Profit = Revenue – Cost

To reach a point of breakeven, Profit = 0.

 

Therefore,

<span>Revenue =  Cost</span>

7x + 2 = 3x + 3

x = ¼

therefore the farm must produce at least ¼ tons of rice so that there will be no loss.

What areC12, C31, and C22 of matrix C?
Liono4ka [1.6K]

Compute the sum to simplify C :

C = \begin{bmatrix}16-0.5 & 9+0 \\ -3+5 & 0 + 8 \\ 4-3 & -10+14\end{bmatrix} = \begin{bmatrix}15.5 & 9 \\ 2 & 8 \\ 1 & 4\end{bmatrix}

Now, c_{ij} is the entry of the matrix in row i and column j, so

C = \begin{bmatrix}15.5 & \boxed{9} \\ 2 & 8 \\ 1 & 4\end{bmatrix} \implies c_{12} = 9

C = \begin{bmatrix}15.5 & 9 \\ 2 & 8 \\ \boxed{1} & 4\end{bmatrix} \implies c_{31} = 1

C = \begin{bmatrix}15.5 & 9 \\ 2 & \boxed{8} \\ 1 & 4\end{bmatrix} \implies c_{22} = 8

0 A two-inch-long grasshopper can jump a horizontal distance of 40 inches. An athlete, who is _ five feet nine, wants to cover a
Mkey [24]

Answer:

a) nearest jump is JL = 1380 inches = 115ft

b) number of jumps in 1 mile N= 46 jumps

Step-by-step explanation:

Given that the jump length is proportional to the body length.

If 2 inch grasshopper can jump 40 inches.

JL = k(BL)

k = JL/BL

where JL = jump length = 40 inches

BL = Body length = 2 inches.

k = 40/2 = 20

The constant of proportionality is 20.

For the athlete :

BL = 5ft 9 inches = 5(12)+9 = 69 inches.

The jump length of the athlete is:

JL = k(BL) = 20(69)

JL = 1380 inches. = 115ft

The number of jumps in 1 mile is

1 mile = 63360 inches

N = 63360/1380

N = 45.9 = 46

N= 46

Therefore, 46 jumps would be needed.

a plane rises from take-off and flies at an angle of 6 with the horizontal runway. When it has gained 900 feet, find the distanc
Vladimir79 [104]

Answer:

d=8610.1ft

Step-by-step explanation:

From the question we are told that:

Angle \theta =6\textdegree

Height of plane h=900ft

Generally the trigonometric equation for distance flown d is mathematically given by

  sin \theta=\frac{h}{d}

Therefore

 d=\frac{h}{sin\theta}

 d=\frac{900}{sin6}

 d=8610.1ft
