How can transformations show that two images are congruent?

Mathematics

s2008m [1.1K]3 years ago
8 0

Step-by-step explanation:

Rotations, reflections, and translations are isometric. That means that these transformations do not change the size of the figure. If the size and shape of the figure is not changed, then the figures are congruent.

I hope it's helpful!

Gail practices swimming for 1 and 1 fourth hours swimming every day how much time does she practice in a week
Lorico [155]
If Gail practises swimming for 1 and 1/4 hours a day, then in a week she'll do:

1 1/4 * 7 = 5/4 * 7 = 35/4 = 8 3/4 [hours]

In other words she'll practice 8 hours and 45 minutes a week (assuming that she's still practicing on weekends).

[Function Composition] could someone help me with this answers or show work either is fine
zavuch27 [327]

Answer:

21

Step-by-step explanation:

Given the following expressions

f(x) = x³-2x

g(x) =-x-2

We are to find (fog)(-5)

fog = f(g(x))

f(g(x)) = f(-x-2)

Replace x with -x-2 in f(x)

f(-x-2) = (-x-2)³-2(-x-2)

f(-x-2) = (-x-2)³+2x+4

fog = (-x-2)³+2x+4

Substitute x = -5 into the result

fog(-5) = (-x-2)³+2x+4

fog(-5) = (-(-5)-2)³+2(-5)+4

fog(-5) = (5-2)³-10+4

fog(-5) = 3³-6

fog(-5) = 27-6

fog(-5) = 21

Hence the required result of the composite function is 21

Which statement is true about the function f(x)= squared root negative x?
Liono4ka [1.6K]
The answer is the first option: it has the same domain as the function f(x) = - √(-x).

The domain is the set of x-values for which the function is defined.

The square root function is defined only for zero and positve values.

- x is positive when x negative.

So the domain for - √(-x) and √(-x) are the same: x less than or equal to zero.
