I’m not sure what the answer is, just trying to get points.... but I hope you find your answer :)
Answer:
$30
Step-by-step explanation:
To find the original price, divide the new price by 0.8
24/0.8
= 30
So, the original price was $30
First find the slope of the given line. 6x+4y=3. Isolate y. 4y=-6x+3, y=-3/2x+3/4.
The slope is -3/2. A perpendicular slope would equal the negative reciprocal of -3/2, which is 2/3.
The answer would be any line with a slope of 2/3 (ie y=2/3x-1).
To check, graph the given and derived equation.
Answer:
The Y-intercept value for the regression equation is -2
Step-by-step explanation:
The linear regression has the form: y = a + b*x, where a is the Y-intercept and b is the slope. To find the a compute the following:
a = MY - b*MX
where MX and MY denotes mean for the X and the Y respectively. Replacing:
a = 6 - 4*2 = -2
The area of the circle is πr², ie. 144π.
The volume of the cilinder is 12×144π = 1728π cm³.
I vote for answer A.
