HELP PLEASE!!

Mathematics
1 answer:
sattari [20]3 years ago
4 0

Answer: 1/3

Step-by-step explanation:

We know that after dilation with scale factor k the coordinates of pre-image (x,y) map to (kx,ky) of the image.

From the given graph, the coordinate of A =(9,4) and the coordinate of A' (3,2)

Then x = 9 and kx = 3

\Rightarrow k(9)=3\\\\\Rightarrow\ k=\frac{3}{9}\\\\\Rightarrow\ k=\frac{1}{3}

Therefore, the scale factor of the dilation is 1/3.

What is the average rate of change of f(x), represented by the table of values, over the interval [-3,4]
77julia77 [94]

Answer:

Average rate of change = 3

Step-by-step explanation:

  • We know that the average rate of change is basically a measure of the slope of the  secant line  in the closed interval [a, b].

here   a = -3 and b = 4

  • f(b) = f(4) = 27
  • f(a) = f(-3) = 6

⇒ Average rate of change = f(b) - f(a)  / b - a

                                            = (27 - 6) / (4 - (-3))

                                            = 21 / 7

                                            = 3

Therefore, Average rate of change = 3

(a): How many miles does the train travel per gallon?<br> (b):What is the slope of the graph?
drek231 [11]

since the graph has direct variation as data in x axis increases y also increases.

so we need to find how many miles travelled per galloon .

we distance travelled per gallon =total distance travelled/galoons of fuel used.

Distance travelled per gallon=200 miles/400 gallons=0.5 litres travelled per gallon

for part b) slope=rise/run

m=(y2-y1)/(x2-x1)

y2=400  y1=0 x1=0 x2=200

m=(400-0)/(200-0)=2

slope of the graph is 2
