Answer:
A) -1/3
Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
y = -1/3x + 2
m = -1/3
supplementary angles add up to 180 degrees
angle 1 = x
angle 2 = 8x
x +8x = 180
9x = 180
x = 180/9 = 20 degrees
larger angle = 8*20 = 160 degrees
Answer:
C. 98.0%
Step-by-step explanation:
If t represents 35 days, then in order to find the daily decay rate we will have to input 1/35 as the value of t.
100(0.5)^
= 98.039
The daily decay rate is 98.0%
Answer & Explanation:
To find the direction cosines of the vector a is need to divided the corresponding coordinate of vector by the length of the vector. The coordinates of the unit vector is equal to its direction cosines. Property of direction cosines. The sum of the squares of the direction cosines is equal to one.
Y-y1=m(x-x1)
y-5=1/6(x-8)
y-5=1/6x-4/3
-1/6x+y=11/3
multiply both sides by -6
x-6y=-22
