Let f(x)=10x . which function represents a transformation of f(x) by a vertical stretch with factor 1.25? g(x)=100.8x g(x)=1.25⋅10x g(x)=0.8⋅10x g(x)=101.25x

Option B

Explanation:

the given function f(x)= 10x when stretch vertically with the factor 1.25 will give g(x) = 1.25.10x

option A and C are totally irrelevant

Option D is incorrect because two numbers 10x and 1.25 when added will not give 101.25x instead it will give 10x +1.25

and we will multiply them not add them.

Note: If a function is compressed then we divide the function by the given factor.

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
