Answer:
5.2 x 10^-2
Step-by-step explanation:
Scientific notation is used to simplify very large or very small numbers.
The formula for scientific notation is (a x 10^ n)
(a) is a number that is both greater than 1 and less than 10
(n) is the number of places the decimal place moves. This number can be positive or negative depending on the number you are converting. If the original number is greater than 1 (n) will be positive, and if the number is less than 1 (n) will be negative.
First you should write out the number.
0.052
Then, you should determine the number places the decimal point must move, and create a number greater than 1 and less than 10. (You should also pay attention to the direction the decimal point moves)
For this problem you will move the decimal place 2 places to the right to create the number 5.2.
Last, substitute the values into the formula. For this problem (a)= 5.2 and (n)= -2. This gives us the expression 5.2 x 10^-2.
Answer:
14x and 3 x
Step-by-step explanation:
14x and 3 x are like terms.
This is because they both have 'x'. (They can even be simplified)
Whereas unlike terms are terms which do not contain the same variable or numerical value. (They cannot be simplified with other terms than its like term)
To find the difference you would need to make the denominator equal so I changed it to 15 and the difference would be 7/15
<h2>
The circle (x − 7)² + (y − 8)² = 9 is a circle with center (7,8) and radius is 3</h2>
Step-by-step explanation:
Equation of circle with (h,k) as center and radius r is given by,
(x-h)²+(y-k)² = r²
Here we need to describe the circle given by the equation (x − 7)² + (y − 8)² = 9
Changing equation to (x-h)²+(y-k)² = r² form
(x − 7)² + (y − 8)² = 9
(x − 7)² + (y − 8)² = 3²
So, h = 7 , k = 8 and r = 3
Center is (7,8) and radius is 3
The circle (x − 7)² + (y − 8)² = 9 is a circle with center (7,8) and radius is 3
77/100, 81%, 0.84 because it equals 77% than 81% than 84%
