A. Encuentre el
valor absoluto. por definición, el valor absoluto es la magnitud de un número real sin tener en cuenta su signo 1. | 120 | = 120 2. | -45 | = 45 3.
Step-by-step explanation:
By definition, the volume of a cylinder is given by:
V = π * r ^ 2 * h
Where,
r: radio
h: height
Clearing the height we have:
h = (V) / (π * r ^ 2)
Substituting values:
h = (7448π) / (π * (28/2) ^ 2)
Rewriting:
h = (7448) / ((14) ^ 2)
h = 38 cm
Answer:
The height in centimeters of the cylinder is:
h = 38 cm
Answer:
k = 5
Step-by-step explanation:
Calculate the slope m and then equate to 2
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (k, 3) and (x₂, y₂ ) = (6, k)
m = 
= 2 ( cross- multiply )
2(6 - k) = k - 3
12 - 2k = k - 3 ( subtract k from both sides )
12 - 3k = - 3 ( subtract 12 from both sides )
- 3k = - 15 ( divide both sides by - 3 )
k = 5
First you need to figure out how many hours he has been working for you, lets say h = 1 then you answer would be both A and B, if it is h = 2 then your answer is C, B, A, and maybe D (Because I am not really sure what D means)
Answer:
see explanation
Step-by-step explanation:
If there is a solution between x = 1.1 and x = 1.2 then there will be a change in sign when the equation is evaluated at the points, indicating the graph has crossed the x- axis, where the solution lies.
Given
x³ + 4x = 6 ( subtract 6 from both sides )
x³ + 4x - 6 = 0 ← in standard form
Evaluating for x = 1.1
(1.1)³ + 4(1.1) - 6
= 1.331 + 4.4 - 6 = - 0.269 ← < 0
Evaluating for x = 1.2
(1.2)³ + 4(1.2) - 6
= 1.728 + 4.8 - 6 = 0.528 ← > 0
Since there is a change in sign the graph has crossed the x-axis from below / indicating a solution between x = 1.1 and x = 1.2
