Whats is the sum of 4x10^-5 and 3x10^-5 written in standard form?

1 answer:

4 0

(4x10^-5) + (3x10^-5) would equal .00004 + .00003 = .00007

The way to convert scientific notation to standard notation is simple:

with negative powers, simply treat it as a whole number, subtract 1 from it and add that many zeros before the number you are multiplying by 10

with positive powers, simply subtract 1 from it and add that many zeros after the number you are multiplying by 10

Ted has $3.90. He has only dimes and quarters. He has 27 coins altogether. How many of each does he have

mestny [16]

Answer: 8 quarters 19 dimes

Step-by-step explanation:

we already know 8+19=27, if 4 quarters equals a dollar then you use 4 quarters each to create 2 dollars.

then, use 10 dimes to create another dollar summing it up to $3. now all we have to do is make 90 cents, and we've already used 18 coins.

if we used another 9 dimes, that would equal 90 cents.

in conclusion, 4+4= 8

8+10= 18

18+9= 27, and having $3.90

For f(X)=2x+1 and g(X)=x^2,find (f-g)(X)

Bezzdna [24]

The answer for f(x)-g(x) is $-x^2+2x+1$ .The solution can be obtained by use of concept of functions.

<h3>What is a function?</h3>

A function, in mathematics, can be defined as an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).It useful in mathematical representation of scientific quantities.

We can perform addition and subtraction operations on functions.

The given function f(x) and g(x) are

$f(x)=2x+1\\g(x)=x^2\\f(x)-g(x)=2x+1-x^2\\f(x)-g(x)=-x^2+2x+1$
