Answer:

B. 0.3

Step-by-step explanation:

sin²(t) + cos²(t) = 1

sin²(t) + 0.1² = 1

sin²(t) = 1 - 0.01 = 0.09

sin(t) = √(0.09) = 0.3

AlekseyPX

Answer:

t_o = 3, so solution exists on (0,4).

Step-by-step explanation:

Use Theorem

Divide equation with t(t — 4).

y''+[3/(t-4)]*y'+ [4/t(t-4)]*y=2/t(t-4)

p(t)=3/t-4—> continuous on (-∞, 4) and (4,∞)

q(t) = 4/t(t-4) —> continuous on (-∞,0), (0,4) and (4, ∞)

g(t) = 2/t(t-4)—> continuous on (-∞, 0), (0,4) and (4,∞)

t_o = 3, so solution exists on (0,4).

Lin runs 5 laps around a track in 6 minutes how many laps per minute is that

pychu [463]

Lin runs 5 laps around a track in 6 minutes. It is 0.83 laps per minute

Step-by-step explanation:

Simple division will be used to solve the given problem.

We hvae to calculate laps per minute which will be calculated by dividing the number of laps by total time in minutes.

Given

Laps = l =5

Time = t =6 minutes

Then

$Laps\ per\ minute = \frac{l}{t}\\=\frac{5}{6}\\=0.83\ laps\ per\ minute\\$

Lin runs 5 laps around a track in 6 minutes. It is 0.83 laps per minute

The midpoint of AB is M(1, -4). If the coordinates of A are (-3,-6), what are the coordinates of B?

kramer

Answer:

The coordinates of B is (5,-2)

Step-by-step explanation:

In order to find the coordinates of B, you have to use midpoint formula. Then substitute the following values into the formula :

$m = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2} )$

Let (x1,y1) be A (-3,-6),

Let (x2,y2) be B,

Let midpoint be M (1,-4),

$(1, - 4) = (\frac{ - 3 + x2}{2} , \frac{ - 6 + y2}{2} )$

$by \: comparison, \:$

$\frac{ - 3 + x2}{2} = 1$

$- 3 + x2 = 2$

$x2 = 5$

$\frac{ - 6 + y2}{2} = - 4$

$- 6 + y2 = - 8$

$y2 = - 2$
