Answer:

yes , keiko is correct.

sin^(-1)x = -sin^1

ANEK [815]2 years ago

Answer:

Keiko is wrong

Step-by-step explanation:

Keiko is incorrect

When n is positive, 1^n will always be 1

but........ (-1)^n will not always be -1

This is because there are parenthesis around -1

So n is even, then it will be 1 not -1

For example, n = 4

You will do -1 * -1 * -1 * -1 which is 1 not -1

but if n = 3

You will do -1 * -1 * -1 which is -1

Therefore, the second statement is incorrect resulting in Keiko being wrong

Minchanka [31]

Answer:

5

Step-by-step explanation:

\because \triangle ACB \cong \triangle DCE... (given) \\\therefore \angle A \cong \angle D... (c.a.c.t)\\\therefore m\angle A = m\angle D\\\therefore 50\degree = 10x\\\\\therefore x = \frac{50\degree}{10}\\\\\huge \orange {\boxed {\therefore x = 5\degree}}

What is the correct definition for tan 0
Reptile [31]
tan\theta=\frac{sin\theta}{cos\theta}\\\\\\Look\ at\ the\ picture.\\\\In\ a\ right\ triangle:\\\\sin\theta=\frac{a}{c};\ cos\theta=\frac{b}{c};\ tan\theta=\frac{a}{b}\\\\\frac{sin\theta}{cos\theta}=\frac{\frac{a}{c}}{\frac{b}{c}}=\frac{a}{c}\times\frac{c}{b}=\frac{a}{b}=tan\theta

Describe the pattern below.What are the next two numbers? 1.64,3.28
Zigmanuir [339]

Answer:

see explanation

Step-by-step explanation:

note that 3.28 = 2 × 1.64

This could be a geometric sequence with common ratio r = 2

To obtain the next term multiply the previous term by 2

3.28 × 2 = 6.56

6.56 × 2 = 13.12

1.64, 3.28, 6.56, 13.56 ← first 4 terms in sequence
