Find the distance between the two points rounding to the nearest tenth (if necessary).
leonid [27]

Answer:

\boxed {\boxed {\sf d\approx 4.2}}

Step-by-step explanation:

The formula for distance is:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2

Where (x₁, y) and (x₂, y₂) are the points.

We are given (-6, 6) and (-3, 3). If we match the value and its corresponding variable, we see that:

  • x₁= -6
  • y₁ = 6
  • x₂ = -3
  • y₂ = 3

Substitute the values into the formula.

d= \sqrt{ (-3 - -6)^2+(3-6)^2

Solve inside the parentheses.

  • -3 --6 = -3+6 = 3
  • 3-6 = -3

d= \sqrt{(3)^2+ (-3)^2

Solve the exponents.

  • (3)²= 3*3= 9
  • (-3)²= -3*-3 =9

d= \sqrt{9+9

Add.

d= \sqrt18

d= 4.24264069

Round to the nearest tenth. The 4 in the hundredth place tells us to leave the 2 in the tenth place.

d \approx 4.2

The distance between the two points is apprximately <u>4.2</u>

Find all solutions of the equation sin^2 x=2sinx+3
Mashutka [201]
\sin^2x=2\sin x+3
\sin^2x-2\sin x-3=0
(\sin x-3)(\sin x+1)=0

which means either \sin x=3 or \sin x=-1. The equation has no solution, since \sin x is always bounded between -1 and 1. The second has one solution at x=-\dfrac\pi2, and any number of complete revolutions will also satisfy this equation, so in general the solution would be -\dfrac\pi2+2k\pi where k is any integer.

So you could choose A=-\dfrac\pi2 and B=2.
