Find the next two terms. 2, 10, 50, ?, ?

Answers

Hi there!

The next 2 terms are 250 and 1,250.

We have a geometric sequence, which means we use multiplication or division to get to the next term.

Here, we multiply by 5 to get to the next term.

So we multiply 50 by 5:

50*5=250

We multiply 250 by 5 to get to the next term:

250*5=1,250

And we're done!

Therefore, the next two terms are: 250 and 1,250.

Hope this helps!

~Just a felicitous girlie

#HaveASplendidDay

[tex]SilentNature :)[/tex]

Answer:

250, 1250

Step-by-step explanation:

This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by 5 gives the next term.

Hope that helps!

 Domain: (-∞, ∞)

Range: (0,∞)

Step-by-step explanation:

Exponential functions are curves which approach a horizontal asymptote usually at y=0 or the x-axis unless a value has been added to it. If it has, the curve shifts. This function has addition on the exponent but not to the whole function so it does not change the asymptote. Its y - values remain between 0 and ∞. This is the range, the set of y values.

However, the range of exponentials can change based on the leading coefficient. If it is negative the graph flips upside down and its range goes to -∞. This doesn't have it either.

The addition to 1 on the exponent shifts the function to the left but doesn't change the range.

In exponential functions, the x values are usually not affected and all are included in the function. Even though it shifts, the domain doesn't change either. Its domain is (-∞, ∞).

Domain: (-∞, ∞)

 Range: (0,∞)

Answer:

try graphing it to see the domain and range easier (desmos or a graphing calculator is useful)

Working together, Edward and Frances can wallpaper an apartment in 12 hours. It would take Frances 30 hours to do the same job by herself. How long would it take Edward to do it alone?

Answers

Answer:

Step-by-step explanation:

Givens

together: 12 hours

Frances: 30 hours

Edward: x

Formula

The formula is an odd one that shows up in physics as well.

1/Frances + 1 / Edward = 1/Together.

Solution

1/30 + 1/x = 1/12

LCD for 12 and 30

12: 2 * 2 * 3

30:3 * 2 * 5

LCD: 2*2*3*5

LCD: 60

2/60 + 1/x = 5/60               Subtract 2 / 60 from both sides

1/x = 5/60 - 2/60

1/x = 3/60                           Cross Multiply

3x = 60*1                            Divide by 3

3x/3 = 60/3

x = 20

So Edward (doing it alone) takes 20 hours to do the job.

Kaya invests £4000 for 8 years
The investment gets compound interest of x% per annum
At the end of 8 years the investment is worth £6872.74
Work out the value of x

Answers

To find the interest rate on the investment for 8 years is equal to 0.7%

Given the following data:

Principal = £4000Future value = £6872.74Time = 8 years

To find the interest rate on the investment for 8 years:

Mathematically, compound interest is given by the formula:

[tex]A = P(1 + r)^{t}[/tex]

Where;

A is the future value.P is the principal or starting amount.r is annual interest rate.t is the number of years for the compound interest.

Substituting the given parameters into the formula, we have;

[tex]6872.74 = 4000(1 + r)^{8}\\\\(1 + r)^{8}=\frac{6872.74}{4000} \\\\(1 + r)^{8}=1.7182\\\\1+r=\sqrt[8]{1.7182} \\\\1+r =1.07\\\\r=1.07-1\\\\r=0.7[/tex]

Interest rate, r = 0.7%
