Answer:
Step-by-step explanation:
Using a graphing calculator, plot (x,y) points
- x = no. of jobs
- y = no. of workers needed
and plot the functions from the options to know which function fits the data
Answer:
d. 2√34 cm
Step-by-step explanation:
Secant BD is the hypotenuse of right triangle ABD with legs given as AB = 6 cm and AD = 10 cm. Hence the Pythagorean theorem can be used to find BD:
BD = √(AB² +AD²) = √((6 cm)² +(10 cm)² = √136 cm = 2√34 cm
Sin x cos x ( tan x - 1) = 0
so one solution is tan x = 1 giving x = 45, 225 degrees ( for x 0 to 360)
sin x cos x = 0 so either sinx = 0 giving x = 0, 180, 360 degrees
or cos x = 0 giving x = 90, 270
answer is 0, 45, 90, 180, 225, 270, 360 degrees ( for 0 =< x >= 360)
