damaskus [11]3 years ago

Answer:

Step-by-step explanation:

Since DE is parallel to AB, it means that Triangle CDE is similar to triangle CAB. This means that the ratio of the length of each side of ∆CDE to the length of the corresponding side of ∆CAB is constant. Therefore,

AB/DE = DC/CA

Therefore,

DE/40 = 15/24

Cross multiplying, it becomes

24DE = 40 × 15

24DE = 600

Dividing the left hand side and the right hand side of the equation by 24, it becomes

24DE/24 = 600/24

DE = 25

The relationship between triangle CDE and triangle CAB is similar triangles. This is because CD is parallel to AB as given.

Tell whether the table of values represents a linear function, an exponential function, or a quadratic funtion
gizmo_the_mogwai [7]

Answer:

Step-by-step explanation:

if it is linear then it will be a straight line(gradient is the same)

if quadratic then curve(gradeint isnt the same)

y=mx+c

m=[y(2)-y(1)]/[x(2)-x(1)]

you can choose any 2 points from the table

m=2-0.4/0-1

m=-1.6

repeat but 2 different coordinates

m=0.4-0.08/-1--2==>-2.24

m=-2.24

different coordinate therefore quadratic

cant be exponential, because nothing is being raised to some power
