Why does a calculator return an error when trying to find inverse sine of 1.055?

2 answers:

5 0

The calculator returns an error as the answer for the inverse sine of 1.055 because the acceptable range for sine is only from 0 to 1.00 in which 1.055 is clearly greater than. This is also the same as for the cosine values.

Answer:

Calculator shows error because maximum value of inverse of sin function can be one.

Step-by-step explanation:

The range of sin x is $-1$

So, it is of no use to find the value of $sin^{-1}(1.055)$

Because range is the value of the output of the function which is maximum 1 in case of sine and cosine function.

Calculator shows error because maximum value of inverse of sin function can be one.

Answer:

x=59/5 or x=11.8 depends on which one you want to do both are true

Step-by-step explanation:

Start with what you are given

angle 4= 5x+6 and angle 3=65 because lines m and n are both parallel angle4=angle3 in other words 5x+6=65

what you want to do is get x by itself.

1. Subtract 6 from both sides

5x+6-6=65-6

5x=59

2. Divide both sides by 5

5x/5=59/5

x=59/5

3. Check to see if you can simplify the fraction and if you teacher wants it in decimals or exact fraction.

x=59/5 or x=11.8 they are the same just ones a decimal the other is left as a fraction

A company is interested on average wages of employee and variance. A sample of 20 workers is taken and it is found that mean wag

vfiekz [6]

Given that the mean is $9.5 and the standard deviation is $1.30, the standard error will be given by:
σ/√n
where
σ-standard deviation
n=sample size

thus, we shal have:
1.30/√20
=0.2906
Next we find the margin error
0.2906*2=0.581
thus the confidence interval will be:
(9.5+0.581, 9.5-0.581)
=(10.081,8.919)

Calculate the angle of depression from the

s344n2d4d5 [400]

Answer:

angle of depression ≈ 53.8°

Step-by-step explanation:

the angle of depression is the measure of the angle from the horizontal downwards from the top of the flag pole.

this angle is alternate to ∠ A and is congruent to ∠ A

using the sine ratio in the right triangle

sin A = $\frac{opposite}{hypotenuse}$ = $\frac{25}{31}$ , then

∠ A = $sin^{-1}$ ( $\frac{25}{31}$ ) ≈ 53.8° ( to 1 d.p )

Angle of depression ≈ 53.8°

Does this table represent a function?why or why not

Alex787 [66]

The answer is C, because there are two different numbers correlated to the same number on the Y side. The table does not represent a function.

Answer:

8/3, or 2 if you want a whole number

Step-by-step explanation:

Well, the simple answer is 2/(3/4). This is nothing but 2*4/3, which is just 8/3. (I used the theorem that states that dividing is the same as multiplying by the reciprocal)
