Which of the following expressions is
equivalent to the expression below?
3(2x + 4)
А 3х + 4
C 6x + 4
B 6x + 12

Answers

Answer:

6x + 12

Step-by-step explanation:

this is because 3 times 2x = 6x and 3 times 4 = 12.

Answer:

6x+12

Step-by-step explanation:

Let f(t) represent the temperature of a turkey baking in an oven as a function of time t in the oven (in minutes). This means time is the independent variable and temperature of the turkey is the dependent variable. The turkey was in the oven for 360 minutes and then removed. Note that when something is baked in an oven, the temperature of the oven stays constant.

Explain the meaning of each statement in the context of the situation using everyday language. Remember that the input of the function t is the time in the oven and the output f(t) is the temperature of the turkey at that time.

1. f(0) = 50. (8 points)

2. f(120) > f(60). (8 points)

3. f(360) = f(345). (7 points)

4. f(390) < f(360). (7 points)

Answers

Answer:

Step-by-step explanation:

1. f(0) = 50. (8 points) The beginning temperature of the turkey was 50 degrees. The '0' represents "beginning."

2. f(120) > f(60). (8 points) The temperature of the turkey after 120 min (2 hours) is greater than that after 60 minutes (1 hour).

3. f(360) = f(345). (7 points) The temperature of the turkey is the same after 360 minutes as it is after 345 minutes.

4. f(390) < f(360). (7 points)

The temperature of the turkey drops after 360 minutes (6 hours), because the turkey is taken out of the oven and/or the oven is turned off.

Answers

Answer:

y-int = (0, -1.26)
x-int = (2, 0)

Explanation:

Key: 3/ = cube root
| = end of cube root

To find the y-int, you make x equal to zero...

3/ x - 2
3/ 0 - 2
3/ -2

and to find the x-int, you make the entire function equal to zero...

3/ x - 2 | = 0
x - 2 = 0 (cube sides to get rid of cube root)
x = 2

To find any other points, just plug in an x to the original function, and the answer you get will be the y.

Hopefully this helped!

Una botella pesa 1090kg cuando esta llena y 250g cuando esta vacía. ¿Cuanta masa de aceite contiene la botella?

Answers

Respuesta:

1089,75 kg

Explicación paso a paso:

Dado que :

Masa de embotellado lleno = 1090 kg

Masa de la botella vacía = 250 g

Masa de aceite que contiene la botella:

Expresando la masa de la botella cuando se llena en gramos:

1000 g = 1 kg

1090 kg = (1090 * 1000) = 1090000 g

La masa de aceite que contiene la botella es así:

Masa de la botella cuando está llena - masa de la botella cuando está vacía

1090000 g - 250 g = 1089750 g

Por tanto, la masa de aceite es 1089750 g

O 1089750/1000 = 1089,75 kg

Solve the system by using the elimination method.

Answers

Answer:

(8, 4 )

Step-by-step explanation:

Given the 2 equations

5x - 5y = 20 → (1)

- 3x + 5y = - 4 → (2)

Add the 2 equations term by term to eliminate the y- term

2x + 0 = 16

2x = 16 ( divide both sides by 2 )

x = 8

Substitute x = 8 into either of the 2 equations and solve for y

Substituting into (2)

- 3(8) + 5y = - 4

- 24 + 5y = - 4 ( add 24 to both sides )

5y = 20 ( divide both sides by 5 )

y = 4

solution is (8, 4 )

On a given planet, the weight of an object varies directly with the mass of the object. Suppose that an object whose mass is 9 kg weighs 63 N . Calculate the mass of another object that weighs 14 N.

Answers

Answer:

The mass is 2 kg.

Step-by-step explanation:

W = kM where k is a constant so

63 = k*9

k = 7

So: W = 7M

when W = 14:

14 = 7M

M = 2.

