Moving a figure around a fixed point in the plane is called making a ___.

The rocks are at the same height approximately 1.31 seconds after Noelle drops her rock and Cesar throws his, and at this time, they are both at a height of approximately 8.57 meters.

To determine the moment when Noelle's and Cesar's rocks are at the same height, we need to set the two functions equal to each other and solve for x. Noelle's rock has the height function f(x) = -4.9x² + 17 and Cesar's rock has the height function g(x) = -4.9x² + 13x.

We solve for x when f(x) = g(x):
-4.9x² + 17 = -4.9x² + 13x
This simplifies to:
17 = 13x
Solving for x gives us:
x = 17/13
x ≈ 1.31 seconds

At approximately 1.31 seconds after Noelle drops her rock and Cesar throws his, both rocks are at the same height. To find this height, we substitute x back into either f(x) or g(x). Using Noelle's function, we get:
f(1.31) = -4.9(1.31)² + 17 ≈ 8.57 meters

Therefore, both rocks are at a height of approximately 8.57 meters 1.31 seconds after their respective releases.

Bax invested a total of $2000 in two simple interest accounts. Account A earns 3% interest and Account B earns 5% interest. Bax earned a total of $75 interest after one year. How much did Bax invest in each account?

Let, The amount invested in Account A=x

Then, the amount invested in Account B=2000-x

The formula of Simple Interest =[tex] \frac{Principle*Rate*Time}{100} [/tex]

Interest earned in Account A in 1 year=[tex] \frac{x*3*1}{100} [/tex]

Interest earned by Account A=[tex] \frac{3x}{100} [/tex]

Interest earned in Account B in 1 year=[tex] \frac{(2000-x)*5*1}{100} [/tex]

Interest earned by Account B=[tex] \frac{5(2000-x)}{100} [/tex]

Total Interest Earned= Interest earned by Account A+ Interest earned by Account B

Total Interest Earned=[tex] \frac{3x}{100} [/tex]+[tex] \frac{5(2000-x)}{100} [/tex]

75=[tex] \frac{3x}{100} [/tex]+[tex] \frac{10000-5x)}{100} [/tex]

75=[tex] \frac{3x+10000-5x)}{100} [/tex]

Multiply by 100 on both sides

75*100=[tex] \frac{100(10000-2x))}{100} [/tex]

7500=10000-2x

Let us subtract 7500 from both sides

7500-7500=10000-7500-2x

0=2500-2x

Adding 2x on both sides, we get

0+2x=2500-2x+2x

2x=2500

To solve for x, divide by 2 on both sides

2x/2=2500/2

x=1250

So, The Amount invested in Account A= $1250

The Amount invested in Account B= $2000-1250=$750

Answer:

g(x) = (x - 8)² - 64 will be the answer.

Step-by-step explanation:

The given function in the standard form is g(x) = -16x + x²

We have to write this function in the vertex form.

Since vertex form of a quadratic function is in the form of

f(x) = (x - h)² + k

Therefore, g(x) = x² - 16x may be written as

g(x) = x² - 16x + 64 - 64

      = x² - 2(8x) + 64 - 64

      = (x - 8)² - 64

Therefore, g(x) = (x - 8)² - 64 will be the answer.

1. The Temple in Jerusalem was destroyed in the year of 70 AD.

The first Temple was built by King Solomon for seven years in the 10th century BC. The first Temple was destroyed by the Babylonians in 586 BC. The construction of the new Temple began 535 BC and it is completed in 516 BC. The rebuilding of the Temple was approved by Darius I. It was, however, destroyed by the Romans in 70 AD. Despite the fact that the Temple was destroyed, all the outer walls still stand, and for a long time, it was believed that only the west wall stood.

The provincial governors in Rome were given orders to openly persecute the Christians by Emperor Trajan.

This can be concluded from the letter sent to him by Pliny, governor of Bithynia (province of Asia Minor). He had doubts about the investigation and the way of punishing those who were accused as Christians because he never been present at any trials of Christians. This implies that there have already been trials for Christians and that he did not know the details about Trajan’s decree of prosecuting Christians.

The Roman emperor who passed a decree to require everyone to participate in the cult of emperor worship was Decius.

