Fofino [41]3 years ago
3 0

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

3x+5y\leq 9 ----> inequality A

The solution of the inequality A is the shaded area below the solid line 3x+5y=9

2x+y\geq 5 -----> inequality B

The solution of the inequality B is the shaded area above the solid line 2x+y=5

Using a graphing tool

The solution of the system of inequalities is the shaded area indicated in the attached figure

The manufacturer of a CD player has found that the revenue R (in dollars) is R(p)= -4p2+1200p, when the unit price is p dollars.
qaws [65]

Answer: 9000$

Step-by-step explanation:

Let 's use the formula to find the vertex of the parabola:

ax²+bx+c=0

\displaystyle x_v=-\frac{b}{2a}  \\\\  Where :\\\\ y_v- maximum \ \  income \\\\ y_v=a(x_v)^2+bx_v+c \\\\ Then \ in \ \ our \ \ case : \\\\ -4p^2+1200p =0 \\\\ x_v=-\frac{1200}{-4\cdot 2} =150 \\\\  y_v=-4\cdot (150)^2+150\cdot 1200 \\\\ y_v=150\cdot 1200-150\cdot 600 \\\\ y_v=600\cdot 150=\bf 9000 \

The base of a triangular sail is 16 m shorter than its height. The area is 96 m squared . Find the base and height of the sail.
HACTEHA [7]

Answer:

Step-by-step explanation:

Lets start by labeling the triangle. Lets say the height is x and the base is x-16.

Next, we know the area of the triangle is 96, so we should make an equation. The area (96) of a triangle is (b*h)/2. So lets substitute.

96=[(x-16)*x]/2

Now, we should simplify the equation. Let us start by moving the /2 to the other side and making it *2.

192=(x-16)*x

Open parenthesis and get

192=x^2-16x

simplify and get

x=24

x is the height so the base must be x-16.

base=8, height=24
