Answer:
x = -2bm/(m²+1)
Step-by-step explanation:
One line has equation
... y = mx + b
The slope of the perpendicular line is the negative reciprocal of the slope of the original line. The perpendicular line with the opposite y-intercept has equation
... y = (-1/m)x - b
The point of intersection is where the x- and y-values are equal, so ...
... mx + b = (-1/m)x - b
... (m +1/m)x = -2b . . . . . . . add 1/m - b to both sides
... (m²+1)x = -2bm . . . . . . . multiply by m
... x = -2bm/(m²+1) . . . . . . divide by the coefficient of x
Answer:
A
Step-by-step explanation:
F test is a statistical method used to determine which models best fits the population from which the sample is derived. It is a ratio of two variances. Variance measure the rate of dispersion
The formula for calculating f-test = explained variance / unexplained variance
There are two hypothesis in an f test :
1. the null hypothesis - all slope coefficient are equal to zero
the alternative hypothesis : at least one of the slope coefficient is not equal to zero
Answer:
The answer to your question is 2⁸x²⁰ y²⁴ or 256x²⁰y²⁴
Step-by-step explanation:
Data
(2x³y³)⁴ (2x²y³)⁴
To solve this problem, use the law of exponents.
1.- Use the law of Power of a power rule
(2x³y³)⁴ (2x²y³)⁴ = (2⁴x¹²y¹²) (2⁴x⁸y¹²)
2.- Use the multiplication rule
(2⁴x¹²y¹²) (2⁴x⁸y¹²) = 2⁸x²⁰ y²⁴
3.- The answer is 2⁸x²⁰y²⁴ or we can simplify more like
256x²⁰y²⁴
