Answer all of these for 100 points
KiRa [710]

Answer:

Step-by-step explanation:

37) Take two point from the line.

(2 , 0)  & (0,4)

Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\frac{4-0}{0-2}\\\\=\frac{4}{-2}\\\\=-2

Slope = (-2)

38)  (7 , 0) & (3 , 2)

Slope = \frac{2-0}{3-7}\\\\=\frac{2}{-4}\\\\=\frac{-1}{2}

39) The line is parallel to x-axis and so its slope is 0

Slope = 0

40) The line is parallel to y-axis and so its slope is undefined

Slope = undefined

The integers are -17, 32, and -1.

Integers are actually whole numbers that can carry a negative sign (-) before it. Fractions and decimals are not integers.

Hope it helps.

What is the area of the composite figure if AB ≅ BC ≅ CD ≅ DA ≅ DN?
bekas [8.4K]

Answer:

Option 3. (2π + 40) mm².

Step-by-step explanation:

Area of the composite figure = area of MKCD + area of ABCD + area of semi circle with AB as diameter.

Then Area A = (DC + MK)/2 × DN + AB² + (1/2)×π×2²

                     = (4 + 8)/2 × 4 + 4² + (1/2)×π×4

                     = 24 + 16 + 2π = (2π + 40) mm²

Therefore option 3. (2π + 40) mm².
