On evaluating the function at x = -8, we get -
f(-8) = 64.
We have a function -
f(x) = [tex]x^{2}[/tex]
We have to find the value of f(x) at x = -8.
Evaluate - f(x) = Sin( [tex]\frac{\pi }{x}[/tex] ) at x = 4.f(x) = Sin( [tex]\frac{\pi }{x}[/tex] )
f(4) = Sin( [tex]\frac{\pi }{4}[/tex] )
f(4) = [tex]\frac{1}{\sqrt{2} }[/tex]
According to the question, we have -
f(x) = [tex]x^{2}[/tex]
Now, evaluating the function at x = -8, we get -
f(- 8) = [tex](-8)^{2}[/tex] = -8 x -8 = 64
Hence, on evaluating the function at x = -8, we get -
f(-8) = 64.

What is eighty-three hundredths in standard form
Answer:
.83
Step-by-step explanation:
hundredths means it is a decimal
In fraction form, it means over 100
83/100
.83
Answer:
0.83
Step-by-step explanation:
Just look at the part where it says hundredths or has the "ths" and youl know how to write it. However, not all types of standard forms are the same some have "and" in them and that means that you should put a decimal point.
used to have a square garage with ft of floor space. recently built an addition to it. The garage is still a square, but now it has 50% more floor space. What was the length of one side of the garage originally? What is the length of one side of the garage now? What was the percent increase in the length of one side?
Answer:
Length of the original square garage = 16.7ft
Length of the new square garage= 20.5ft
Percentage increase in the length of the side = 23%
Step-by-step explanation:
Yossi used to have a square garage with 280 ft? of floor space. He recently built an
addition to it. The garage is still a square, but now it has 50% more floor space. What was the length
of one side of the garage originally? What is the length of one side of the garage now? What was the
percent increase in the length of one side?
Area of the original square garage = 280ft²
Area of a square = length²
280ft² = length²
Find the square root of both sides
√280ft² = √length²
16.7ft = length
Length of the original square garage = 16.7ft
Area of the new square garage = 280ft² + 50% of 280ft²
= 280ft² + 0.5 × 280ft²
= 280ft² + 140ft²
= 420ft²
Area of a square = length²
420ft² = length²
Find the square root of both sides
√420ft² = √length²
20.5ft = length
Length of the new square garage= 20.5ft
Percentage increase in the length of the side = (new - old) / old × 100
= (20.5 - 16.7) / 16.7 × 100
= 3.8 / 16.7 × 100
= 0.23 × 100
= 23%
Percentage increase in the length of the side = 23%

There will be around 1024 viruses, from single virus, in the system after 10 divisions. This is related to Linear equation.
Linear EquationIn the question we are provided with the information that the virus divides itself into two, at every time interval.
Hence, in the number system, we can write it down as 1, 2, 4, 8....to 10th divison. The linear equation will be 2(2)^n-1.
Where n is equal to number of divisions, and the value 2 is the virus bening multiplied by 2.
Hence the value after 10th division will be 2(2)^10-1

How do I simplify these expressions?
5(x+8)+3
3.6x-7-5.1x
4+8x+2.2-10x
Answer:
1. 5x +43
2. -1.5x - 7
3. 6.2 - 2x
Step-by-step explanation:
Equation 1:
5 (x+8) +3
First, we can distribute the 5 to the (x+8) and get 5x + 40. Distributing is when we multiply the 5 by the first number (x) and then by the second number (8) Because they aren't like terms (don't both have x's) we cannot combine then and must keep them separated by a subtraction sign
Now we have: 5x + 40 + 3
Next, we can combine the like terms. This means that any that have the same variable can be combined. So, the 5x has no other x's so he has to stay how he is. The 40 and the 3, however, can be added together to get 43.
Our finished equation is: 5x + 43
Equation 2:
3.6x - 7 - 5.1x
First, we can combine like terms as we learned in the last problem. This would be our x's since we have multiple.
We can add 3.6x and -5.1x and get -1.5x
Now we have: -1.5x - 7
Equation 3:
4 + 8x + 2.2 - 10x
We can start with either the numbers with x's or without but I'll just do the x's. So we have 8x and -10x. Adding these together would get us -2x.
Next, we can combine 4 and 2.2 and get 6.2.
Now, putting these back into our equation would look like this:
6.2 - 2x

