Answer:
Step-by-step explanation:
Height of wall = 10ft
Length of ladder = 12ft
Angle of elevation be x
Sin x = opp/hyp
Sin x = wall height/length of ladder
Sin x = 10/12
Sin x = 0.83
X = Sin-¹ (0.83)
X = 56.44°
Step-by-step explanation:
x= -7 y=0
x= -3 y =-6
y =mx+b
b=-7
-6= -3m -7
-3m = 1
m= -1/3
y= -x/3 -7

Kendra is going faster. You could convert Kendra's measurement to feet per second by doing to following:
0.25 mi/1 min x 5280 ft/1 mi x 1 min/60 sec
Which equals:
(0.25)(5280)ft/60 sec
Simplify, and Kendra's speed is 22 feet per second.
mi= mile(s)
min= minute(s)
ft= feet
sec= second(s)

Step-by-step explanation:
-3 ? 
-3 ? -3.8
-3 is greater than -3.8
i.e -3 > -3.8
