Explain how to convert from scientific notation to standard form, then give the answer in standard form.

Answers

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.

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?

Answers

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.

PLZ HELP only got 30 minutes left will brainliest. What is the rate of change of the function? –2 --1/2 1/2 2

Answers

Answer:

[tex]-2[/tex]

Step-by-step explanation:

To find the rate of change of a function, we are looking for it's slope.

We can find the slope of a line by seeing it's rise over run.

Basically - how much the line's y increases divided by how much the line's x increases.

We can see that the y drops from 1 to -1 in 1 x value. This means the change in y is [tex]1 - (-1) = 2[/tex], however in this case it is -2 as we are dropping.

The change in x is 1 .

This means that the slope (rate of change) is [tex]\frac{-2}{1} = -2[/tex].

Hope this helped!

The answer is -2! :)

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
