Scientific notation means to write the answer in standard form. standard form helps you to express numbers that are too big or too small to be conveniently written in decimal form.
so for this case, it will be 4.571×10^-4.
when the number is decimal, you move the dot to the right and it will always be multiplying 10 to the power of a negative power.

4.571 X 10^-4

you do this by moving the decimal until there is no zeros, to the left of the decimal point.

Answer: 15.2

Step-by-step explanation:

(14)^2 + (6)^2 = c^2

196 + 36 = c^2

232 = c^2

Square root both sides

15.231546 = c

What is the solution of the system? Use the elimination method. {4x+2y=182x+3y=15 Enter your answer in the boxes.
Oxana [17]
\left \{ {{4x+2y=18(1)} \atop {2x+3y=15(2)}} \right.
Lets multiply equation (2) by -2 to get:
-4x-6y=-30

Now we can add equations (1) and (2) to eliminate x:
\left \{ {{4x+2y=18}+ \atop {-4x-6y=-30}} \right.
-4y=-12
y= \frac{-12}{-4}
y=3
Now that we know the value of y, we can replace it in equation (1) to get the value of x:
4x+2(3)=18
4x+6=18
4x=12
x= \frac{12}{3}
x=3

We can conclude that both x and y are equal to 3.

Estimate then record the product $473x9
ladessa [460]
So because 9 and 10 are close to each other, and the fact that 10 is really easy to multiply by, you do 473 x 10 which is 4730, because you just add a 0 to the end. 
This means that an estimate is 4730 or if you want to be less specific, <4730, because 9 is less than 10. 
The actual product though is 4257.

IrinaVladis [17]
The distributive property is a simplification rule that does not change the value of an expression. Nothing need be done to the other side of the equation.

q = -4(3+x)
q = -4*3 -4*x . . . . . the -4 is distributed. The right side has not changed value.
