Machine A and machine B both make car parts.
Machine A makes 7 parts every 10 minutes.
Machine B makes 16 parts every 15 minutes.
On Monday
machine A makes parts for 12 hours
machine B makes parts for 10 hours
Work out the total number of parts made by the two machines on Monday.

Answers

Answer: 1144

Step-by-step explanation:

Given: Machine A makes 7 parts every 10 minutes.

i.e. it makes [tex]\dfrac{7}{10}[/tex] parts in 1 minute.

Machine B makes 16 parts every 15 minutes.

i.e. it makes [tex]\dfrac{16}{15}[/tex] parts in 1 minute.

On Monday,

machine A makes parts for 12 hours(720 minutes). [1 hour = 60 minutes, 12 hours = 12 x 6 = 720 minutes]

i.e. Total parts made = [tex]\dfrac{7}{10}\times720[/tex]

i.e. Total parts made = 504

machine B makes parts for 10 hours(=60x 10=600 minutes)

i.e. Total parts made = [tex]\dfrac{16}{15}\times600[/tex]

i.e. Total parts made = 640

Total parts made by both machines = 504+640 =1144

Hence, the total number of parts made by the two machines on Monday=1144.

The quadratic function f(x) has a vertex at (5,-5) and opens downward.

If g(x) = (x + 5)2 + 5, which statement is true?

A. The axis of symmetry of f(x) is x = 5, and the axis of symmetry of g(x) is x = -5.

B. The axis of symmetry of f(x) is x = -5, and the axis of symmetry of g(x) is x = -5.

C. The axis of symmetry of f(x) is x = 5, and the axis of symmetry of g(x) is x = 5.

D. The axis of symmetry of f(x) is x = -5, and the axis of symmetry of g(x) is x = 5.

Answers

Answer:

The correct answer is A.

Step-by-step explanation:

We're told that f(x) has its vertex at 5, -5 and opens downward. This tells us that it's axis of symmetry is x = 5.

The format of the function g(x) shows us that its axis of symmetry is x = -5. We're shown this because of the (x + 5)² component.

So the correct answer is A.

Using the properties of the quadratic function we can review the different answers, the correct one is

D. The axis of symmetry of f(x) is x = -5,

the axis of symmetry of g(x) is g(x) = 5.

The quadratic function is a quadratic polynomial that has a parabolic form and a general equation

g (x) = a x² + bx + c

where a, b, c are the coefficients, x is the independent variable and g the dependent

If the function has real roots it can be written in vertex form

g (x) = a (x-h) ² + k

where (h, k) are the coordinates of the vertex

The quadratic function has several properties:

The graph of this function opens up if the coefficient "a" is positive and down if it is negative, The axis of symmetry is parallel to the y axis, passing through the vertex of the function The vertex of the parabola corresponds to the maximum or minimum of the curve

The function can be written as a vertex value that cancels the binomial is where the symmetry axis passes

in this case, for the parabola to open downwards, the curve must be:

g (x) = - (x + 5) ² + 5

this is the expression in vertex form, let's find the value that cancels the binomial,

x + 5 = 0

x = -5

at this point where the axis of symmetry passes

The value of the function for this point is

x = -5

g (x0 = - (-5 + 5) ² + 5

g (x) = 5

Using the properties of the quadratic function we can review the different answers, the correct one is

D. The axis of symmetry of f(x) is x = -5, and the axis of symmetry of g(x) is

g(x) = 5

Using Delta y over Delta x, we are able to obtain m as -3/2

Next,

The following is the point-slope formula:

y-y₁=m(x-x₁)

Based on the graph, (4,-5) can be spotted as a definite ordered pair

Therefore, y-4= -3/2(x+5) fits the graph best and has the appropriate m value.

Write an equation that represents the situation then solve. (Explain/Justify your thinking.)

Answers

Answer:

Adventureland.

Coaster City

5 People

Step-by-step explanation:

The cost of Adventureland for p people is:

[tex]A=20+9p[/tex]

And the cost of Coaster City for p people is:

[tex]C=40+5p[/tex]

Part A)

If four people is going on the trip, p = 4. So, the cost for Adventureland is:

[tex]20 + 9(4) = \$ 56[/tex]

And the cost for Coaster City is:

[tex]40+5(4)=\$60[/tex]

Since $56 < $60, Adventureland will be a better option.

Part B)

If three extra people were invited, the total amount of people p is now 7. So, the cost to Adventureland is:

[tex]20 + 9(7) = \$ 83[/tex]

And the cost to Coaster City is:

[tex]40+5(7)=\$ 75[/tex]

Since $75 < $83, Coaster City is the better option in this case.

Part C)

So, we can set the two cost equations equal to each other:

[tex]20+9p=40+5p[/tex]

Solve for p. Subtracting 20 from both sides yields:

[tex]9p=20+5p[/tex]

And subtracting 5p from both sides yields:

[tex]4p=20[/tex]

And dividing both sides by 4:

[tex]p=5[/tex]

So, if 5 people went on a trip, the cost of going to either Adventureland or Coaster City will be the same.

Where was his tea, he wondered? He looked around to see whether the servants were arriving with the longed-for cup of steaming liquid. Dipping his fingers languidly into the cool pond, he delicately plucked out an oval-shaped purple leaf with fine-toothed edges, then let it drop so he could capture a newer one, a larger, brilliantly red leaf whose crinkled surface curled like the palm of a hand. Behind him, at the edge of the wide, sloping lawn, the tall, green fronds of bamboo waved, as mild as grazing sheep, and the politely clicking melody of wooden wind chimes wafted from the weathered pine balcony of his twelve-bedroom cottage. He would write a poem, he decided, for the leaf-watching festival, the Emperors favorite week of the year. A poem, perhaps about the bare slopes of Mount Atu, and a lone climber struggling up the mountainside as a late spring snow began to cover his shoulders. I am that climber, he thought, remembering the recent power struggles at the palace.All the nobles and royals of the court would be present at the poetry reading contest, returning from their summer retreats to begin the excitement of the new social season. Cranes would fly picturesquely across the face of the full moon; toy paper boats carrying small-flamed candles would drift like glad-eyed children on the palaces artificial lake. Sighing with expectation, the prince inhaled deeply the thin, tickling tang of pine-needle incense. Yes, the Emperor would approve of his poem, and perhaps grant him an honor such as the green sash of the Keeper of the Park! Our civilization, the prince thought, has reached a glorious peak.How does this passage convey a sense of the time during which the scene occurs?It specifies that the poem will be about a late spring snow.It mentions a full moon, cranes, and toy boats floating on a stream.It shows the prince's thoughts about certain events.It describes objects in nature that indicate the season. ***98 POINTS *** someone please help Dario is finding the percent of change from the original price of $75 to new price of $125. what is the range of possible sizes for x?
