Select one or more expressions that together represent all solutions to the equation.
sin(x)=-0.7
Answers
Answer:
A. [tex]x_{1} = -44.427^{\circ}\pm n\cdot 360^{\circ}[/tex]
B. [tex]x_{2} = -135.573^{\circ}\pm n\cdot 360^{\circ}[/tex]
Step-by-step explanation:
The negative value of the sine function indicates that [tex]x[/tex] is located at third and fourth quadrants. Besides, this function has a period of 360º. There are two families of solutions:
[tex]x_{1} = \sin^{-1} (-0.7)[/tex]
[tex]x_{1} = -44.427^{\circ}\pm n\cdot 360^{\circ}[/tex]
[tex]x_{2} = \sin^{-1} (-0.7)[/tex]
[tex]x_{2} = -135.573^{\circ}\pm n\cdot 360^{\circ}[/tex]
Hence, right answers are A and B.

Mr. Simpson feeds his dog 1⁄2 of a cup of dog food each day. How long will 4 cups of dog food
last?
Answers
Answer: 8 days
Step-by-step explanation: Get out your calculator. Put in 1/2, did you get .5? You should've gotten .5. Now if you put in 4 / .5, then you'll get 8. Seems pretty simple I guess. Lmk if this helped you.
The dog food last for 8 days.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Mr. Simpson feeds his dog 1⁄2 of a cup of dog food each day.
Total cups of food= 4
So, 4 cups of dog food lasts
= 4/ (1/2)
= 4 x2
= 8
Hence, the dog food last for 8 days.

Solve for x. (Enter your answers as a comma-separated list.)
Answers
Answer:
x=1
Step-by-step explanation:
The value of x is 1 for the given determinant.
The determinant is defined as a scalar value that is associated with the square matrix. If X is a matrix, then the determinant of a matrix is represented by |X| or det (X).
Given a determinant value equal to zero,
To calculate the value of x,
Firstly, calculate the determinant as follows and equate it to zero:
[tex]1(3 \times-2-(-4\times3))-x(1 \times-2-3 \times0)+2(1\times-4-0\times3)=0\\\\[/tex]
[tex]1(-6+12)-x(-2)+2(-4)=0\\\\[/tex]
[tex]6+2x-8=0\\[/tex]
Solve like terms together and try to separate variable on LHS, so that it becomes easy to calculate the value of it.
Thus, the value of x is 1.

PLEASE HELP, I DON'T UNDERSTAND THE WORDING
Answers
Answer:
C. 8 miles per hour
Step-by-step explanation:
It takes Diego [tex]\frac{1}{8}[/tex] of an hour to complete the lap = [tex]\frac{1}{8}[/tex] x 1 hour = [tex]\frac{1}{8}[/tex] hour
Distance of the track = 1 mile long
The speed of an object expresses the ratio of distance moved to time taken to cover the distance.
i.e speed = [tex]\frac{distance}{time taken}[/tex]
= [tex]\frac{1}{\frac{1}{8} }[/tex]
= 8
Speed = 8 mile per hour
Therefore, Diego's bike has a speed of 8 miles per hour.
