Answer:

The base and height of the solid is 5.5cm

Step-by-step explanation:

Given

[tex]Surface\ Area = 181.5cm^2[/tex]

Required

Determine the dimensions that maximizes the volume

Let the base dimension be x and the height be h

The volume is calculated as:

[tex]Volume =x^2 * h[/tex]

[tex]Volume =x^2h[/tex]

181.5 =x^2h

The surface area (S) is calculated as this:

[tex]S = 2(x^2 + xh + xh)[/tex]

[tex]S = 2(x^2 + 2xh)[/tex]

[tex]S = 2x^2 + 4xh[/tex]

Substitute 181.5 for S

[tex]181.5 = 2x^2 + 4xh[/tex]

Make h the subject:

[tex]4xh = 181.5 - 2x^2[/tex]

[tex]h = \frac{181.5 - 2x^2}{4x}[/tex]

Substitute [tex]h = \frac{181.5 - 2x^2}{4x}[/tex] in [tex]Volume =x^2h[/tex]

[tex]V = x^2(\frac{181.5 - 2x^2}{4x})[/tex]

[tex]V = x(\frac{181.5 - 2x^2}{4})[/tex]

[tex]V = \frac{1}{4}(x)(181.5 - 2x^2)[/tex]

[tex]V = \frac{181.5x}{4} - \frac{2x^3}{4}[/tex]

[tex]V = \frac{181.5x}{4} - \frac{x^3}{2}[/tex]

To get the maximum, we differentiate V with respect to t and set the differentiation to 0

[tex]dV = \frac{181.5}{4} - \frac{3x^2}{2}[/tex]

Set to 0

[tex]0 = \frac{181.5}{4} - \frac{3x^2}{2}[/tex]

[tex]\frac{3x^2}{2} = \frac{181.5}{4}[/tex]

Multiply through by 4

[tex]4 * \frac{3x^2}{2} = \frac{181.5}{4} * 4[/tex]

[tex]2*3x^2 = 181.5[/tex]

[tex]6x^2 = 181.5[/tex]

[tex]x^2 = \frac{181.5}{6}[/tex]

[tex]x^2 = 30.25[/tex]

[tex]x = \sqrt{30.25[/tex]

[tex]x = 5.5[/tex]

Recall that:

[tex]h = \frac{181.5 - 2x^2}{4x}[/tex]

[tex]h = \frac{181.5 - 2 * 5.5^2}{4 * 5.5}[/tex]

[tex]h = \frac{181.5 - 60.5}{22}[/tex]

[tex]h = \frac{121}{22}[/tex]

[tex]h = 5.5[/tex]

So, we have:

[tex]h = 5.5[/tex]

[tex]x = 5.5[/tex]

Hence, the base and height of the solid is 5.5cm

Answer: T= 3.54

Step-by-step explanation:

Step 1

Given that

The time period, T, s doirectly proportional  to the square root of the length, d, of the pendulum, we have that

T  ∝  [tex]\sqrt{d}[/tex]

Introducing the constant of proportionality, we have that

T= K[tex]\sqrt{d}[/tex].

Step 2

When d=6, T=5, K =?

T= K[tex]\sqrt{d}[/tex].

5 = k[tex]\sqrt{6}[/tex]

5=  k x 2.44949

k =5/2.44949

k =2.041

Therefore, when d = 3 , T= ?

T= K[tex]\sqrt{d}[/tex]

T= 2.041 x [tex]\sqrt{3}[/tex]

T= 3.53511≈ 3.54

Answer:

[tex]e^{t}+4e^{-4t}[/tex].

