Answer:
By definition, the slope of a vertical line is undefined. Because the value of x is always equal to 4 it is never equal to 0 therefore there is no y-intercept.
Step-by-step explanation:
(2x + 1)^2 - 2(2x^2 - 1) = 4x^2 + 4x + 1 - 4x^2 + 2 = 4x + 3
The correlation is a weak positive correlation
Answer:166.7 milliliters
Step-by-step explanation:
height(h)=13cm
Radius(r)=diameter ➗ 2
r=7 ➗ 2
r=3.5cm
π=3.14
Volume=(π x r^2 x h) ➗ 3
Volume=(3.14 x (3.5)^2 x 13) ➗ 3
Volume=(3.14x3.5x3.5x13) ➗ 3
Volume=500.045 ➗ 3
Volume=166.7cm^3
1 cm^3=1mL
Therefore 166.7cm^3=166.7mL
In your question where as two metal sphere will be melted together to create a new single sphere and the radius is express as R of the new sphere function x and the answer is <span>4/3 * pi* (x^3 + (x+7)^3) = 4/3 * pi* R^3</span>
