Triangle IJK, with vertices I(3,-8), J(9,-7), and K(5,-4), is drawn inside a rectangle, as shown below. What is the area, in squ
MA_775_DIABLO [31]

Answer:

11 sq units

Step-by-step explanation:

(6×4) - ½(6×1 + 4×3 + 2×4)

= 24 - ½(6+12+8)

= 24 - ½(26)

= 24-13

= 11 sq units

Find the probability that a point is chosen randomly inside the rectangle is in each given shape...
BaLLatris [955]

Answer:

  1. <u>0.25</u>
  2. <u>0.85</u>

Step-by-step explanation:

P (Triangle or Square) :

  • Area of Triangle + Area of Square / Area of Rectangle
  • 1/2 x 3 x 4 (height is found by Pythagorean Theorem) + (3)² / 10 x 6
  • 6 + 9 / 60
  • 15/60
  • <u>0.25</u>

<u></u>

P (Not the square) :

  • Area of rectangle - Area of square / Area of rectangle
  • 60 - 9 / 60
  • 51/60
  • 17/20
  • <u>0.85</u>

How would I do the steps to solve this?
allsm [11]

Answer:

The maximum revenue is 16000 dollars (at p = 40)

Step-by-step explanation:

One way to find the maximum value is derivatives. The first derivative is used to find where the slope of function will be zero.

Given function is:

R(p) = -10p^2+800p

Taking derivative wrt p

\frac{d}{dp} (R(p) = \frac{d}{dp} (-10p^2+800p)\\R'(p) = -10 \frac{d}{dp} (p^2) +800 \ frac{d}{dp}(p)\\R'(p) = -10 (2p) +800(1)\\R'(p) = -20p+800\\

Now putting R'(p) = 0

-20p+800 = 0\\-20p = -800\\\frac{-20p}{-20} = \frac{-800}{-20}\\p = 40

As p is is positive and the second derivative is -20, the function will have maximum value at p = 40

Putting p=40 in function

R(40) = -10(40)^2 +800(40)\\= -10(1600) + 32000\\=-16000+32000\\=16000

The maximum revenue is 16000 dollars (at p = 40)

PLEASE HELP GUYS RIGHT NOW!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Margarita [4]

Answer:

Im on the same question so dont copy word for word

Step-by-step explanation:

The first error he made is that he didn't do the right steps in order to find the area of the two triangles. Instead he should have done 0.5 X 16 X 15 X 2= 240

Then the area for the three rectangles should be 16 X 8 + 17 x 8 + 17 X 8 = 400

If you add it all together, the surface area is actually 640 square meters.
