

To find the rate of change of the function f(x) = x^2 - 8 at the numbers -7 and 7, we need to calculate the derivative of the function and evaluate it at those points. The rates of change, denoted as f'(-7) and f'(7), can be determined by finding the derivative of f(x) and substituting the respective values.

The derivative of f(x) = x^2 - 8 can be found by applying the power rule of differentiation. According to the power rule, the derivative of x^n is nx^(n-1).

Differentiating f(x), we get f'(x) = 2x.

To find the rate of change at -7, we substitute -7 into the derivative: f'(-7) = 2(-7) = -14. Therefore, the rate of change of f(x) at -7 is -14.

Similarly, substituting 7 into the derivative gives us f'(7) = 2(7) = 14. Thus, the rate of change of f(x) at 7 is 14.

In summary, the rate of change of f(x) = x^2 - 8 at -7 is -14, and at 7, it is 14.

SARSA alone cannot be used to estimate V(s). If we want to estimate the state values, we need to employ additional algorithms designed specifically for state-value estimation.

After applying the SARSA (State-Action-Reward-State-Action) algorithm, we can estimate the action-value function Q(s, a), which represents the expected return when taking action a in state s and following a specific policy. However, directly estimating the state-value function V(s) is not possible from SARSA alone.

The reason is that SARSA is an on-policy algorithm, meaning it estimates the value function for the policy it is following. It specifically focuses on learning action values rather than state values. As SARSA updates Q-values based on the actions taken and observed rewards, it does not directly estimate V(s).

To estimate the state-value function V(s), we typically use other algorithms such as Monte Carlo methods or TD (Temporal Difference) learning methods like TD(0) or TD(lambda). These algorithms directly estimate the state values without needing to estimate the action values.

Gross pay when she works 46 hours a week = 532 dollars per week

Step-by-step explanation:

Complete question

Find gross pay when she works 46 hours a week

Solution

For working hours less than or equal to 40 hours, kim earns 10.90  per hour

For working hours higher than the basic 40 hours of working, the per hour rate increases by 1.5 time = 1.5 *10.90 = 16 dollars per hour

Gross pay for 46 working hours = 40 *10.90 + 6*16 =  532 dollars per week

The height of the pile is increasing at a rate of approximately 0.056 feet per minute when the pile is 12 feet high.

We are given that sand is falling off at a rate of 14 cubic feet per minute, and the diameter of the base of the cone is approximately three times the altitude. Let h be the height of the pile at a given time t, then we can write the volume of the cone as V = (1/3)πr^2h, where r is the radius of the base of the cone. Since the diameter is three times the altitude, we have r = 3h/2.

Taking the derivative of the volume with respect to time, we get dV/dt = (1/3)π(9h^2/4)(dh/dt). Plugging in the given values, we get:

14 = (1/3)π(9h^2/4)(dh/dt)

Simplifying, we get:

dh/dt = 56/(3πh^2)

When the height of the pile is 12 feet, the rate of change of the height of the pile is:

dh/dt = 56/(3π(12)^2) ≈ 0.056 ft/min.

Therefore, the height of the pile is changing at a rate of approximately 0.056 ft/min when the pile is 12 feet high.
