As per the given volume of cuboid, the length is 4 cm and the surface area of the cuboid is 5.76cm
The general formula to calculate the surface area of cuboid is written as,
SA = 2[lb + bh + hl]
where l refers the length, w refers width and h refers height.
Here we have given that a cube of side length 6 cm and has the same volume as that of a cuboid of height 3 cm and breadth 4 cm.
Now, we have to find the length and the surface area of the cuboid.
By the given value the Surface Area of Cube is calculated as.
=> 6s sq. = 6 x 4sq.
Then the value is 96 cm square
Then the Surface Area of Cuboid is calculated as,
=> 2(24+10h)=96
When we simplify the equation as
=> 24 + 10h = 48
=> 10h=24
Therefore, the value of h=2.4
Then the volume of Cuboid=6*4*2.4=5.76 cm.

chegg find the derivative of the function using the definition of derivative. State the domain of the function and the domain of its derivative f(x)
The derivative and domain of the function f(x) = x²-2x³ is :[tex](-\infty, \infty)[/tex].
What is derivative of the function (differentiation)?The slope of a function's graph or, more precisely, the slope of the tangent line at a point can be used to interpret a function's derivative.
Its computation actually stems from the slope formula for a straight line, with the exception that curves require the employment of a limiting procedure.
Calculation for the derivative:
Step 1: Use the definition of the derivative. Remember that f(x+h) means plug (x+h) into everywhere there is an "x" in f(x).
[tex]\begin{aligned}f^{\prime}(x) &=\lim _{h \rightarrow 0} \frac{f(x+h)-f(x)}{h} \\&=\lim _{h \rightarrow 0} \frac{(x+h)^{2}-2(x+h)^{3}-\left(x^{2}-2 x^{3}\right)}{h} \\&=\lim _{h \rightarrow 0} \frac{\left(x^{2}+2 h x+h^{2}\right)-2(x+h)(x+h)^{2}-x^{2}+2 x^{3}}{h} \quad \text { cancel } x^{2}\end{aligned}[/tex]
[tex]\begin{aligned}&=\lim _{h \rightarrow 0} \frac{\left(2 h x+h^{2}\right)-2(x+h)\left(x^{2}+2 h x+h^{2}\right)+2 x^{3}}{h} \\&=\lim _{h \rightarrow 0} \frac{\left(2 h x+h^{2}\right)-2\left(x^{3}+2 h x^{2}+h^{2} x+h x^{2}+2 h^{2} x+h^{3}\right)+2 x^{3}}{h} \\&=\lim _{h \rightarrow 0} \frac{2 h x+h^{2}-2 x^{3}-4 h x^{2}-2 h^{2} x-2 h x^{2}-4 h^{2} x-2 h^{3}+2 x^{3}}{h}\end{aligned}[/tex]
[tex]=\lim _{h \rightarrow 0} \frac{2 h x+h^{2}-6 h x^{2}-6 h^{2} x-2 h^{3}}{h}[/tex]
Step 2: Cancel out a factor of h from each term in the numerator with the h in the denominator. Then direct substitute h=0.
[tex]\begin{aligned}&=\lim _{h \rightarrow 0}\left(2 x+h-6 x^{2}-6 h x-2 h^{2}\right) \\&=2 x+0-6 x^{2}-6(0) x-2(0)^{2} \\&=2 x-6 x^{2}\end{aligned}[/tex]

The simplified form of the expressions: 4 2/7 - 2 1/3, 4.5 - 2 5/8 and 5 2/8 - 15% are 41/21, 15/8 and 51/10 respectively.
What are the simplified form of the expression?1) 4 2/7 - 2 1/3
First we convert the mixed fraction 4 2/7 and 2 1/3 into an improper fraction.
4 2/7 = (7×4 + 2 )/7 = 30/7
2 1/3 = (3×2 + 1 )/3 = 7/3
Hence,
30/7 - 7/3
( 30×3 - 7×7 )/21
( 90 - 49 )/21
41/21

First we convert both 4.5 and 2 5/8 into an improper fraction.
4.5 = 4 5/10 = (4×10 + 5)/10 = 45/10 = 9/2
2 5/8 = (2×8 + 5 )/8 = 21/8
Hence,
9/2 - 21/8
(9×8 - 21×2 )/16
(72 - 42 )/16
30/16
15/8

If Avogadro's number of pennies is divided equally among the 246 million men, women, and children in the United States, how many dollars would each receive
USD per person = $[tex]2.31[/tex] × [tex]10^{13}[/tex].
What is the US dollar?The US dollar is the official currency of the United States and a number of other countries. The Coinage Act of 1792 established the United States dollar on equal footing with the Spanish silver dollar, divided it into 100 cents, and authorized the minting of coins denominated in dollars and cents.To find how many dollars would each receive:
Avogadro's number of pennies is divided equally among 261 million people.
Avogadro's number is [tex]6.022[/tex] × [tex]10^{23}[/tex].
To find the number of pennies each person will receive, we divide [tex]6.022[/tex] × [tex]10^{23}[/tex] by 261 million.
Pennies per person = [tex]\frac{6.022 * 10^{23} }{261 million} = \frac{6.022 * 10^{23} }{261 * 10^{6} } = 2.31 * 10^{15}[/tex]
This is equal to the number of cents each person receives.
To convert pennies into dollars, 1 USD = 100 pennies, divide [tex]2.31 * 10^{15}[/tex] by [tex]100[/tex].
USD per person = [tex]\frac{2.31 * 10^{15} }{100} = $2.31 * 10^{13}[/tex]

