Step-by-step explanation:

Let the 3-digit number is abc = 100a + 10b + c.

We have:

Simplify the first equation:

Solve for c by substitution:

Find a:

Find b:

The number is:

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

Median = 18+19/2

= 18.5

Answer:

Step-by-step explanation:

ΔABD ≅ ΔACD    {A S A congreunt}

∠ADB ≅ ∠ADC   {CPCT}

∠ADB + ∠ADC = 180   {linear pair}

2∠ADB = 180

∠ADB = 180/2

∠ADB = 90

∠ADB = ∠ADC = 90.

So, now we can use Pythagorean theorem to find x

x² = 8² - 2²

   = 64 - 4 = 60

x = √60

A and C would be your answer

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

Let's Simply :

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)

Answer:

Step-by-step explanation:

Identity used: [tex]a^{2}-b^{2} = (a + b)(a -b)[/tex]

81 = 9*9 = 9²

a = x^2 and  b =9

Then again 9 = 3*3.In this way, (x² - 9 ) can be again factored

[tex]x^{4} - 81 = (x^{2})^{2}-9^{2}\\\\=(x^{2} + 9)(x^{2} - 9)\\\\=(x^{2}+9) (x^{2} -3^{2})\\\\= (x^{2} + 9}(x+3)(x-3)[/tex]

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.

Step-by-step explanation:

line A and D are parallel because they have the same koeficient 3=3

line C is perpendicular to line A because

k1*k2=-1

3*(-1/3)=-1

which is a true statement

Answer:

a) Line D is parallel to line A

b) Line C is perpendicular to line A

Step-by-step explanation:

Line A has a slope of 3 and y intercept of 6

Line C is perpendicular to A as perpendicular lines have negative reciprocal slopes. Slope of C is -1/3

Line D is parallel to A as parallel lines have identical slopes but different y intercepts. Slope of D is 3 and y intercept is -1/3

Line B mirrors Line A over the y axis. It's slope is the negative of A and it has an identical y intercept.
