the table below represents the displacement of a turtle from its nest as a function of time.Part A. What is the y intercept of t

he function and what does it tell you about the turtle?part b. calculate the average rate of change of the function represented by the table between x = 1 to x = 4 hours and tell what the average rate represents.part c. what would be the domain of the function if the turtle continued to walk at this rate until it traveled 225 miles from the nest?

Part A.

Y intercept is the coordinate (0,y), when the function has an x value of 0, it is the y intercept.

In this case:

(0,5) =

y intercept = 5

IT tells about the turtle that it starts at a nest displacement of 5 miles.

Part B

The average rate of change represents the speed .

x1=1 ,y1=27

x2=4 ,y2=93

We have to calculate the slope if the function:

\text{slope}=\text{ }\frac{y2-y1}{x2-x1}

Replace:

\text{slope}=\frac{93-27}{4-1}\text{ = }\frac{66}{3}=22

Part C.

speed = distance /time

time= distance / speed

time= 225 / 22 = 10.22 hours

The domain will be

0< x ≤ 10.22

if a town with a population of 500 doubles in size ever 9 years, what will the population be 36 years from now?
s344n2d4d5 [400]

The population of the town in 36 years would be  8000.

<h3>What would be the population of the town in 36 years?</h3>

The formula that can be used to determine the town's population is:
FV = P (1 + r)^n

Where:

  • FV = Future value
  • P = Present value
  • R = rate of growth = 100%
  • N = number of years = 36/9 = 4

500 x 2^4 = 8000

Which graph shows the result of dilating this figure by a factor of 4 about the origin? On a coordinate plane, rectangle A B C D
Andrei [34K]

Answer:

Second option: On a coordinate plane, rectangle A'B'C'D' prime has points (-4,4),(12,4),(12,-4),(-4,-4)

(See the graph attached)

Step-by-step explanation:

For this exercise it is importnat to know that a Dilation is defined as a transformation in which the Image (The figure obtained after the transformation) has the same shape as the Pre-Image (which is the original figure before the transformation), but they have different sizes.

In this case, you know that the vertices of the rectangle ABCD ( The Pre-Image)  are the following:

A(-1,1)\\\\B(3,1)\\\\C(3,-1)\\\\D(-1,-1)

Therefore, to find the vertices of the rectangle A'B'C'D' (The Image)  that results of dilating the rectangle ABCD by a factor of 4 about the origin, you need to multiply the coordinates of each original vertex by 4. Then, you get:

A'=((-1)(4),(1)(4))=(-4,4)\\\\B'=((3)(4),(1)(4))=(12,4)\\\\C'=((3)(4),(-1)(4))=(12,-4)\\\\D'=((-1)(4),(-1)(4))=(-4,-4)

Finally, knowing those points, you can identify that the graph that shows the result of that Dilation, is the one attached.

Ainat [17]

Answer:

The probability that the first failure occurs among the five devices is given by

(a) 9 months =\frac{9}{15} or  =0.6

(b) 12 months=\frac{12}{15} or = 0.8

Step-by-step explanation:

probability is given as the; number of required outcome/ total number of possible outcome.

Nostrana [21]

Answer:

QR / SQ = SQ / TQ

Step-by-step explanation:

∠QST = 90 - ∠Q

∠R = 90 - ∠Q

∠QST = ∠R

ΔQST ~ ΔQRS

SQ / TQ = QR / SQ
