Answer:

[tex]y=(750)1.05^t[/tex], where [tex]t[/tex] is the time (in years) from investment

Or  [tex]y=(750)1.05^{t-5}[/tex], where [tex]t[/tex] is the age of James

Step-by-step explanation:

exponential model:  [tex]y=ab^t[/tex],  where [tex]t[/tex] is the time (in years) from investment

when t = 0, y = 750

[tex]\implies 750=ab^0[/tex]

As [tex]b^0=1[/tex]

[tex]\implies 750=a[/tex]

Therefore, [tex]y=750b^t[/tex]

If the savings increase by 5% each year, then b = 105%.

105% = 105/100 = 1.05

Therefore, b = 1.05

So final model: [tex]y=(750)1.05^t[/tex], where [tex]t[/tex] is the time (in years) from investment

Or, we can write this as [tex]y=(750)1.05^{t-5}[/tex], where [tex]t[/tex] is the age of James

No, they are not

Step-by-step explanation:

Line segments are congruent if they have the same length. However, they need not be parallel. They can be at any angle or orientation on the plane.

Answer:

mean= m7.8571428571429  Mode 1, 2

Step-by-step explanation:

The mean, or average, is calculated by adding up the scores and dividing the total by the number of scores.    The mode of a data set is the number that occurs most frequently in the set. To easily find the mode, put the numbers in order from least to greatest and count how many times each number occurs. The number that occurs the most is the mode!

The the product of the initial amplitude and the exponential decay rate

of raised to the power of the time taken give the amplitude of 0.1 mm.

Correct option:

The given parameters are;

The initial amplitude = 0.75 mm

The decay rate, i = 25%

Required:

The time it takes the guitar to decay to 0.1 mm.

Solution:

The series of the sizes of the amplitude that has constant decay uses an

exponential decay formula.

When the amplitude is 0.1 mm, we have;

y = a·rⁿ

Where;

r = 1 - i

a = 0.75

n = The time taken

Which gives;

r = 1 - 0.25 = 0.75

y = 0.1 = 0.75 × 0.75ⁿ

[tex]\dfrac{0.1}{0.75} = \mathbf{0.75^{n}}[/tex]

n = 7.0

Answer:

y = 4x-7

Step-by-step explanation:

slope = difference of y-values / difference of x-values

= (9-5) / (4-3)

= 4/1

select a point to use in the slope-intercept form of a line:  y = mx + b where 'm' is the slope and 'b' is the y-intercept

(3,5)

5 = 4(3) + b

5 = 12 + b

-7 = b

slope is 4 and y-intercept is -7

y = 4x-7

Answer: C) 7 years

There's not much explanation other than I did an online search for the answer. Many sources I'm finding are saying "up to 7 years", which means that is the longest it will stay on the credit report.

Answer:

Step-by-step explanation:

Let p and w represent the speeds of the plane and the wind. The relation between time, speed, and distance is ...

  speed = distance/time

  p +w = (2565 mi)/(4.5 h) = 570 mi/h

  p -w = (2205 mi)/(4.5 h) = 490 mi/h

Adding these speeds, we get ...

  (p +w) +(p -w) = (570) +(490) mi/h

  2p = 1060 mi/h

  p = 530 mi/h

Then the speed of the wind is ...

  w = 570 mi/h -p = (570 -530) mi/h = 40 mi/h

The plane's speed is 530 mi/h; the wind speed is 40 mi/h.

275 / 6

Now put this over 100 to get the fractional part

275 / 6 // 100/1

Invert and multiply the denominator

275 / 6 * 1 / 100 = 275 / 600  You need to reduce this. Start by dividing numerator and denominator by 25

Answer:

x - 10 = -6

Step-by-step explanation:

9x + 12 = 48

Subtract 12 from both sides. 

9x + 12 = 48

      - 12  - 12

+ 12 and - 12 cancel out. 48 - 12 is 36. 

9x = 36

Divide 9 from both sides.

9x = 36

÷ 9  ÷ 9

9 ÷ 9 cancels out. x is left. 36 ÷ 9 is 4.

x = 4

Knowing x = 4, solve the equation.

x - 10 = ?

Plug in 4.

4 - 10 = -6

4 - 10 equals -6. This is your answer.

Hope this helped!

Answer:

i)

9x + 12 = 48

Add 6 to both sides (Addition property of equality)

3x=6

Divide both sides by 3 (Division property of equality)

x=2

Answer:

  1500 ft²

Step-by-step explanation:

The area of the triangle is given by the formula ...

  A = 1/2bh

For a base of 120 ft and a height of 25 ft, the area is ...

  A = 1/2(120 ft)(25 ft) = 1500 ft²

_____

Additional comment

As you can see from the attachment, the area from side lengths is different. The actual height is not 25 ft, but is closer to 24.65 ft.

Answer:

1500 ft

Step-by-step explanation:

Okay, so the function is to do x times 2, then subtract 4.

6 x 2 = 12, 12 - 4 = 8. The first one is 8.

2 x 2 = 4. 4 - 4 = 0.

-4 x 2 = -8. -8 - 4 = -12. The last is -12.

With this information we can tell that it is C, 8, 0, -12.

Answer:

Step-by-step explanation:

We can count two heads out of 3 coin tosses, this is 10 out of 25:

The experimental probability of getting exactly 2 heads out of 3 coin tosses is 40% option second is correct.

It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

The total outcome set

T = {HTT, HHH, HTH, THT, THH, THT, THH, THT, HHT, TTH, HHH, TTT, HHT, THH, HTT, HHH, THT, HTT, HHT, HTH, THH, HTT, THH, TTH, HTT}

n(T) = 25

Total favourable outcome n(E) = 10

The probability = 10/25 = 0.4

= 0.4×100 = 40%

Thus, the experimental probability of getting exactly 2 heads out of 3 coin tosses is 40% option second is correct.

Using Pythagoras' Theorem a² + b² = c², where a and b are the legs and c is the hypotenuse of a right triangle:

[tex]72^2+x^2=75^2[/tex]

[tex]\implies x^2=75^2-72^2[/tex]
