Answer:
x = 2
x = -1.5
Step-by-step explanation:
The graph is of function f(x) = x²
Therefore, to find where the function intersects with y = 0.5x + 3,
equal the functions and solve for x:
⇒ x² = 0.5x + 3
⇒ x² - 0.5x - 3 = 0
Multiply both sides by 2:
⇒ 2x² - x - 6 = 0
Factor:
⇒ 2x² - 4x + 3x - 6 = 0
⇒ 2x(x - 2) + 3(x - 2) = 0
⇒ (x - 2)(2x + 3) = 0
Therefore:
(x - 2) = 0 ⇒ x = 2
(2x + 3) = 0 ⇒ x = -1.5
From looking at the ruler, the length of the segment is 6 cm.
I think the scale is 6 cm, and in inches that would be about 2 in, (2.3622) to be exact. For the sake of this problem I would just say 2 inches.
Answer:
Step-by-step explanation:
Formula
r = ∛(V/( pi * 4/3)) Invert the 4/3 and multiply the numerator by 4
Solution
r = ∛ 3 V / (4 pi )) Substitute values
r = ∛ 3 * 2304 / 12.56 4*pi = 4 * 3.14 = 12.56. Multiply 3 * 2304
r = ∛ 6912 / 12.56 Divide
r = ∛ 550.3187 Take the cube root
r = 8.195
64 percent is out of 100 which is 64/100 which simplifies down to 16/25 I believe
