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

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.

LenKa [72]
Your answer is B. You multiply 5 by the exponents and 4^0 is just 1, so 4^45•1=4^45. Hope this helped!

Find the values of the missing sides in the parallelogram given.
natta225 [31]

Given:

m∠B = 44°

Let's find the following measures:

m∠A, m∠BCD, m∠CDE

We have:

• m∠A:

Angle A and Angle B are interior angles on same side of a transversal.

The interior angles are supplementary.

Supplementary angles sum up to 180 degrees

Therefore, we have:

m∠A + m∠B = 180

m∠A + 44 = 180

Subtract 44 from both sides:

m∠A + 44 - 44 = 180 - 44

m∠A = 136°

• m,∠,BCD:

m∠BCD = m∠A

Thus, we have:

m∠BCD = 136°

• m∠CDE:

Angle C and angle CDE form a linear pair.

Linear pair of angles are supplementary and supplementary angle sum up to 180 degrees.

Thus, we have:

m∠D = m∠B

m∠D = 44°

m∠CDE + m∠D = 180

m∠CDE + 44 = 180

Subract 44 from both sides:

m∠CDE + 44 - 44 = 180 - 44

m∠CDE = 136°

ANSWER:

• m∠A = 136°

,

•

,

• m∠BCD = 136°

,

•

,

• m∠CDE = 136°

ale4655 [162]

Answer:

The system that can be used is:

10x + 2y = 56

9x + 3y = 60

Step-by-step explanation:

We have that:

x is the price of a package of sugar cookies, y is the price of a package of oatmeal cookies.

Shaikha sold 10 packages of sugar cookies and 2 packages of oatmeal cookies for $56.

This means that:

10x + 2y = 56

Khalid sold 9 packages of sugar cookies and 3 packages of oatmeal cookies for $60.

This means that 9x + 3y = 60

System that can be used:

The system that can be used is:

10x + 2y = 56

9x + 3y = 60

david ran on a straight track. every time he ran 480m, he took a break. After 2 breaks, he still had to run 120 m to complete th
kipiarov [429]

Answer:

The distance of the playground is 540m

Step-by-step explanation:

Here, we are interested in calculating the length of the playground given the information in the question.

Where to attack the question from is the segment that states that he took a break after 480m and also had 2 breaks. Thus, the distance traveled would be 480 * 2 = 960 m

Now, to find the length of the track, we add the distance covered plus the distance uncovered. Mathematically that would be 960m + 120m = 1,080m

In the last part of the question, we are told that the track is twice as long as the playground. This means that the length of the playground or the distance of the playground is 1080/2 = 540 m
