Using the identity sin^2(t)+cos^2(t)=1
and 
given sin(t)=0.3,
we can find cos(t) by substituting
sin^2(t)+cos^2(t)=1
0.3^2+cos^2(t) = 1
cos^2(t)=1-0.3^2=1-0.09=0.91
cos(t)=sqrt(0.91)= 0.954  ≠  0.6
So the given proposition is false.

Answer:

D) y = -1/2x + 4

Step-by-step explanation:

Points on the graph: (0, 4) and (8, 0)

Slope:

m=(y2-y1)/(x2-x1)

m=(0 - 4)/(8-0)

m= -4/8

m = -1/2

Slope-intercept:

y - y1 = m(x - x1)

y - 4 = -1/2(x - 0)

y - 4 = -1/2x

y = -1/2x + 4

Aloiza [94]

Answer:

407 yd^{2}

Step-by-step explanation:

first find the area of the rectangle, which would be 16*13 = 208yd²

then find the arc length of the sector, which is about 30.6yd

use the arc length to find the area of the sector, which is about 199.09yd²

add together the area of the rectangle and sector:

199.09 + 208 ≈ 407

Point A is located at (-2, 2). Point B is located at (-2, 0). What is the distance between point A and point B ?
Andrew [12]

Answer:

2

Step-by-step explanation:

Both point a and b have an x value of -2 so to find the distance between the two points we simply have to find the horizontal distance. We can do this by subtract the y value of the first point by the y value of the second point.

Point A y value : 2

Point B y value : 0

Distance between Point A and Point B : 2 - 0 = 2 units
