Answer:
1=x
Step-by-step explanation:
The equation would be 2=3-√x *x
subtract 3 from both sides
-1=-√x *x
multiply x*x
-1=-√x^2
the square and the square root cancel each other out
-1=-x
1=x
Now to check the answer works.
2=3-√1*1
2=3-√1
2=3-1
2=2
solve for u will give brainly and thanks

Answer:Concept Development: We have learned why scientific notation is indispensable in science. This means that we have to
learn how to compute and compare numbers in scientific notation. We have already done some computations, so we
are ready to take a closer look at comparing the size of different numbers.
Step-by-step explanation:There is a general principle that underlies the comparison of two numbers in scientific notation: Reduce everything
to whole numbers if possible. To this end, we recall two basic facts.
1. Inequality (A): Let and be numbers and let > . Then < if and only if < .
2. Comparison of whole numbers:
a. If two whole numbers have different numbers of digits, then the one with more digits is greater.
b. Suppose two whole numbers and have the same number of digits and, moreover, they agree digitby-digit (starting from the left) until the
th place. If the digit of in the ( + )
th place is greater than
the corresponding digit in , then > .

A:
[tex]5^3*5^{-4}=5^{3-4}=5^{-1}=\frac{1}{5}[/tex] (It is a value between 0 and 1.)
B:
[tex]\frac{3^5}{3^{-6}}=3^{5-\left(-6\right)}=3^{5+6}=3^{11}=177147[/tex] (It is not a value between 0 and 1.)
C:

Step-by-step explanation: For the first question, you have to make a fraction IN-ORDER by putting the 5 on top and adding, because that's what it asked for. For the second question, you have to do it in-order and reduce it. Glad I can help.
Grandma's soup company packages tomato soup in cylindrical cans that have a base diameter of 8 centimeters and a height of 10 centimeters. Each can contains four servings. The company also wants to package the soup in new cans that contain one serving. If the height of the new cans will be 10 centimeters, what should be the base diameter of these new cans, in centimeters?
Answer
i would think 2 centimeter
Step-by-step explanation:
this would never really happen in my opinion the height and diameter would decrease. but if it takes 8 for 4 the it should take 2 for 1 because it looks like its doubling
The base diameter of these new cans will be 2 centimeters.
What is Ratio?The ratio is written as a/b when the second number in the ordered pair, b, is not equal to 0. A percentage is an expression that converts two ratios into an equal value.
Given, The tomato soup is packaged in cylinder cans with a base diameter of 8 centimeters and a height of 10 centimeters by Grandma's Soup Company. There are four servings in each can. Additionally, the business intends to put the soup in new single-serving cans. If the new cans have a 10-centimeter height then the diameter of the base is to find. Since,
The volume of the big cylinder can(V₁) = 3.14 * height of big cylinder * (radius of base of big cylinder)^2 = 3.14 * 10 * 8²
The volume of the small cylinder can(V₂) = 3.14 * height of small cylinder * (radius of base of small cylinder(r₁))^2 = 3.14 * 10 * r²
Since V₁ = 4 *V₂
3.14 * 10 * 8² = 4 * 3.14 * 10 * r²
16 = 4r²
r = 2
Therefore, These new cans will have a base diameter of 2 cm.

Answer:
Step-by-step explanation:
heres how to work out your problem
add 110.25 and 55.45
you would get 165.70
multiply 165.70 by 4.5
then you would get 745.65
745.65 is your answer =)
Answer:
359.775
Step-by-step explanation:
110.25 + 55.45 = 165.65 x 4.5 = 359.775

which things are functions and which aren't
Answer:
Vertical lines are not functions.(not functions )
Function with no arguments and no return value.
Function with no arguments and a return value.
Function with arguments and no return value.
Function with arguments and a return value.
Step-by-step explanation:
The equations y = ± x and x 2 + y 2 = 9 are examples of non-functions because there is at least one -value with two or more -values. The vertical line test is a great way to visualize a violation of the definition of a function.
Answer: the curved one is not a function because it is curved.

Explain how to convert from scientific notation to standard form, then give the answer in standard form.
Answer:
To convert scientific notation to standard form you would need to move the decimal point over the number of the places that the exponent indicates. If the exponent is negative you move the decimal to the left, and if the exponent is positive you move the decimal to the right.
Step-by-step explanation:
1.456*10^3 would be scientific notation.
The exponent is a positive 3, means that you move the decimal 3 places to the right.
1456 would be the standard form.
1.456*10^-3 would be scientific notation.
The exponent is a negative 3, means that you move the decimal 3 places to the left.
0.001456 would be the standard form.

What is Pythagorean Theorem?
Answer:
Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a2 + b2 = c2.
Step-by-step explanation:
solve for z
10z − 7z = 3
10z − 7z = 3
The answer is Z = 1
Answer:
z = 1
Step-by-step explanation:
10z - 7z = 3
collect like terms (10z and 7z)
10z-7z=3z
3z =3
divide for both sides
z = 1