Emperor Decius (249-251) announced the edict that orders everyone to do sacrifice to the Roman gods and to him personally. According to the edict, the sacrifice had to be carried out in the presence of a Roman magistrate who issued a certificate that this had been done. There is no evidence that it was directed against the Christians, but it was fatal for them because was contrary to their beliefs.

1 Peter 3:17: "For it is better, if  God should will it so, that you suffer for doing what is right rather than for doing what is wrong."

The quote is from the First Epistle of Peter, which is part of the New Testament. It is written by Peter the Apostle in Rome (where he was a bishop) as the letter which is sent to believers in Asia Minor who were persecuted and tortured.

The most damaging charge brought against the Christians in Rome was that they were constant law-breakers who did not discharge their duties to the state.

The Roman authorities consider Christians as opponents of the state that promoted treasonous activities and they were apprehended for disobedience. Suspected Christians have often refused to deviate from Christianity in order to comply themselves with acts of a state cult, which was understood as a public cancellation of loyalty to the state.

We find that Grayson charges more than Ian when the number of hours of service h is less than 2.

To determine for how many hours Grayson charges more than Ian, we can set up an equation where the cost of Grayson's tax preparation service is greater than Ian's service. Grayson charges $35 per hour plus a $35 administration fee, while Ian charges $45 per hour plus a $15 administration fee. The number of hours for which the service is required is represented by h.

Grayson's total charge for h hours would be:

Grayson's Cost = $35h + $35

Ian's total charge for h hours would be:

Ian's Cost = $45h + $15

To find the number of hours where Grayson's cost is more than Ian's cost, we set Grayson's Cost > Ian's Cost:

$35h + $35 > $45h + $15

Simplifying, we get:

$35h - $45h > $15 - $35

-$10h > -$20

Dividing both sides by -10 (and remembering to reverse the inequality when dividing by a negative):

h < 2

Thus, Grayson charges more than Ian for fewer than 2 hours of tax preparation.

Step-by-step explanation:

We can find the solution directly on the graph. The solution of a system of equations is the intersections between the two lines. Remember that each equation in this case represent a line, where the common points are always shown as an intersection.

To prove this result, we can apply other methods. Using the substitution method, we have to isolate one variable from one equation and then replace it in the other equation, like this:

[tex]\left \{ {{y=-x+52'} \atop {y=2x-1}} \right.[/tex]

The variable y is already isolated, now we just replace the first equation in the second:

Final answer:

When a number in scientific notation is multiplied by 100, its exponent of 10 increases by 2 since 100 is equivalent to 10 squared (10²). For example, 3.14 x 10⁴ multiplied by 100 becomes 3.14 x 10⁶.

Explanation:

When you multiply a number in scientific notation by 100, the exponent of 10 increases by 2.

This is because 100 can be written as 10² or 10 squared.

So, if we have a number like 3.14 × 10⁴ and we multiply by 100, we are essentially multiplying by 10².

We keep the coefficient the same (3.14) and add the exponents of 10:

The resulting scientific notation is 3.14 × 10⁶, which means the exponent of 10 increased by 2 as we multiplied by 100.

Final answer:

Quick Fix Inc. breaks even after 7 hours of labor. This is determined by setting the revenue function equal to the overhead cost function and solving for the variable h (hours), which results in a quadratic equation that factors to reveal the break-even point.

Explanation:

To find out after how many hours Quick Fix Inc. breaks even, we need to set the company's revenue function equal to its overhead cost function. The revenue function is given by R(h) = 220h - 160 and the overhead cost function is given by C(h) = 20h2 - 400. The break-even point occurs when R(h) = C(h).

To solve for h (hours), we rearrange the equation: [tex]20h^2 - 220h + 160 + 400 = 0, or \\20h^2 - 220h + 560 = 0.[/tex]

Divide through by 20 to simplify: [tex]h^2 - 11h + 28 = 0.[/tex]

Factoring the quadratic equation gives us: (h - 7)(h - 4) = 0.

Set each factor equal to zero and solve for h: h - 7 = 0 or h - 4 = 0, thus h = 7 hours or h = 4 hours.

Since we are looking for a positive number of hours, we need to test which solution makes sense in the context of the problem. After examining both possibilities, we conclude that the company breaks even at 7 hours, because at 4 hours, the cost would still exceed the revenue.
