Way: W = k * w  * h^2/ L

4 tons is maximum weight that could be supported by a beam that is 6 inches wide, 2 inches high, and 24 feet long

Gravitational force of attraction on an object, caused by the presence of a massive second object, such as the Earth or Moon.

Given,

Maximum weight that a certain type of rectangular beam can support varies inversely as it’s length and jointly as its width and the square of its height.

beam 5 inches wide, 2 inches high and 10 feet long can support a maximum weight of 8 tons.

W = k × w × h²/ L

8 = k × 5 × 2² / 10

8 = k ×20/10

8 = 2 × k

k = 4

The maximum weight that could be supported by a beam that is 6 inches wide, 2 inches high, and 24 feet long

w =4 ×6 ×2² / 24

= 24 ×4/ 24

W=4 tons

Hence 4 tons is maximum weight that could be supported by a beam that is 6 inches wide, 2 inches high, and 24 feet long

Answer:

c) 3ft= 1 yards

18/3 = 6 yards

12/3 = 4 yards

Perimeter- 6×2+4×2=20 yards

6×4=24yards²

d) I foot= 12 inches

18ft = 12×18= 216"

12ft =12×12= 144"

Perimeter- 216×2+144×2= 720 inches

216"×144"= 31,104 inches²

Answer: C = b-(d/a)

Step-by-step explanation:

Given, a(b-c) = d

or, b-c = d/a

or, -c =(d/a)-b

or, c = b-(d/a)

Answer:

$180

Step-by-step explanation:

(12*10)+(12*5)

12*5 = 120/2 = 60 (half of 12*10)

12*10= 120

120 + 60= $180

You don't even have to calculate (12*5) you can just do 12*10/2

Answer:

y = -2/4x -5

Step-by-step explanation:

Assuming that the answer will be in slope intercept form, and not standard form. It would go a little like this:

Finding the slope:

y2 - y1/x2 - x1

-6 - (-4) / 2 -(-2)

-6 + 4 / 2 + 2

-2/4

Simplifying further, the slope would be: -1/2

The slope would be -1/2.

Now, checking desmos, the equation would be: y = -2/4x -5.

Answer:

Step-by-step explanation:

using sine formula

[tex]\frac{sinA}{a} =\frac{sinB}{b} =\frac{sinC}{c} \\\frac{sin \angle XYZ}{19} =\frac{sin 62}{24} \\sin \angle XYZ=\frac{19}{24} \times sin 62\\\angle ~XYZ=sin^{-1}(\frac{19}{24} \times ~sin~62) \approx 44.35^\circ[/tex]

Answer:

A.   Yes, there is a value that will maximize the profit overall x values. This is true when the functions C(x), R(x), and P(x) are often defined only for non-negative integers, that is, for x = 0, 1, 2, 3... . The reason is it is not logical to speak about the cost of producing −1 cars or the revenue generated by selling 3.62 refrigerators. Thus, each function may give rise to a set of discrete points on a graph.

The formulas for these questions are:

C(x) = cost of producing x units of the product

R(x) = revenue generated by selling x units of the product

P(x) = R(x) − C(x) = the profit (or loss) generated by producing and (selling x units of the product.)

B.  No, there is not an x-value that will maximize the profit over [0,1000]. This is true since 1,000 is the horizontal asymptote, which means that the line of the graph keeps traveling with the HA until the profits drop since we cannot produce anything more than 1,000 units of energy per day. The graph of this problem would be a horizontal asymptote at y = 1,000. The line of the graph would start at zero and increase until it reaches the asymptote at 1,000 and continues towards infinity.

C.  Yes, there is an x-value that is exactly zero. This is true because zero is our starting point in our profits. The x and y value would be (0,0) as we have just begun to produce energy units. Once the graph starts to increase, we cannot have a point at exactly zero, unless the profits have a dramatic drop to the x value of 0. This would then be (0, at a number of diminishing returns)

Step-by-step explanation:

The equation of perpendicular line is [tex]$y=-\frac{11}{6} x+\frac{43}{6}[/tex].

The equation of the straight line is represented by

y = mx + c

where m is the slope , and c is the intercept on y axis.

Calculate the slope m of BC using the slope formula

[tex]$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$[/tex]

with [tex]$\left(\mathrm{x}_{1}, \mathrm{y}_{1}\right)=\mathrm{B}(8,4)$[/tex] and [tex]$\left(\mathrm{x}_{2}, \mathrm{y}_{2}\right)=\mathrm{C}(-3,-2)$[/tex]

[tex]$m_{B C}=\frac{-2-4}{-3-8}=\frac{6}{11}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]$m_{\text {perpendicular }}=-\frac{1}{m}=-\frac{1}{\frac{-6}{11}}=-\frac{11}{6}$[/tex], then

[tex]$y=-\frac{11}{6} x+c[/tex]  is the partial equation

To find c substitute A(3,8) into the partial equation

[tex]$9=-\frac{-11}{6}+C[/tex]

[tex]$-\left(-\frac{11}{6}\right)+C=9$$[/tex]

Apply rule -(-a)=a

[tex]$\frac{11}{6}+C=9$$[/tex]

Subtract [tex]$\frac{11}{6}$[/tex] from both sides

[tex]$\frac{11}{6}+C-\frac{11}{6}=9-\frac{11}{6}$$[/tex]

Simplify

[tex]$C=\frac{43}{6}$$[/tex]

[tex]$y=-\frac{11}{6} x+\frac{43}{6}[/tex] be the equation of perpendicular line.

Therefore, the value of c = 43/6.
