Mr Prothero places £3003 into a
savings account and gains 9%
interest per annum. How much
money is in the account after 2
year?

Answers

Answer:

£3,543.54

Step-by-step explanation:

Amount after 2 years = Principal + interest

Get the interest

Interest = PRT/100

Interest = 3003 * 9 * 2/100

Interest = 3003 * 18/100

Interest = 30.03 * 18

Interest = 540.54

Amount after 2 years = 3003 + 540.54

Amount after 2 years = £3,543.54

Which recursive rule best describes the sequence 3, 14, 36, 80, ...

Answers

Answer c -step explanation:

The recursive rule that best describes the sequence 3, 14, 36, 80, ...is [tex]a_{n} =2a_{n-1} +8[/tex].

What is a sequence?

A sequence is a particular order in which related things follow each other.

Let us cross-check the recursive rule [tex]a_{n} =2a_{n-1} +8[/tex]....(1)

Given sequence is: 3, 14, 36, 80, .....

Put n=1, 2, 3 in (1)

[tex]a_{2} =2a_1+8\\a_{2} =2*3+8\\a_{2} =14[/tex]

[tex]a_{3} =2a_2+8\\a_{3} =2*14+8\\a_{3} =36[/tex]

[tex]a_{4} =2a_3+8\\a_{4} =2*36+8\\a_{4} =80[/tex]

We are getting the sequence as 3, 14, 36, 80, ..... i.e. same as the given sequence.

Therefore, the recursive rule that best describes the sequence 3, 14, 36, 80, ...is [tex]a_{n} =2a_{n-1} +8[/tex].

Step-by-step explanation:

9514 1404 393

Answer:

translates the figure 7 units left and 8 units down

Step-by-step explanation:

You know that increases in x-coordinate move a point to the right. So, decreasing the x-coordinate by 7 units will move a point to the left by 7 units.

Likewise, increasing the y-coordinate will move a point up. So, decreasing the y-coordinate by 8 units moves the point down 8 units.

The transformation ...

(x, y) ⇒ (x -7, y -8)

translates the figure 7 units left and 8 units down.

Answers

Step-by-step explanation: Your equation isn't making complete sense to me. But since it sounds like x+5 is in the denominator, if I had to guess, I'd say when x = -5. This is when the denominator equals 0. Since we can't divide by 0, it's an asymptote.

What percentage is the discount? Write your answer using a percent sign (%). Write a short summary of this story.Shadrach, Meshach, and Abed-nego Proud King Nebuchadnezzar made an image of gold and set the huge idol in the plain of Dura in the province of Babylon. He called many important people to come and help him dedicate the image.When all had gathered before the image, the herald announced the royal decree. "It is commanded, O people, when you hear the music, you shall fall down and worship the golden image that King Nebuchadnezzar has set up, and whoever does not fall down to worship shall in the same hour be cast into a burning fiery furnace."The musicians began to play. When the people heard the music, they fell down in fear to worship the image.Soon it was discovered that certain Jews, whom the king had set in charge over the affairs of the province of Babylon, did not bow down and regard the king's wishes.The king ordered Shadrach, Meshach, and Abed-nego to explain their actions. "Is it true that you do neither serve my gods nor worship the golden image I have set up?" the king questioned with indignant anger. "Now be ready when you hear the music to bow down and worship the image I have made. However, if you do not, you shall be cast the same hour into a burning fiery furnace. Who do you think will save you from certain death?"Shadrach, Meshach, and Abed-nego courageously replied, "Our God is able to deliver us from the burning furnace, and He will deliver us out of your hand. If not, be it known to you, we will neither serve thy gods nor worship the golden image."Full of fury, Nebuchadnezzar commanded the furnace heated seven times hotter than before. He called his mightiest men to bind and cast the three men into the furnace. Because the king's command was so urgent and the furnace exceedingly hot, the flames killed the men who threw the men into the furnace.Astonished, the king suddenly rose up and said, "Did we not cast three bound men into the fire?""Yes, king," was the answer."Then why do I see four men loose, walking in the midst and they are not hurt? The fourth is like the Son of God."Nebuchadnezzar came closer to the furnace to speak to the men. "Shadrach, Meshach, and Abed-nego, servants of the most high God, come out!"As the three men came out of the fire, the people could all see that no harm had become them. The hair was not even singed, their coats were not scorched, nor did they smell of fire.Nebuchadnezzar humbly said, "Blessed be the God of Shadrach, Meshach, and Abed-nego, Who hath sent His angel and delivered His servants who trusted in Him. He had changed the king's word and yielded their bodies that they might not serve or worship any god, except their own God."He then made a new decree. "No one should speak against the God of Shadrach, Meshach, and Abed-nego. No other God can deliver us."Shadrach, Meshach, and Abed-nego were awarded a higher office in the province of Babylon.
