It is more effective if I explain using examples. So, for multiplication, you just have to multiply the magnitude, then add the exponents of the base 10. For example, when you multiply 5.2×10³ and 1.6×10², the solution would be:
(5.2)(1.6)(10³⁺²) = 8.32×10⁵
Now, for division, you will have to divide the magnitudes, and subtract the exponents by numerator minus denominator. The solution is as follows:
(5.2/1.6)(10³⁻²) = 3.25×10¹
Answer:
* = b²
Step-by-step explanation:
You know that the square of a binomial is of the form ...
(x + y)² = x² + 2xy + y²
Matching given terms, we have ...
49 = y²
2xy = 14b
Solving the first of these relations for y, we have
y = √49 = 7
Putting that in the second relation and solving for x, we find ...
2x·7 = 14b
14x = 14b
x = b
Then the first term of the expansion, x², will be b².
The missing term is b².
To count the outside if a shape
Answer:
y = 3/5x - 6
Step-by-step explanation:
Slope intercept Form: y = mx + b
m = slope
b = y-intercept
Slope = 3/5
Y-intercept = -6
y = 3/5x - 6
Answer: 81 cm
Step-by-step explanation:
You would get this because if 1 cm = 4 meters than divide 324 meters by the 4 meters to find how many cm there is and you will get 81 cm hope this helps and have a good day