Step-by-step explanation:

To find the Laplace inverse of the above problem, we have to first solve the problem as a partial fraction, hence:

[tex]\frac{5s}{s^2+3s-4}=\frac{5s}{s^2+4s-s-4} \\\\=\frac{5s}{s(s+4)-1(s+4)}\\\\=\frac{5s}{(s-1)(s+4)}=\frac{A}{s-1}+\frac{B}{s+4}\\\\= \frac{A(s+4)+B(s-1)}{(s-1)(s+4)}\\\\Hence:\\\\\frac{A(s+4)+B(s-1)}{(s-1)(s+4)}=\frac{5s}{(s-1)(s+4)}\\\\A(s+4)+B(s-1)=5s\\\\to\ find \ A,put\ s=1:\\\\A(1+4)+B(1-1)=5(1)\\\\5A=5\\\\A=1\\\\to\ find \ B,put\ s=-4:\\\\A(-4+4)+B(-4-1)=5(-4)\\\\-5B=-20\\\\B=4\\\\Hence:\\\\\frac{5s}{s^2+3s-4}=\frac{1}{s-1}+ \frac{4}{s+4}\\\\[/tex]

[tex]L^{-1} [\frac{5s}{s^2+3s-4}]=L^{-1}[\frac{1}{s-1} ]+L^{-1}[\frac{4}{s+4} ]\\\\But\ L^{-1}[\frac{1}{s-a} ]=e^{at}\\\\Hence:\\\\L^{-1} [\frac{5s}{s^2+3s-4}]=L^{-1}[\frac{1}{s-1} ]+L^{-1}[\frac{4}{s+4} ]=e^{t}+4e^{-4t}\\\\=e^{t}+4e^{-4t}[/tex]

Answer:

Statement 1: Quadrilateral PQRT; line QSV; line PTV line QV bisects line RT, and line OR is parallel to line PV

Statement 3: angle QSR is congruent to angle VST

Statement 5: Triangle RSQ is congruent to angle TSV

Reason 1: Given

Reason 2: If a line bisects a segment, then it divides the segment into two congruent segments.

Reason 4: If two lines are parallel, then the alternate interior angles are congruent.

Step-by-step explanation:

The first statement will always be your given statements.

The given result is proved by ASA congruence criteria.

Two triangles are said to be congruent when all of their corresponding sides and angles are equal. For this relation between two triangles, there are many criteria such as SSS, SAS, ASA and RHS.

The given problem can be solved in statement and reason form as follows,

In triangles ΔQSR and ΔTSV,

Statement                                                           Reason

1. ∠QRS = ∠STV                                        Alternate interior angles for QR║PV

2. RS = TS                                                 QV bisects Line segment RT

3. ∠QRS = ∠VTS                                      Vertically opposite angles

4. ΔQSR ≅ ΔTSV                                     Triangles are congruent by ASA

Thus, QS =VS due to corresponding parts of congruent triangles.

Hence, QS = VS is proved by the ASA criteria for congruent triangles.

Step-by-step explanation:

plug in the coordinates for x and y

Answer:

use formula of distance ;

Step-by-step explanation:

d = distance

(x_1, y_1) = coordinates of the first point

(x_2, y_2) = coordinates of the second point

so d is √((x_2-x_1)²+(y_2-y_1)²)

to find the distance between any two points.

taking A as x coordinate and B as y coordinate ie

A= [10,0]; B= [0,30]

[10 is x1 ,0 is y1 ]; [0is x2 and 30 is y2]

putting values in distance formula

√(0-10)²+(30-0)²

= √( -10 )²+(30)²

Answer:

slope intercept form.

Step-by-step explanation:

heres the slope intercept form: y=mx+b.

this equation is what you will use to plot lines on graphs, points etc.

the letter b represents the y-intercept, where the line crosses a number on the y intercept on the graph. for example, an initial payment of 30 dollars.

the mx represents slope, or rate of change. for example, paying 5 dollars an hour.

you wouldn't plug a number to the x, but instead the m, because you'd multiply the m with the x.

Based on your question, I think you are asking what slope is. Slope is the rate of change.

Hope this helps!

Answer:

The spring will stretch 4.1 inches

Step-by-step explanation:

Direct Proportions

A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:

y = kx

Where k is the constant of proportionality.

Let's call:

y = distance a spring stretches

x = weight attached to the spring

We know when x=80 pounds, y=6 inches, thus:

6 = 80k

Solve for k:

[tex]k=\frac{6}{80}=\frac{3}{40}[/tex]

The equation is now:

[tex]\displaystyle y = \frac{3}{40}x[/tex]

When x=55 pounds are attached:

[tex]\displaystyle y = \frac{3}{40}\cdot 55[/tex]

Calculating:

y = 4.1 inches

The spring will stretch 4.1 inches