Consider the two triangles. Triangles W U V and X Z Y are shown. Angles V U W and Y X Z are congruent. Angles U W V and X Z Y are congruent. Angles U V W and Z Y X are congruent. The length of side V W is 60 and the length of side Z Y is 48. The length of side Y X is 40 and the length of V U is 50. The length of side U W is 40 and the length of X Z is 32.
Two triangles are similar but not congruent if they have three congruent angles but the side lengths are not equal.
What is the congruency of triangles?
Congruent triangles are those of the same size and shape. This signifies that the respective sides are equal, as are the corresponding angles. We can determine whether two triangles are congruent without evaluating all of their sides and angles.To show how can the triangles be proven similar by the SSS similarity theorem:
The two triangles can be shown to be similar given that the ratios of the corresponding sides ΔWUV and ΔYXZ are constant
Reason:
Known parameters are:
ΔWUV and ΔXZY are shown:
∠VUW ≅ ∠YXZ
∠UWV ≅ ∠XZY
∠UVW ≅ ∠ZYX
Length of side VW = 60
Length of side VU = 50
Length of side UW = 40
Length of side ZY = 48
Length of side YX = 40
Length of side XZ = 32
The ratio of the sides are:
[tex]\frac{VW}{ZY} =\frac{60}{48} =\frac{5}{4} \\\frac{VU}{YX} =\frac{50}{40} =\frac{5}{4} \\\frac{UW}{XZ} =\frac{40}{32} =\frac{5}{4}[/tex]
Therefore, given that the angles of ΔWUV and ΔXZY are all congruent, and the sides of triangle ΔWUV and ΔXZY have a constant proportion, we have that the two triangles are congruent by the Side-Side-Side SSS congruency theorem, and we have:
ΔWUV ~ ΔYXZ given that ΔYXZ is a scaled drawing of ΔWUV.

Answer:
{x = -1 + √13 , x = -1 - √13}
Step-by-step explanation:
Completing the square:
f(x) = x² + 2x - 12
= x² + 2x + 1 - 1 - 12
= (x² + 2x + 1) - 1 - 12
= (x + 1)² - 13
Solving:
f(x) = 0
⇔ (x + 1)² - 13 = 0
⇔ (x + 1)² = 13
⇔ x + 1 = √13 or x + 1 = -√13
⇔ x = -1 + √13 or x = -1 - √13

Joanna has six beads that she wants to assemble into a bracelet. Two of the beads have the same color, and the other four all have different colors. How many different ways can Joanna assemble her bracelet
Joanna can assemble her bracelet in 30 ways.
How to find the number of ways in which the bracelet can be assembled?It is given that Joanna has 6 beads and of those 6 beads, 2 are of the same color.
The rest 4 are of different colors.
Six beads can be arranged in a circle in 6!/6 ways.
This means that the six beads can be arranged in 5! ways.
Since this is a bracelet, it can be flipped around. Therefore, it can be arranged in 5!/2 ways.
5!/2 = 5*4*3*2*1/2
= 60
Now, we know that two beads are of the same color. Therefore, we must divide this by two again.
Therefore, we get:
60/2 = 30
The six beads can be arranged in 30 ways to make the bracelet.
Therefore, we have found that Joanna can assemble her bracelet in 30 ways.

Drag an answer to each box to complete this paragraph proof. Given: Triangle ABC Prove: m/A= 66 A B (5x) By the C (x + 10) m/A+m/B +m/C= 180°. Using the the sum of the angles in a triangle is equal to 180°. Therefore, solve for x, first combine like terms to get 6x + 100 = 180. Using the (5x) +90° + (x + 10) = 180°. To 6x = 80. Then, using the division property of equality, x = 13. To find the measure of angle A, use the substitution property to get m/A = 5(13). Finally, simplifying the expression gets mA = 663"
The value of A has been illustrated, computed and proven based in the triangle given.
How to calculate the triangle?It should be noted that that a triangle is a shape that has three sides and the value of the addition of all the angles are equal to 180°.
Based on the information that's given, it should be noted that the value of angle A, angle B, and angle C will be equal to 180°.
In this case, the following can be deduced:
A = 5x
B = 90°
C = x + 10°
Therefore, A + B + C = 180° (sum of angles in a triangle)
5x + 90 + x + 10 = 180°
6x = 180° - 90° - 10°
6x = 80°
x = 80/6
x = 13 1/3
Therefore, the value of A will be:
= 5x
= 5 × 13 1/3
= 66 2/3
Therefore, A is 66 2/3.

The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.Using a calculator, the mean and the standard deviation for the diameters are given as follows:
[tex]\mu = 1.524, \sigma = 0.1226[/tex]
The 49th percentile is X when Z = -0.025, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]-0.025 = \frac{X - 1.524}{0.1226}[/tex]
X - 1.524 = -0.025 x 0.1226
X = 1.52.
