Write an equation in slope intercept form of the line containing the points (3,-1) and<br>(6,7).​
liq [111]

Answer:

m - 8/3

Step-by-step explanation:

Find the slope of the line between (-3,1) and (6,7) using m = (y2 - y1) / (x2-x1)

which is the change of "y" over the change of "x"

m = (7 - (-1) / 6 - (3)

m = 8/3

When an object is droppednbsp on a certain earth dash like planet comma on a certain earth-like planet, the distance it falls in
ANTONII [103]

Answer:

(a) s(44) = 3.52*10^{6}ft

(b) v(44) = 10*x^{5} ft/s

(c) a(44) = 3636ft/s^{2}

Step-by-step explanation:

s(t) = 1818t^{2}

(a) when t = 44sec

s(44) = 1818(44^{2}) = 1818(1936)\\ \\s(44) = 3519648ft

s(44) ≅ 3520000=3.52*10^{6}ft

(b) How fast the hammer is traveling i.e. the speed of the hammer.

To find speed, we differentiate the distance s(t) with respect to time, t

speed,v=\frac{ds(t)}{dt}=\frac{d}{dt}(1818t^{2})   \\\\v = 1818*2t^{2-1}= 1818*2t\\ \\v = 3636t

at t = 44sec,

v = 3636*44=159984ft/s

v ≅ 160000ft/s = 1.6*10^{5}ft/s

(c) The hammer's acceleration can be obtained by differentiating the speed v(t) with respect to time, t

acceleration, a = \frac{dv}{dt}=\frac{d}{dt}(3636t)\\  \\a = 3636*1= 3636\\\\a = 3636ft/s^{2}

There's no need to substitute t = 44sec because the acceleration is independent of time.

The following three shapes are based only on squares, semicircles, and quarter circles.
grin007 [14]

The perimeter of the shaded part is: 25.1 cm.

The area of the shaded part is: 36.6 cm².

<h3>How to Find the Perimeter and Area of the Shaded Part?</h3>

Area = Area of square - 2(area of square - area of quarter circle) = s² - 2(s² - 1/4πr²).

Parameters given are:

  • s = 8 cm
  • r = 8 cm

Plug in the values into the equation

Area = 8² - 2(8² - 1/4π(8²)).

Area = 64 - 2(64 - 50.3)

Area = 36.6 cm²

Perimeter = 2(perimeter of quarter circle) = 2(1/4(2πr)) = 2(1/4(2π8)) = 25.1 cm
