The total surface area of the cylinder in terms of π is 96π cm². The correct option is the second option 96π cm²
Calculating Total surface area of a CylinderFrom the question, we are to determine the total surface area of the cylinder
The total surface area of a cylinder can be calculated by using the formula,
T.S.A = 2πr² + 2πrh = 2πr(r +h)
Where r is the radius
and h is the height
From the given information,
h = 8 cm
r = 4 cm
Putting the parameters into the formula, we get
T.S.A = 2π×4(4 +8)
T.S.A = 8π(12)
T.S.A = 96π cm²
Hence, the total surface area of the cylinder in terms of π is 96π cm². The correct option is the second option 96π cm²

Find the area of the figure. (Sides meet at right angles.)
Answer:
44ft^2
Step-by-step explanation:
Break the shape into 3 rectangles, two 3 by 2's and one 4 by 8. (Get 4 by subtracting 3 from 7 for the left and right most side)
3 x 2 = 6 ft^2
since there's two rectangles you end up 6 + 6 so you get 12 ft^2
then 4 x 8 = 32 ft^2
add 32 and 12, get 44 ft^2
What is the value of x?
Answer:
108
Step-by-step explanation:
x and 2/3 x are linear pair angles.
Sum of linear pair angles is 180.
x + 2/3 x = 180
3x/3 + 2x/3 = 180
( 3x + 2x )/3 = 180
5x/3 = 180
Cross multiply,
5x = 180 * 3
Divide 5 on both sides,
x = ( 180 * 3 )/5
= 36 * 3
x = 108

Simplify this square root question
The simpliication of the expression is:
[tex]\frac{3 + 5x}{\sqrt{96}*x - \sqrt{x} }[/tex]
How to simplify the expression?
We have the expression:
[tex]\frac{3 + 5\sqrt{x^2} }{4\sqrt{6x^2} - \sqrt{x} }[/tex]
Remember two things:
[tex]\sqrt{x^2} = x\\\\\sqrt{A*B} = \sqrt{A} *\sqrt{B}[/tex]
So we can rewrite the expression as:
[tex]\frac{3 + 5\sqrt{x^2} }{4\sqrt{6x^2} - \sqrt{x} }\\\\\frac{3 + 5x}{\sqrt{96}x - \sqrt{x} }[/tex]

Determine the period.
Acellus!!! Please help
Reason:
The first peak is at x = 0. The next peak over is at x = 1. The difference is 1-0 = 1 which is the period.
The period is the amount of time needed to repeat the cycle.
The first peak occurs at x = 0, and the next peak occurs at x = 1. The difference between these two points is 1, which represents the period of the function.
The period of a function can be determined by finding the difference between two consecutive peaks or troughs.
To determine the period step by step, we start by identifying the first peak or trough of the function. In this case, it is x = 0.
Then, check for the next peak or trough, which is x = 1.
The difference between these two points gives the period, which is 1 unit of time.
The period represents the length of time required for the function to complete one full cycle and repeat itself. It is an important concept in understanding the periodic behavior of functions.

Find the vertex and the axis of symmetry for the following functions.
a) y = 2x^3 + 4x
b ) y= -x^2+4x-5
Answer:
b
Step-by-step explanation:
its correct
Step-by-step explanation:
a)
y = 2x³ + 4x
a polynomial of 3rd degree cannot have an axis of symmetry.
it can only have a point of symmetry, like in this case.
(0, 0) is the point of symmetry, because due to the fact there is no squared term, any negative x values create exactly the same values (in absolute values) as their positive counterparts - just negative.
the vertex of a polynomial of 3rd degree is the point where the function changes directions.
that point for x³ is the origin, as it is for x. the factors only stretch the graph, but the vertex stays the same.
only if we had a term like (x+a)³ in the polynomial, this would shift the vertex.
so, the point of symmetry and the vertex are the same :
(0, 0).
b)
y = -x² + 4x - 5
the vertex form of a quadratic function is
f(x) = a(x − h)² + k
with (h, k) is the vertex.
x = h is the axis of symmetry.
we use "complete the square" to get it into that form.
-x² + 4x - 5 = -(x² - 4x + 5) = -(x - 2)² - 1
therefore,
y = -(x - 2)² - 1
h = 2, k = -1
the vertex is (2, -1)
the axis of symmetry is x = 2
Consider the quadratic equation x2 10x 27 = 0. completing the square leads to the equivalent equation (x )2 = .
The solution to the given quadratic expression using the completing the square is x = ±√-2 -5
Completing the square methodThis is a method of factoring quadratic expression. Given the quadratic function.
x^2 + 10x + 27 = 0
Subtract 27 from both sides
x^2 + 10x = -27
Complete the square
x^2 +10x +5^2 = -27 + 25
(x+5)² = -2
x +5 = ±√-2
x = ±√-2 -5
Hence the solution to the given quadratic expression using the completing the square is x = ±√-2 -5
