Answer:
Step-by-step explanation:
hypotunes isnt involved(as the length inst given and we know it is hypotunes as it is the oppisite direction from the right angle)
so sohcahtoa
therefore ir toa
tan(x)=o/a
(tan inverse)tan^-1=34/54
oppisite= 34 as it is oppisite to teh angle your trying to find
and the adjacent is beetwen the right angle and the angle your mesuring
Answer:
a) d'(t) = 32t
The units of d'(t) are ft/s and it gives how fast or how slow the object is falling.
b) The ledge is 784 ft high
And just when the stone strikes the ground, it's moving at a speed of 152.73 miles/hour
Step-by-step explanation:
d(t) = 16t²
a) d'(t) = (d/dt)(d) = (d/dt) (16t²) = 32t
Since it is a time derivative, the units are ft/s and it describes the rate of change of the distance of falling object; more plainly, it gives how fast or how slow the object is falling.
b) d(t) = 16t²
If t = 7 s, how high is the ledge?
d(7) = 16 (7²) = 784 ft
How fast is the stone moving when it strikes the ground (in miles per hour)?
d'(t) = 32t
d'(7) = 32 × 7 = 224 ft/s
In miles/hour
224 ft/s = 224 ft/s × (1 mile/5280 ft) × (3600s/1 hr) = 152.73 miles/hour

Answer:
c=a+b-180
Step-by-step explanation:
Since the equation is a+b-c=180, you subtract a and b from both sides, meaning it would be -c=-a-b+180, then you must multiply both sides by -1, and the answer would come out to c=a+b-180.
