kkurt [141]

Answer:

The answer is below

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, dilation and rotation.

Rigid transformations are transformation that produces an image with the same size, shape and angle as the original object. Rigid transformations are translation, rotation and reflection.

Dilation is not a rigid transformation.

All the transformations attached are rigid transformations.

Select the correct answer. Joshua likes to read. He read 6 books when he was 6 years old. Every year he doubled the number of bo

astra-53 [7]

Answer: C.186

Step-by-step explanation:

1. You know that he read 6 books when he was 6 years old and every year he doubled the number of books he read the previous year.

2. Let's call $n$ the number of book he read each year and $n_t$ the number of books he read between the ages of 6 and 10, then:

- At 6 years old:

$n=6$

- At 7 years old:

$n=6*2=12$

- At 8 years old:

$n=12*2=24$

- At 9 years old:

$n=24*2=48$

- At 10 years old:

$n=96$

The total books he read between the ages of 6 and 10 is:

$n_t=6+12+24+48+96\\n_t=186$

An ant went 2 meters away from its nest searching for food. The next time, the ant went 3 meters away. Each successive time the

seropon [69]

Answer:

The first time, the ant went 2m away, then we have a₁ = 2m

The second time, the ant went 3m away, then we have a₂ = 3m

The next time, the ant went a distance equal to the sum of the two previous ones, so we can write it in a general case as:

aₙ = aₙ₋₁ + aₙ₋₂

Only if n > 2.

then the third time, we have n = 3.

a₃ = a₂ + a₁ = 2m + 3m = 5m

a₄ = a₃ + a₂ = 3m + 5m = 8m

a₅ = a₄ + a₃ = 5m + 8m = 13m

This means that in the fifth trip, the ant went 13 meters away from its nest.

And if we consider the fact that the ant must go and return, then it will move a total distance of 13 meters two times, or 2*13m = 26 meters.
