Let f(x) = sin 1 x. Then, the domain of f(x) is (-1,1] and the range is all real
numbers.
A. True
B. False
Answers
Option-B- False is the correct choice
We have a function - f(x) = sin x
We have to justify, whether the statement provided to is true or false.
Statement - the domain of f(x) is (-1,1] and the range is all real numbers.
What do you mean by domain and range of a function?For any function y = f(x), Domain is the set of all possible values of y that exists for different values of x. Range is the set of all values of x for which y exists.
We have -
[tex]f(x)=sin\;x[/tex]
Refer to the figure attached, the graph represents [tex]y=f(x)=sin\;x[/tex]. It can be seen that the domain of [tex]sin\;x[/tex] is between [1,1] (including both 1 and -1) and range of the function [tex]sin\;x[/tex] is all possible real numbers.
In the statement - it is mentioned that the domain is (-1, 1], including 1 and excluding -1, and range is all real numbers. But the domain of the function [tex]sin\;x[/tex] includes -1 in its domain. Hence the statement is false.
Hence, Option-B- False is the correct choice

Let's define the relation of Table B i.e R₂⇾We're gonna make a mapping diagram too here! [ See the attached picture }. Since one element ' 32 ' is associated to elements ' 35 & 12 ' of y , this is not a function.
Q. What do you mean by function ? How can we identify whether the given relation is function ?
Ans: Function is a special type of relation. Function is the refinement of relation. To be a function , In a relation from A to B, every elements of Set A should have only one ( distinct ) image in B. In other words , if no two different ordered pairs have the same first component , then it is a function.

Tony's class needs more than $500 for the school dance.
So far, they have raised $200. They plan to have a car
wash, charging $8 a car, to raise more money. Tony
solved the inequality 8x + 200 > 500, and determined
that if they wash 37 cars, they will have enough money.
Is he correct? Explain.
I’m posting this one last time PLEASE respond if you can as I need more than 1 answer and respond with the “Sample response” please!//
Answers
Answer:
No, Tony is not correct. Solving the inequality tells us that x is greater than or equal to 37.5 . Since the class must wash a whole number of cars, they need to wash at least 38 cars.
Step-by-step explanation:
This is the sample response
(I just took the assignment lol)
Answer:
The solution to the inequality is x Greater-than-or-equal-to 37.5.
For this situation, only whole number solutions make sense.

Step-by-step explanation:
3/2 = 4/3x + 2/3
Convert to common denominator
9/6 = 8/6x + 4/6
subtract 4/6 from both sides
9/6 - 4/6 = 8/6x + 4/6 - 4/6
5/6 = 8/6x
Divide by 8/6
5/6 x 6/8 = x
30/48 = x
x = 30/48

Answers
Answer:
go to photo math thank me later
Step-by-step explanation:
Answer: After “4 hours” of work will the store earn $68.
Step-by-step explanation: To find the answer you plug in 4 into all values of x in the equation it looks like this y = -8(4)^2 + 64(4) - 60. Once you multiply, the numbers it turns into is y = -128 + 256 - 60. Then. Once you do all the addition and subtraction you get y = $68.

If the circumference of a circle is 84.5 ft, find the radius.
Answers
Answer:
13.448, rounded off: 13.5 ft
Step-by-step explanation:
[tex]r=\frac{C}{2\pi }[/tex]
Where r = radius, C = circumference.
[tex]r=\frac{84.5}{2\pi } =13.448[/tex] = 13.5 ft
Answer:
r = 13.5 ft
Step-by-step explanation:
The circumference of a circle of radius r is C = 2(pi)r.
Here, C = 84.5 ft = 2(pi) r, or
C = 84.5 ft = 6.28r
Dividing both sides by 6.28 results in the value of r:
r = 84.5 ft / 6.28 = 13.5 ft

Step-by-step explanation: When we look at the table, we see that when x increases from -3 to 4 (change of +7), y increases from -3 to 1 (change of +4). When we increase x by 7 again to 11, we see that y again increases by 4. Since the function is increasing a constant rate (which is 4/7), we know that the function is linear.

Answer:
The center of the circle is at the coordinate: (1,6)
Explaination:
To find the answer all you need to do is add the x values together and divide by two and add the y values together and divide by two:
[tex]\frac{5-3}{2} =1[/tex] (x-values)
[tex]\frac{5+7}{2} =6[/tex] (y-values)
Therfore the center is at point (1,6)
Answer:
(1, 6 )
Step-by-step explanation:
The centre of the circle is at the midpoint of the diameter
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
( [tex]\frac{x_{1}+x_{2} }{2}[/tex], [tex]\frac{y_{1}+y_{2} }{2}[/tex] )
Here (x₁, y₁ ) = (- 3, 5) and (x₂, y₂ ) = (5, 7) , then
midpoint = ( [tex]\frac{-3+5}{2}[/tex], [tex]\frac{5+7}{2}[/tex] ) = ([tex]\frac{2}{2}[/tex], [tex]\frac{12}{2}[/tex] ) = (1, 6 )
The centre of the circle is (1, 6 )
