If the scale factor of my dilation is 4 , what is happening to my shape ?

Mathematics
1 answer:
anygoal [31]3 years ago
4 0

Answer:

The shape is the same

Step-by-step explanation:

we know that

A dilation is a non rigid transformation, that change the size but not the shape of the original  figure

so

If the dilation scale factor is 4, the figure size increases by 4, but the shape remains the same

Answer:

  a) P(t) = 6.29e^(0.0241t)

  b) P(6) ≈ 7.3 million

  c) 10 years

  d) 28.8 years

Step-by-step explanation:

a) You have written the equation.

  P(t) = 6.29·e^(0.0241·t)

__

b) 2018 is 6 years after 2012.

  P(6) = 6.29·e^(0.0241·6) ≈ 7.2686 ≈ 7.3 . . . million

__

c) We want t for ...

  8 = 6.29·e^(0.0241t)

  ln(8/6.29) = 0.0241t

  t = ln(8/6.29)/0.0241 ≈ 9.978 ≈ 10.0 . . . years

__

d) Along the same lines as the calculation in part (c), doubling time is ...

  t = ln(2)/0.0241 ≈ 28.7613 ≈ 28.8 . . . years

X-18 = 2 (X-25)
x-18 = 2x - 50
-18 = x - 50
32 = x

check
32-18 = 14 = 2(32-25) = 2*7

Hey! This is due at like 11 pm!
rewona [7]

Answer:

7

Step-by-step explanation:

Use the Pythagorean Theorem

a^2 + b^2 = c^2

a and b are either opposite or adjacent

c is the hypotenuse.

1. Look for the right angle. (the little box). The right angle "points" to the hypotenuse. In this case, the hypotenuse is 25.

2. Because we know the hypotenuse is 25. We know that 24 is our adjacent. Meaning our missing side is the opposite.

3. Plug in the numbers. 24^2 + b^2 = 25^2

4. Solve:

24^2 + b^2 = 25^2

576 +b^2=625

b^2 = 625-576

b^2 = 49

\sqrt{b^2} = \sqrt{49}

b = 7

Hope this helps! Lmk if you have questions.
