Answers

Answer:

1. 11

2. 20

3. 34

4. 12.6

5. 18

6. 105

Step-by-step explanation:

We are told that ---> t = 0, x = 1.5, y = 6, and z = 23

1. y + 5

= 6 + 5

= 11

2. z - 2x

= 23 - 2(1.5)

= 23 - 3

= 20

3. 2z - 2y

= 2(23) - 2(6)

= 46 - 12

= 34

4. 2.6y - 2x

= 2.6(6) - 2(1.5)

= 15.6 - 3

= 12.6

5. 4(y - x)

= 4(6 -  1.5)

= 24 - 6

= 18

6. 4(2 + z) + 5

= 4(2 + 23) + 5

= 8 + 92 + 5

= 105

Measuring the speed of sound in the ocean is an important part of marine research. One application is the study of climate change. The speed of sound depends on the temperature, salinity, and depth below the surface. For a fixed temperature of 25 degrees Celsius and salinity of 35 parts per thousand, the speed of sound is a function of the depth. At the surface, the speed of sound is 1534 meters per second. For each increase in depth by 1 kilometer, the speed of sound increases by 17 meters per second.

What increase in the speed of sound is caused by a 4-kilometer increase in depth?

Answers

Step-by-step explanation:

speed of sound in x depth = 1534 + 17x

4 × 17 = 68 is the increase of sound speed caused by 4 km increase in depth

- 11 - 2p = 6р +5(p+3)
What would this be?

Answers

Answer:

[tex] - 11 - 2p = 6p + 5(p + 3) \\ - 11 - 2p = 6p + 5p + 15 \\ p \: termstogther \\ - 11 - 15 = 6p + 5p + 2p \\ - 26 = 13p \\ p = \frac{ - 26}{13} = -2 \: p = -2\\ thank \: you[/tex]

Answer: p = -2

Step-by-step explanation:

Given expression

-11 - 2p = 6p + 5(p + 3)

Expand parentheses and apply the distributive property

-11 - 2p = 6p + 5p + 15

Combine like terms

-11 - 2p = (6p + 5p) + 15

-11 - 2p = 11p + 15

Add 11 on both sides

-11 - 2p + 11 = 11p + 15 + 11

-2p = 11p + 26

Subtract 11p on both sides

-2p - 11p = 11p + 26 - 11p

-13p = 26

Divide -13 on both sides

-13p / -13 = 26 / -13

Examine whether each of the following pair of lines AB and CD are parallel or not​

Answers

Answer:

Yes

Step-by-step explanation:

For lines to be parallel alternate interior angles should be equal

Angle GHD=180-angle FHD

=180-115 = 65°

Therefore angle AGH = angle GHD

So lines are parallel

Step-by-step explanation:

[tex] \angle H = 115 \degree ... (vertical \: \angle s) \\ \angle H + 65 \degree \\ = 115 \degree + 65 \degree \\ = 180 \degree \\ [/tex]

Therefore by interior angle test,

g(x)=x^2-5
g(9)
help!

Answers

You’re given g(x) = x^2 - 5

When asked to find g(9), you’re being told that x=9, since the x in the g(x) was replaced by 9.

So that’s telling you to put 9 in for all x’s:
g(9) = (9)^2 - 5

You then just need to clear up the right hand side.

9^2 - 5 = 81 - 5

= 76

So, g(9) = 76

Multiply through by 6 ( the LCM of 2, 6, 3 ) to clear the fractions

3(x - 2) + x - 2(x - 4) = 2x ← distribute parenthesis on left side

3x - 6 + x - 2x + 8 = 2x

2x + 2 = 2x ( subtract 2 from both sides )

2x = 2x - 2 ( subtract 2x from both sides )

0 = - 2 ← not possible

This indicates the equation has no solution

The simple interest formula is I = Prt, where I represents simple interest on an amount, P, for t years at a rate of r, where r is expressed as a decimal What is the amount of money, P, that will generate $40 in interest at a 10% interest rate over 5 years?

Answers

Answer:

Using the simple interest formula

I = P r t

P = I /  (.10 * 5) = 2 I = 80 $      at a 10% rate / year

Note in 1 yr   I = 80 * .1 * 1 = 8 $   so 40$ will be generated in 5 yrs

If the money were reinvested

A = P (1 + i)^n = 80 ( 1.1)^5 = 128.84  giving 48.84 interest after 5 years

Answer:

Step-by-step explanation:

Answer:

80

Step-by-step explanation:

I = Prt

I = 40  R = .10  T = 5

40 = P (.10)(5)

40 = P(.5)

Divide each side by .5

40/.5 = .5P/.5

80 = P

Memories of a MemoryHave you ever witnessed something amazing, shocking or surprising and found when describing the event that your story seems to change the more you tell it? Have you ever experienced a time when you couldn't really describe something you saw in a way that others could understand? If so, you may understand why some experts think eyewitness testimony is unreliable as evidence in scientific inquiries and trials. New insights into human memory suggest human memories are really a mixture of many non-factual things.First, memory is vague. Imagine your room at home or a classroom you see every day. Most likely, you could describe the room very generally. You could name the color of the walls, the floors, the decorations. But the image you describe will never be as specific or detailed as if you were looking at the actual room. Memory tends to save a blurry image of what we have seen rather than specific details. So when a witness tries to identify someone, her brain may recall that the person was tall, but not be able to say how tall when faced with several tall people. There are lots of different kinds of "tall."Second, memory uses general knowledge to fill in gaps. Our brains reconstruct events and scenes when we remember something. To do this, our brains use other memories and other stories when there are gaps. For example, one day at a library you go to quite frequently, you witness an argument between a library patron and one of the librarians. Later, when telling a friend about the event, your brain may remember a familiar librarian behind the desk rather than the actual participant simply because it is recreating a familiar scene. In effect, your brain is combining memories to help you tell the story.Third, your memory changes over time. It also changes the more you retell the story. Documented cases have shown eyewitnesses adding detail to testimony that could not have been known at the time of the event. Research has also shown that the more a witness's account is told, the less accurate it is. You may have noticed this yourself. The next time you are retelling a story, notice what you add, or what your brain wants to add, to the account. You may also notice that you drop certain details from previous tellings of the story.With individual memories all jumbled up with each other, it is hard to believe we ever know anything to be true. Did you really break your mother's favorite vase when you were three? Was that really your father throwing rocks into the river with you when you were seven? The human brain may be quite remarkable indeed.
