Which one is a scaled copy

Mathematics
1 answer:
Alexeev081 [22]3 years ago
3 0

Answer: D

Step-by-step explanation:

I believe it’s D because a scaled copy is similar to the original shape, but with different shapes. It might be C, but however in math, to make a scaled copy, you have to multiply length number with the same number. (Example: Length is 2, so the scaled copy is 4.)

I hope you have a good day.

Help please<br> This question is stressing me out
Delvig [45]

Answer:

Maximum: C= 6(5) + 2y or <u>C= 30 + 2y</u>

Step-by-step explanation:

X can be greater than or equal to 0, but can also be less than or equal to 5.

Y is greater than or equal to 0.

4 times x then subtracted by y is greater than or equal to 1.

Since X can't go higher than 5, the maximum is 5.

Y can be anything since it can be greater than or egual to 0 and either way it would be greater than one.

I hope I could help!

a lump sum of $2000 is invested at 4.2% compounded continuously. (a) write the function for the model that gives the future valu
katrin2010 [14]

The function for the model that gives the future value of the investment in dollars after t years is: f(t) = 2000.e⁰·°⁴²t

Give, a lump sum of $2000 is invested at 4.2% compounded continuously.

Hence we have:

P = $2000

rate of interest = 4.2%

years = t

we know that A = Pe^rt

Substitute the above values in the formula.

Amount = f(t)

f(t) = 2000.e⁰·°⁴²t

hence we get the function for the model that gives the future value of the investment is f(t) = 2000.e⁰·°⁴²t

Therefore we get the required function.
