The solution for the scientific notation will be 3.6 x 10⁻¹¹.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the scientific notation is calculated as below,
E = (4x 10⁻⁵) (9x 10⁻⁵)
E = ( 4 x 9 ) ( 10⁻⁵ x 10⁻⁵ )
E = 36 x ( 10⁻¹⁰)
E = 3.6 x 10⁻¹¹
Therefore, the solution for the expression will be E = 3.6 x 10⁻¹¹.

Jenny watched a movie about aliens who never stop growing. Every alien is 10 centimeters tall at birth and grows exactly 8 centimeters each year. Let y represent the number of years since birth and h represent the alien's height in centimeters. Complete the equation that represents the relationship between y and h. y h 4 42 5 50 6 58 7 66
Answers
Answer:
h = 10 + 8y
Step-by-step explanation:
Given that :
Height of ght if all alien at birth = 10cm
Growth rate per year = 8 cm
Let:
y = number of years since birth
h = alien's height in centimeter
Relationship between h and y
h = Initial height + (growth rate per year*number of years)
h = 10 + 8y

e=mc squared, but solved for m. Thanks for any help!
Answers
Answer:
e/c=m
Step-by-step explanation:
To solve for "m" you need to isolate the variable. Since m is being multiplied by c you need to do the opposite operation, division. The Division Property of Equality tells us that we are allowed to divide the equation by any number as long as we divide it by both sides. So e/c=mc/c, then the c's cancel out, and your final answer is e/c=m.

We're left with a statement that is always true since 6 is always less than 9 regardless of what value of c we pick. So there are infinitely many solutions. Any real number can replace c to get a true statement.
