We always follow these rules when we are Multiplying and Dividing numbers with Scientific Notation.
1. If the numbers are not in scientific notation, convert them.
2. Regroup the numbers using the commutative and associative properties of exponents.
3. Now multiply the two numbers written in scientific notation, you work out the coefficients and the exponents separately.
-Use the product rule; aⁿ × aᵇ = a⁽ⁿ⁺ᵇ⁾ to multiply the bases.
4. If the product of the coefficients is greater than 9, convert it to scientific notation and multiply by the new power of 10.
5. Join the new coefficient to the new power of 10 to get the answer.
--------------------------------------------------------------------------------------------------------------
Let's start!
Our equation:
(5.2 × 10⁶)(7 × 10⁸)
--------------------------------------------------------------------------------------------------------------
1. If the numbers are not in scientific notation, convert them.
They are in scientific notation, so we go on to step 2.
2. Regroup the numbers using the commutative and associative properties of exponents.
(5.2 × 7)(10⁶ × 10⁸)
3. Now multiply the two numbers written in scientific notation, you work out the coefficients and the exponents separately.
-Use the product rule; aⁿ × aᵇ = a⁽ⁿ⁺ᵇ⁾ to multiply the bases.
5.2 × 7 = 36.4
10⁶ × 10⁸= 10⁽⁶⁺⁸⁾ = 10¹⁴
4. If the product of the coefficients is greater than 9, convert it to scientific notation and multiply by the new power of 10.
36.4 = 3.64 × 10¹
5. Join the new coefficient to the new power of 10 to get the answer.
3.64 × 10¹ × 10¹⁴
3.64 × 10⁽¹⁺¹⁴⁾ = 3.64 × 10¹⁵
==================================================================
3.64 × 10¹⁵

Given right triangle ABC with altitude BD drawn to hypotenuse AC. If BC=6 and DC=4, what is the length of AC ?
Step-by-step explanation:
BC^2 + DC^2 = AC^2
6^2 + 4^2 =AC^2
36 + 16 = AC^2
52=AC^2
√52=AC
AC=7.2111
factorise fully :
4(x - y)^2 - 9(x + y)^2
Answer:
- ( 5x + y ) ( x + 5y )
or
-5x^2 - 5y^2 - 26xy
Answer:
Step-by-step explanation:
4(x^2-2xy+y^2)-9(x^2+2xy+y^2)
4x^2-8xy+4y^2-9x^2-18xy-9y^2
-5x^2-26xy-5y^2
-5x^2-xy-25xy-5y^2
-x(5x+y)-5y(5x+y)
(-x-5y)(5x+y) or you can also remove the negative one to get
-(x+5y)(5x+y)

Solve for x
Literally forgot how to do this..
Answer:
x = 114 ur welcome
Step-by-step explanation:
Answer:
x = 114
Step-by-step explanation:
Given
[tex]\frac{x+18}{4}[/tex] = 33 ( multiply both sides by 4 to clear the fraction )
x + 18 = 132 ( subtract 18 from both sides )
x = 114
which equation represents the graph below
A. y= x^2 + 3
B. y= -x^2 + 3
C. y= -x + 3
D. y= -x^2
Answer:
B
Step-by-step explanation:
The y-intercept is 3 and the parabola is facing down which means the x^2 has to be negative.
ALEGBRA 1 ! help. me. please. this. is. so. hard. i dont. understand it.
Answer:
Part a) to find the maximum height of the snowball, you have to differentiate the function. Therefore you get ----> dh/dt= -32x-8 . Now equate this to zero and solve for x. x= (-1)/4 now sub this value in to find h(x) [note: i'm talking about the original function] . I got h max = h((-1)/4) = 9 which is the max height.

A triangle has a perimeter of 13x-21 units. One side is 4x+3 units. The other side is 5x-8 units. Write an expression to find the missing side.
Answer:
4x - 16
Step-by-step explanation:
A triangle is a three sided polygon with three edges and three vertices. the sum of angles in a triangle is 180 degrees
the perimeter of a triangle = sum of the side lengths
let the unknown length be represented with y
13x - 21 = 4x + 3 + 5x - 8 + y
13x- 21 = 9x - 5 + y
Make y the subject of the formula
13x - 21 - 9x + 5 = y
4x - 16 = y
the side length = 4x - 16

Answer:
B) y = 0.25x +5
Step-by-step explanation:
The x-value differ by 1, so the slope is the difference in y-values.
Comparing for x=2 and x=3, we see that the y-value increases by 0.25 from 0 to 0.25. This is the slope of the data in the table.
The equation with the same slope will have 0.25 as the x-coefficient. The equation of choice B is the one you're looking for.
y = 0.25x +5
_____
You don't care about the equation of the table, but it is ...
y = 0.25x -0.5
