15 inches.......3 inches Which measurement is closest to the total surface area of the container in square inches?
Answers
Answer:
[tex]Area = 339.29\ in^2[/tex]
Step-by-step explanation:
Given
See attachment
Required
Determine the total surface area
From the attachment:
[tex]r = 3\ in[/tex] --- radius
[tex]h = 15\ in[/tex] --- height
The total surface area:
[tex]Area = 2\pi r(r + h)[/tex]
Substitute values for r and h
[tex]Area = 2\pi * 3(3 + 15)[/tex]
[tex]Area = 2\pi * 3(18)[/tex]
Remove bracket
[tex]Area = 2\pi * 3 * 18[/tex]
[tex]Area = 2\pi * 54[/tex]
[tex]\pi = \frac{22}{7}[/tex]
So, we have:
[tex]Area = 2 * \frac{22}{7} * 54[/tex]
[tex]Area = \frac{2 * 22 * 54}{7}[/tex]
[tex]Area = \frac{2376}{7}[/tex]
[tex]Area = 339.42[/tex]
Hence, the closest is:
[tex]Area = 339.29\ in^2[/tex]

Answer:
f(x) = 3(x - 2)² + 4
OR
f(x) = 3x² - 12x + 16
Step-by-step explanation:
Vertex form of a parabola:
y = a(x - h)² + kStandard form of a parabola:
y = ax² + bx + cLet's find the vertex of this parabola.
(h, k) → (2, 4)In order to find the a-value (vertex form), let's use another point besides the vertex on the parabola.
Using (3, 7) for (x, y), let's substitute this point and the vertex (2, 4) for (h, k) into the vertex form equation and solve for a.
7 = a[(3) - (2)]² + 4Simplify using PEMDAS.
7 = a(1)² + 47 = a + 4Subtract 4 from both sides.
a = 3Now we have (h, k) and a of the vertex form.
y = a(x - h)² + k → y = 3(x - 2)² + 4In order to convert from vertex to standard form, simplify the equation by FOILing.
y = 3(x - 2)² + 4y = 3(x² - 4x + 4) + 4Distribute 3 inside the parentheses.
y = 3x² - 12x + 12 + 4Combine like terms.
y = 3x² - 12x + 16Therefore, we have the answer:
Vertex form:
f(x) = 3(x - 2)² + 4Standard form:
f(x) = 3x² - 12x + 16x + 7 < 15

The domain refers to the x values used in the equation/graph. The line appears to go from -10 to 10 on the x-axis. The dots above -10 and 10 are not shaded in meaning those x values do not count towards the domain meaning we will use parenthesis instead of brackets for interval notation or no equal to signs in inequality notation.
Interval Notation: (-10, 10)

The cost of a mobile phone processor is directly proportional to its speed.
A 2GHz mobile costs £500.
Let x be the speed of a processor in GHz
Let y be the cost in pounds.
Find a formula linking the variables.
Answers
Answer: See explanation
Step-by-step explanation:
We are going to use the formula used in calculating direct proportion which is equal to:
y = kx
where,
x = speed of a processor in GHz
y = the cost in pounds
Therefore, y = kx
500 = 2k
Therefore, y = 2k
