Answer:
-1 is not in domain
0 and 2 both are in domain.
Explanation:
The radical function must have the domain greater or equal to 0. Here is why.
If we substitute any negative numbers in the equation
[tex]y = \sqrt{x} [/tex]
Then we would get the Imaginary Number, meaning it doesn't exist in Real Number system. That's why any negative real numbers cannot be part of the domain.
But that's for y = square root of x. There are like 4 types of radical function but this one is for example.
The equation in the question is the same type as the example equation.

A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 408.0 gram setting. It is believed that the machine is underfilling the bags. A 45 bag sample had a mean of 406.0 grams. A level of significance of 0.01 will be used. Is there sufficient evidence to support the claim that the bags are underfilled
Answers
Answer:
There is no sufficient evidence to support the claim that the bags are underfilled
Step-by-step explanation:
Null [H0] : chips x = 408
Alternate [H1] : chips x < 408
t = ( x' - u ) / (s / √n)
x' = sample mean , u = population mean, s = standard deviation, n = no. of observations.
(406 - 408) / (21 /√45)
-2 / 3.13
= 0.64
t value for α = 0.01 (one tailed), with degree of freedom = 44 : is 2.41
As calculated t 0.64 < tabulated t 2.41. So we don't reject the null hypothesis & state that chips x = 408

Answer:
44 degrees
Step-by-step explanation:
To start things off, we need to understand that all three triangles enclosed within the rectangle are identical, or better still, in this case, we can say that they are exactly the same.
This implies that the dimensions for the first triangle are the same as that f the second and the third.
we have the dimensions of the first triangle as 92 degrees, 44 degrees, and < DGA.
Recall that the sum of the angles in a triangle = 180 degrees.
< DGA = 180 - (92 + 44) = 44 degrees.
since the triangles are identical, < EHB = < DGA. = 44 degrees

Tammi deposited $520 into a bank account that earned simple interest each year. After 5 years, she had earned $156 in interest.
No money was deposited into or withdrawn from the account.
What was the annual interest rate?
Enter your answer in the box.
Answers
Answer:
6%
Step-by-step explanation:
Interest = Principal * rate * time
156 = 520(r)(5)
156 = 2600r
r = 0.06 or 6%
Answer:
6 percent
Step-by-step explanation:
Interest =1 Part
156 = 520(annual rate )(5)
156 = 2600(annual interest rate )
annual rate=156/2600
annual interest rate = 0.06
annual interest rate=0.06*100
annual interest rate =6%

What is the sum of the first five terms of the geometric series 3 − 6 + 12 − . . . ?
Answers
Answer:
33Step-by-step explanation:
The nth term of a geometric sequence is expressed as;
Sn = a(r^n - 1)/r - 1
a is the first term of the sequence
r is the common ratio
n is the number of terms
From the sequence;
a = 3
r = -6/3 = 12/-6 = -2
n = 5 (since are looking for the sum of first five terms)
Substitute into the formula;
S5 = 3((-2)^5 - 1)/-2 - 1
S5 = 3(-32-1)/-3
S5 = 3(-33)/-3
S5 = -(-33)
S5 = 33
Hence the sum of the first five terms of the sequence is 33

Sin(0)= cos(6) what is the value of 0?
Answers
We need to find Ο for : sin(Ο)= cos(6)
We know that:
cos θ =sin (90 - θ), so if we call θ = 6 then O will be:
O = 90 - θ
O = 90 - 6
O = 84The value of 0 is 84.
Given that,
Sin(0)= cos(6).
Based on the above information, the calculation is as follows:
cos θ =sin (90 - θ),
So in the case when θ = 6
So, O will be
O = 90 - θ
O = 90 - 6
O = 84

If you double the radius of a circle, then you will quadruple the circumference of the circle
Answers
Answer:
False
Step-by-step explanation:
No options is attached to the question. However, I'll assume it's a true or false question.
Represent the radius with r.
The circumference is calculated as:
X = 2πr
When the radius is doubled, the new radius R is
R = 2r
And the new circumference, C is:
C = 2πR
Substitute 2r for R
C = 2π * 2r
C = 4πr
Factorize the above equation.
C = 2 * 2πr
Recall X = 2πr;
The expression becomes:
C = 2 * X
C = 2X
This means that the circumference is doubled, not quadrupled.
Hence, the statement is false.

What is an expression?One mathematical expression makes up a term. It might be a single variable (a letter), a single number (positive or negative), or a number of variables multiplied but never added or subtracted. Variables in certain words have a number in front of them. A coefficient is the number used before a phrase.
Given:
An expression,
48/8 = 42/x
Applying cross multiplication,
x = 42(8)/48
x = 7
Therefore, the value of x is 7.

The length of a rectangular picture frame is 2 inches shorter than its width. If the perimeter of
the picture frame is 52 inches, what is the length, l, and width, w, of the frame? Write and
solve an equation to model the problem. Explain the meaning of the solution.
Answers
Answer:
Length = 12 inches
Width = 14 inches
Step-by-step explanation:
Formula for perimeter of a rectangle is;
P = 2(L + W)
Where;
L is length
W is width
We are told that the length is 2 inches shorter than its width. Thus;
L = (W - 2)
Thus,perimeter is now;
P = 2(W - 2 + W)
P = 2(2W - 2)
P = 4W - 4
We are told that the perimeter is 52. Thus;
4W - 4 = 52
4W = 52 + 4
4W = 56
W = 56/4
W = 14 inches
From L = (W - 2) ;
L = 14 - 2
L = 12 inches