Answers

Answer:

FHG is 45 degrees

Step-by-step explanation:

For a square, each of the angles at the corners measure 90 degrees

Also, the two diagonals are equal and they bisect one another

Also, the diagonals bisect each of the angles at the corners making each angle lying in each triangle to be 45 degrees, thereby creating 4 isosceles right triangles

For FHG, looking at the triangle FHG, FG and GH are equal lengths as we have an isosceles right triangle

An isosceles right triangle is only possible when the two internal angles asides the right triangle are 45 degrees each

What this mean is that FHG measure is 45 degrees

Read the passage.story adapted from The Odyssey, BOOK IXby HomerThe cave had looked like a promising place, awash with food and drink aplenty. It was empty, so Odysseus suggested that they wait for its owner to return, hoping for a hospitable inhabitant. The soldiers advised against this, but Odysseus insisted. Not long after, they discovered that their host was the quite inhospitable Cyclops, who proceeded to trap them in the cave by blocking the entrance with an enormous rock. Many of Odysseuss men had suggested ending the beasts life, but that would leave them trapped in the cave. Even if they all worked together, they would not have the strength to remove the boulder from the caves opening. For the past few days, Odysseus had observed the one-eyed monster. He had noticed that every morning, the Cyclops removed the rock from the caves opening to let out his flock of sheep before replacing it to keep Odysseus and his men confined inside. "We will blind the monster. Then, well use his own sheep to aid us in our escape, Odysseus explained to his crew. I have noticed that the males are fully grown and have thick black wool. We can tie three of them together. Then, we can hide a man under the belly of the middle animal. This way, hell be able to pass by the Cyclops unnoticed. Once the monster had fallen asleep, Odysseus blinded the Cyclops. The beast cried out in pain but then drifted back into slumber as the soldiers had shared their strong mead with him that night. Odysseus and the men worked all night to make sure there were three sheep for each man. Once his crew was hidden, Odysseus leapt onto the remaining sheepa ram that was finer than all the others. Then, he wiggled his way underneath the animal, concealing himself in the dark wool hanging below the rams belly. As dawn approached, the men were fearful that the plan would not succeed, but they knew they must carry on if they hoped to escape the Cyclopss lair. When the sun rose above the horizon, the Cyclops awoke and opened the cave entrance for his flock. Despite his pain, the Cyclops felt the back of each animal as it stood up and left the cave. He was not aware that the men were hidden beneath their bellies.As the last sheep went out, the fine ram concealing Odysseus, the Cyclops grabbed hold of the animal. My good ram, why are you last today? You never let the others go ahead of you, the Cyclops mused aloud. Youre usually the one leading the restwhether it is to go out and eat in the morning, or it is to come home at night. Odysseus held his breath; would they be discovered? But to his relief, the monster let the ram go out to the pasture with the other sheep. Finally, when they were far enough from the cave, Odysseus let go of the rams belly and helped his men to do the same. They drove the sheep to their awaiting ship, and once all men and animals were on board, the soldiers cried in relief at their narrow escape. Odysseus signaled for them to hush. He realized that they were still in range of the Cyclopss hearing. The men understood and quickly began to row the ship out to sea. But Odysseus could not resist taunting the Cyclops from the deck of the ship. Cyclops, Odysseus shouted, you did wrong by trapping us, and now the gods have punished you. The Cyclops grew furious. In his rage, he ripped off the top of a mountain and hurled it toward the sound of Odysseuss voice. The piece of the earth plunged into the water just in front of the ship. This caused a wave that carried the ship back toward the Cyclops's land. Odysseus picked up a long stick and quickly drove it into the sea to stop the motion of the ship. He nodded his head toward the men, indicating that they must row for their lives, which they did. Odysseus was so angry he could not resist insulting the Cyclops further. Monster, he yelled, if anyone asks you how you lost your sight, you can tell them that it was I, the valiant warrior Odysseus. The Cyclops grabbed a giant piece of land, even larger than the first, and threw it with all his might. This time, the wave it caused drove the ship toward the island, where the rest of the soldiers were anxiously awaiting Odysseuss return.In the story adapted from Book IX of The Odyssey, what does Odysseus's scheme involving the sheep reveal about him?A: He is an expert fighter.B: He is unnecessarily cruel.C: He is a cunning strategist.D: He is motivated by fear.
