The lenght of a turtles shell z, in millimeters, is related to the turtles age in years a , as described by the equation below.

puteri [66]

Answer:

B, C , F

Step-by-step explanation:

The age multiplied 55, so the shell grows at rate of 55mm per year

in fact if the age is 2 we have (55 x 2) = 55 + 55

if 3 = (55 x 3) = 55 + 55 + 55

and so on

When the turtle is hatched the shell is 37 mm in lenght.

In fact, if we substitute 0 to a, we have

s = (55 x 0) + 37

s = 37

when the turtle is 1 year old, the shell is 92 mm in length.

in fact if we substitu a with 1, we have

s = (55 x 1) + 37

s = 55 + 37

s = 92

Manuel is riding his bike. The graph represents the distance Manuel travels from his house over time. Describe what is happening

olasank [31]

Answer:

Manuel is moving with a constant speed and reach his destination at 5 units distance from his house after 3 units of time.

He took rest at his destination for 4 units of time.

Then he reach his house at 5 units distance in 1 unit time.

Step-by-step explanation:

See the graph attached.

Manuel is riding his bike.

As the graph shows that Manuel starts his journey from his house and the time counts starts and then he is moving at a constant speed and reach his destination at 5 units distance from his house after 3 units of time.

The constant speed is $\frac{5}{3}$ units.

Then he took rest at his destination for 4 units of time.

After that, he again starts to move towards his house at a constant speed and reach his house at 5 units distance in 1 unit time.

Therefore, his speed of return is $\frac{5}{1}$ units. (Answer)
