Answer:

$426.96 \: {km}^{2}$

Step-by-step explanation:

Area of the shaded region = Area of triangle with base 40 km and height 27 km - Area of circle with radius (12/2) 6 km.

$= \frac{1}{2} \times 40 \times 27 - 3.14 \times {(6)}^{2} \\ \\ = 20 \times 27 - 3.14 \times 36 \\ \\ = 540 - 113.04 \\ \\ = 426.96 \: {km}^{2}$

1. What is the slope of the line tangent to the curve defined by y2 + xy - x2 = 11x at the point (2, 3)?

andreyandreev [35.5K]

Step-by-step explanation:

By using Implicit Differentiation,

d/dx (y² + xy - x²) = d/dx (11x)

d/dx (y²) + d/dx (xy) - d/dx (x²) = 11

2y * dy/dx + x * dy/dx + y - 2x = 11

dy/dx (2y + x) = 11 + 2x - y

dy/dx = (11 + 2x - y) / (2y + x).

At the point (2, 3), we have x = 2, y = 3.

=> dy/dx = (11 + 2(2) - (3)) / (2(3) + (2))

= 12 / 8 = 1.5.

P.S. Your question is weird because (2,3) is not on the graph, let me know what is the correct question thanks!

Julia correctly estimated the value of 183 ÷ (76 – 15) + 29 by rounding each number to the nearest ten. What was Julia’s estimat

Vinvika [58]

Answer:

2 using PEMDAS

Step-by-step explanation:

First, I would round all numbers (to the nearest tenth).

183 rounds to 180

76 rounds to 80

15 rounds to 20

29 rounds to 30.

Now plug those numbers into the equation.

180/(80-20)+30

Using PEMDAS, I solve the parentheseis first.

80-20=60.

180/60+30

Then, add 60+30.

60+30=90.

you get 180/90.

180/90=2.
