Answer: option B
This is because you have to work out the range of both periods
The range is the highest number - the lowest number
Range for period 1: 92-81=11
Range for period 3:92-74=18
As you can see the range for period 3 is 7 points greater than period 1 therefore the answer is the second option ( option B)
Hope this helped
Answer:
= -5/4
Step-by-step explanation:
The slope through two points can be found by
m = (y2-y1)/(x2-x1)
= (-4-1)/(3--1)
= (-4-1)/(3+1)
= -5/4
Im pretty sure its (1, 4) if its wrong im so so sorry but I do think thats the awnser
Answer:
1. -18x¹¹
2. 3n⁷
Step-by-step explanation:
For these problems, there are two things you need to worry about: negative signs and exponents.
1. Let's look at the signs first. There is only one value with a negative sign, meaning that the negative sign will stay.
When multiplying with exponents, you have to add up the exponents. Don't forget the numerical coefficients.
-3x² · 3x · 2x³ · x⁵ = -18x¹¹
2. There are two negative signs in this probem, meaning that they will cancel out. Multiply the rest like we did in the first problem.
3n² · -n² · -n³ = 3n⁷
Step-by-step explanation:
x^3 is a perfect cube, 8 is a perfect cube, so we use difference of cubes.
Cube root of x^3 is x.
Cube root of 8 is 2
So
a=x
b= 2.
Set these equations equal to zero
If we do the discriminant, we get a negative answer so we would have two imaginary solutions,
Thus the only real root is 2.
If you want imaginary solutions, apply the quadratic formula.