Answer:
The area of a circle is [tex]\pi r^{2}[/tex] which is given in the question. (r is radius)
The radius is the length from the centre of the circle to the border of the circle (8cm in this case)
Area of circle:
[tex]\pi r^{2} =\pi *8^{2} =64\pi =201.06cm^2[/tex] (2 decimal places)
Circumference of circle:
[tex]\pi d[/tex] (d is diameter)
The diameter is twice the radius and it is the length of a point on the circle to the opposite point of it.

Is the square root of 58 a rational number
Answer:
The square root of 58 is a rational number if 58 is a perfect square.
Step-by-step explanation:
It is an irrational number if it is not a perfect square. Since 58 is not a perfect square, it is an irrational number. This means that the answer to "the square root of 58?" will have an infinite number of decimals. The decimals will not terminate and you cannot make it into an exact fraction.
is this what you needed or
The square root of the number is A = √58 is not a rational number
Given data ,
Let the first number be represented as p
where the value of p = 58
Now , the square root of the number is expressed as
A = √58
The radical form of a number refers to expressing a number using a radical symbol (√) to represent a root.
It is used to express the roots present in the number.
So , A = √58
On simplifying , we get
A = 7.6157731058639082856614110271583...
On further simplification , we get
A = the square root of 58 is not a rational number
Hence , the square root of 58 is an irrational number because it cannot be expressed as a fraction of two integers

2(19+w) + 2w= 66 distribute
38 + 2w + 2w = 66 add the w values

of people of the same sex and similar ages follow a Normal distribution reasonably closely. Weights, on the other hand, are not Normally distributed. The weights of women aged 20–29 in the United States have mean 161.9 pounds and median 149.4 pounds. The first and third quartiles are 126.3 pounds and 181.2 pounds, respectively. What can you say about the shape of the weight distribution? Why?
Answer:
Right-skewed
Step-by-step explanation:
The shape of the weight distributed is skewed, because the mean and the median are not equal.
Moreover, the distribution is right-skewed because the mean is greater than the median and because the mean is influenced by the tail of large values.

All pictures are below please help Sandi had the following problem on her math test: . She showed her work on the test as follows: Given: Step 1: Step 2: Step 4: Step 5: In at least two paragraphs, explain the steps Sandi took to arrive at her answer. If she made any errors in her process clearly explain what she did wrong and how she could have made the error. If there is an error, provide the correct steps in your explanation of Sandi’s work. Use correct math terminology wherever appropriate.
Answer/Step-by-step explanation:
The basic rule of maths operation used by Sandi, is the PEMDAS Rule.
Maths operations like the one Sandi was given must follow this rule. According to the rule:
P - Parentheses, solve everything you have in the parentheses first.
E - Exponents, do the exponents.
M - Multiplication or
D - Division operation should come next.
A - Addition or
S - Subtraction comes last.
Let's apply this rule to see if Sandi rightly applied the PEMDAS Rule:
Step 1:
6*4 + 2 ÷ 2 - 7 (given)
Step 2: perform operation involving Multiplication first according to PEMDAS Rule.
24 + 2 ÷ 2 - 7 (multiplication first. I.e. 6*4 = 24)
Step 3: perform division operation next.
24 + 1 - 7 (division operation. i.e. 2÷2 = 1)
Step 4: Subtraction
24 - 6 (i.e. +1 - 7 = -6) this is where Sandi made an error.
Step 5: subtraction
24 - 6 = 18.
Sandi made a mistake in step 4 and 5. Her addition and subtraction operation was wrong. 1 - 7 = -6 not +6.
During operation like this, either subtraction or addition can come first.
