Answer:

Tyler is correct. The temperature dropped at a rate of about 4° per hour between 4 and 6, while the temperature dropped at about 2.25° per hour between 6 and 10.

Edit: Explanation

The question is asking about which window of time had a faster decline in temperature, not a larger total change in temperature.

In a 2 hour timeframe, the temperature dropped 8°. (4-6 PM)

In a separate 4 hour timeframe, the temperature dropped 9°. (6-10 PM)

To find which window had a faster change in temp, I took the total temperature drop for each timeframe, then divided it by the number of hours each drop took.

8° / 2 = 4° per hour for 4-6 PM

9° / 4 = 2.25° per hour from 6-10 PM

Since the speed at which the temperature dropped per hour was greater from 4-6 PM than 6-10 PM, Tyler was correct.

Answer:

i agree with Mai because she/he (im not really sure) said that the temperature changed quicker in the time between 6 and 10 pm. the temperature change was 9 in those 4 hours.

Step-by-step explanation:

well there's a 4 hour difference between all 3 of the times

4 pm - 6pm

25 - 17 = 8

8 degree difference

6 pm - 10 pm

17 - 8 = 9

9 degree difference

the temperature changed quicker during 6 pm to 10 pm

2(y+2)-y=3(y-1)+9 I am solving for y​

Answers

Answer:

y = -1

Step-by-step explanation:

Step 1: Write equation

2(y + 2) - y = 3(y - 1) + 9

Step 2: Solve for y

Distribute: 2y + 4 - y = 3y - 3 + 9Combine like terms: y + 4 = 3y + 6Subtract y on both sides: 4 = 2y + 6Subtract 6 on both sides: -2 = 2yDivide both sides by 2: -1 = yRewrite: y = -1

Step 3: Check

Plug in y to verify it's a solution.

2(-1 + 2) - (-1) = 3(-1 - 1) + 9

2(1) + 1 = 3(-2) + 9

2 + 1 = -6 + 9

What is commutative property of addition?

The commutative property of addition says that it doesn't matter how we add two numbers, the result of the addition would be same.

For two numbers x and y, we have:

x + y = y + x

Suppose you've got 3 numbers as a, b, and c.

Then, we have

(a+b) + c = a + (b + c)

This property is called associative property.

Given;

3/4– 5+ 9 - 2/4 + 2

We can simpliyfying it by using the properties of addition ;

3/4– 5+ 9 - 2/4 + 2

(-5) + 9 + 2 + 3/4 + (-2/4)

Hence, the best use of the associative and commutative properties to

Answers

Answer:

Step-by-step explanation:

2. A computer shop charges P20.00 per hour (or a fraction of an hour) for the first
two hours and an additional P10.00 per hour for each succeeding hour. Find how
much you would pay if you will use one of their computers for: (a) 40 minutes (b) 3
hours (C) 150 minutes?​

Answers

Answer:

(a) For 40 minutes the charge is P20.00

(b) For 3 hours the charge is P30.00

(c) For 150 minutes the charge is P30.00

Step-by-step explanation:

The given parameters are;

The amount the computer shop charges for the first two hours = P20.00

The amount the computer shop charges for a fraction of an hour = P20.00

The amount the computer shop charges for each extra hour = P10.00

Therefore, the amount the computer shop will charge for each time, is given as follows;

(a) For 40 minutes, we have;

The duration of 40 minutes is less than two hours, therefore, the amount the computer shop will charge = P20.00

(b) For a duration of 3 hours, the amount the computer shop will charge is given by the following relation

The amount charged for the first two hours = P20.00

The amount charged for the next extra hour to make 3 hours = P10.00

The total amount charged for the 3 hours = P20.00 + P10.00 = P30.00

(c) For a duration of 150 minutes, we have;

150 minutes =  2 hours 30 minutes

Therefore, the amount charged will be equivalent to the amount charged for 3 hours or P20.00 + P10.00 = P30.00.

Charges per hour for the first 2 hours = P20.00Charges for each succeeding hour = Additional P10.00

The amount you would pay if you will use one of their computers for:

40 minutes

40 minutes is within the range of the first 2 hours. Therefore, you will pay P20.00 using their computers for 40 minutes.

3  hours

3 hours can be divided into: 2 hours + 1 hour

Charges per hour for the first 2 hours = P20.00

Charges for each succeeding hour = Additional P10.00

Hence:  2 hours + 1 hour

            P20.00 + P10.00

         = P30.00

Therefore, you will pay P30.00 using their computers for 3 hours.

150 minutes

Converting 150 minutes to hours

60 minutes = 1 hour

150 minutes = ?

150/60

= 2 .5 hours  = 2 hours 30 minutes

3 hours can be divided into: 2 hours + 1 hour

Charges per hour for the first 2 hours = P20.00

Charges for each succeeding hour = Additional P10.00

Therefore, you will pay

2 hours  + 30 minutes

P20.00 + P10.00

= P30.00

Therefore, you will pay P30.00 using their computers for 150 minutes.

What is Inequality?

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

For example, Olivia is selected in the 12U Softball. How old is Olivia? You don't know the age of Olivia, because it doesn't say "equals". But you do know her age should be less than or equal to 12, so it can be written as Olivia's Age ≤ 12. This is a practical scenario related to inequalities.

Show f(x)=x^3+e^x has exactly one real root?

Answers

Strategy: We need to do two things here. First, we show that the equation has a solution. Then we will need to show that there cannot be two solutions. We will use the Intermediate Value Theorem for the existence of a solution, and Rolle’s Theorem (or the MVT) for the fact that there is only one. Our strategy will include the idea that for the function f(x) = x3 + ex, this problem is equivalent to saying that the graph of f(x) has only one x-intercept.
Solution: First note that the function f (x) = x3 + ex is differentiable on all of R, since it is the sum of two differentiable functions, a polynomial and the exponential function. Hence it is continuous. Grabbingthetwoinputvaluesx=−1andx=0,weseethatf(−1)=(−1)3+e−1 =−1+1e <0, and f (0) = (0)3 + e0 = 1 > 0. Hence by the Intermediate Value Theorem, we know that there must be a number c ∈ [−1, 0], where f (c) = 0. But this is our solution to the original equation. Hence a solution exists.
So call c our solution to the original equation and suppose there exists another one; Call this one d. Then either d > c or d < c. It really won’t matter for our discussion, so assume d > c. Then f(x) is a continuous function on [c,d] and differentiable on (c,d) (it is differentiable everywhere, actually). By Rolle’s Theorem, there then must exist a point r ∈ (c,d), where f′(r) = 0. However, we have
f′(x) = 3x2 + ex > 0
for all x ∈ R. Thus, like our example in class, there cannot be a point r ∈ (c,d), where f′(r) = 0. So our assumption that there is a second solution to the original equation is incorrect. Thus there is only one real solution to x3 + ex = 0.
